摘要： An intake pipe downstream of a throttle valve is interconnected with an exhaust pipe via an EGR supply pipe and an EGR control valve is disposed in the EGR supply pipe. An engine load ratio (KLoff) in the engine steady operation with the EGR gas being not supplied, and another engine load ratio KLon in the engine steady operation with the EGR gas being supplied are expressed with respective linear functions of an intake pipe pressure (Pm) and stored in advance. The intake pipe pressure (Pm) is detected, KLoff and KLon are calculated from the detected intake pipe pressure (Pm) using the linear function expressions and, then, a difference between these values ΔKL (=KLoff−KLon) is calculated. Based on the difference (ΔKL), the EGR control valve passing-through gas amount, which is an amount of the EGR gas passing through the EGR control valve, is calculated.

摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. A convergent throttle opening, which is a throttle opening to which the actual throttle opening converges assuming that the target intake air amount is kept at the calculated target intake air amount, is calculated. A final target throttle opening is set to the target throttle opening when the engine transient operation is in process, and to the convergent throttle opening when the engine steady operation is in process. Then, the throttle valve is driven so that the actual throttle opening is made equal to the final target throttle valve.

摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. It is judged whether the target throttle opening can be realized by a step motor. A final target throttle opening is set to a maximum or minimum throttle opening which can be realized by the step motor when it is judged that the calculated target throttle opening cannot be realized by the step motor. The step motor drives the throttle valve so that the actual throttle opening is made equal to the final target throttle opening, and the intake pipe pressure is estimated on the basis of the final target throttle opening.
