GENERAL INFORMATION


The fuel is drawn out of the fuel tank by means of the feed pump which is built into the fuel injection pump. It then passes through the fuel filter and is fed to the injection pump.
The fuel is pressure is controlled by the regulating valve which is built into the pump.
Then, the fuel is compressed by the plunger and injected from the nozzles at high pressure in accordance with the injection sequence.
Engine speed (fuel injection amount) control is carried out by means of a centrifugal-type governor using a flyweight.
Fuel injection timing control is carried out by a hydraulic timer. The hydraulic timer operates by the fuel pressure inside the pump chamber. This pressure is controlled by the regulating valve.
