Abstract
An exhaust gas recirculation device capable of restraining generation of condensate water in an EGR path after engine stoppage is provided. When ignition is switched from ON to OFF, fuel injection is prohibited. As a result, a gas (fresh air) that flows into a cylinder after the switching is discharged into an exhaust passage without burning. In the present invention, a valve opening timing of an exhaust valve is changed so that a high peak portion of a pulsation of the gas arises at an EGR branch point, and the EGR valve is opened. Thereby, the fresh air flowing in the exhaust passage can be introduced into an EGR passage, and therefore an EGR gas in the EGR passage can be replaced with the fresh air.
