ABSTRACT:
A unit injector type of fuel injection system comprising a delivery cylinder with a cylinder bore and an injection cylinder with a cylinder bore connected to and deviated from the delivery cylinder bore, a delivery plunger which is slidably fitted in the delivery cylinder bore and which defines a delivery pump chamber in the delivery cylinder, an injection plunger which is slidably fitted in the injection cylinder bore and which defines an injection pump chamber in the injection cylinder, the injection plunger being displaced by the fuel fed into the injection pump chamber, through a stroke corresponding to the amount of the fed fuel, fuel passage for feeding the fuel into the injection pump chamber, and nozzle for injecting the fuel delivered by the injection pump chamber, the injection plunger being moved under the pressure which occurs in the delivery pump chamber due to the displacement of the delivery plunger.
