DOE awards Envera $2.8M to develop and to test efficient variable compression ratio engine

Green Car Congress

All three engine BSFC curves correspond to an engine speed of 2000 rpm.Click to enlarge. The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Valve events will also be adjusted with the VVA to trap more air in the cylinders when power is needed.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

For this reason, GDCI is a good candidate for aggressive downsizing, downspeeding, and boosting, which is a proven strategy for high vehicle-level fuel economy. Rebreathing is implemented using the exhaust valvetrain system, which provides a secondary exhaust lift event during the intake stroke. —Sellnau et al. kWh and FSN 0.1,
