CARB releases Midterm Review of ZEV regulation, LEV III GHG and PM standards; calls for post-2025 standards
January 19, 2017
When the California Air Resources Board (ARB) adopted the Advanced Clean Cars (ACC) program in 2012 (earlier post), the agency committed to conduct a comprehensive midterm review of three elements of the program: the zero-emission vehicle (ZEV) regulation; the 1 mg/mi particulate matter (PM) standard; and the light-duty vehicle greenhouse gas standards for 2022 and later model years. ARB has now released the Midterm Review of Advanced Clean Cars Program—an extensive evaluation of the California passenger vehicle market and technology.
The Review finds that the greenhouse gas (GHG) emission standards currently in place for model years 2022-2025 are readily feasible at or below the costs estimated back in 2012. The report also finds that ZEV technology has seen significant development that, in many cases, is beyond what was envisioned just four years ago. The report indicates that existing programs in California will add at least 1 million zero-emission vehicles on its roads and highways by 2025.

DOE Co-Optima initiative publishes report reviewing first 12 months; progress on fuels and engines
January 16, 2017
The US Department of Energy’s (DOE’s) Co-Optima initiative—a broad, joint effort to co-optimize the development of efficient engines and low greenhouse-gas fuels for on-road vehicles with the goal of reducing petroleum consumption by 30% by 2030 beyond what is already targeted (earlier post)—has published a year-in-review report for FY 2016—the initiative’s first 12 months.
Co-Optima’s premise is that current fuels constrain engine design—and thus engine efficiency. The researchers suggest that there are engine architectures that can provide higher thermodynamic efficiencies than available from modern internal combustion engines; however, new fuels are required to maximize efficiency and operability across a wide speed/load range. The report details the technical progress in a selection of projects across the initiative’s two main thrusts: spark ignition (SI) and advanced compression ignition (ACI).
U of Birmingham scientists launch project to tackle global clean cold challenge
Scientists from the University of Birmingham launched a major research project to investigate how “clean cold” could help to achieve almost all of the United Nations’ (UN) global Sustainable Development Goals. The 17 Global Goals include abolishing poverty and hunger; providing good healthcare and education; raising peoples’ quality of life; and cleaning up the environment, while promoting economic growth.
Clean cooling technologies, which can support environmentally sustainable cold chains, include Dearman’s zero-emission transport refrigeration system (earlier post); solar-driven cooling for pack-houses; and even small transportable ammonia-water absorption refrigeration which can be used to transport medicine.
Achates Power building 2.7L opposed-piston light-duty engine; exceeding CAFE 2025, Tier 3 targets at lower cost
January 13, 2017
Stemming from a major project partially funded with a $9-million grant from the Advanced Research Projects Agency - Energy (ARPA-E) to develop an opposed-piston two-stroke gasoline compression ignition engine (OPGCI) (earlier post), Achates Power announced it is developing a 2.7-liter, 3-cylinder (i.e., six-piston) light-duty version of its opposed piston engine (OPE) in both diesel- and gasoline-fueled versions. Achates will demonstrate the engine in 2018 in a driveable light-duty truck.
The 2.7-liter compression-ignition OPE will will be 30-50% more fuel efficient than comparable diesel and gasoline direct injection engines, reduce emissions and cost less than alternative technologies under development for meeting 2025 CAFE fuel economy and Tier 3 emission targets.
ICCT: New RDE regulations not enough to control diesel car NOx fully; additional actions required
Real-world NOx emissions from new diesel cars could still exceed the Euro 6 emission limit of 80 mg/km by a factor of three or more, even after the new Real-Driving Emissions (RDE) regulation takes effect, according to a new white paper released by the International Council on Clean Transportation (ICCT). However, taking specific actions beyond those mandated in the regulation—such as introducing spot checks for randomly selected vehicles and expanding the range of driving conditions covered by RDE testing—could reduce new diesel car NOx emissions to 96 mg/km—just 1.2 times the Euro 6 limit—by 2022.
For the study, the team analyzed an extensive set of diesel car emissions data using modeling of the boundary conditions of the RDE regulation. The researchers also examined the impact of ICCT’s proposed modifications.
