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

Green Car Congress

MAY 23, 2009

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. Source: ETH Zürich. Click to enlarge.

Using the virtual simulation environment GT-Power, this cycle is applied to a 4-cylinder SI engine. This engine model is simulated for a part-load operation point and compared with a standard 4-cylinder engine model and 4-cylinder engine model equipped with cylinder deactivation. —de Jong (2019).
