Theoretical efficiency of heat engine
WebbCarnot’s theorem states that for a heat engine operating with a hot thermal reservoir (temperature T H ), and a cold thermal reservoir (temperature T C ), none can have an efficiency greater than that of the following cycle: 1. Isothermal, reversible expansion of the working fluid at T H 2. Webb17 dec. 2024 · The efficiency of a car engine is determined by the amount of heat energy that is converted into useful mechanical energy. In general, internal combustion engines are about 25-30% efficient, meaning that around 70-75% of the heat energy they create is wasted. There are a number of ways to improve the efficiency of car engines, including …
