MAHLE developing portfolio of solutions for fuel cell drives in commercial vehicles

Green Car Congress

Promising avenues include weight savings and extension of the cruising range in comparison with battery-powered solutions; fuel cell concepts may represent an attractive option for long-distance hauling, which requires heavy loads and large cruising ranges. As a result, the charge air coolers used must be resistant to ionized water.

liter diesel, prominently showing the closely attached exhaust aftertreatment system. For example, depending on the emission requirements, 3 different types of exhaust gas recirculation (EGR ) can be used: cooled high-pressure EGR without low-pressure EGR; cooled low-pressure EGR without high-pressure EGR; or. The EA288 2.0-liter

New Mercedes-AMG C 63 S E PERFORMANCE 680hp hybrid with technology transfer from Formula 1

Green Car Congress

Power delivery and torque build-up occur very spontaneously and without delay: as in Formula 1, the electric support of the exhaust gas turbocharger eliminates the turbo lag of the combustion engine, while at the same time the electric drive pushes powerfully from a standstill. Charging is via the 3.7 It ensures the highest level of safety.

Toyota introducing new series of gasoline engines with gain of at least 10% fuel efficiency; up to 38% maximum thermal efficiency

Green Car Congress

In a paper presented at the SAE 2014 World Congress, Toyota researchers described their work on an optimized combustion concept for turbocharged gasoline direct-injection engines that leverages optimized intake ports, dog dish-type curved pistons with a lip, and a fan injection spray to minimize flow disturbance and intensify in-cylinder flow.).

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Our test shows that as well as electric driving on renewable electricity, there are other concepts that permit long-distance, low-emission driving. During each of up to 3,000 revolutions per minute in the research engine, a minute amount of fuel shoots into the glass cylinder, is compressed and ignited, and the exhaust gas then expelled.
