Audi moving ahead with 48V system in vehicles; mild hybrids
August 25, 2014
Audi will upgrade part of its vehicle electrical system from 12 to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars.
Audi recently showcased the scope of the 48-volt electrical system with the two technology demonstrators Audi A6 TDI concept and RS 5 TDI concept. (Earlier post.) Both models are fitted with an electrically powered compressor. This operates independently of the engine load and therefore fundamentally improves the acceleration performance. 48-volt technology is also suited for realizing convenience systems for dynamic chassis control. Audi will shortly be unveiling a variety of applications in this field.

The report will include analysis of the Department’s research findings in several key areas including technical feasibility, privacy and security, and preliminary estimates on costs and safety benefits, while the ANPRM seeks public input on these findings to support the Department’s regulatory work to eventually require V2V devices in new light vehicles.
DOE to award more than $55M to 31 projects for plug-in and efficient vehicle technologies; Delphi receives $10M to further GDCI
August 14, 2014
The US Department of Energy (DOE) is awarding more than $55 million to 31 new projects to accelerate research and development of vehicle technologies that will improve fuel efficiency and reduce costs under a program-wide funding opportunity announced in January. (DE-FOA-0000991, earlier post.) These new projects are aimed at meeting the goals and objectives of the President’s EV Everywhere Grand Challenge (19 projects), as well as improvements in other vehicle technologies such as powertrains, fuel, tires and auxiliary systems (12 projects).
The largest single award ($10 million) goes to Delphi Automotive Systems to further the development of its Gasoline Direct-Injection Compression Ignition (GDCI) low-temperature combustion technology (earlier post) that provides high thermal efficiency with low NOx and PM emissions. The largest number of awards (9) in a single area of interest goes to developing beyond Li-ion battery technologies.
GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord
August 11, 2014
|The assembled 200W TEG tested in June delivered 270W of output. Click to enlarge.|
GMZ Energy and its partners are on track to deliver a 1 kW thermoelectric generator (TEG) for the Bradley Fighting Vehicle as well as to design and to integrate a light-duty vehicle TEG into a Honda Accord as part of a DOE-funded project. Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power. GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MIT’s Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston.
The project is using Half-Heusler (HH) thermoelectric materials (earlier post) in designing the vehicular TEG systems. Although these materials (ferromagnetic intermetallic alloys with a strong crystal structure that allows great stability at high temperatures) have a ZT (dimensionless figure of merit) lower than some other TE materials such as Skutterudites, the mechanical strength and the reliability of HH compensates for this deficit, according to GMZ.

Ninety-seven percent of customers in the US who purchased a 2014 or 2015 Malibu—accounting for about 83,000 vehicles—opted for the 2.5-liter, 4-cylinder base engine (LKW) equipped with standard stop/start technology, according to GM. (Earlier post.) This marks the the most aggressive rollout of stop/start technology in the US by an American automaker.
The 2014 Malibu was the first in its segment with a standard engine featuring fuel-saving stop/start technology. Stop/start is featured along other technologies in the Malibu’s new 2.5L intake valve lift control (iVLC), powertrain along with direct injection, variable valve lift control and a new six-speed automatic transmission. All contribute to EPA-estimated fuel economy ratings of 25 mpg (9.4 l/100 km) in city driving and 36 mpg (6.5 l/100 km) on the highway—14% and 6% improvements, respectively, over earlier models.
Two Audi TDI technology studies with electric biturbo, 48V electrical systems; both technologies to go into series production
July 17, 2014
|V6 TDI bi-turbo with electric compressor. Click to enlarge.|
Audi has built two technology studies with the “electric biturbo” technology it is developing (earlier post): the Audi A6 TDI concept is equipped with a new 3.0 TDI monoturbo (i.e., a single turbo with supplementary electric compressor), while the Audi RS 5 TDI concept with a 3.0 TDI biturbo (two in-series turbochargers with supplementary electric compressor).
The electric biturbo system comprises a classic exhaust turbocharger (mono- or bi-turbo) working together with a supplemental, electric-powered compressor arranged in series and powered by a separate 48-volt electrical system. Instead of a turbine wheel, it contains a small electric motor that applies a maximum drive power of 7 kW to accelerate the compressor wheel to maximum speed within 250 milliseconds.

