DIRECT INJECTION TYPE FUEL CONTROL SYSTEM FOR GAS FUEL ENGINE

摘要

According to the present invention, the electronic control unit directly controls the injector in the idle and partial load sections, and controls the injector through the pick and hold driver in the partial load section and the full load section, thereby precisely controlling the fuel amount to prevent fuel consumption. At the same time, the present invention relates to a direct injection fuel control device for a gas fuel engine designed to improve operation performance, and includes an electronic control unit (10) for comparing an engine's condition and sending an output signal, and in a partial load section and a full load section. Pick and hold driver 30 connected to the first wire 20 to drive the signal received from the electronic control unit 10 in order to reduce the operation delay time to secure a strong driving force and to secure a large amount of fuel, and the pick and hold driver ( 30) and the injector 50 connected to the second wire 40 to inject the gas fuel, and part of the idle and partial load section In FIG. 3, the third control wire 60 directly connecting the electronic control unit 10 and the injector 50 to the electronic control unit 10 directly controls the injector 50 to configure the direct injection fuel control device for the gas fuel engine.
