Filed: 1984-05-19
Abstract: PURPOSE:To prevent the output of an engine from varying upon change-over from the condition in which a secondary intake-air valve rests to the condition in which first and second intake-air valves operate, by temporarily increasing the amount of fuel fed to an intake-air passage before the change-over. CONSTITUTION:In the main control section of a controller 29, required basic data are multiplied by compensating coefficients in accordance with data from sensors 17-28 to obtain a fuel injection pulse width, and the amount of fuel fed to a combustion chamber in an engine E by means of a fuel supply amount setting means M4. If the high load condition of the engine E is detected during a period exceeding a set time and a high temperature of supplied air is detected, a fuel increase amount control means M5 controls fuel injection valves 9, 10 such that fuel in an amount which is larger than a supply amount set beforehand by the means M4, is fed a combustion chamber to enrich the air-fuel ratio, in preference to the fuel supply amount setting means M4. Thus, the air-fuel ratio of mixture in an intake air passage 1 becomes suitable, thereby it is possible to prevent the output of the engine from varying and so forth upon change-over of intake valves.
