In the control system for a turbo-charged diesel aircraft engine, the engine speed and the fuel injection amount are controlled by a single control lever. However, when the control lever is operated to accelerate the engine, the fuel injection amount immediately increases to the value set by the control lever while the actual speed of the engine requires a relatively long time to reach the set speed. This may cause the actual fuel injection amount to become excessively larger than a value matching the engine speed and to produce exhaust smoke. In order to prevent this problem, the control system includes a delay control device which restricts the rate of increase in the fuel injection amount to a value less than a predetermined maximum value. By restricting the rate of increase in the fuel injection amount, the actual fuel injection amount is maintained at a value matching the actual engine speed during acceleration, and the generation of the exhaust smoke does not occur.