Oberon Fuels, Mack Trucks, and New York City Department of Sanitation begin first customer demonstration of a DME-powered Mack Truck
January 12, 2017
Oberon Fuels, a producer of clean-burning Dimethyl Ether (DME) transportation fuel (earlier post), announced the first customer demonstration of a DME-powered Mack truck, a Mack Pinnacle. Oberon and Mack are working with the NYC Department of Sanitation (DSNY) to run the vehicle at the Fresh Kills Landfill and evaluate performance and overall drivability. The test is the first step in the city’s evaluation of both DME trucks and DME fuel as a potential long-term strategy to help reduce greenhouse gas emissions by 80% by 2050 and to achieve the city’s goal of sending zero waste to landfill by 2030.
The goal of the demonstration is to gather data on the use of DME fuel and vehicles in urban, heavy-load fleets. At scale, such a program could convert hundreds of thousands of tons of organic waste into clean fuel, reducing emissions, waste, and costs for cities while improving overall air quality and creating jobs.
EPA and CARB charge Fiat-Chrysler with using undeclared emission control devices in 3.0L diesels
The US Environmental Protection Agency (EPA) issued a notice of violation (NOV) to Fiat Chrysler Automobiles N.V. and FCA US LLC (collectively FCA) for alleged violations of the Clean Air Act for installing and failing to disclose at least eight auxiliary emissions control devices (AECDs) in light-duty model year 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines sold in the United States. The undisclosed engine management software results in increased emissions of nitrogen oxides (NOx) from the vehicles, the agencies said. The allegations cover roughly 104,000 vehicles.
EPA is working in coordination with the California Air Resources Board (CARB), which has also issued a notice of violation to FCA. There are about 14,000 of the affected vehicles on the road in California. EPA and CARB have both initiated investigations based on FCA’s alleged actions.
Renault Trucks working with metal 3D printing to reduce engine size and weight
The Renault Trucks Lyon Powertrain Engineering department is developing metal additive manufacturing—i.e., 3D metal printing—as a future engine manufacturing process. The aim of this project is to demonstrate the positive impact of metal additive manufacturing on the size and weight of an engine, said Damien Lemasson, project manager at Renault Trucks.
Renault has designed a prototype DTI 5 4-cylinder Euro 6 step C engine for 3D printing production; the ability of additive manufacturing to produce complex forms resulted in a 25% reduction in the number of components in the DTI 5 engine—a total of 200 fewer parts. The Renault engineers have also manufactured rocker arms and camshaft bearing caps by metal 3D printing and successfully bench-tested these for 600 hours inside a Euro 6 engine.

EPA and CARB approve emissions modification for Gen 3 VW 2.0 liter diesel vehicles
January 06, 2017
The US Environmental Protection Agency (EPA) and California Air Resources Board (CARB) approveda remedy proposed by Volkswagen that will reduce the excess NOx emissions from the Generation 3 (MY 2015) diesel 2.0 liter vehicles. With the approval, VW can offer vehicle owners the choice to keep and fix their car, or to have it bought back.
This modification will reduce excess emissions from the affected vehicles by 80-90%. The test data and technical information VW submitted to EPA and CARB demonstrated that the emissions modification being approved will not affect vehicle fuel economy, reliability, or durability. EPA and CARB confirmed those conclusions through independent testing and analysis at their own laboratories.
ICCT: real-world NOx from Euro 6 diesel passenger cars more than 2x Euro VI diesel trucks
In Europe, the average amount of NOx present in exhaust emissions from modern diesel passenger cars under real-world conditions is more than double the levels from modern trucks and buses, according to a new briefing paper released by the independent research organization International Council on Clean Transportation (ICCT).
The ICCT paper shows data for 24 Euro VI buses and trucks, some tested on a chassis dynamometer by the Technical Research Centre of Finland (VTT), and others tested on-road using portable emissions testing equipment by the German type-approval agency KBA. On average, NOx emissions of the heavy-duty vehicles tested were approximately 210 mg/km. Currently, NOx emissions of Euro 6 diesel passenger cars under real-world driving conditions are approximately 500 mg/km, as determined by testing carried out by KBA and other European type-approval agencies. In addition, the average conformity factor—the ratio of the test result to the regulatory limit—for the heavy-duty engines was less than 1, meaning that on-road emissions stayed below the Euro VI engine type-approval test limits.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges
December 09, 2016
Honeywell’s Transportation Systems Forecast projects that turbocharged vehicles will acount for 48% of annual global sales by 2021, up 9 percentage points from 2016. This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today.
