Abstract

PURPOSE: To obtain an adequate air fuel ratio by a method wherein waveforms in the case when the ratio is changed into a rich from a lean or reversed are corrected when low revolution and when high revolution in an air fuel ratio feedback controller.
CONSTITUTION: Quantities injected from fuel injection valves 8 jetting fuel to an engine 1 are controlled by means of a control circuit 7 receiving the signals of an intake quantity sensor 3, a revolution sensor 9 and an air fuel ratio sensor 12. In the circuit 7, the difference of controlling quantities just before both inversions is calculated when signals from the air fuel ratio sensor 12 are inverted to a rich from a lean or reversely, and the value is compared with the set value. The compared difference is counted while the value is added to or subtracted from the quantity of control in case of inversion, and proper signals corresponding to the number of revolution are put out.