Continental’s powertrain developers have launched series production of the first car turbocharger with an aluminum turbine housing. Integration of the unit in the three-cylinder, 1.5L 100 kW gasoline engine for the MINI Hatch (earlier post) has been ongoing since spring 2014.
Water-cooling enables the use of the lightweight material and thus enables a significant weight reduction by nearly 30% while simultaneously providing cost and system benefits.
Navigant forecasts 40% of new vehicles in 2030 will have some form of autonomous driving capability; 75% by 2035
July 11, 2014
In a new research report (“Autonomous Vehicles”), Navigant Research forecasts that by 2030, about 40% of new vehicles sold will have some form of autonomous driving capability installed. The company expects this to increase to 75% by 2035.
Although the first vehicles with some self-driving capability will come to market in 2020, Navigant said, it expects it will take another 5 years before volumes become significant. By 2030—if the recent proposed changes to the Vienna Convention (which would allow autonomous vehicles with a driver control override) are approved—Western Europe will be slightly ahead on first implementation, but the much larger automotive markets in Asia Pacific and North America will eventually lead, according to the research firm.
Mercedes-Benz outlines synergies between F1 motorsport and production car engineering
July 10, 2014
Mercedes-Benz has outlined areas of actual synergies between its F1 motorsport activities with Mercedes AMG Petronas and Mercedes-Benz Cars. While there is definitely a technology transfer between race and road car engineering, said Paddy Lowe, Executive Director (Technical) at Mercedes AMG Petronas, “it’s a more subtle process than bolting bits from one car onto another.”
There are examples of direct transfer—such as the Nanoslide technology used to coat cylinder bore surfaces (earlier post)—and then there are examples of indirect transfer, such as F1 serving as a research laboratory for developing new solutions and showing the world what is possible, he noted.

Ford and Intel demonstrate in-car personalization with perceptual computing; Project Mobii
June 26, 2014
Ford and Intel are researching new opportunities for the connected car, including giving drivers the ability to remotely peer into their car using a smartphone, or a vehicle that could identify its owner using facial recognition software. The joint research project, called Mobile Interior Imaging, or Project Mobii, explores how interior-facing cameras could be integrated with sensor technology and data already generated within and around the vehicle to create a more personalized and seamless interaction between driver and vehicle that transforms the driving experience.
The Mobii research, which was showcased during the Go Further with Ford 2014 Trend Conference as part of the “Big Data” track this week in Dearborn, was a collaboration between Intel ethnographers, anthropologists and engineers alongside Ford research engineers. Mobii incorporates perceptual computing technology (now named RealSense by Intel) to offer a more enjoyable and intuitive vehicle experience.
CMU demo’ing Autonomous SRX in Washington this week
June 25, 2014
Researchers from Carnegie Mellon University (CMU) this week will demonstrate the CMU advanced Autonomous Cadillac SRX in Washington, DC. The car was brought to Washington at the request of Congressman Bill Shuster of Pennsylvania, who participated in a 33-mile drive in the autonomous vehicle between a Pittsburgh suburb and the city’s airport last September. Scheduled over two days, the demonstration will show how autonomous technology will eventually be fully integrated into vehicles that are currently on the market.
Developed with support from the National Science Foundation (NSF), the US Department of Transportation, DARPA and General Motors, the car is the result of more than a decade of research and development by scientists and engineers at CMU and elsewhere. Their work has advanced the underlying technologies—sensors, software, wireless communications and network integration—required to make sure a vehicle on the road is as safe—and ultimately safer—without a driver than with one. (In the case of the Washington, DC, demonstration, an engineer will be on hand to take the wheel if required.)

