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. In MY 2010, 12.5%

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.
