Abstract

PURPOSE:To prevent the air-fuel ratio of an engine from over-concentration and avoid deterioration of its emission when the internal combustion engine is decelerated, by decreasing a feed amount of fuel in proportion to a degree of deceleration. CONSTITUTION:A detected angle thetath of a throttle angle detector 1 is applied to a differential amplifier 4 through a differentiating circuit 2 and amplifier 3. A basic fuel injection timing Ti is fed to the differential amplifier 4. An engine pulse Ne is fed to a pulse width modulator circuit 5 to excite a solenoid and start fuel supply. Accordingly, a time for the solneoid to be excited or time for fuel to be injected is decreased in proportion to a state of decreasing rate of the throttle opening at deceleration of an engine. In this way, overconcentration of air-fuel ratio and deterioration of emission in the engine can be prevented.
