    A diesel engine is an internal combustion engine that operates on the principle of compression ignition. It converts chemical energy into mechanical energy by moving pistons up and down inside cylinders. Unlike gasoline engines, diesel engines induce only air into the combustion chamber during the intake stroke. Diesel engines are commonly used in vehicles, generators, and other applications.
