るエンジンの制御装置。[Scope of Claim for Utility Model Registration] An engine control device that receives detection signals from an intake air amount detection means, a roughness detection means, and a crank angle detection means and outputs them to a fuel injector and an ignition device, which controls the air-fuel ratio and ignition timing. an operating state control means for controlling at least one of the above in the lean direction for the air-fuel ratio and the advanced direction for the ignition timing; and control by the operating state control means for controlling the control target when the roughness exceeds a threshold value. In an engine control device equipped with roughness control means for controlling in the opposite control direction, when the roughness during warm-up operation is lower than a threshold value in response to a detection signal from the cooling water temperature detection means, the operating state control means controls the roughness in the opposite control direction. Control of an engine characterized by providing a cooling water temperature control means for controlling the air-fuel ratio to be richer and the ignition timing to be retarded until the control is stopped and the temperature rise rate of the cooling water reaches a predetermined value. Device.
