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

Green Car Congress

A team from National Tsing Hua University, Taiwan, reports that a low-temperature solid oxide fuel cell (SOFC) emissions control system for lean-burn engines can simultaneously reduce the high concentrations of NO x and oxidize hydrocarbon (HC) emissions.

Bentley introduces its first diesel: Bentayga Diesel with 48V system & electric supercharger

Green Car Congress

liter, 32-valve V8 engine. liter V8 engine is mated to a ZF eight-speed automatic transmission. Variable-geometry, sequential twin-scroll turbochargers are powered by the exhaust gases, while a third electric supercharger—powered by Bentley’s innovative 48V system—spools up within 30 microseconds to eliminate turbo lag.
