Study suggests focusing on cold starts in gasoline cars as target for emissions reduction
August 22, 2016
A new study suggests that focusing on a gasoline-fueled vehicle’s cold start is the best target for future design changes to reduce emissions of criteria pollutants. The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS) in Philadelphia.
Although the Environmental Protection Agency (EPA) has reported that air is cleaner today than it was in the 1970s, more than 130 million people in the US still live in places where smog or particle pollution rises to unhealthful levels. Smog can cause coughing and shortness of breath, and can aggravate asthma or trigger asthma attacks. Much of this haze is formed from volatile organic compounds, or VOCs, and fine particulate matter from tailpipe emissions.

Audi developing electromechanical rotary dampers; potential for energy recuperation from suspension; 48V
August 10, 2016
Audi is developing a prototype electromechanical rotary dampening system called “eROT,” in which electromechanical rotary dampers replace the hydraulic dampers used today for an even more comfortable ride. The eROT system also offers the potential for energy recuperation from the suspension.
Every pothole, bump, and curve in the road induces kinetic energy during compression and rebound of the car’s suspension, observes Dr.-Ing. Stefan Knirsch, Board Member for Technical Development at AUDI AG. “Today’s dampers absorb this energy, which is lost in the form of heat. With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.”

Continental to demonstrate dynamic eHorizon technology during CES; Connected Energy Management and Blind Curve Warning
Continental will demonstrate its latest generation of eHorizon technology during CES next month in Las Vegas. Continental will show with two use cases based on dynamic eHorizon technology—Connected Energy Management and Blind Curve Warning—how data from the cloud can predict the road ahead, ultimately reducing fuel consumption and making vehicles safer. Both demonstrations will be conducted on public roads in Las Vegas.
Continental has already shown that the static eHorizon—introduced commercially in 2012—which uses certain data from a static map stored in the vehicle, enables a significant reduction of fuel consumption (around 3% on average). As a result of this success, Continental has taken the development of eHorizon even further by using the cloud and crowd intelligence to enhance the digital map in the dynamic eHorizon Backend with fresh and accurate information.

Westport and GTI awarded $900,000 to advance natural gas combustion technology; ESI with high frequency corona discharge ignition
December 09, 2015
Westport Innovations Inc., together with the Gas Technology Institute (GTI), has been awarded US$900,000 towards a program to advance state-of-the-art natural gas combustion technology. The work will feature Westport’s enhanced spark ignited (ESI) natural gas engine technology (earlier post) with the integration and demonstration of high frequency corona discharge ignition on an original equipment manufacturer (OEM) partner’s engine. The engine has a displacement of between 1 and 1.5 liters per cylinder and is targeted at medium-duty commercial vehicle applications.
Using 100% dedicated natural gas as fuel, Westport’s ESI technology optimizes the combustion and thermal efficiencies of the engine by taking full advantage of the ultra-high octane performance fuel properties of natural gas. The technology enables a “downsized” natural gas solution that is cost-competitive while providing similar levels of power, torque, and fuel economy to a larger diesel engine.

With more than 1,200 customers for its first product, Piksi, the company has already experienced high demand for its low-cost, high-performance GPS receiver.
Audi’s production electric e-tron quattro may set a new standard for vehicle handling; advanced vehicle dynamics control
December 01, 2015
The production version of Audi’s battery electric e-tron quattro SUV (earlier post), due out in 2018, is an important vehicle for the brand, and especially for Audi of America, which is driving many of the requirements for the C-segment electric SUV. At the LA Auto Show, Audi of America President Scott Keogh said that the brand is targeting at least 25% of its US sales to be e-tron—i.e., plug-in hybrid or full electric—models by 2025. (Earlier post.)
He also observed, in a conversation on the eve of the LAAS, that if an automaker can launch a defining product, the game changes. Audi intends for the e-tron quattro to become such a defining product—an Audi electric SUV in the high-volume C-segment that is reasonably priced (in the luxury sector) and delivers longer range along with all the “known” benefits of electric drive: speedy acceleration, quiet, lower cost of fueling, and zero tailpipe emissions (as well as the high-value HOV sticker for some markets). But to make this a benchmark product, Audi intends to go further, leveraging the three-motor electric quattro powertrain through very advanced software controls to deliver a ride and handling experience not possible even in an all-wheel drive electric vehicle equipped with a torque vectoring differential mechanism (e.g., a Tesla).

