New lightweight aluminum piston from Federal-Mogul enables further downsizing of gasoline engines

Green Car Congress

The Advanced Elastoval II piston enters series production later this year in a new European passenger car, where it contributes to gains in fuel economy and reductions in CO 2. Specific power outputs in engines are likely to increase from current levels of around 95 kW/L to 130 kW/L to coming years. generation pistons.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

Tsinghua studies on alcohol-gasoline dual fuel engines show fuel efficiency and particle number benefits

Green Car Congress

In a second paper, also published in Fuel , they systematically compared the stoichiometric alcohol–gasoline and gasoline–alcohol DFSI combustion for engine particle number (PN) reduction (and fuel economy improvement), also using a high compression ratio gasoline engine. Fuel economy performance of alcohol-gasoline DFSI.
