摘要： In an EGR control system for a diesel engine, the EGR amount is controlled by controlling the pressure in a diaphragm chamber of an EGR valve using the output signal of a computer, responsive to signals from a plurality of engine running condition sensors, for calculating the EGR amount with corrections according to the engine running conditions and the excess air rate. In some cases, the EGR is carried out only when the rotational speed of the engine is higher than a predetermined rotational speed. Also, in some cases, the EGR is carried out when an occurrence of idling is detected, even if the rotational speed of the engine is lower than the predetermined rotational speed.

摘要： An internal combustion engine fuel injection system includes a temperature sensor for detecting the temperature of the fuel or cooling water in the engine. When the detected temperature is higher than a given value, e.g., 50.degree. C., a pressure regulator for controlling the pressure of fuel supplied to a fuel injection valve is controlled so as to increase the fuel pressure irrespective of the intake pipe negative pressure and thereby increase the quantity of fuel supplied to the engine. In the case of an electronically controlled fuel injection control system, a predetermined correction quantity corresponding to the detected temperature from the temperature sensor is added to the basic fuel injection quantity calculated in accordance with given operating parameters of the engine, thereby increasing the quantity of fuel supplied to the engine.