This year’s forecast recognizes an industry trend for slightly bigger engine sizes in Europe and China as automakers adapt powertrain strategies to tackle updated emissions regulations developed for real-world driving conditions. In these regions, a typical powertrain is a three- or four-cylinder engine with a displacement size between 1.2 liters and 1.7 liters. By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance.

New ORNL hardware-in-the-loop capability to integrate advanced combustion, new fuels, and electrification pathways
December 02, 2016
A multi-disciplinary team of researchers at Oak Ridge National Laboratory (ORNL) has developed a new testing capability which integrates a driver model, full vehicle model, and hardware to explore the synergies of advanced combustion, new fuels, and emerging hybrid vehicle architectures over real-world drive cycles. This new facility is focused on low temperature combustion engines but builds upon the powertrain-in-the-loop expertise established with the Vehicle Systems Integration Laboratory (VSI) at ORNL.
The transient advanced combustion laboratory is initially supporting research on the potential of low temperature combustion modes with new fuel and vehicle technologies. The hardware-in-the-loop setup includes a transient dynamometer cell (AVL 300 kW AC) with a low-temperature combustion (LTC) multi-cylinder engine instrumented for combustion and emissions analysis. The light-duty diesel engine used in these experiments (earlier post) was modified for dual-fuel use for port fuel injection of low-reactivity fuel (i.e. gasoline, ethanol etc.) and a high-reactivity fuel (i.e. diesel, biodiesel etc.).
Eco-Motive reveals prototype H-Motor dual fuel engine; road testing to begin soon
Eco-Motive, a startup developing what it calls the first dual-fuel “H” engine (earlier post), revealed photos of a full-scale prototype of the Eco-Motive H-Motor. The prototype was completed in February 2016 and was built to reflect the engine configuration when installed in a vehicle; testing in driving applications will begin soon.
The H-shaped engine has parallel left-side and right-side vertical inline piston banks, each with a crankshaft and pistons, cylinder head, and individual fuel feeds, but sharing a common power transmission system. The H-motor—essentially two separate engines housed within the same engine block—can be powered by either gasoline or compressed natural gas (CNG), at the driver’s decision.
Ford to offer cylinder deactivation for 1.0L EcoBoost in 2018; 6% fuel economy boost; global first for a 3-cylinder
November 30, 2016

ICCT: 2025 target average of 70 g/km CO2 for new cars in EU feasible and economical; more so with electric drive
A 2025 CO2 target of an average 70 g/km for new cars in the EU could be met with very little electrification and with an average payback period of less than 4 years, according to a new study by the International Council on Clean Transportation (ICCT). However, transitioning soon to electric drive could lower manufacturers’ compliance costs by as much as €500 (US$532) per vehicle in 2025.
Under current European Union regulations, average new car CO2 emissions must decrease from the present 120 grams per kilometer (g/km) to 95 g/km by 2021. Although no further reductions are presently mandated, new targets for 2025 and 2030 are under discussion in Brussels. In 2013 the European Parliament recommended an “indicative range” of 68–78 g/km for 2025, while holding out the possibility that even lower targets should be considered if justified.
Big Blue Bus receives nearly $900K to purchase 58 new Cummins-Westport Near-Zero NOx engines

Shipping company Maersk Line and the ports of Los Angeles and Long Beach are partnering to measure the environmental benefits of a $125-million upgrade for 12 Maersk container ships. This will involve the installation of high-tech equipment to track vessel emissions and energy efficiency over the next three years, enabling more transparency and ultimately reducing the environmental impact of vessels calling at the San Pedro Bay port complex.
