A rigorous emissions testing of modern heavy-duty diesel engines in the US has demonstrated a greater than 94% reduction in the levels of nitrogen dioxide (NO2 - an important contributor to ozone smog), and substantial reductions in all other pollutants, even when compared to engines first marketed to meet 2007 standards, according to a study released today by the Coordinating Research Council (CRC).
For a number of the most important pollutants, levels were substantially lower than required by regulations. The study, the Phase 2 Report of the comprehensive Advanced Collaborative Emissions Study (ACES) (earlier post), found that emissions of NO2 and other nitrogen oxides—which can have direct health effects and contribute to the formation of smog—were approximately 61% below the 2010 EPA standard and 99% lower than in 2004 engines. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

Study finds biodiesel use in HD trucks in Canada will result in very minimal changes in air quality and health benefits
November 07, 2013
Results of a study by a team from Health Canada and Environment Canada suggest that the use of B5 and B20 biodiesel fuel blends (5% and 20% biodiesel, respectively) compared to ULSD in on-road heavy-duty diesels in Canada will result in very minimal changes in air quality and health benefits/costs across Canada, and that these were likely to diminish over time.
Health Canada is the Canadian Federal department responsible for helping Canadians maintain and improve their health; Environment Canada is the Federal agency tasked with, among other things, protecting the environment. An open-access paper on the study has been accepted for publication in the ACS journal Environmental Science & Technology.

New valveless electro-hydraulic steering system for off-road equipment shows significant fuel savings and productivity benefits
September 25, 2013
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.

|BRUSA 750V electric drive components. Click to enlarge.|
BRUSA Elektronik AG is now offering its proven electric-drive components—including motor, controller, power electronics, battery pack and chargers—in 750-volt versions. The new 750-volt products are suited for use in commercial vehicles and applications demanding very high output performance.
Increasing the voltage reduces the current with the performance remaining the same. Lower current leads to a reduction of cable thicknesses and bending radii. This will directly result in weight and material savings—especially with commercial vehicles of a certain length such as trucks or buses, BRUSA says.
ARB researchers evaluate in-use heavy-duty NOx aftertreatment systems, find elevated levels during certain lower-temperature operations
July 09, 2013
A team from the California Air Resources Board (ARB) reports on their evaluation of the in-use emissions performance of four different heavy-duty diesel engines certified to the MY 2010 or interim MY 2010 NOx standards over a wide range of driving conditions in California in a paper published in the ACS journal Environmental Science & Technology.
One of the trucks was equipped with exhaust gas recirculation (EGR); three were equipped with EGR and a selective catalytic reduction (SCR) device. The results indicated that brake-specific NOx emissions for the truck equipped only with an EGR were independent of the driving conditions—and exceeded the certification value over each segment of the entire test route. Results also showed that for typical highway driving conditions, the SCR technology is proving to be effective in controlling NOx emissions. However, they also found that under operations where the SCR systems do not reach minimum operating temperature—e.g., cold starts and some low-load/slow-speed driving conditions—NOx emissions are still elevated.

|Meeting long-term CO2 targets for buses will require the development of advanced technologies, in parallel with improvements to engines. Source: Ricardo. Click to enlarge.|
A wide range of technologies can cut carbon emissions from buses and provide a short-term payback at current fuel prices and subsidy levels, according to a new report prepared for the UK’s Low Carbon Vehicle Partnership (LowCVP) by Ricardo. Overall, the study indicates that significant improvements in bus CO2 can be achieved in the medium to long term through development, incentivization (or regulation) and implementation of new vehicle technologies and fuels.
The aim of the LowCVP study was to identify a range of low carbon fuels and technologies which can cost-effectively reduce well-to-wheel (WTW) CO2 emissions for urban buses in the UK. The report developed technology roadmaps to illustrate when these technologies are likely to be ready for deployment into the bus market, focusing on the timescales 2012-2020 and 2020-2050. The study also examined the wider role of the selected fuels and technologies for decarbonizing heavy goods vehicles.

Volvo Trucks to begin limited production of DME heavy-duty trucks in NA in 2015; customer trials; Oberon partnership
June 07, 2013
|Volvo VNL D13 with DME. Click to enlarge.|
At an event in Sacramento, California, Volvo Trucks announced that it will commercialize dimethyl ether (DME)-powered heavy-duty commercial vehicles in North America, with limited production beginning in 2015. Volvo also revealed ongoing customer field testing of DME trucks in the US (with Safeway and Martin Transportation), as well as its partnership in the customer trials with startup DME producer Oberon Fuels. Oberon Fuels is the first company to announce plans to commercialize DME fuel production in North America. (Earlier post.)
DME offers diesel-quality performance with a high cetane number and low auto-ignition temperature, but burns cleanly without producing any soot. It is non-toxic, non-carcinogenic, and can be made from a variety of sustainable domestic sources, as well as from North America’s abundant supply of natural gas. The carbon intensity of the DME will vary with the feedstock, but with the use of bio-gas (biomethane) from an anaerobic digester as input into the Oberon process, DME can provide up to a 95% CO2 reduction compared to diesel. Volvo has been testing Bio-DME in Sweden since 2009. (Earlier post.)

