2. One fuel pump is fitted in front of a cylinder unit.
   The fuel pump pressurizes fuel and delivers the appropriate quantity of fuel to the fuel valve during each cycle through the fuel high-pressure pipe.
3. The fuel pump is powered by the camshaft.

Overview

1. In an electronically controlled engine, the fuel booster pump consists of a housing and a topcover. A plunger, a suction valve, a air venting valve and a hydraulic piston are fitted into them.
2. The fuel pump pressurizes fuel and delivers the appropriate quantity of fuel to the fuel valve during each cycle through the fuel high-pressure pipe.
3. The fuel pump is powered by the pressurized oil.

Overview

1. A fuel high-pressure pipe connects a fuel valve and a fuel pump.
2. 2-4 pcs. of fuel high-pressure pipes are fitted in a cylinder.
3. A fuel high-pressure pipe is designed with a dual strucute for safty reasons.

Overview

1. Exhaust valve actuator consists of a cylinder, a piston, piston rings, a non-return valve.
2. One exhaust valve actuator is fitted in front of a cylinder unit.It pressurize lub.oil and transmit it to the exhaust valve through a high pressure pipe. A exhaust valve spindle is opened at every cycles.
3. In a camshaft controlled engine, it is powered by cam.
   In an electronically controlled engine, it is powered by pressurized oil.

Overview

1. In a camshaft controlled engine , it drives FO pump and Exhaust valve actuator by cams and rollerguides.
2. 2pcs. of rollerguide (Fuel and Exhaust) are equipped with a cylinder.

Overview

1. In an electronically controlled engine, it drives FO pump and Exhaust valve actuator by pressurized hydraulic oil instead of cams and rollerguides.
2. Operating system optimaize the timing of fuel injection and valve actuation depending on the load.
3. 1pc. of a FIVA valve is fitted in front of a cylinder unit.

Overview

3. One FIVA valve is fitted in front of a cylinder unit.

Overview

1. The electronically controlled engine is equipped with multiple units.
2. It absorbs pulsation of hydraulic oil lines by sealed Nitorogen gas.
3. 1-2pcs is fitted for a cylinder unit.

Overview

1. It releases abnormally high combustion pressure in a cylinder to prevent damage.
2. 1pc. is fitted for a cylinder unit.

Overview

1. It injects compressed air into a cylinder at the correct timing when the engine starts.
2. 1pc. is fitted for a cylinder unit.

Overview

1. It pressurizes hydraulic oil and supplies it to a hydraulic jack for tightening the hydraulic nuts that secure engine components.

Overview

1. It expels combustion gas from inside the cylinder to the exterior of the cylinder during each cycle.
2. 1pc. is fitted for a cylinder unit.

Overview

1. The exhaust valve spindle seats and seals combustion gas inside a cylinder.

Overview

1. It consists of a exhaust valve spindle, a exhaust valve seat, a air cylinder and a oil cylinder.
2. It is cooled by water.
3. One exhaust valve is fitted on a cylinder unit. Lub.oil pressurized by the exhaust valve driving pump/ the exhaust valve actuator is transmitted to the exhaust valve through a high pressure pipe. A exhaust valve spindle is opened at every cycles.

Overview

1. The air cylinder closes the exhaust valve using compressed air.

Overview

1. Components that make up the combustion chamber.
2. It is cooled by water.
3. 1pc. is fitted for a cylinder unit.

Overview

1. Components that make up the combustion chamber.
2. It is cooled by oil.
3. It is equipped with 3-4pcs. piston rings that seal combustion gas.

Overview

1. It is connected to the piston crown and it transmits the force generated by combustion to the crankshaft via the crosshead and connecting rod.

Overview

1. Components that make up the combustion chamber. The surface where the piston ring slides.
2. By supplying the appropriate amount of cylinder oil, it ensures good sliding performance with the piston rings.
