うにしたことを特徴とするエンジンの制御装置。 Calculates the intake air filling amount to the engine based on the measured value of the intake flow rate measuring means, determines the basic fuel injection amount for the engine based on the calculated value, and determines the basic fuel injection amount. In an engine that obtains an appropriate engine output by correcting the intake air temperature detected by an intake air temperature sensor, the intake air temperature sensor is disposed in an intake passage downstream of a throttle valve of the engine. On the other hand, a deceleration state detection means for detecting a deceleration state of the engine is provided, and when the end of the deceleration state of the engine is detected, the correction value of the engine output based on the detected value of the intake temperature sensor is limited. An engine control device characterized by:
