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).

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. Earlier post.)

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.

Rice University Study and Policy Paper Find US Biofuels Policies Flawed, Recommend Fundamental Overhaul

Green Car Congress

Rather, it is uncertain whether existing biofuels production provides any beneficial improvement over traditional gasoline, after taking into account land use changes and emissions of nitrous oxide. The average cost to taxpayers for these “substituted” traditional gasoline barrels was roughly $82 per barrel, or $1.95
