PURPOSE:To prevent knocking from occurring, by increasing a fuel injection quantity by degrees from that point that an engine comes into a state of being high load up to the specified increment value. CONSTITUTION:That whether an engine (a) comes into a state of being high load or not is detected by a high load state detecting device (b). And, in time of a high load state, a fuel injection quantity is gradually increased up to the specified increment value from that point that the engine goes into a state of being high load. Since an air-fuel ratio is controlled in a rich direction in accord with a rise of temperature in an engine combustion chamber, knocking is preventable from occurring. In addition, at an interval till the fuel injection quantity reaches the specified increment value, a rate of fuel consumption is improved. |
