摘要： A control device for an engine includes an air-fuel ratio detector detecting an air-fuel ratio of an exhaust gas of the engine. A feedback controller performs a feedback control of an amount of a fuel injection of mixed fuel including alcohol so that the air-fuel ratio detected by the air-fuel ratio detector is come close to a target air-fuel ratio, the mixed fuel supplied from a fuel feeder. A concentration estimator estimates a concentration of the alcohol in the mixed fuel based on the air-fuel ratio of the exhaust gas and a correction amount for the amount of the fuel injection controlled by the feedback control. A malfunction determiner determines that the fuel feeder has a malfunction when the correction amount is greater than or equal to a value for a period which is longer than a first period in a second period. The second period is from a first time point when the feedback controller starts to perform the feedback control.

摘要： An engine control device for detecting misfire of an engine. Based on a detected crank angle of the engine, an angular velocity at a first crank angle at which the engine speed is close to a minimum within one combustion cycle of each cylinder is calculated as a pre-combustion angular velocity, and an angular velocity at a second crank angle at which the engine speed is close to a maximum within the same combustion cycle is calculated as a post-combustion angular velocity. An amount of rotation variation caused between the first and second crank angles is calculated based on the pre-combustion and post-combustion angular velocities of the same combustion cycle, and is compared with a predetermined misfire criterion to determine whether or not misfire has occurred. When misfire is detected, a required operation is performed, for example, a warning lamp is turned on or the fuel supply quantity is increased.
