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

Green Car Congress

Further, there is increasing interest among stakeholders in exploring the benefits of higher octane fuels that would lead to higher compression ratios which would lead to more efficient engines and reduced fuel consumption. One significant trend is engine downsizing coupled with turbocharging. Source: U.S. Click to enlarge.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

Bosch is leading a consortium in a German government-funded project to develop a direct injection system for monovalent natural gas engines—i.e., engines that run exclusively on CNG. Today’s CNG vehicles are generally bivalent, running on gasoline and CNG with engines designed for gasoline direct injection.

2025 Gas Mileage Reachable With 'Radical Downsizing' HyBoost Engine, Says Ricardo

Green Car Reports

Noticed engines getting smaller recently? Downsizing", as it''s called, involves using a smaller engine to do the work of a larger alternative--usually through turbocharging--while enjoying the fuel efficiency benefits associated with its size. Engineering firm Ricardo thinks this will continue, and not just in small.'
