Engine Efficiency
Engine efficiency refers to how well an engine converts fuel into useful work or energy. It is typically expressed as a percentage, indicating the ratio of useful output to the energy input. Higher efficiency means more of the fuel's energy is used for movement, while lower efficiency results in wasted energy, often as heat.
Factors affecting engine efficiency include design, fuel type, and operating conditions. For example, internal combustion engines generally have lower efficiency compared to electric engines, which can convert a higher percentage of energy from their power source into motion. Improving engine efficiency can lead to better fuel economy and reduced emissions.
