PURPOSE:To prevent production of catalyst exhaust gas smell and to prevent worsening of emission, by providing an abating means which abates a time change ratio of a load signal, and a fuel feed amount computing means which computes a fuel amount depending upon an abated load signal. CONSTITUTION:A load detecting means 2 for detecting the load state of an internal combustion engine and an acceleration detecting means 3 for detecting the acceleration state of an internal combustion engine are provided. An abating means 4 abates a time change ratio of a load signal according to an acceleration state in a way that the more the degree of acceleration is lower, the more the time change ratio is abated. A fuel feed amount computing means 5 computes an amount of fuel fed from a fuel feed means 1 according to the abated load signal. Since worsening of an air-fuel ratio can be prevented from occurring irrespective of the degree of acceleration, this constitution enables prevention of production of catalyst exhaust gas smell and worsening of emission.
