by Jack Rosebro

Recent brake feel and application issues in Ford and Toyota hybrids (earlier post) have drawn attention to the inherent complexity of hybrid and electric vehicle braking systems, which typically combine regenerative braking with conventional friction braking, antilock braking and vehicle stability control functions. Such issues are often addressed through software upgrades, either by reflashing a control module’s read-only memory or replacing the module altogether. Both Ford and Toyota have indicated that they intend to resolve their respective issues via changes in software.

Regenerative Braking. Regenerative braking is accomplished by allowing a vehicle’s electric motor-generator to spin freely, generating an alternating current which is rectified to direct current to charge the vehicle’s battery pack. The motor-generator must be connected in some manner to the vehicle’s final drive such that the vehicle’s coasting motion will cause it to rotate.

Credit: ACS, Weber et al. Click to enlarge.

Electricity generation and distribution in the US represents nearly 40% of US CO2 emissions, as well as large shares of the other pollutants. Assessing the limits of current knowledge about US grid electricity in life cycle assessment and carbon footprinting, however, a team of researchers from Carnegie Mellon University and the University of Pittsburgh have shown that differences in standards, protocols, and reporting organizations—and the use of arbitrary political borders—can lead to important differences in estimates of CO2, SO2, and NOx emissions factors, with a corresponding effect on policies.

In a paper published online 4 February in the ACS journal Environmental Science & Technology, Weber et al. discuss the implications of this “considerable divergence” and list recommendations for a standardized approach to accounting for air pollution emissions in life cycle assessment and policy analyses.

Thermochemical exhaust heat recuperation (TCR) in an internal combustion engine could result in substantial boosts in second-law efficiency (as measured in terms of single-stage work output from an ideal IC engine) for a range of fuels, according to a new study by researchers at Oak Ridge National Laboratory (ORNL). A paper on their work was published online 5 February in the ACS journal Energy & Fuels.

The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen). The syngas is then burned in the engine in place of some or all of the original fuel. Because the reforming reactions are endothermic, the researchers note, they provide a means for recycling exhaust energy in a chemical form.

European Researchers Developing Multifunctional Structural Composite Material That Can Double as Energy Storage

5 February 2010

Researchers from Imperial College London and their European partners, including Volvo Car Corporation, are developing a prototype multifunctional structural composite material composed of carbon fibers and a polymer resin which can store and discharge electrical energy and which is also strong and lightweight enough to be used for car parts. Ultimately, they expect that this material could be used in hybrid and electric vehicles to make them lighter, more compact and more energy efficient, enabling drivers to travel for longer distances before needing to recharge their cars.

In the new €3.4-million (US$4.7-million) project, the scientists are planning to develop the composite material so that it can be used to replace the metal flooring in wheel well, which holds the spare wheel. Volvo is investigating the possibility of fitting this wheel well component into prototype cars for testing purposes.

Mercedes-Benz Introducing More BlueTec EEV trucks

5 February 2010

In extending its truck range, Mercedes-Benz will be gradually introducing EEV versions in certain output classes of the Mercedes-Benz Actros, Axor and Atego up to July 2010. BlueTec EEV is already part of the extended specification for the Mercedes-Benz Econic from January 2010.

EEV (Enhanced Environmentally Friendly Vehicle) is a European classification used for engines which comply with a more stringent exhaust emission standard that reduces particulate emissions by roughly a further one-third compared to Euro 5 limits. Incentives are offered for this technology in some European countries. The engines in the OM 920 and OM 501 series have been developed even further for this purpose. Mercedes-Benz commercial vehicles equipped with this feature can be recognized by the additional “BlueTec EEV” model plate.