November 12, 2015
The Carbon Core body structure of the new BMW 7 Series has been awarded the EuroCarBody Award 2015 at the 17th Global Car Body Benchmarking Conference. The body of the new BMW luxury sedans was given a rating of 41.87 out of 50 possible points—the best score ever to be obtained in this competition. The EuroCarBody Award has been announced at the annual conference of experts every year since 2002 and is regarded as a leading award for innovations in car body construction.
The Carbon Core used for the body structure is the central element of the BMW EfficientLightweight Technology that was applied particularly consistently in the development of the sixth generation of the BMW 7 Series. For the first time in a volume-production automobile, a composite of CFRP, aluminium and super high-strength steels was created which increases rigidity and stiffness in the passenger cell while at the same time significantly reducing the vehicle weight.
2017 Cadillac XT5 initiates new series of Cadillac luxury crossovers; cylinder deactivation and stop/start
November 10, 2015
Cadillac unveiled the first 2017 Crossover Touring 5 (XT5), a comprehensively upgraded luxury crossover and the cornerstone of a new series of crossovers. Cadillac crossovers will wear the “XT” designation. The XT5 premieres this month at the Dubai and Los Angeles auto shows and begins production in the US and China in spring 2016.
The new luxury crossover joins Cadillac’s lineup immediately following the new range-topping CT6 Sedan, as the brand enters a new phase of product growth. In the US market, the 2017 Cadillac XT5 will be powered by the new 3.6-liter V6 engine which debuted earlier this year on the brand’s ATS and CTS sport sedans and is featured on the CT6. This engine has been completely redesigned and features Active Fuel Management cylinder deactivation technology, which allows the engine seamlessly and automatically to switch to a fuel-saving 4-cylinder mode under low or moderate loads.
Frost & Sullivan forecasts Gasoline Particulate Filters to climb from 50,335 units now to 4.2-4.6 million units by 2020
November 08, 2015
Gasoline direct injection (GDI) is a strategy to improve fuel efficiency that is rapidly gaining market acceptance. However, unlike conventional gasoline engines, gasoline direct injection engines produce particulate matter, as do diesels, and emission controls will become an issue the technology must address as standards for particle mass tighten, and also as standards for particle numbers emerge.
In a 2013 study, a team from Ford’s Research and Advanced Engineering group in Dearborn noted that because the efficiency advantage of homogeneous GDI is not as large as with diesel engines, the use of gasoline particulate filters (GPF) is a less practical solution to PM emissions aftertreatment. Accordingly, there are significant research efforts—including Ford’s own—aimed at understanding how PM emissions can be reduced by engine design (e.g., fuel injection timing, number of injections, fuel pressure, injector placement, etc.) and fuel properties. (Earlier post.) Nevertheless, Frost & Sullivan projects the number of engines equipped with GPFs will climb from 50,335 units today to 4.2–4.6 million units by 2020.

Aeristech developing turbomachine-type electric air compressors for fuel cells; claims potential doubling of output
October 27, 2015
UK-based Aeristech, a provider of electrically driven pressure charging solutions (earlier post), is developing electric air compressor technology that the company says could double the output from a hydrogen fuel cell. The electric compressor would enable vehicle manufacturers to increase performance or to specify a considerably more compact fuel cell, improving packaging and weight.
The Aeristech fuel cell compressor uses an aluminium, turbomachine-type compressor with volume automotive manufacturing tolerances, direct-coupled to a variable high-speed motor with no transmission. This represents a significant change from roots- and screw-type compressors.

