ABSTRACT:
A fuel quantity control apparatus of a supercharged diesel engine with safety measures comprises a fuel injection pump capable of increasing the fuel quantity according to the degree of supercharging, a detector for detecting the temperature in a combustion chamber or the temperature of the exhaust gas, a control circuit receiving an output of the detector, and a three-way valve driven by the control circuit to control the amount of the increase of the fuel quantity. Through the use of the apparatus when the detected temperature reaches a predetermined abnormal temperature, the amount of increase of the fuel quantity can be made zero or decreased and accidents such as melting or damage of the engine by abnormal rise of the temperature in the combustion chamber or of the temperature of the exhaust gas can be prevented.
