Abstract

PURPOSE: To control the air-fuel ratio appropriately at the time of staring an internal combustion engine, by operating various actuators for controlling the air-fuel ratio depending on the temperature after cranking and starting the engine.
CONSTITUTION: In a carburetor 2 of an engine 1, there are provided a slow solenoid 3, a main solenoid 4, a fuel solenoid 5 used for increasing fuel flow, and a throttle actuator 7 for controlling air flow. Output signals of a sensor 8 for detecting the partial vacuum in the intake pipe, a sensor 9 for detecting the temperature of cooling water, an engine-speed sensor 10, and an idle detecting switch 11 are furnished to a control unit 12, in which are stored the output signals for varying the quantity of operation of the actuators depending on the temperature. At the time of cranking and starting the engine, operational positions of the actuators 3, 4, 5, 7 are determined by the speed sensor 10 and the idle switch 11 depending on the temperature at the time.