|Close-up of the charging mechanism on the demo TOSA bus. Source: ABB. Click to enlarge.|
ABB has developed and is demonstrating a high-capacity “flash charging” system for electric buses. The system enables onboard batteries to be charged in 15 seconds with a 400 kW boost at selected stops using a roof-mounted system (“Flash station”). The flash stations are connected to the 50kVA electricity network and also have a 3kWh storage unit (supercap) for smoothing peaks in consumption.
At the end of the bus line (“Terminus station”) a 3 to 4 minute boost at 200 kW tops up the batteries. At the depot station, the bus plugs into a multi-bus supply station connected to the 50 kVA network.
CALSTART to evaluate Navitas Systems’ military-grade Li-ion 6T batteries in Class 8 highway trucks
May 22, 2013
Navitas Systems LLC, which earlier this year acquired substantially all of the assets of bankrupt A123 Systems’ former Ann Arbor, Michigan-based government business, including US military contracts, has signed a contract to supply prototypes of its upcoming 6T lithium-ion battery (earlier post) for use by CALSTART in assessing the efficacy of this advanced battery in hot and cold weather testing on Class 8 highway trucks.
The 6T battery is commonly used in military vehicles, and to-date has been based on lead-acid chemistry. The Navitas 6T prototype batteries embody the same physical form factor, but utilize advanced lithium iron phosphate chemistry, offering greater cycle and calendar life, discharge runtime, charge acceptance rate and amp-hour throughput over life, all at half the weight of lead acid.
ACEEE report recommends steps toward international alignment of heavy-duty vehicle efficiency standards
April 05, 2013
A new report published by the American Council for an Energy-Efficient Economy (ACEEE) recommends the international harmonization of fuel efficiency and/or greenhouse gas emissions standards for heavy-duty trucks and buses.
Foundational steps toward such alignment would include a common set of test cycles and test payload weights, which would serve to define universal measures of vehicle performance. This in turn would permit a standardized calculation of cost-effectiveness of technology improvements as a function of regional conditions. This would also allow comparison of vehicles in a range of driving conditions, and in particular would allow buyers to estimate performance over their own duty cycles, the report suggests.
Study suggests operational optimization can maximize the health and climate benefits of public transit investments in new bus technologies
April 02, 2013
A study by a team from the University of British Columbia and Metro Vancouver suggests that optimized operational control strategies for transit bus fleets ultimately offer transit agencies a way to maximize the benefits of their capital investments in new, cleaner technologies.
In their paper published in the ACS journal Environmental Science & Technology, they note that the evolution in bus technologies, particularly with respect to controlling pollutants that impact health—such as PM—combined with capital investments by transit agencies in these technologies, have resulted in the potential for large differences in emission factors within transit bus fleets. Operational optimization strategies such as vehicle assignment and scheduling can exploit this heterogeneous mix and minimize the climate and health impacts as well as operating costs of transit systems with minimal capital expenditure, they suggest.
CaFCP proposes two Centers of Excellence in California for fuel cell buses to accelerate commercialization; $100M program
March 30, 2013
The California Fuel Cell Partnership (CaFCP) has published “A Road Map for Fuel Cell Electric Buses in California: A zero-emission solution for public transit”. The roadmap suggests the steps necessary to move from the pre-commercial phase of fuel cell electric bus (FCEB) deployment and manufacturing (2012-2015) to the early commercial phase (2016- 2017) to a commercial model in 2018 and beyond, including the requisite fueling infrastructure.
This road map suggests a specific strategy for the implementation of two Centers of Excellence in Northern and Southern California, each of which would cost approximately $50 million and would operate 40 FCEBs. The two centers would allow for economies of scale sufficient to achieve 2016 DOE/DOT targets and begin to overcome the primary barriers to market: the capital cost of the vehicles and the cost of fuel, CaFCP suggests.

Diesel will surpass gasoline as the number one transportation fuel worldwide by 2020 and continue to increase its share through 2040, according to ExxonMobil’s recently published Outlook For Energy: A View To 2040. The relative shift away from motor gasoline to diesel is driven by improving light-duty vehicle fuel economy and the growth in commercial transportation activity. Diesel demand accounts for 70% of the growth in demand for all transportation fuels through the forecast period to 2040.
Fuel demand for heavy-duty vehicles, the largest subsector, sees the greatest growth, up 65%, and accounts for 40% of all transportation demand by 2040. About 80% of the growth in commercial transport demand will come from developing nations, according to the forecast. Fuel for aviation and marine will increase about 75% and 90%, respectively, over the Outlook period, with their combined share growing from about 20% today to more than 25% by 2040.