The two ports are contributing a combined $1 million to real-time tracking systems that represent an industry leading application to pinpoint vessel emissions while ships are at sea and at berth. Unprecedented in its scope and scale, the three-year data collection and analysis project, called “The Connected Vessel Programme”, builds on the $125 million Maersk Line has invested in its “radical retrofit” program to reduce fuel consumption and increase the capacity of the vessels that regularly call at the San Pedro Bay ports.
Argonne study on optimizing gasoline compression ignition at idle and low loads
November 09, 2016
Gasoline compression ignition—i.e., igniting gasoline purely by compression, as with a diesel, rather by using a spark—is a promising, high-efficiency, low-temperature combustion mode that offers low engine-out NOx and soot. (Earlier post.) GCI, however, is challenged by stable idle- to low-load operation (i.e., 0-2 bar BMEP) because it is challenging to ignite the low-reactivity gasoline purely through compression.
One way to address that challenge is through optimizing the injection system and injection strategy to ensure that the air-fuel mixture maintains a high level of reactivity. A team from Argonne National Laboratory now reports in a paper published in the International Journal of Engine Research on the effects of injector nozzle inclusion angle, injection pressure, boost, and swirl ratio on gasoline compression ignition combustion.

Ricardo’s “deep” Miller cycle concept: Magma
November 01, 2016
In its new report on downsized and boosted gasoline engine technologies (earlier post) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine.
The basic architecture of “Magma” concept is a boosted four-stroke gasoline engine with four valves per cylinder. The Magma concept architecture closes the inlet valve early to reduce pumping losses. A mechanical supercharger and fixed-geometry turbocharger fill cylinders effectively. A long exhaust stroke then extracts maximum efficiency.

Study finds ethanol blending appears to reduce significantly genotoxic emissions from gasoline direct injection vehicles
October 24, 2016
A research team from Empa (Swiss Federal Laboratories for Materials Science and Technology) and the University of Applied Sciences Bern, Laboratory for Exhaust Emission Control, reports that ethanol blending appeared to reduce genotoxic emissions from a flex-fuel Euro-5 gasoline direct injection (GDI) vehicle (a Volvo V60 with a 1.6 L engine) under transient and steady driving conditions.
In a paper published in the ACS journal Environmental Science & Technology, the researchers reported that particle number emissions when operating the vehicle in the hWLTC (hot started worldwide harmonized light-duty vehicle test cycle) with E10 and E85 were lowered by 97% and 96% respectively compared with that of E0. CO emissions dropped by 81% and 87%, while CO2 emissions were reduced by 13 and 17%. Emissions of selected polycyclic aromatic hydrocarbons (PAHs) were lowered by 67–96% with E10 and by 82–96% with E85, and the genotoxic potentials dropped by 72% and 83%, respectively.
ICL study of 39 new Euro-6 diesels finds huge variability in NOx emissions with an average 4.5x the type approval limit
October 21, 2016
A new study by researchers from Imperial College London(ICL) of 39 new Euro 6 diesel passenger cars has found “huge variability” in the on-road NOx emissions of Euro 6 diesel passenger cars, with results ranging from 1 to 22 times the type approval limit. All but 2 exhibited higher NOx than the limit.
The average NOx emission from the test cars of 0.36 g km-1 equates to 4.5 times the type approval limit; this rose to 5.4 times for urban driving. They attributed the increase in urban cycle NOx emissions in part to more frequent acceleration events. (Urban driving emissions could be reduced by more effective management of traffic flows (e.g., earlier post), easing of congestion and promotion of eco-driving, though further work is required to confirm this, they suggested.)

Cal Energy Commission approves $1M grant to develop 12L near-zero NOx nat gas engine
The California Energy Commission approved a $1-million grant to develop a 12-liter natural gas engine that produces near-zero nitrogen oxide (NOx) tailpipe emissions. The engines would be suitable for heavy-duty vehicles. The South Coast Air Quality Management District (SCAQMD) will work with Cummins Westport, Inc., to develop the engine. Cummins has a history of developing natural gas engines for heavy-duty application, and its engines are being used globally in a variety of commercial vehicles.
