Classification Of Automobile Engines


Power plant or power unit of an automobile is that component or part which produces power to drive the automobile. It is generally in the form of an internal combustion engine running on petrol or diesel.


In some cases, it can be a gas turbine or steam engine. These are called external combustion engines. However, steam engines are now obsolete and therefore not used for driving any vehicle. In case of an internal combustion engine (IC engines) combustion (burning) of fuel with air takes place inside the engine cylinder.
