Abstract

PURPOSE: To improve control performance without abnormal revolution in case of selecting between open loop control and feedback control, by changing control value even during open loop control in accordance with engine temperature.
CONSTITUTION: A solenoid valve 19 is controlled by a micro computer 20 mainly composed of a micro processor 21, memory 22 and interface 23. The micro processor 21 discriminates whether or not to provide feedback control in accordance with conditions of a throttle valve 27, neutral switch 28, vehicle speed switch 29, etc. and fuel on/off control, and provides feedback control by changing the duty of pulse signal only when the occasion calls and otherwise provides open loop control. During the open loop control, the control value, that is, the duty of pulse signal is changed in accordance with the temperature of cooling water.
