Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

Current work on hydrogen combustion engines worldwide is predominantly being done for commercial vehicles with a relatively low specific output of around 50 kW per liter of displacement. For clean combustion of hydrogen, the turbochargers have to, on the one hand, provide around twice as much air mass as they do in gasoline engines.

PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm.

Also, higher exhaust temperatures in operating cylinders maintain aftertreatment temperatures at low load conditions and start-up. Cylinder Deactivation leverages Jacobs’ well-established componentry to disable engine valves in selected cylinders allowing a large engine to have the fuel economy of a smaller engine.

will be manufactured at the Columbus Engine Plant, with production to start during the fourth quarter of 2014. Many of our customers have asked for a Cummins alternative for gasoline or other small displacement automotive diesel engines. has been designed to fit where a comparable V8 or V10 gasoline engine was previously installed.

Bosch study highlights potential of e-fuels to reduce CO2 emissions

Green Car Congress

Even if all cars were to drive electrically one day, aircraft, ships, and even trucks will still run mainly on fuel. In this way, the cost of exhaust-gas treatment can be reduced, Bosch adds. It is already possible to manufacture synthetic fuels; Audi’s e-fuels initiative provides an example. Earlier post.) liter (US$4.47
