(1) Type Injection Pump Distributor
Fuel is pressed by a vane-type feed pump that has 4 vane. Pump the plunger moves straight back and forth while rotating due to the movement of the drive shaft, cam plate, plunger spring, and others. Movement of the plunger causes the fuel pressure to rise and pressed through the delivery of fuel to the injection nozzle valve.
Governor function controls the amount of fuel injected by moving the nozzle ring so as to change the current spill end of the plunger effective step. Pressure advance the timer function when injecting fuel by changing the position of the roller tappet. Fuel cut-off solenoid to close the fuel line in the pump.
(2) Injection Pump Type In-Line
Feed pump to suck fuel from the tank and press the fuel that has been filtered by the filter. Type injection pump in-line cam and a plunger having an amount equal to the number of cylinders. Straight plunger movement back and forth. Delivery valve serves to maintain the pressure in the pipe injection and injection stop quickly. Plunger lubricated by diesel and camshaft by engine oil. Governor operation of moving the control rack. Governor consists of two types: mechanical governor and governor combined (mechanical and pneumatic governor). Automatic timer move the camshaft pump
(3) High pressure pipe (delivery valve)
High pressure pipe for diesel fuel made specifically to be able to withstand the high pressure fuel. This pipe is made of a mixture of zinc plate (zinc-plated) and copper (copper lined steel)
(4) Injection Nozzle
Injection nozzle comprises a nozzle body and needle and serves to mengabutkan fuel. Between the nozzle body and needle done with precision with a tolerance of 1/1000 mm as it was when the two components need to be replaced must be replaced together.