Mercedes-Benz to begin equipping top models with CO2 air conditioning systems starting in 2017; adapting other models for R1234yf
October 20, 2015
From 2017, Mercedes-Benz will offer in Europe the S- and E-Class as the first production passenger cars equipped with CO2 air conditioning systems. These completely newly developed systems are based on the DIN specifications defined by the automotive standards committee of the German Association of the Automotive Industry (VDA).
Due to especially quickly available and high cooling performance, CO2 air conditioning systems swiftly provide for a pleasant feel-good climate inside vehicles even in very hot weather, the company said, while at the same time complying with legal requirements for low global warming potential refrigerants and avoiding the use of R1234yf, which Mercedes has found problematic. (Earlier post.)
GM and LG expand their relationship on Bolt EV; 12 components, including PEEM
GM and LG announced an expanded and deepened relationship around the coming Bolt battery-electric vehicle (earlier post), with LG providing not only the battery pack and battery heater, but also the critical PEEM (power electronics and electric machine) components; the HVAC electronic climate control system compressor; telematics hardware for OnStar; and the instrument cluster and infotainment system displays.
In a media briefing, Mark Reuss, GM executive vice president – global product development, purchasing and supply chain, observed that the expanded strategic partnership with LG marked a significant new approach to the adversarial automaker-supplier relationships of the past. Further, he noted, such a new type of relationship would be essential for electric vehicles. “The Bolt EV will be the result of an entirely different PEM/supplier relationship.”
Toyota bringing advanced ITS technology to mass-market models in Japan; V2X
September 30, 2015
By the end of 2015, Toyota will make a new ITS (Intelligent Transportation System) safety package available on three models in Japan. The package, named ITS Connect, uses Japan’s standardized ITS frequency of 760 MHz to receive and share data transmitted by external infrastructure and other vehicles. Equipping ITS on these three models will make Toyota the world’s first automaker to bring a driver assist function that uses a dedicated ITS frequency to market.
ITS Connect uses vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication (collectively V2X) to provide drivers with the kind of safety information that cannot be picked up by onboard sensors. This includes traffic signal information and information about the presence of vehicles and pedestrians in blind spots.
Renesas introducing R-Car W2R 5.9 GHz automotive wireless communication SoC for V2X communication
Renesas Electronics Corporation announced the R-Car W2R system-on-a-chip (SoC), the first member of the new Renesas R-Car Family of devices developed specifically for V2X applications. The new automotive wireless communication SoC is designed for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication in the 5.9-gigahertz (GHz) band.
Through the use of Renesas’ exclusive RF system design technology, the R-Car W2R is the first in the world to succeed in suppressing out-of-band transmission signal noise below the -65 dBm stipulated by the European Telecommunications Standards Institute (ETSI). This makes it possible for products that use the R-Car W2R to achieve the best noise characteristics in the world. This enables high-quality signals with little interference to be transmitted, making it possible to implement vehicle-to-everything (V2X) at a practical level in various kinds of ADAS systems for supporting safe driving.
Schaeffler introduces new high-voltage P2 hybrid module; up to 800 N·m; first production application in China in 2017
September 29, 2015
Schaeffler has developed a new P2 (parallel, two-clutch) high-voltage hybrid module—arranged between the internal combustion engine and transmission—that can transmit engine torques of up to 800 N·m (590 lb-ft) to the transmission without having to incorporate a commensurately expensive clutch.The new generation P2 hybrid module can be used in both medium- and very high-performance transmission concepts—e.g., from mild to plug-in hybrids.
The high-torque module distributes the flow of forces in an innovative way; the pathway of torque conveyance depends on its direction. Torques are transmitted to the crankshaft via a 300 N·m disconnect clutch, while traction torques from the internal combustion engine are transmitted to the transmission via a one-way clutch. The clutch can therefore have a compact design, even at high torques, with the corresponding advantages in terms of space utilization and cost. Schaeffler showcased the unit at the International Motor Show (IAA) in Frankfurt.

