FEV to show ultra-efficient, Euro 6-compliant 1.6-liter diesel engine at SAE World Congress— Autoblog Green

Advanced powertrain developerFEV, Inc., will show off its High Efficiency Combustion System (HECS) diesel engine at the 2011SAE World Congress. The HECS engine features advanced and conventional technologies to achieve low CO2 emissions and a 17-percent reduction in fuel consumption, while meeting Euro 6 emissions standards without an exhaust gas aftertreatment system.

FEV's second-generation HECS system has been adapted to a downsized 1.6L four-cylinder diesel engine. It's designed to offer specific power output of more than 100 kW/L (136 horsepower per liter). To achieve this level of power, FEV engineers designed a cylinder head that incorporates a unique variable valve lift system and equipped the engine with two-stage turbocharging. FEV's HECS system supposedly improves the gas exchange and significantly lowers charge temperatures, which leads to leaner air-fuel ratios and"ultra-low"CO2 emissions.

FEV's HECS diesel engine will be on display from April 12–14 at the Cobo Center in Detroit, MI.
