6.6.1 FUEL INJECTION PUMP
Injection pump is distributor injection type (VE) mounted on the gear case ange and driven by injection pump gear. The
fuel is supplied in each cylinder by one plunger rotation and reciprocating motion. The fuel is sucked from fuel tank by
external feed pump and internal feed pump. And then fuel send to injection pump through fuel lter. Low-pressure fuel
sucks in pump chamber and is controlled by regulating valve. The fuel enter high pressure chamber through barrel suction
port via injection pump head path from pump chamber. High-pressured fuel made by plunger inject through injection valve
according to injection timing. Excessive fuel in injection pump returns fuel tank through fuel return hose via over ow valve.
The injection pump is cooled and lubricated by the fuel circulation. Remaining fuel also returns fuel tank
through over flow hose after collecting in the injection pump. Water in the fuel reduces pump useful life.
Therefore must manage not to enter water, dirt into the fuel system.
