EXHAUST GAS RECIRCULATION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

In a predetermined EGR region, an exhaust gas recirculation control device performs control to recirculate a portion of exhaust gas of an internal combustion engine (1) to a suction passage (11) through an EGR passage (31) in which an EGR valve (32) is provided. If it is detected that a fuel cut recovery condition is satisfied after a fuel cut condition is satisfied, the EGR valve (32) is closed from when the fuel cut recovery condition is satisfied until fuel gas is detected in an exhaust gas passage (21) that leads from a combustion chamber (16) to an inlet (31 a) of the EGR passage (31).