The technology behind Ford’s Lightweight Concept Vehicle; prospects for Mach-II with 50% mass reduction difficult
June 18, 2014
Earlier this month, Ford unveiled its Lightweight Concept vehicle, which uses advanced materials to explore future weight-reduction solutions that could improve performance and fuel efficiency while reducing CO2 emissions. The Ford Lightweight Concept reduces the weight of a 2013 Fusion to that of a Ford Fiesta, resulting in a nearly 25% weight reduction. (Earlier post.)
The Ford vehicle is based on the first phase (Mach-I) of work of the DOE-supported Multi-Material Lightweight Vehicles project (Award DE-EE0005574) by Vehma International (an engineering and prototype division within the Cosma International operating unit of Magna) and Ford. The $20.3-million project ($10 million from DOE, $10.3 million from Vehma/Ford) has two main objectives. First, to design and build the “Mach-I” prototype vehicle maintaining donor vehicle architectural space and using commercially available or demonstrated materials and processes while delivering a 22% reduction compared to the baseline vehicle. The result of this is reflected in the Ford concept.

Ford and Samsung outline R&D efforts for next-generation non-hybrid battery technology; dual-battery systems and lightweight Li-ion
In an event in San Francisco, Ford Motor Company and Samsung SDI, an affiliate of Samsung Group, outlined several collaborative research efforts on next-generation battery technology for non-hybrid vehicles. For the near term, they have been working on a dual-battery combining a lithium-ion battery with a 12-volt lead-acid battery that could enable regenerative braking technology in non-hybrid vehicles for greater fuel savings. Ford suggested the dual battery system might go into production soon.
Ford and Samsung SDI said they are also are researching a longer-term (e.g., about 10 years) ultra-lightweight lithium-ion battery that could one day supplant lead-acid batteries. The research advances lithium-ion battery technology currently available on Ford’s electrified vehicles.
Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter
June 02, 2014
Although gasoline direct injection engines (GDI) are a favorable technology for reducing fuel consumption and greenhouse gas emissions, recent studies have shown that GDI vehicles could emit more PM than traditional PFI (gasoline port fuel injection) vehicles as well as heavy-duty diesel trucks equipped with diesel particulate filters. This may result in the need for new emissions control strategies—such as a gasoline particulate filter (GPF)—to enable compliance with California LEV III and US EPA Tier 3 particulate emissions standards.
Now, a team from Environment Canada and Manufacturers of Emission Controls Association (MECA) report on an evaluation of emissions from two pairs of GDI and PFI (gasoline port fuel injection) vehicles over two different drive cycles and at different ambient temperatures to understand how solid particle number and BC mass relationships vary under the influence of different factors. Their paper appears in the ACS journal Environmental Science & Technology.

|Main components of the DIET-FI system. Click to enlarge.|
Global automotive supplier DENSO Corporation has developed a new electronic fuel injection system for small motorcycles called DIET-FI (DENSO Intelligent Economical Technology-Fuel Injection). DIET-FI is the first fuel injection system that doesn’t use a throttle position sensor or engine temperature sensor. Rather, it uses newly developed control technologies that ensure the same fuel economy and environmental performance as conventional fuel injection systems, thus cutting costs.
In the two-wheeler segment, fuel injection systems are usually only used in motorcycles; however, in recent years there has been a growing need to apply these systems to smaller motorized bikes up to the size of 150cc that are used in emerging markets, such as China.

