Main Engine

Houses the cylinders where combustion occurs and supports other engine components.

Seals the top of the cylinder, contains valves and fuel injectors, and withstands combustion pressure.

Moves up and down inside the cylinder, converting combustion energy into mechanical motion.

Seals the gap between the piston and cylinder wall to prevent gas leakage and control oil consumption.

Transfers motion from the piston to the crankshaft, converting linear motion into rotational motion

Converts the reciprocating motion of the pistons into rotary motion to drive the propeller.

Controls the timing of the opening and closing of inlet and exhaust valves.

Sprays fuel into the combustion chamber at high pressure to ensure proper combustion.

Delivers fuel at high pressure to the injector for combustion.

Uses exhaust gases to compress air and increase the engine’s efficiency and power output.

Stores compressed air before supplying it to cylinders for better combustion.

Collects exhaust gases from cylinders and directs them to the turbocharger or exhaust system.
