PROBLEM TO BE SOLVED: To prevent the deterioration of engine startability caused by a remaining EGR gas at a restart of an engine even if an EGR gas remains in an intake passage at a stop of the engine.SOLUTION: A control device of an engine 1 having a supercharger 7 and a low-pressure loop type EGR device comprises: an electronic throttle device 14 (throttle valve 21) which adjusts an intake air amount of an intake passage 3; operation state detection means which detects an operation state of the engine 1; and an electronic control device (ECU) 50 which controls the electronic throttle device 14 and the EGR valve 18 on the basis of the detected operation state. The ECU 50 controls the electronic throttle device 14 and the ECU valve 18 so as to be valve-closed at a stop of the engine 1. Here, the ECU 50 forcibly controls the electronic throttle device 14 so as to be valve-opened until the stop of the engine 1 is completed in order to scavenge the EGR gas remaining in the intake passage 3 at an upstream side of the electronic throttle device 14 at the stop of the engine 1. |
