The energy conversion efficiency of a typical internal combustion engine (ICE) can vary based on the engine type, design, and operating conditions, but generally, it ranges from about 20% to 30%. This means that only 20-30% of the energy in the fuel is converted into useful work, while the remainder is lost as heat and through other inefficiencies.
For specific types of engines:
- **Gasoline engines** usually have an efficiency of around 20-25%.
- **Diesel engines** tend to be slightly more efficient, often in the range of 30-40% due to higher compression ratios and better thermodynamic efficiency.
In contrast, electric motors can achieve efficiencies of 85-95%, as they convert electrical energy into mechanical energy much more effectively.
The efficiency can also be influenced by factors such as engine size, tuning, load, speed, and the type of fuel used.
