polttomoottoriin
Polttomoottoriin, often referred to as an internal combustion engine in English, is a type of heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. The expansion of the superheated gases produced by combustion applies direct force to some component of the engine, such as a piston, turbine blade, or nozzle. This force moves the component over a distance, converting chemical energy into useful mechanical energy.
The most common types of internal combustion engines are the spark-ignited gasoline engine and the compression-ignited
Internal combustion engines are widely used in transportation, powering cars, motorcycles, trucks, buses, trains, and aircraft.
