Title: Fuel injection device for engine
Inventor: HANDA TOSHIHIRO
IPC: F02D41/10
Filed: 1988-09-19
Abstract: PURPOSE:To enable the correction of acceleration to be prevented from its wrong dicision based on the pulsation of intake air by inhibiting the correction of acceleration in the time of deceleration though a throttle opening decreases to a predetermined value or less. CONSTITUTION:When a throttle opening is increased, an intake air amount, detected by an air flow meter 24, is also increased, and being based on a fluctuation condition of the intake air amount detected by the air flow meter, the correction of acceleration is executed. On the contrary, the throttle opening is decreased, when it is decreased to a predetermined value or less, the detected intake air amount decreases generating pulsation, and it causes a case to be generated such that the fluctuation condition of the detected intake air amount is wrong decided as the condition of performing the correction of acceleration. Consequently, the correction of acceleration is inhibited in the time of deceleration in the time of deceleration with the throttle opening in not more than the predetermined value. Thus in the time of deceleration with the throttle opening in the predetermined value or less, wrong decision performing the correction of acceleration due to the pulsation of intake air can be prevented.
