Abstract
The intake pressure and temperature of a Diesel engine equipped with a supercharger are sensed and the sensed intake pressure value is divided by the sensed intake temperature value to obtain an intake density. A value indicative of the intake density is divided by a value indicative of the air-excess ratio computed in accordance with the operating condition of the engine producing a smoke-limit injection amount. The smoke-limit injection amount is compared with the injection amount corresponding to a part-load condition of the engine and the smaller one of the values is applied to a linear solenoid for controlling the fuel injection amount adjusting member in the fuel injection pump of the engine.
