EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

One significant trend is engine downsizing coupled with turbocharging. Smaller, turbocharged engines can be used to raise fuel economy while meeting or exceeding the power and torque of larger engines, allowing engine downsizing and improved fuel economy with little or no performance compromise. of new gasoline-fueled LDV sales.

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 major part of this gain is due to downsizing the engine. Earlier post.).
