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

Green Car Congress

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. The hardware concept.

Ricardo’s “deep” Miller cycle concept: Magma

Green Car Congress

In its new report on downsized and boosted gasoline engine technologies ( earlier post ) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine. A long exhaust stroke then extracts maximum efficiency.