This engine will be available only with a new seven-speed DSG gearbox and 4MOTION all-wheel drive. A plug-in hybrid model will also be offered, with potential to travel 31 miles (50 km) powered by a 9.9 kWh battery pack alone power alone, and with a potential combined maximum range of around 600 miles (966 km).
New Ford Transit debuts with new two-wet monocoat paint technology; improved durability and sustainability
|New two-wet monocoat paint process. Click to enlarge.|
Ford began production of the North American Transit at Kansas City Assembly Plant on 30 April, and vans will be available in US and Canada this summer. Transit vehicles built in Kansas City are the first to use a new two-wet monocoat paint process developed by Ford and its paint suppliers. The technology results in more durable paint, uses less energy and water, and reduces carbon dioxide and particulate emissions compared with conventional paint processes.
The new paint was subjected to testing simulating typical conditions the vehicle will see over 10 year—e.g., resistance to chipping and scratching, pollutants and sun exposure. Data from preliminary advanced weathering testing indicates that paint applied with the new two-wet technology will retain 90% of its gloss at four years in service compared to 1% gloss retention for paint applied using a conventional monocoat process.

April 30, 2014
UK Business Secretary Vince Cable recently announced the first four automotive technology projects to be funded by the Advanced Propulsion Centre (APC) (earlier post) with grants totaling £30.3 million (US$51 million); the projects that will help develop next-generation engines (including the Ford EcoBoost) and see Formula 1 technology applied in buses and excavators.
The jointly funded government and industry APC will invest around £1 billion (US$1.7 billion) over the next 10 years to develop, commercialize and manufacture greener and more efficient technologies for engines of vehicles of the future. The four projects are the winners of an up to £75 million competition that the Technology Strategy Board launched in partnership with the Department for Business, Innovation & Skills (BIS) and the Automotive Council in December 2013.
Dearman-led consortium awarded $3.1M to develop waste-heat-recovery system using liquid air engine
April 23, 2014
A consortium led by the Dearman Engine Company has been awarded £1.86 million (US$3.12 million) in the latest round of IDP10 funding from the UK’s Technology Strategy Board to support the development of a heat-recovery system for urban commercial vehicles. The tenth competition under the Low Carbon Vehicles Innovation Platform’s integrated delivery program (IDP), IDP10 is targeting the building of an integrated low-carbon-vehicle innovation chain, from the science base, through collaborative R&D to fleet-level demonstration.
The Dearman project is to deliver a production-feasible waste-heat recovery system for urban commercial vehicles, which offers life-cycle CO2 savings of up to 40%; fuel savings of 25%, with the potential of up to almost 50%; and potential payback in less than three years. The project uses the Dearman Engine, a highly-efficient liquid nitrogen or air (LiN) engine (earlier post) that harvests low-grade heat sources and, in this configuration, is most effective in urban duty cycles, working with the internal combustion engine (ICE) as a hybrid powertrain.
IHS: Renesas maintains dominance in $26.7B automotive semiconductor market
April 18, 2014
Renesas remained the leader in the automotive semiconductor market in 2013, with the company’s dominance in microcomponents and logic integrated circuits (IC) helping it to hold a half-billion-dollar gap over the second-place competitor, according to analysis by IHS Technology. Japan-based Renesas posted automotive semiconductor revenue of $2.9 billion last year, giving the company a market share of 11%. This compares to $2.4 billion in revenue and 9% share for the Nº 2 contender, Infineon of Germany, allowing Renesas to maintain the leading position it held in 2012.
Although the IHS ranking shows Renesas experienced a 14% decline in revenue for the year, the drop was entirely driven by a fluctuation in the exchange rate between the Japanese yen and the US dollar. When measured in terms of its native yen, Renesas’ automotive semiconductor revenue actually rose by about 5% in 2013 compared to 2012, according to IHS. The overall automotive semiconductor market expanded by 5% in 2013, according to IHS. Market revenue last year rose to $26.7 billion in 2013, up from $25.4 billion in 2012.

