PROBLEM TO BE SOLVED: To directly control injection processes without help of a servo system having additional errors. SOLUTION: An electronic injection mechanism for fuel of higher viscosity and operating temperature than diesel fuel has: a mechanically or hydraulically actuated high-pressure injection pump having a pump cylinder 1, in which the fuel fed from a fuel tank 8 through low-pressure circuits 11, 15 by a low-pressure transfer pump 9 is loaded at a required fuel pressure; and a magnet valve provided with a moving plate 36, which is actuated by a magnet 35 and is coupled to a control piston 18 for controlling start-up of injection and the injection amount. The control piston 18 of the magnet valve is incorporated into the pump cylinder 1 of the high-pressure injection pump and is directly controllable. |
