Abstract
PURPOSE:To prevent the occurrence of knocking when acceleration at the time of low engine speed in an accelerated high load zone by reducing the correction of the increasing quantity of acceleration when an engine load is large while an engine speed is low. CONSTITUTION:The detected values of a throttle valve opening sensor 4, an intake air absolute pressure sensor 8, an engine speed sensor 11, a cylinder judging sensor 12, etc. are inputted into an electronic control unit 5, which operates and controls the valve opening time of a fuel injection valve 6. When the varying quantity of a throttle valve opening is above a defined value, the electronic control unit 15 judges to be an accelerating condition and read the value of acceleration increasing quantity from a map corresponding to an intake air absolute pressure and an engine speed. This acceleration increasing quantity value is set to be larger as the intake air absolute pressure gets larger and the engine speed gets smaller.
