PROBLEM TO BE SOLVED: To achieve a target intake air amount, even if the control target value of an EGR device varies and to enhance a controllability of a supercharger containing transition, and the EGR device. SOLUTION: This device is provided with a supercharger 61 and an EGR device 62. In this case, the control target value of the EGR device 62 is controlled by a computing means 63 according to operation conditions, and the EGR device 62 is controlled by a control means 63, so that the computing result is adjusted to the control target value of the EGR device 62. Meanwhile, a target intake air amount tQac or a target supercharging pressure corresponding to an operation is computed by a computing means 65, and the working target value of the a supercharger 61 is set by a setting means 66, based on the target intake air amount tQac or a target supercharging pressure and the control target value of the EGR device 62. The supercharger 61 is controlled by a control means 67, so that the working value of the supercharger 61 is adjusted to a target value. |