The announcement came at the 20th Supercharging Conference in Dresden, Germany.
Eaton’s Twin Vortices Series (TVS) is a Roots-type supercharger with four- lobe rotors and high-flow inlet and outlet ports. TVS2 technology builds on Eaton’s supercharger portfolio by delivering significant improvements in efficiency and increased capability, achieved through a rotor design that improves the internal aerodynamics. Key elements of this new design include:
Audi’s e-tron quattro EV: evolutionary powertrain with a dash of revolution for production in 2018; MLB evo
September 24, 2015
Audi’s e-tron quattro battery-electric SUV concept, which made its formal debut at IAA in Frankfurt (earlier post), is a strong indicator of Audi’s series-production electric SUV due in 2018—especially in terms of the powertrain.
The e-tron quattro is based on Audi’s MLB evo—the second-generation of the modular longitudinal matrix toolkit (MLB, earlier post), and is, at the same time, potentially contributing to the development of the elements of that toolkit, especially with respect to a modular electric drive component. This could eventually have a role comparable to that of the Volkswagen Group’s modular diesel and modular gasoline engine kits (MDB and MOB). (“Baukasten” = German for construction kit)
Oak Ridge AMIE demo integrates 3D-printed building, natural gas hybrid with bi-directional wireless power transfer
A research demonstration unveiled at the Department of Energy’s Oak Ridge National Laboratory (DOE ORNL) combines clean energy technologies into a 3D-printed building and a 3D-printed natural gas-powered hybrid vehicle to showcase a new approach to energy use, storage and consumption. The Additive Manufacturing Integrated Energy (AMIE) demonstration, displayed at DOE’s Office of Energy Efficiency and Renewable Energy Industry Day event, is a model for energy-efficient systems that link buildings, vehicles and the grid.
An ORNL team worked with industrial partners to manufacture and connect a natural-gas-powered hybrid electric vehicle with a solar-powered building to create an integrated energy system. Power can flow in either direction between the vehicle and building through a lab-developed wireless technology. The approach allows the car to provide supplemental power to the 210-square-foot building when the sun is not shining.
New ORNL non-precious metal catalyst shows promise as low-cost component for low-temperature exhaust aftertreatment
September 23, 2015
Researchers at Oak Ridge National Laboratory (ORNL) have developed a ternary mixed oxide catalyst composed of copper oxide, cobalt oxide, and ceria (dubbed “CCC”) that outperforms synthesized and commercial platinum group metal (PGM) catalysts for CO oxidation in simulated exhaust streams while showing no signs of inhibition—i.e., the clogging of the catalyst by NOx, CO and HC.
PGM catalysts are the current standard for emissions aftertreatment in automotive exhaust streams. However, in addition to their high cost, PGM catalysts struggle with CO oxidation at low temperatures (<200 °C) due to inhibition by hydrocarbons in exhaust streams. The new ORNL catalyst shows great potential as a low-cost component for the low temperature exhaust streams that are expected to be a characteristic of future automotive systems, the researchers noted in their paper in the journal Angewandte Chemie.
NRC Canada team investigates effect of gasoline particulate filter on PM from light-duty GDI engine
September 17, 2015
A team led by researchers from the National Research Council Canada has investigated the effect of the use of a gasoline particulate filter on the size and morphology of PM emitted from a light-duty gasoline-direct-injection (GDI) vehicle over the FTP-75 and US06 transient drive cycles.
Using transmission-electron-microscope (TEM) image analysis, they compared PM from a 2012 Ford Focus powered by a 2.0-liter wall-guided GDI engine, operating under globally stoichiometric condition, to the results for the same vehicle equipped with a catalyzed gasoline particulate filter (GPF). A paper describing their results is published in the ACS journal Environmental Science & Technology.

