Claims (1)
イルド制御弁を有し、その開度を制御することに
より、アイドル回転数を目標値にフイードバツク
制御するアイドル回転数制御装置を備える内燃機
関において、アイドル回転数のフイードバツク制
御中にアイドル回転数の実際値が目標値より所定
値以上大きいことを少なくとも１つの条件として
アイドル回転数制御装置の異常を検出する異常検
出手段と、異常検出時に少なくとも一部の気筒の
点火時期を遅らせる点火時期補正手段とを設けた
ことを特徴とするアイドル回転数制御装置の異常
対策装置。 In an internal combustion engine equipped with an idle speed control device that has an idle control valve in the auxiliary air passage that bypasses the throttle valve, and controls the opening degree of the idle control valve, the idle speed is feedback-controlled to the target value. Abnormality detection means for detecting an abnormality in the idle speed control device under at least one condition that the actual value of the idle speed is larger than the target value by a predetermined value or more during feedback control; and ignition of at least some of the cylinders when the abnormality is detected. What is claimed is: 1. An abnormality countermeasure device for an idle speed control device, characterized in that it is provided with an ignition timing correction means for retarding the ignition timing.
