Claims (1)
果に基づいて供給混合気の空燃比をフイードバツ
ク制御する空燃比制御装置であつて、エンジンの
減速時にエンジン回転数が所定回転数以下に低下
したことを検出し、該検出時点から所定時間経過
後に前記空燃比のフイードバツク制御を停止して
前記空燃比をリツチ化せしめることを特徴とする
空燃比制御装置。 An air-fuel ratio control device that detects the concentration of exhaust components of an internal combustion engine and feedback-controls the air-fuel ratio of a supplied air-fuel mixture based on the detection result, and detects when the engine speed has fallen below a predetermined speed during engine deceleration. An air-fuel ratio control device characterized in that the air-fuel ratio is detected, and after a predetermined period of time has elapsed from the time of detection, feedback control of the air-fuel ratio is stopped to enrich the air-fuel ratio.
