摘要： 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.

摘要： An engine has a bypass around a throttle valve and a solenoid operated idle speed control valve provided in the bypass. The control valve is driven by driving pulses duty ratio of which is dependent on a coolant temperature and an old learning correction value. Temperature of a solenoid of the control valve is converted to voltage. A map is provided for storing normal temperature duty ratios, one of which is derived from the map in dependence on duty ratio of the driving pulses and the voltage. Difference between the duty ratio of the driving pulses and the derived normal temperature duty ratio is stored in a memory. When an ignition switch is turned off, the difference is added to the old learning correction value to produce a new learning correction value. The new learning correction value is used for a subsequent engine operation instead of the old learning correction value.

摘要： A throttle position sensor is provided for detecting opening degree of the throttle valve at regular intervals to produce an opening degree signal dependent on the detected opening degree. A memory has a stored opening degree signal. A detected opening degree signal detected by the sensor is compared with an opening degree signal stored in the memory. The stored opening degree signal is rewritten with the detected opening degree signal when the latter is larger than the former. Thus, a signal representing a maximum opening degree is stored in the memory.
