Abstract
PURPOSE:To obtain the optimum air-fuel ratio by correcting the time lag of a linear exhaust sensor and measuring the intake air quantity, etc., corresponding to the lean spike, etc., generated in the transient operation state and allowing the correction coefficient to learn so as to cope with to the demanded air-fuel ratio on the basis of the above-described measurement value. CONSTITUTION:An air cleaner 2 communicated to the intake manifold 6 of an engine body 1 through a suction pipe 3 and an intake passage 7 formed in an intake air quantity sensor 11. A temperature compensation plug 9 and a hog plug 10 of a controller 11a for measuring the intake air quantity is installed in a bypass passage 8 installed in the intake passage 7. A detection signal supplied from the intake air quantity sensor 11 is inputted into a control circuit 17, together with each detection signal supplied from a linear exhaust sensor 13 and a throttle opening degree sensor 14. In this case, the prescribed calculation is carried out in the control circuit 17, and the actual spike generation time and the acceleration/deceleration correction coefficient are calculated, and the pertinent area of an acceleration/deceleration correction coefficient map is successively rewritten according to the result of calculation.
