Claims

[Scope of Claim for Utility Model Registration] An intake air amount detection means for detecting the amount of intake air flowing through an intake passage of an engine mounted on a vehicle; the engine and a wheel drive system of the vehicle to which the output torque of the engine is transmitted; a torque transmission state detection means for detecting a connection state of the vehicle; a deceleration travel detection means for detecting a deceleration travel state of the vehicle; and when the deceleration travel detection means detects the deceleration travel state of the vehicle, the intake air amount detection means a fuel supply amount calculating means for calculating a fuel supply amount corresponding to a corrected output obtained by subjecting the detected output to a smoothing process based on the detected output obtained from the means; and decelerating the vehicle by the deceleration traveling detecting means. When the running state is detected, the fuel supply amount is calculated by the fuel supply amount calculation means according to the connection state between the engine and the wheel drive system detected by the torque transmission state detection means. a fuel supply amount control means that performs an operation that calculates a change corresponding to the change in the degree of change; and a fuel supply amount control means that performs an operation to calculate a change corresponding to the change in the degree of change, and a fuel supply amount to the engine using the fuel supply amount calculated by the fuel supply amount calculation means. A fuel control device for an engine, comprising: a fuel supply means for performing the following;
