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.

Eberspächer introducing diesel fuel-cell APU at IAA; planned market introduction in US in 2017
July 18, 2014
|Basic elements and operating principle of the diesel fuel-cell APU. Click to enlarge.|
At the upcoming IAA in Hanover, automotive supplier Eberspächer is presenting a fuel-cell APU (auxiliary power unit) for commercial trucks that converts diesel efficiently to electricity and thereby supplies the required power to all on-board consumer components such as the air-conditioning system or the refrigerator units.
As a result, the load for electricity generation can be taken off the engine or generator with a resulting decrease in fuel consumption and emissions. In future generations of trucks, components still driven mechanically today could thus be powered electrically at considerably less expense, the company suggests.

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.

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.

|Hino Profia with an electric refrigerator system. Click to enlarge.|
Hino Motors, Ltd., a Toyota Group company, and DENSO Corporation have jointly developed the first electric refrigerator system for heavy-duty trucks using a hybrid unit. This system is being applied in the Hino Profia, which will be released on 1 February in Japan; Hino is targeting annual sales of 180 units.
Hybrid trucks conventionally use energy generated from hybrid systems to assist the vehicle’s driving. However, this new truck uses energy from hybrid unit only for the new electric refrigeration system. The compact and light-weight hybrid unit—also applied in the Hino Dutro Hybrid (Hino 300 outside of Japan)—was optimized as an energy source for this new refrigerator. With the combination of Hino’s hybrid powertrain system technology and DENSO’s electric refrigerator system technology, the two companies have developed a high-quality refrigerator system that helps improve fuel economy, improves refrigeration performance, and is quieter when operating.

|2013 STO-AVT electric bus test results chart: BYD Electric Bus energy consumption (Wh/km) over speed (km/h). Click to enlarge.|
The first phase of a ten-month trial for a 40-foot BYD battery-electric bus (which commenced the Summer of 2013) was completed in Gatineau, Québec and Ottawa, Ontario in December. (Although the bus drive is zero-emissions, in frigid weather bus-heating was supplemented with a small diesel heater integrated into the bus).
The evaluation, performed by the Société de transport de l’Outaouais (STO) in conjunction with AVT (the Société de gestion et d’acquisition de véhicules de transport), found that the average speed of drivers on Gatineau and Ottawa routes was 23 km/h (14 mph), and the resulting distance the BYD bus could travel at this average speed was 250 km (155 miles)—the equivalent of 1.3 kWh/km without air-conditioning and 1.5 kWh/km with air-conditioning, and full passenger loads).
Scania adds 13-liter biodiesel engines to its Euro 6 range
January 23, 2014
|Torque and power curves for the 490 hp biodiesel engine. Click to enlarge.|
Scania is introducing two Euro 6-certified, 13-liter truck engines that can run on any diesel blend, right up to 100% biodiesel (EN 14214). The versions certified for biodiesel operation are the modular, six-cylinder, 13-liter 450 and 490 hp engines with SCR and EGR aftertreatment systems. In October 2013, Scania had introduced its robust five-cylinder, 9-liter biodiesel engine in two different output versions, 320 hp and 360 hp.
The basic model of the 450 hp (336 kW) engine offers 2,350 N·m (1,733 lb-ft) of torque from 1,000 r/min, while the 490 (365 kW) produces 2,550 N·m (1,881 lb-ft) from 1,000 r/min up to 1,300 r/min. Output declines a maximum of 8% when the engines are run on 100% biodiesel fuel (due to the lower energy content in biodiesel).

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports
December 16, 2013
Reflecting slow growth in travel and accelerated vehicle efficiency improvements, US light-duty vehicle (LDV, cars and light trucks) energy use will decline sharply between 2012 and 2040, according to the US Energy Information Administration’s (EIA’s) Annual Energy Outlook 2014 (AEO2014) Reference case released today.
AEO2014 includes a new, detailed demographic profile of driving behavior by age and gender as well as new lower population growth rates based on updated Census projections. As a result, annual increases in vehicle miles traveled (VMT) in LDVs average 0.9% from 2012 to 2040, compared to 1.2% per year over the same period in AEO2013. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

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. (Earlier post.)
Ricardo report finds hybrid buses have higher regulated emission intensities than conventional buses; need for whole vehicle testing
December 09, 2013
While technologies for low carbon buses such as hybridization offer the prospect of significant reductions in fuel consumption and CO2 emissions compared to conventionally powered vehicles, the improvement in terms of regulated emissions (criteria pollutants) may not be as great, according to a new report by Ricardo. Local emissions from buses are of particular significance, as the vehicles mainly operate in urban areas.
The UK’s Low Carbon Vehicle Partnership (LowCVP) commissioned the review of the air quality impacts arising from the recent rapid increase in the number of low carbon buses in the UK, a result of subsidies provided through the Government’s Green Bus Funds. The UK now has around 1,300 low carbon buses in operation. The new report recommends that the legislation needs to consider hybrid technology impacts in the test processes to avoid potential unintended consequences in terms of local emissions.

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.

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.
