Abstract
An electronic control system for a carburetor of an internal combustion engine having an induction passage, engine cooling water and a device supplies an air-fuel mixture to the induction passage. A converter converts the temperature of the engine cooling water to a first voltage signal. A choke valve is disposed in the induction passage and a bimetal actuates the choke valve. A positive temperature coefficient heater heats the bimetal. A heater circuit produces a second voltage signal dependent on the resistance of the positive temperature coefficient heater. An air-fuel ratio controller controls the air-fuel ratio of the mixture supplied by the air-fuel mixture supply device. A calculating circuit combines the voltage signals from the converter and the heater circuit respectively and produces an electronic control for controlling the air-fuel ratio control. The electronic control is responsive to the output electric signals of the calculating circuit such that the air-fuel ratio is controlled to a value providing satisfactory cold engine operating performance.