Subaru of America, Inc. introduced the 5th-generation 2015 Outback. The 2015 all-wheel drive Outback offers the roomiest interior, most capable chassis and highest fuel-efficiency in the model’s 20-year history.
New for 2015, all Outback models come standard with the Lineartronic CVT (continuously variable transmission), which features paddle-shift control switches and is instrumental in the Outback’s significantly improved fuel economy. Manufacturer-estimated ratings of 25 mpg city / 33 mpg highway / 28 mpg combined (9.4, 7.1 and 8.4 l/100 lm, respectively) for the Outback 2.5i model are up from 24/30/26 (9.8, 7.8 and 9.0 l/100 km, respectively) in the 2014 model—a 7.7% improvement in the combined figure.
LMU study finds 20% of gases from combustion of R1234yf MAC refrigerant consist of highly toxic carbonyl fluoride (correction and update)
April 11, 2014
Chemists at Ludwig Maximilians Universität München report that 20% of the gases produced by the combustion of R1234yf—the approved low global warming potential refrigerant for mobile air conditioning (MAC) systems, the adoption of which has met with resistance from German automakers (earlier post)—consist of the highly toxic chemical carbonyl fluoride.
Carbonyl fluoride is structurally related to phosgene (which contains chlorine in place of fluorine), which was used as a chemical weapon during the First World War. Kornath and his co-workers have just published the results of their investigation in the journal Zeitschrift für Naturforschung B.
ExxonMobil, Corning and Toyota develop onboard membrane system to separate gasoline into octane fractions to optimize engine efficiency and performance
April 10, 2014
ExxonMobil, Corning and Toyota have collaborated to develop an Onboard Separation System (OBS) to optimize gasoline engine efficiency and performance. OBS is a membrane-based process that separates gasoline into higher and lower octane fractions—essentially creating a dual fuel system from a single base fuel—allowing optimal use of fuel components based on engine requirements. The system, say the researchers, offers the potential to exploit most of the benefits of operating on premium high octane fuel while using less expensive regular grade more effectively.
In a paper on the OBS presented at the SAE 2014 World Congress, the researchers suggested that potential applications include downsizing to increase fuel economy by ∼10% while maintaining performance, and or using OBS with turbocharging to improve performance and knock resistance.
SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions
April 09, 2014
Southwest Research Institute (SwRI) announced preliminary test results of its Dedicated-Exhaust Gas Recirculation (D-EGR) demonstration vehicle (earlier post) at the SAE 2014 World Congress in Detroit. D-EGR is a SwRI-developed gasoline engine concept that uses in-cylinder fuel reforming to produce CO and H2 (with Research Octane Numbers of 106 and 130, respectively) and high levels of recirculated gas (EGR) to achieve very high levels of thermal efficiency.
The D-EGR demonstrator is a converted 2012 Buick Regal with a 2.0-liter gasoline direct injection engine. In their paper, the SwRI researchers reported that the conversion to D-EGR improved engine efficiency and fuel consumption at least 10% across the performance map, with some operating conditions seeing substantially higher improvements. The D-EGR engine offers efficiency similar to diesel engine (~40% BTE) but at half the cost; it also demonstrates the potential for meeting the very stringent LEV III/Tier 3 emissions.

The first two mainstream plug-in hybrid electric vehicles from the Volkswagen Group—e.g., not the $845,000 base price plug-in hybrid Porsche 918, earlier post, or even the $100,000 Porsche Panamera S E-Hybrid, earlier post—the Golf GTE (earlier post) and the A3 e-tron (earlier post), are both based on the same MQB (Modularen Querbaukasten, or modular transverse toolkit) plug-in hybrid powertrain.
The Volkswagen Group’s MQB modular toolkit is one of the four main modular toolkits (modularen Baukästen) of the Group: the MQB (transverse); the MLB (longitudinal); the MSB (standard drive); and the NSF (New Small Family). The toolkits standardize many vehicle component parameters across brands and vehicle classes, while at the same time offering access to new technologies, such as alternative drive systems. The new Mark 7 Golf, which is MQB-based, offers gasoline; diesel; natural gas; plug-in hybrid (the GTE); and battery-electric (the e-Golf) versions, all of which can be manufactured bumper-to-bumper on the same assembly line. The MQB spans the A0 to C segments.