Shell and its affiliates will build two additional small-scale natural gas liquefaction units to provide liquefied natural gas (LNG) fuel for marine and heavy-duty on-road customers in North America. Pending final regulatory permitting, these two new liquefaction units are expected to begin operations and production in about three years.
These two units will form the basis of two new LNG transport corridors in the Great Lakes and Gulf Coast regions. This decision follows an investment decision in 2011 on a similar corridor in Alberta, Canada. (Earlier post.) Shell is also working to use natural gas as a fuel in its own operations.
Axion Power and ePower Engine Systems enter 5-year agreement for use of PbC batteries in diesel-electric drivetrains for Class 8 trucks; tests suggest up to 35% improvement in fuel economy
March 04, 2013
Axion Power International, Inc, the developer of advanced lead-carbon PbC batteries and energy storage systems (earlier post), has entered a strategic relationship with ePower Engine Systems LLC. ePower Engine Systems specializes in the retrofit and conversion of diesel-powered Class 8 trucks into series hybrid-powered units inspired by the diesel-electric drives in locomotives—i.e., the diesel engine powers a generator that in turn provides power directly to the traction motors.
ePower Engine Systems has consented to a five-year initial term with Axion Power that includes the exclusive use of Axion’s PbC batteries, and battery management systems in all ePower retrofits and conversions.
EEA report suggests road charges for heavy-duty goods vehicles should reflect varied health effects of pollution in different countries

A new report from the European Environment Agency (EEA) suggests that new road charges for heavy goods vehicles (HGVs or lorries) should reflect the varied health effects of traffic pollution in different European countries. This means charges should be much higher in some countries compared to others, according to the (EEA).
The amended Eurovignette Directive (2011/76/EU) relating to the charging of HGVs for use of major European motorways prescribes that from 2013, Member States may include air pollution costs in any charging structure for roads under the Trans‐European Network (TEN-T) and for comparable domestic motorways. The revenue from such schemes should be invested in sustainable transport, the Directive states. However, adoption of road user charges depends on a decision by individual countries.
California ARB to hold public workshop on new GHG and emissions standards for heavy-duty engines and vehicles
February 21, 2013
The California Air Resources Board (ARB) will hold a public workshop on 11 March to discuss proposals for several regulations and regulation amendments related to on-road heavy-duty vehicles.
At this workshop, staff will be soliciting input on proposals multiple proposals: a new regulation to harmonize with GHG emissions standards for medium- and heavy-duty engines and vehicles that US EPA adopted in 2011; amendments to ARB’s existing Heavy-Duty Vehicle GHG Emission Reduction Regulation to align with the proposed new GHG regulation; a new set of optional oxides of nitrogen (NOx) standards for heavy-duty vehicle engines more stringent than the current 2010 model year standard; and amendments to the Airborne Toxic Control Measure (ATCM) to Limit Diesel-fueled Commercial Motor Vehicle Idling to expand compliance responsibility.

ETI, Loughborough University, Johnson Matthey & Caterpillar launch £4.5M project to improve effectiveness of SCR aftertreatment systems for heavy-duty vehicles
January 15, 2013
The UK public-private partnership Energy Technologies Institute (ETI), Loughborough University, Johnson Matthey and Caterpillar have launched a new £4.5-million (US$7.2-million) technology project to improve the effectiveness of Selective Catalytic Reaction (SCR) aftertreatment systems for NOx reduction in heavy duty vehicles (HDVs).
The project aims to help HDV fuel efficiency by developing a more efficient exhaust aftertreatment system. Often diesel engine fuel efficiency is reduced by having to comply with exhaust emission standards. It is hoped that the new exhaust system developed by this project will effectively remove this constraint. The project aims to deliver fuel efficiency and CO2 benefits of between 3%-4%.

Global Commercial Vehicle meeting continues calls for global regulatory harmonization on fuel efficiency and emissions reduction
December 16, 2012
European, North American and Japanese heavy-duty vehicle and engine manufacturers continue to call for global cooperation and regulatory harmonization to improve fuel efficiency and reduce emissions from the road freight sector, according to a summary of the recent 10th Global Commercial Vehicle meeting posted by the European Association of Automobile Manufacturers (ACEA).
More specifically, the assembled chief executives of manufacturers of heavy-duty commercial trucks and engines agreed on the need to expand the application of the UN ECE’s world-wide harmonized heavy-duty certification (WHDC) procedure for engine exhaust emissions; the importance of global diesel fuel specifications; the development of globally harmonized fuel-efficiency test procedures; and the promotion of harmonization of heavy-duty hybrid certification procedures.
