U Wisc. study explores effects of biodiesel-gasoline blend in diesel engine

Green Car Congress

One high-efficiency combustion concept under investigation is gasoline compression ignition (GCI)—the use of gasoline-like fuels to deliver very low NO x and PM emissions as well as high efficiency in a diesel compression ignition engine. The commercially available gasoline base had an octane number of 87.

Gasoline consumption per capita in 2020 was on par with that in 1965

Green Car Congress

This analysis examines the effect of this downturn in driving on gasoline consumption (both total and per capita), and places the consumption in 2020 in a historical context. The results show that gasoline consumption per capita in 2020 was on par with that 55 years ago. Total consumption. Total consumption (millions of gallons).
