Higher fuel efficiency
Web20 de jun. de 2024 · In reality, an engine that uses 30% the heat — a.k.a., energy — to force a piston down is relatively efficient. “The efficiency by which they do so is measured in terms of “thermal efficiency”, and most gasoline combustion engines average around 20 percent thermal efficiency. Diesel is typically higher–approaching 40 percent in some ... WebThe $4 per gallon gasoline prices observed in early 2008 could result in a sizable increase in fleet fuel economy - that is, an increase in average fleet miles per gallon, or MPG - of 3.27, or 14 percent, relative to 2005. There also would be a large accompanying reduction in gasoline consumption if these high prices were to remain permanent.
