PURPOSE:To effect a good fuel control by a method wherein a control circuit, controlling the system so as to make the ratio of a total amount of gas supplied into a combustion chamber to the amount of fuel constant in accordance with the temperature of gas in a suction pipe, a pressure in the suction pipe and the revolving speed of the engine, is provided in this system. CONSTITUTION:The pressure in the suction pipe of the engine is detected by a pressure sensor 14 while the revolving speed thereof is detected by a crank angle sensor 22. The control circuit 18 controls the amount of fuel supplied into the combustion chamber 29 as well as the amount of exhaust gas recirculated into the combustion chamber 29 through an EGR valve 25, in accordance with both of the signals of the detections. In this controls system, the amount of fuel is controlled so as to make the ratio of the total amount of gas to the amount of the fuel constant. Thus, the discharging amount of NOX may be restricted within a specified value and the rate of the fuel consumption of the engine may be controlled at the best. |