General Motors is the first North American automotive OEM to integrate the Continental ultracapacitor-based voltage stabilization as part of the enhanced start-stop system, which lowers fuel costs, improves performance and reduces emissions, delivering an overall superior owner-driver experience.
There are currently some 1.5 million vehicles on the road in Europe with the Maxwell-based Continental VSS, said Marty Mills, regional sales manager, ultracapacitor products, Central North America.
Jaguar Land Rover investigating energy-efficient vehicle heating and cooling; Air Bubbles and Air Blankets
September 10, 2015
Because heating, ventilation and air conditioning systems (HVAC) consume substantial amounts of energy—and therefore fuel, or electrical energy stored in the battery of a Battery Electric Vehicle (BEV)—Jaguar Land Rover (JLR) is working on research projects that could significantly reduce the energy consumed when heating and cooling a vehicle.
Rather than continuously heating or cooling a flow of air as it enters the car, Jaguar Land Rover is exploring how a car could heat or cool an “Air Bubble” inside the vehicle once, and then maintain the temperature and quality of this air bubble using innovative new HVAC technologies. These include infra-red reflective (IRR) glass, tailor-made for the solar radiation profile of an individual region or country. The glass would reflect the sun’s rays so less energy is required to cool the inside of the car.
Jaguar Land Rover showcases MHEV, PHEV and BEV Concept_e demonstrators; electric Drive Module
September 09, 2015
At the CENEX Low Carbon Vehicle event in the UK, Jaguar Land Rover (JLR) is showcasing three Concept_e research demonstrators—a mild hybrid, plug-in hybrid, and battery-electric vehicle—including a new novel high performance, modular electric drive module (eDM) developed in-house by Jaguar Land Rover.
These are capable of producing twice the power and torque of any electric motor-generator currently in production, JLR said, and can be inserted between any engine and transmission to create MHEV or PHEV, or used alone for a BEV.
New Tandem Axle Lift function from Volvo Trucks lowers fuel consumption up to 4%
Volvo Trucks has introduced a new function—Tandem Axle Lift—that makes it possible to disengage and raise the second driven axle even while driving. This gives better road grip and up to 4% lower fuel consumption when the truck is driven without a load. The new function is designed for heavy duty transports with loads being carried one way and empty return trips—for example, when hauling timber or in construction and bulk cargo operations.
By replacing the differential in the first driven axle with a dog clutch, the second driven axle can be disengaged and raised; the tires can be lifted 140mm (5.51 inches) off the road surface. The driver thus has access to both the power and capacity of two driven axles (6X4) and also the better maneuverability of a single driven axle (4X2).
Bosch presenting new heat pump EV thermal management system at IAA; up to 25% increase in effective range
September 08, 2015
At IAA next week, automotive supplier Bosch is presenting a new heat-pump-based thermal management system for EVs that it says can enable an increase in effective range of up to 25% without modifications to the battery.
In battery-driven powertrains, heating and cooling can play a significantly greater role than in gasoline or diesel engines, since without a combustion engine, the vehicle does not have a generous supply of heat. If the passenger compartment is heated using a purely electrical system drawing its power from the battery, range can be significantly reduced. As a result, there has been interest in the industry about the use of heat pumps as a lower energy-intensity solution.
Peugeot FRACTAL electric concept adds acoustic spatialization to i-Cockpit; 3D printing
At the IAA in Frankfurt next week, Peugeot will introduce FRACTAL, a prospective electric urban coupé design that incorporates the company’s i-Cockpit (first unveiled in 2010) augmented with an acoustic system that features tactile bass systems built into the back of each seat to make driving all the more instinctive, enriching information through the use of acoustics. This additional i-Cockpit feature is characterized by the spatialization and dynamization of sound.
FRACTAL is an ideas incubator that also explores new design and manufacturing processes. 3D-printed parts represent more than 80% of the interior trim surface. The anechoic materials were made through generative design—an incremental, stochastic process used to achieve the perfect component.
Fraunhofer researchers develop carbon nanotube thin film heater for EVs
September 02, 2015
Researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart have developed a film-based panel heater for electric vehicles. The panel is—particularly on short journeys—more effective than conventional electric heaters. (Electric cars generate little heat as opposed to conventional passenger vehicles, which produce more than enough engine heat to heat the interior. An additional electric heater is required. This is supplied with power by the same battery that provides the engine with energy; prolonged use of the heater can significantly deplete range.)
The heating concept is based on a film that is coated with a very thin layer of conductive carbon nanotubes (CNTs). The film is glued to the inner door trim and generates a comfortable warmth there in the area of the armrest within a very short time, according to Serhat Sahakalkan, project manager at the Fraunhofer IPA.

It offers improved safety and security with a traffic class immune to Denial of Service. It also enables the full convergence of critical, real-time and regular traffic within a single network.
FEV working on water injection system using exhaust condensate; fuel consumption improvements up to 16% possible
August 26, 2015
FEV is developing a water injection system for internal combustion engines using condensate from exhaust gases, the “Extended Direct Condensate Injection” system. The concept, as reported in a new paper in the International Journal of Engine Research , demonstrates a potential for efficiency increase of 3.3% – 3.8% in the region of the minimum specific fuel consumption on a stoichiometric combustion concept with Miller cycle and cooled external exhaust gas recirculation.
Further improvement of the efficiency of up to 16% is possible at full-load operation, the researchers said. If water injection is used in addition to homogeneous lean combustion, an efficiency gain of 4.5% in the region of the minimum specific fuel consumption is achieved.
