Vehicles:
* Cars: The vast majority of cars on the road are powered by gasoline or diesel combustion engines.
* Trucks: Heavy-duty trucks, delivery vehicles, and semi-trailers rely heavily on combustion engines.
* Motorcycles: Many motorcycles still use combustion engines, although electric motorcycles are becoming more popular.
* Aircraft: Airplanes and helicopters use jet engines, a type of combustion engine, for propulsion.
* Ships: Many ships use diesel engines for propulsion.
* Trains: Some locomotives use diesel or gas turbine engines.
Other Applications:
* Power generation: Combustion engines are used in power plants to generate electricity, particularly in smaller, off-grid applications.
* Construction equipment: Bulldozers, excavators, and other construction equipment often use diesel engines.
* Agricultural equipment: Tractors, combines, and other farm equipment rely on combustion engines for power.
* Generators: Portable generators used for backup power often utilize gasoline or diesel engines.
* Industrial applications: Combustion engines power pumps, compressors, and other industrial machinery.
* Recreational vehicles: Boats, motorcycles, and some recreational vehicles use combustion engines.
Note: While combustion engines remain widely used, their dominance is facing challenges from alternative power sources, such as electric motors and fuel cells. These alternatives are becoming increasingly viable, particularly in areas like passenger vehicles and power generation.
