Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Although the HPE approach can in concept be applied to both spark ignition (SI) and compression ignition engines (CI), after an evaluation of engine types, the team decided that downsized SI engines offered the best target for an HPE application. The concept engine uses the Bosch electro-hydraulic valve system (EHVS).
