Additional Information

Indirect injection in an internal combustion diesel engine is when the fuel injection is not directly injected into the combustion chamber. The system delivers fuel into a pre-chamber or pre-combustion chamber, where combustion begins and then spreads into the main combustion chamber.

Direct injection in an internal combustion diesel engine, the fuel is injected directly into the combustion chamber, typically on the top of the piston which has a specially designed dome to aid in the controlled spread of combustion.
