Vehicles:
* Cars: The most common use of combustion engines is in cars. They power the wheels, allowing the car to move.
* Trucks: Combustion engines are also used in trucks for transportation of goods.
* Motorcycles: Motorcycles are powered by combustion engines.
* Airplanes: Some airplanes use combustion engines, although jet engines are becoming more common.
* Boats: Boats can also be powered by combustion engines.
Other applications:
* Generators: Combustion engines can be used to power generators, which produce electricity.
* Pumps: Combustion engines can be used to power pumps for water, oil, or other fluids.
* Compressors: Combustion engines can be used to power compressors, which are used to compress air or other gases.
* Construction equipment: Construction equipment such as bulldozers, excavators, and cranes often use combustion engines.
* Power tools: Some power tools, such as chainsaws and generators, are powered by combustion engines.
Overall, combustion engines are a versatile technology that can be used for a wide range of applications. However, they are also a major source of pollution, which is why there is a growing shift towards electric vehicles and other alternative energy sources.
