PURPOSE:To permit the always stable start by varying the increased amount of fuel on start according to the amount of deposit (adhering substance such as minute carbon particles) by installing a means for detecting the amount of adhesion of the deposit onto the suction system of an engine. CONSTITUTION:When a deposit 21 adheres onto the suction system part of an engine, a portion of the jetted-out fuel is absorbed into the deposit, and the uniformity of the air fuel ratio is disturbed in the transient operation of the engine. Then, a detecting means 1 for detecting the amount of deposit on the basis of the output signal of an O2 sensor is installed, and a calculating means 4 calculates the correction portion of the fuel injection amount on engine start according to the detected amount of deposit. When a detecting means 2 detects the start of the engine, a calculating means 5 corrects the fuel injection amount calculated in a calculating means 3 by the above-described correction portion according to the operation condition, and then a fuel injection means 6 is controlled according to the fuel injection amount after correction.
