Abstract

PURPOSE: To stop feedback control of a controller and free from malfunctions of the controller before warming-up of an engine by applying an internal resistance to an exhaust gas metering sensor.
CONSTITUTION: A revolutional frequency sensor 6, a water temperature sensor 7, a sucked air temperature sensor 8 and an O2 sensor of an exhaust system give those signals to a controller 4. The controller 4 runs a main actuator 1 and a slow actuator 2 which regulate an amount of air bled into a carbureter 5. A constant internal resistance R1 is parallelly connected to the O2 sensor 3 feeding a signal to the controller 4. The sensor 3 retains the signal for the controller 4 until an output voltage from the sensor rises up to a specific level or more. The feedback control may be released before warming-up of an engine.