The European Commission has approved the new ECO Thermo Cover engine compartment encapsulation in the Mercedes-Benz S 300 BlueTEC HYBRID (earlier post) as a manufacturer’s Eco-innovation. Insulating buildings saves energy; Mercedes engineers have adopted a similar idea in the car.
With insulating partitions in the engine compartment and a radiator shutter that is closed when the car is at a standstill, the heat inside the Mercedes-Benz S 300 BlueTEC HYBRID remains in the engine compartment, even if the vehicle is stopped for some time. When the engine is started again, the higher temperatures reduce friction in the engine, minimize cold-start losses, and cut CO2 emissions. Tests performed at Mercedes-Benz indicate an average fuel saving of up to 1.5 liters per full 70-liter tank (i.e., around 2.1%) over the course of a year.
Volvo Cars developing systems for Driver State Estimation; driver sensors
March 17, 2014
Volvo Cars is researching systems that can recognize and distinguish whether a driver is tired or inattentive. By placing a sensor on the dashboard to monitor aspects such as in which direction drivers are looking, how open their eyes are, as well as their head position and angle, it is possible to develop precise safety systems that detect a driver’s state and are able to adjust the car accordingly.
The analysis of the driver’s state, known as Driver State Estimation, in which driver sensors play an important role, is a field that may be key to self-driving cars in the future, Volvo suggests. The car will need to be able to determine for itself whether the driver is capable of taking control when the conditions for driving autonomously are no longer present. A driver sensor could be of assistance in this.

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies
December 13, 2013
Average new vehicle CO2 emissions rate and fuel economy in the US achieved record levels in MY 2012, and have improved in 7 of the last 8 years, according to the newly released Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 - 2013 (the annual “Trends” report) from the US Environmental Protection Agency (EPA). The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies.
The final model year (MY) 2012 adjusted, real world CO2 emissions rate is 376 g/mi—a 22 g/mi decrease (-5.5%) relative to MY 2011. MY 2012 adjusted fuel economy is 23.6 mpg (9.97 l/100 km), which is 1.2 mpg higher (+5.4%) than MY 2011. Both values represent all-time records since the database began in MY 1975, and the authors of the report believe that these represent historical records as well. The 1.2 mpg fuel economy improvement from MY 2011 to MY 2012 is the second largest annual improvement in the last 30 years.

Audi has released initial details on its new 2014-generation Audi R18 e-tron quattro LMP1 Le Mans prototype racer. Although the new diesel hybrid sports car appears like a continuous further development of the World Championship winning car and Le Mans winner of the past two years, due to the new LMP1 regulations that will come into effect in 2014, Audi Sport redeveloped every component.
In the new Technical Regulations, a large number of principal definitions, which concern the powertrain, body dimensions, safety and aerodynamics, were re-determined. With the new R18, Audi Sport has opted for a similar concept as in the past—albeit with new detailed solutions and an additional hybrid system. Powertrain elements include:

Protean Electric will also assist FAW-VW in the development of safety and vehicle controls that can be applied to additional vehicle programs.
New Bosch start-stop system with coasting mode can reduce fuel consumption by up to another 10%
December 11, 2013
Bosch has developed a new start-stop system with coasting mode; the system stops the engine when the vehicle is traveling at speed, helping to reduce fuel consumption by up to 10%. The function can be combined with any type of combustion engine.
First generation start-stop systems stop an engine only when the vehicle is completely stationary; enhanced versions of this start-stop system cut the engine as soon as the vehicle is coasting to a halt—e.g., at a red light. In contrast, as soon as the driver’s foot is off both the gas and the brake pedal, vehicles equipped with the new start-stop coasting function stop the engine while the vehicle is in motion. Because the engine is disengaged, the vehicle can coast for longer than it could with an overrun fuel cutoff system, for example.
Honeywell and suppliers to invest ~$300M to boost production of HFO-1234yf low GWP MAC coolant
December 10, 2013
Honeywell and key suppliers will invest approximately $300 million to increase production capacity for HFO-1234yf, its low global warming potential (GWP) refrigerant for mobile air conditioning (MAC) systems in automobiles. (Earlier post.) GWP is a relative measure of how much heat a greenhouse gas traps in the atmosphere, with carbon dioxide setting the comparison with a GWP of 1. HFO-1234yf’s GWP is 99.9% lower than that of HFC-134a, the current refrigerant in use (GWP = 1,300).
Among these investments, Honeywell will construct a high-volume manufacturing plant using new process technology at the company’s existing Geismar, Louisiana, refrigerants manufacturing site, which is expected to be fully operational in 2016. The exact size of the plant will depend on supply agreements that Honeywell is putting in place with major customers.

