Audi using supplementary port fuel injection to address particulates from gasoline direct injection

Green Car Congress

In part-load operation, the indirect injection supplements direct gasoline injection to improve fuel economy and to reduce the output of particulates from the engine. GDI technology provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. Earlier post.).

Rheinmetall logs €250M order for electric vacuum pumps for PHEVs

Green Car Congress

Furthermore, the electrical vacuum pump is not connected to the engine oil lubrication system. The oil pump can therefore be made smaller, which in turn increases the efficiency of the drivetrain. The pumps can as well be used in fully electric vehicles and even in conventional drivetrains.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.
