The main engine parts of a ship include the cylinder block, pistons, and crankshaft, which convert fuel into mechanical energy.

The fuel injection system and turbocharger ensure efficient combustion and air supply for optimal engine performance.

Cooling systems, lubrication systems, and exhaust systems maintain engine temperature, reduce friction, and expel combustion gases.