NREL review of E15 effects on MY2001 and later cars finds no meaningful differences with E10
October 13, 2013
A review of 43 studies of the effects of E15 (15% ethanol blends) on Model Year 2001 and newer cars by the National Renewable Energy Laboratory (NREL) found that the studies reviewed showed no meaningful differences between E15 and E10 in any performance category.
The NREL study, commissioned by the Renewable Fuels Association, included 33 unique research studies, as well as 10 related reviews. The study does not address engines that EPA has not approved for use with E15, such as pre-2001 cars, marine, snowmobile, motorcycle, and small non-road engines.
UC Irvine study finds organic constituents of UFP play important role in heart disease; suggestions for more effective emission control
October 12, 2013
|Particle scale. Inset: 4 polydisperse modes of traffic-related ambient particulate matter span approximately 4 orders of magnitude from below 1 nm to above 10 μm. Source: Kleinman presentation. Click to enlarge.|
Results of a study funded and released by the California Air Resources Board (ARB) suggest that the organic constituents of ultrafine PM (UFP, particles ≤ 0.18 μm aerodynamic diameter) resulting from internal-combustion engine exhaust and from chemical reactions in the air play an important role in the progression of heart disease, the leading cause of death in the US. The findings thus suggest a direction for mor effective emission control measures—i.e., technology for the removal of the organic constituents as well as the reduction of the number of particles.
Led by Dr. Michael T. Kleinman of the University of California Irvine, the new study used a novel approach to determine whether or not the toxicity of UFP particles depends on the concentration and composition of semi-volatile and non-volatile fractions of the PM.

|An electron microscope image shows graphene nanoribbons embedded in a block copolymer. Image by Changsheng Xiang. Click to enlarge.|
A new composite material created at Rice University is nearly impervious to gas and may lead to lighter and more efficient storage of compressed natural gas for vehicles. By adding modified, single-atom-thick hexadecyl-functionalized low-defect graphene nanoribbons (HD-GNRs) to thermoplastic polyurethane (TPU), the Rice lab of chemist James Tour made the resulting material far more impermeable to pressurized gas and far lighter than the metal in tanks now used to contain the gas.
In an open access paper in the journal ACS Nano, Tour and his colleagues at Rice and in Hungary, Slovenia and India reported that nitrogen gas effective diffusivity of the TPU was decreased by three orders of magnitude with only 0.5 wt% GNRs.

The approach centered on accurate detection of traffic environments using cooperative sensing and perception, comprehensive situation assessment to precisely evaluate collision risks, and subsequent activation of appropriate advance protection measures.
New valveless electro-hydraulic steering system for off-road equipment shows significant fuel savings and productivity benefits
Researchers at Purdue University have developed a new valveless hydraulic steering system for heaving construction equipment that improves efficiency and reduces fuel consumption. The new approach eliminates valves now needed to direct the flow of hydraulic fluid in steering systems and uses advanced algorithms and models to control hydraulic pumps precisely. New designs might also incorporate textured “micro-structured” surfaces inside pumps to improve performance.
Testing the new “electro-hydraulic power steering system” on a front loader has shown a 15% fuel savings and 23% increased machine productivity, for a total fuel efficiency increase of 43% during steering maneuvers. The findings are detailed in a research paper being presented during the SAE 2013 Commercial Vehicle Engineering Congress (1-3 October). The paper was authored by doctoral student Naseem Daher and Monika Ivantysynova, Maha Fluid Power Systems Professor in Purdue’s School of Mechanical Engineering, and director of Purdue’s Maha Fluid Power Research Center.