The California Air Resources Board (CARB) 2010 emission standards for heavy-duty engines establish a limit for NOx emissions of 0.2 grams per brake horsepower hour (g/bhp-hr), and constitute a 90% reduction of emissions compared to the previous standard (CARB 2007) of 2.0 g/bhp-hr. Nevertheless, it is projected that even with the entire on-road fleet of heavy-duty vehicles compliant with the 2010 standards, upcoming National Ambient Air Quality Standards requirements for ozone attainment cannot be achieved in California’s worst air basins without further significant reductions in NOx emissions from heavy-duty fleets.

Researchers find magnetite nanoparticles similar to those from traffic pollution in brain; possible link with Alzheimer’s
September 06, 2016
Researchers from the UK, Mexico and the US have found abundant magnetite nanoparticles in the brain tissue from 37 individuals aged three- to 92-years-old who lived in Mexico City and Manchester, UK. This strongly magnetic mineral has been implicated in the production of reactive oxygen species (free radicals) in the human brain, which are associated with neurodegenerative diseases including Alzheimer’s disease (e.g., Hautot et al. 2003). Their paper is being published in Proceedings of the National Academy of Sciences (PNAS).
Professor Barbara Maher, from Lancaster Environment Centre, and colleagues (from Oxford, Glasgow, Manchester and Mexico City) used spectroscopic analysis to identify the particles as magnetite. Unlike angular magnetite particles that are believed to form naturally within the brain (i.e., biogenic), most of the observed particles were spherical, with diameters up to 150 nm, some with fused surfaces, all characteristic of high-temperature formation—such as from vehicle (particularly diesel) engines or open fires.

Cummins and Peterbilt to team up on SuperTruck II
September 01, 2016
For SuperTruck II, the Cummins–Peterbilt team will focus on breakthrough advances in Class 8 vehicle freight efficiency technologies that are cost-effective enough to be used in everyday real-world applications. Building on the solid foundation of SuperTruck I, Cummins will develop and demonstrate 55% or greater engine Brake Thermal Efficiency (BTE) at a 65 mph cruise condition and the full team will demonstrate a greater than 100% improvement in vehicle Freight-Ton Economy (FTE) over the 2009 baseline vehicle.
Bosch more broadly commercializing water injection system; up to 13% fuel savings under some conditions
Bosch is now more broadly commercializing its water injection system for turbocharged engines (earlier post). Bosch currently supplies water injection parts for the BMW M4 GTS—the first production vehicle to feature a water injection system. (Earlier post.) In the vehicle’s turbocharged six-cylinder engine, it offers improved performance and consumption even at full load.
Bosch’s WI system comprises a water pump; a water rail; and injectors which have been designed to handle the specific challenges arising as a result of operation with water. Particularly when accelerating quickly or driving on the freeway, the injection of additional water makes it possible to reduce fuel consumption by as much as 13% in highway conditions and 4% in normal driving (WLTC).
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.
New Flyer adds 2016 Cummins Westport ISL G Near Zero engine to Xcelsior bus lineup; debuting in LA
August 18, 2016
Flyer of America Inc., a subsidiary of New Flyer Industries Inc., the largest heavy-duty transit bus and motor coach manufacturer and parts distributor in North America, is adding the 2016 Cummins Westport ISL G Near Zero engine (earlier post) to its Xcelsior bus family. New Flyer is the first transit manufacturer to offer the industry’s cleanest certified engine and will deliver the first original OEM installation of a the engine in the third quarter of 2016.
The ISL G NZ compressed natural gas is certified by both US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California to meet the 0.02 g/bhp-hr optional Near Zero NOx Emissions standards for medium-duty truck, urban bus, school bus and refuse applications. The engine will be used to power a New Flyer Xcelsior XN40 bus for the Los Angeles County Metropolitan Transportation Authority (LA Metro). LA Metro operates the largest natural gas engine transit vehicle fleet in North America.
2017 Audi A4 ultra with Millerized 2.0 TFSI offers 31 mpg combined; highest EPA-estimated fuel economy in competitive segment
August 17, 2016
Audi’s 2017 A4 ultra leverages the Millerized 2.0-liter TFSI engine (earlier post) to achieve 27 mpg (8.7 l/100 km) city, 37 mpg (6.35 l/100 km) highway, and 31 mpg (7.58 l/100 km) combined EPA-estimated fuel economy. No other luxury sedan in its non-hybrid competitive segment offers higher EPA-estimated city or highway mileage.
