Rotrak testing prototype variable drive supercharger in vehicle on dyno

Green Car Congress

The company’s engineers have a prototype system running in a B-segment donor vehicle on a dynamometer and are calibrating the control strategy to prove its driveability, performance, CO 2 and fuel economy benefits. Both solutions involve part load losses which compromise some of the fuel consumption savings made by downsizing.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. For our fleet, increases in the fuel economy of 1.6% (0.5−2.4%;