Researchers at the Korea Institute of Machinery and Materials (KIMM) have developed a new hybrid reactor for automotive exhaust aftertreatment that combines plasma and a honeycomb-structured monolith catalyst resulting in an enhanced synergistic effect of low-temperature catalytic activity.
As reported in a paper published in the ACS journal Environmental Science & Technology, the plasma−catalyst synergistic reaction is more effective at low temperatures; the hybrid reaction reduces the temperature required to achieve the same level of DRE (destruction and removal efficiency) for hydrocarbon (HC) pollutants when compared to the temperature of the reaction under the influence of the catalyst alone. As a result of their work, the authors suggest that the plasma−catalyst technology is feasible to control exhaust emissions from next-generation low-temperature combustion (LTC) diesel engines.

Researchers at USC have found that using recirculation rather than outside air ventilation in a car can effectively reduce in-cabin exposure to on-road particle pollution. In a study published in the ACS journal Environmental Science & Technology, they also report that in addition to the benefits of recirculation settings, exposures are lower in newer cars; at slower speeds; and on arterial roads, where pollutant concentrations are lower than on freeways.
Scott Fruin, assistant professor of preventive medicine, and Neelakshi Hudda, research associate in environmental health, both of the Keck School of Medicine of USC, performed a systematic study of in-vehicle exposure to include a full range of car types and operating conditions, as well as all types of particulate pollution. According to the researchers, concentrations of particle pollutants on freeways are often five to 10 times higher than elsewhere.

A team of researchers in the Institute for Integrated Catalysis at Pacific Northwest National Laboratory led by chemist János Szanyi has proposed a reaction mechanism for a highly active zeolite catalyst (Cu-SSZ-13) used in selective catalytic reduction (SCR) NOx aftertreatment systems for diesel emissions. A paper on their work is published in the journal Angewandte Chemie International Edition.
Although the catalyst is in use, exactly how it converts NOx to nitrogen and water with the help of ammonia (urea) hasn’t been entirely clear. The new research finds that the catalyst works much the same way that similar bacterial enzymes do: by coming at the target from the side rather than head on. The finding provides insight into how to make better catalytic converters.
Mercedes-Benz S-Class INTELLIGENT DRIVE drives autonomously over 100km interurban and urban route with near-production technology
|Networked sensor systems of the S 500 INTELLIGENT DRIVE research vehicle. Click to enlarge.|
Mercedes-Benz has demonstrated the feasibility of autonomous driving on both interurban and urban routes with its S 500 INTELLIGENT DRIVE research vehicle. The company set the vehicle to cover a 100 km (62-mile) route from Mannheim to Pforzheim—retracing that taken by motoring pioneer Bertha Benz exactly 125 years ago when she set off on the first long-distance drive.
The self-driving S-Class had to deal autonomously with a number of highly complex situations such as traffic lights, roundabouts, pedestrians, cyclists and trams. The successful drive was achieved with the aid of near-production-standard technology, very similar to that already found in the new E and S-Class. The project thus marks a milestone along the way that leads from the self-propelled (automobile) to the self-driving (autonomous) vehicle, the company said.

Ricardo is advancing its work with two novel technologies to improve the efficiency of heavy-duty goods vehicles: a cryogenic split-cycle engine “CryoPower” (earlier post), and a low-carbon waste-heat powered microwave fuel reformer “HeatWave II”.
Heavy duty vehicles, such as long haul trucks, represent a significant challenge in terms of the reduction of carbon dioxide emissions. An essential element of the transportation mix of modern industrialized society, they are inherently less amenable to the type of electrification and hybridization strategies that are already contributing to reduced carbon emissions and potential long-term sustainability for the light vehicle sector.
