Abstract

PURPOSE: To provide stable driving without excess control, by improving the transition characteristic of open loop control and feedback control.
CONSTITUTION: A pulse solenoid valve 19 is controlled by a micro computer 20 which is mainly composed of a micro processor 21, memory 22 and interface 23. The micro processor 21 provides feedback control of suction air by changing the duty of a pulse signal which drives the solenoid valve 19, so that the real engine revolution agrees with the target revolution, while the duty of pulse signal is changed in accordance with the temperature of cooling water during the open loop control. Selection of the feedback control depends on the conditions of a throttle valve switch 27, neutral switch 28, vehicle speed switch 29 and fuel feed control.
