California approves sale of DME as compression-ignition engine fuel
February 27, 2015
The California Department of Food and Agriculture has approved specifications for dimethyl ether (DME) used as fuel in compression ignition engines. (The Department of Food and Agriculture Division of Measurement Standards has the responsibility for establishing and enforcing the quality standards for spark- and compression-ignition engine fuels sold in California. These include gasoline, diesel fuel, and other fuels such as biodiesel and hydrogen.)
This latest approval builds on earlier approvals and ongoing work by other regulatory bodies, including the US Environmental Protection Agency, the California Air Resources Board, and ASTM International, and will help accelerate commercial adoption of this low carbon fuel, commented Oberon Fuels, a California-based company that is the first to produce fuel-grade DME in North America.

Study: natural gas heavy-duty trucking fleet could benefit economy, but has mixed environmental effects
February 20, 2015
Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University.
The recent shale-driven emergence of natural gas as an abundant, inexpensive fuel in the US has raised the possibility of a “momentous shift” in the level of natural gas used in transportation. The cost advantage of natural gas over diesel fuel is particularly appealing for vehicles with a high intensity of travel and thus fuel use. In the paper, the team investigated the possibility that natural gas could be utilized to provide fuel cost savings, geographic supply diversity and environmental benefits for the heavy-duty trucking sector—and whether it can enable a transition to lower carbon transport fuels.
ICCT reviews real-world tractor-trailer fuel economy in US, China and Europe
February 15, 2015
The International Council on Clean Transportation (ICCT) has published a new paper reviewing and summarizing data on commercial vehicle sales and real-world fuel consumption for heavy-duty tractor-trailers in the three key markets of the US, China and Europe, which together account for more than 70% of HDV sales worldwide.
The review found that in the US, average tractor-trailer fuel consumption rates for the entire fleet are approximately 39 L/100 km (6 mpg). For the newest US models, fuel consumption is typically between 33 and 36 L/100 km (6.5–7 mpg). A fleet-wide analysis done for the European Commission estimates tractor-trailer fuel consumption at roughly 31 L/100 km (7.6 mpg), while tests of individual vehicles done by trucking magazines suggest somewhat higher average rates of consumption at approximately 36 to 38 L/100 km (6.5 to 6.2 mpg). Chassis dynamometer testing performed as part of the regulatory development process in China reveals that tractor-trailers seem to have much higher fuel consumption rates, on average, than in the US and the EU, with laboratory results yielding an average of 44 L/100 km (5.4 mpg).

GKN to supply 500 electric flywheel hybrid drive systems to Go-Ahead Group for buses
July 29, 2014
UK transport operator Go-Ahead Group has ordered 500 electric flywheel Gyrodrive systems from GKN Hybrid Power for use in buses. The Gyrodrive Kinetic Energy Recovery System (KERS) system (featured in Audi’s LeMans-winning R18 e-tron quattro) harvests braking energy normally lost as heat.
When the driver brakes, a traction motor on one of the axles slows the vehicle, generating electricity at the same time. This electricity is used to charge the flywheel, spinning it at up to 36,000 rpm. When the driver accelerates, the system works in reverse. The energy is drawn from the flywheel and converted back into electricity to power the traction motor, which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost and weight (60 kg, 132 lbs) than battery hybrid alternatives. Useable stored energy is 1.2MJ, with peak power of 120kW.

The truck is equipped with the intelligent Highway Pilot assistance system, which enables it to drive completely autonomously at speeds of up to 85 km/h (53 mph). Daimler Trucks demonstrated the vehicle on a trip along a section of the A14 autobahn near the city of Magdeburg, in which the Future Truck drove itself under realistic driving conditions.
The Highway Pilot is comparable to an autopilot system in an airplane—probably the most advanced form of autonomous mobility in existence today, the company noted. Mercedes-Benz will unveil the complete study of the Future Truck 2025 at the International Commercial Vehicle Show (IAA) in September.
Volvo Trucks launches dual-clutch transmission for heavy-duty trucks
June 17, 2014
|I-Shift Dual Clutch provides seamless power delivery. Click to enlarge.|
Volvo Trucks is now launching I-Shift Dual Clutch, the first transmission on the market with a dual clutch system for heavy vehicles. With power-shift gear changes without any interruption in power delivery (with the exception of the range-change, which takes place when shifting from 6th to 7th gear), the 12-speed transmission maintains torque, and the truck does not lose any speed during gear changes. For the driver, the result is more comfortable and efficient progress on the road.
Transmissions with dual clutches are already used in cars, but Volvo Trucks is the first manufacturer to offer a similar solution for series-produced heavy vehicles. Volvo Trucks says that fuel consumption with the base I-Shift Dual Clutch is the same as with regular I-Shift. The company is offering two software packages to improve fuel economy with the unit:

EC sets out strategy to cut CO2 emissions from heavy-duty vehicles; short-term focus on measurement and reporting
May 21, 2014
Heavy-duty trucks, buses and coaches would use less fuel and emit lower amounts of carbon dioxide under a strategy adopted by the European Commission. Such heavy-duty vehicles (HDVs) are responsible for around a quarter of CO2 emissions from road transport in the EU. Without action, HDV emissions in 2030-2050 are projected to remain close to current levels.
While light-duty CO2 emissions are already being addressed by recent EU legislation, the new “Strategy for reducing Heavy-Duty Vehicles’ fuel consumption and CO2 emissions” marks the European attempt to address emissions from HDVs. The strategy focuses on short-term action to certify, report and monitor HDV emissions as an essential first step towards curbing emissions. The strategy is addressed to the European Parliament and the Council, which are invited to endorse it and help deliver the actions outlined.
The Volvo Group studies potential for dynamic charging for city buses with test electric road
May 19, 2014
The Volvo Group, in collaboration with the Swedish Transport Administration, will study the potential for building electrified roads on which city buses can be charged inductively at the same time as the bus is in operation (dynamic charging). A 300- to 500-meter electric road may be built for test operations in central Gothenburg during 2015.
The Volvo Group will develop a detailed proposal within the framework of innovation procurement from the Swedish Transport Administration. The proposal entails building a road section equipped with wireless charge technology and developing vehicles that will automatically charge their batteries when passing such a road section.
Caterpillar investigating 6-stroke engine cycle as low-emission solution
May 05, 2014
Caterpillar engineers have been exploring a novel 6-stroke compression ignition engine cycle in search of a low-emission system that retains fuel efficiency. In a paper presented at the SAE 2014 World Congress, they reported on their investigations of the 6-stroke cycle for near-stoichiometric and lean operation.
The primary difference between the conventional 4-stroke and Caterpillar 6-stroke cycle is the addition of a second compression and combustion stroke immediately following the primary combustion event. The fourth stroke omits the conventional exhaust event in order to recompress the combustion gases. This approach differs from the traditional 6-stroke approach in which water is injected into the cylinder after recompression to extract additional expansion work from the hot combustion products, the team noted.
Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel
May 01, 2014
Researchers from the University of Cambridge have conducted a comprehensive environmental cost–benefit analysis of near-term alternative bus technologies. The study considered emissions of non-methane hydrocarbons (NMHC), CO, NOx, PM2.5, sulfur dioxide (SO2), and ammonia (NH3), as well as the lifecycle climate impact of CO2 and non-CO2 greenhouse gases (GHG) on a CO2-equivalent basis.
Their findings indicated that emission control strategy retrofits are the least costly near-term intervention to reduce urban air pollution. Although hybrid buses provide net GHG reductions and air quality improvements, associated costs are higher and more uncertain than emission retrofits. Lean-burn (spark ignition) compressed natural gas (LB-CNG) delivers the lowest health impacts due to the significant reduction of PM2.5, but has relatively high associated CO2e emissions that negate the health benefits, they found. As a result, current LB-CNG vehicles are the most costly of all of the modeled technologies, they concluded. Their study appears in the ACS journal Environmental Science & Technology.

It also allows all-electric heating and 5 – 6 minute charging for the upcoming 18 m 4WD Arctic Whisper articulated bus.
The Opbrid Bůsbaar is an overhead, pantograph-based fast-charging station for buses. In the future, this technology may enable other applications such as medium-distance electric buses or even long distance buses and trucks, the company said.
NRC report offers guidance on development of Phase 2 rules to reduce fuel consumption and GHG from medium-and heavy-duty vehicles; more natural gas and aerodyanamics, expanded lifecycle considerations
April 03, 2014
Expanding the use of natural gas as a transportation fuel and greater use of aerodynamic devices on trailers are among the 17 overarching strategies recommended by a new National Research Council report for reducing fuel consumption by tractor-trailers, transit buses, commercial vehicles, trucks, and other medium- and heavy-duty vehicles (MHDVs).
The report follows a 2010 Research Council report the findings and recommendations of which informed the “Phase I Rule” on fuel consumption and greenhouse gas emissions of medium- and heavy-duty vehicles issued jointly by the National Highway Traffic Safety Administration and US Environmental Protection Agency. (Earlier post.) The new report offers guidance for the “Phase II Rule” under development, which is directed at technologies and programs in the post-2018 time frame. (Earlier post.) The committee will expand upon this new work and issue a final report in 2016 that will cover a broader range of technologies and approaches that address the 2025-2030 time frame.

Westport and Delphi sign joint development agreement to commercialize natural gas injector technology for heavy-duty applications
March 03, 2014
Westport Innovations Inc. and Delphi Automotive have signed a joint development agreement under which the two will combine their intellectual property and engineering strengths to co-develop and manufacture high-pressure natural gas fuel injectors designed for multiple heavy-duty engine original equipment manufacturers (OEMs). The first in a family of injectors to be developed will be one of the core components of Westport’s recently announced HPDI 2.0 fuel system. (Earlier post.)
Westport HPDI uses natural gas as the primary fuel in a diesel (compression ignition) cycle along with a small amount of diesel fuel as an ignition source. Core to the approach is a patented injector with a dual-concentric needle design. This allows small quantities of diesel fuel and large quantities of natural gas to be delivered at high pressure to the combustion chamber.
