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.

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.

XL Hybrids introduces the first hybrid electric upfit for Ford F-250 pickups and chassis for commercial fleets

Green Car Congress

XL Hybrids will begin production on the new XL3 Hybrid Electric Drive System for Model Year 2018 Ford Super Duty F-250 pickups in first quarter 2018. This will be the first time that Ford F-250 trucks can be ordered by fleet customers with hybrid-electric drive technology; the XL3 system can provide up to a 25% increase in fuel economy.
