Volkswagen Millerized 1.5 TSI ACT BlueMotion gasoline engine offers diesel-like fuel economy; derivatives may be applied in hybrid systems

Green Car Congress

Volkswagen has developed and deployed a gasoline engine that offers diesel-like fuel economy but is significantly cheaper to buy. By way of comparison: a conventional turbo system diverts part of the exhaust gas stream needed for the forced induction away from the turbine via a wastegate valve as a function of its operating state.

Emissions testing shows Lighting Hybrids hydraulic hybrid drive delivers significant reduction in NOx, up to 18% improved fuel consumption

Green Car Congress

The LH gasoline hydraulic hybrid shows an extreme reduction in NO x compared to a diesel baseline. Source: Lightning Hybrids. Broadly, the test results show significant reductions in NO x , particularly against a non-hybrid diesel baseline, and fuel economy improvements of up to 18% for the vehicle and under the drive cycles tested.
