Abstract

PURPOSE: To obtain a optimum fuel injection timing over the whole running range under various environmental conditions by providing a fuel injection timing adjusting device with a timer consisting of one piston and one magnet valve for adjusting the fuel injection timing.
CONSTITUTION: A Diesel engine 2 has an injection nozzle 6 to which fuel is supplied from a fuel tank 4 through a pipe 5 by a fuel injection pump 3. Fuel injection timing of the engine 2 is adjusted by means of a timer 7 which is controlled by a control unit 8. The control unit 8 receives outputs from a rotational frequency detector 9, a water temperature sensor 10, a top dead center timing detector 11, a needle valve lift sensor 12 and a load detector 13 to generate a control signal S6. Depending upon the control signal S6, the timer 7 controls the magnet valve 38 to suitably open. If a cylinder chamber 17 is made open to the atmospheric air, a piston 15 is moved rightwardly to thereby displace a roller holder 24 through a rod 23 to thus control the injection timing.
