This fuel is a light oil that allows it to burn by itself (self ignition). In the injection pump, each cylinder uses one injection pump to spray fuel. How the pump works Fuel injection from the fuel tank enters the fuel filter, feed pump, enters the Injection Pump, continues to the nozzle and enters the cylinder chamber, then the fuel that has not been sprayed will be returned to the fuel tank. The purpose of this analysis is to identify the differences, the damage that occurs, and how to overcome them and how to carry out maintenance. Damage that often occurs is a scratched plunger, usually caused by the use of fuel that is contaminated with other materials, and can also be caused by dirt that settles in the fuel tank carried by the fuel when the fuel is pumped into the feed where the fuel filter does not work properly. The hole for the tappet is clogged due to dirt sticking to it when the tappet goes up and down pressing the plunger.} }
