Claims

[Scope of utility model registration request]

In an engine intake control device including an auxiliary air amount control valve that introduces auxiliary intake air into an intake passage downstream of the intake throttle valve, means for detecting the opening degree of the intake throttle valve;
means for detecting the vehicle speed; means for determining when the throttle valve is fully closed and deceleration based on both detected values; means for calculating the deceleration of the vehicle during this deceleration; and means for calculating the vehicle deceleration based on the vehicle deceleration. means for calculating a correction amount for correcting the opening degree of the intake air amount control valve; means for determining a control value for the auxiliary intake air amount control valve based on the correction amount; and means for determining a control value for the auxiliary air amount control valve based on the control value. What is claimed is: 1. An intake air control device for an engine, comprising: an output means for driving the engine.