The efficiency of the 2.0 TFSI is the result of Audi’s Millerized combustion method with shorter compression and longer expansion phases as well as increased compression. The Miller cycle uses a higher expansion ratio than compression ratio (i.e., over-expansion) obtained by either early or late closing of the intake valves (EIVC and LIVC, respectively), and results in a smaller effective compression stroke; combustion and expansion proceed normally.
2017 Range Rover Sport gains new Ingenium 2.0L diesel as option; semi-autonomous driving tech
For the 2017 Model Year, Range Rover Sport will debut the new 2.0-liter four-cylinder Ingenium diesel engine (earlier post), manufactured at Jaguar Land Rover’s own engine plant in Wolverhampton, UK. Already available on both Discovery Sport and Range Rover Evoque models, Ingenium is Jaguar Land Rover’s new breed of engine designed for performance, refinement and efficiency.
The 2017 Model Year Range Rover Sport is the first full-sized Land Rover SUV to feature a four-cylinder diesel engine. The all-aluminium 2.0-liter SD4 Ingenium produces 240 hp and 500 N·m (369 lb-ft) of torque, and is capable of returning (38 mpg US, 6.2 l/100 km) on the EU combined cycle with emissions of 164 g/km (manufacturer’s estimated data).

August 16, 2016
The US Department of Energy (DOE) will invest up to $137 million in two programs, subject to appropriations, to develop next-generation technologies that will support industry in going beyond the newly announced Phase II standard for medium- and heavy-duty vehicles (earlier post) and also accelerating technology advances for passenger cars and light trucks.
One initiative, SuperTruck II (earlier post), will award $80 million to four projects to develop and to demonstrate cost-effective technologies that more than double the freight efficiency of Class 8 trucks. Through the other initiative, the Office of Energy Efficiency and Renewable Energy Vehicle Technologies Office Program Wide Funding Opportunity Announcement (earlier post)selections, 35 new projects will receive $57 million to develop and deploy a wide array of cutting-edge vehicle technologies, including advanced batteries and electric drive systems, to reduce carbon emissions and petroleum consumption in passenger cars and light trucks.
Infiniti introducing production-ready variable compression ratio engine at Paris Motor Show
August 15, 2016
Infiniti will introduce a production-ready variable compression ratio engine VC-T (Variable Compression-Turbocharged) at the 2016 Paris Motor Show (Mondial de l’Automobile) in September. Infiniti said that the new four-cylinder turbocharged gasoline VC-T engine has been in development for more than 20 years. (Nissan was awarded a patent in 1995 on compression ratio control for an engine.)
Interest in variable compression engines stretches back more than 40 years. In a 1976 SAE paper, Grundy et al. described the Teledyne Continental Motors (TCM) AVCR 1360-2 variable compression ratio (VCR) diesel engine, the culmination of fifteen years of VCR piston and high specific output research. Two main types of variable compression ratio systems have been proposed over the years: continuous and two-stage.

The KBA approval applies to 460,000 vehicles of affected Group brands, including the Volkswagen Polo and SEAT Ibiza models.
The software update can now be promptly carried out on the first vehicles of the second affected engine-size category. The owners of these models are being successively informed and can then make an early appointment with an authorised workshop to have the update done.
CALSTART brief highlights growth of and future opportunity for California’s clean transportation technology industry
August 08, 2016
A new CALSTART brief indicates that California’s climate and energy policies are not only helping to protect the environment and improve air quality, but are also helping to accelerate growth of the clean transportation technology industry (CTTI) in the state.
The paper, “California’s Clean Transportation Technology Industry: Time to Shift into High Gear,” profiles the development of a burgeoning manufacturing sector that is producing zero- and near-zero emission light-, medium- and heavy-duty vehicles, as well as clean fuels, engines, vehicle components, and new mobility services.
Argonne team discovers self-regenerating DLC tribofilm
August 05, 2016
Researchers at Argonne National Laboratory have discovered an ultra-durable, self-lubricating tribofilm that regenerates in the presence of oil, heat, and pressure—meaning that it will not wear away over the life of an engine. The film, reported yesterday in the journal Nature, develops when a new catalytic coating that can be applied to engine parts interacts with lubricating oil to create an extremely tough coating that almost eliminates wear.
Tests revealed the diamond-like carbon (DLC) tribofilm reduced friction by 25-40% and that wear was reduced to unmeasurable values. The discovery could have implications for the efficiency and durability of future engines and other moving metal parts that can be made to develop self-healing DLC tribofilms.
ORNL team further characterizes PM from RCCI combustion; possible different PM formation process than conventional diesel
August 04, 2016
Researchers at Oak Ridge National Laboratory (ORNL) have been working for years to advance reactivity-controlled compression ignition (RCCI) technology (e.g., earlier post, earlier post). The work includes not only advancing the combustion technology itself, but also characterizing and analyzing the emissions from RCCI (earlier post).
In a new open-access paper published in the International Journal of Engine Research, the Oak Ridge team summarizes its research to date on characterizing the nature, chemistry and aftertreatment considerations of RCCI particulate matter (PM) and presents new research highlighting the importance of injection strategy and reactive and unreactive fuel compositions on RCCI PM formation.
Ford’s new Dagenham Diesel EcoBlue engine production line reduces energy and water use by more than 50%
The new Ford EcoBlue diesel engine production line at Dagenham Engine Plant will reduce water and energy consumption by more than 50%. Dagenham Engine Plant is Ford’s largest diesel engine production facility globally, and produced the first EcoBlue diesel engine (earlier post) in April this year. Water usage per engine will be among the lowest at any Ford manufacturing facility worldwide, delivering an anticipated annual saving of 17.5 million liters of water compared with 2011—enough to fill seven Olympic-size swimming pools.
The reduction in the volume of coolant pumped around the facility also helps to significantly reduce energy usage. Three smaller coolant systems require around 70% less energy, and contribute to reducing energy use per engine from 188 kWh in 2011 to 92 kWh in 2016—the energy saved is roughly enough to power an average house for a week.
Federal-Mogul Powertrain develops upgraded coating for heavy-duty piston rings
August 03, 2016
Federal-Mogul Powertrain has developed an upgrade to its GOETZE Diamond Coating (GDC) for piston rings, a technology that has been meeting heavy-duty diesel engine requirements for more than a decade. The new coating, GDC60, features higher diamond content than the established GDC50 to further reduce wear and has demonstrated lower friction and greater scuff resistance during testing.
The upgraded coating will be shown this September alongside other Federal-Mogul heavy-duty technologies at IAA Commercial Vehicles in Hanover.
DOE to award $7M to accelerate fuel and engine co-optimization technologies; Co-Optima initiative
August 01, 2016
The US Department of Energy (DOE) will award up to $7 million in project funding to accelerate the introduction of affordable, scalable, and sustainable high-performance fuels for use in high-efficiency, low-emission engines as part of the Co-Optimization of Fuels and Engines (Co-Optima) initiative. (Earlier post.)
Co-optimized fuels and engines offer the opportunity to build on decades of advancements in both fuels and engines. Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. The new funding opportunity (DE-FOA-0001461) will advance the long-term objective of the Co-Optima initiative to accelerate widespread deployment of significantly improved fuels and vehicles (from passenger to light truck to heavy-duty commercial vehicles) by 2030.
Penn State, U Mich team characterizes soot generated by low-temperature diesel combustion
July 29, 2016
Researchers from Penn State and the University of Michigan have characterized the nanostructure and oxidative reactivity of soot generated by a light-duty turbodiesel engine operating under a dilute, low-temperature combustion process referred to as high-efficiency clean combustion (HECC). Their paper appears in the International Journal of Engine Research.
Earlier work by members of the team (Gregory Lilik and André Boehman) had shown that high cetane number fuel with HECC leads to reductions in all primary pollutant emissions—i.e., THC and CO as well as NOx and PM. (Earlier post.) Less established, however, is how well such dilute combustion processes influence soot formation.
