置。In an engine equipped with a negative pressure operated EGR valve that is operated within a predetermined load range depending on the operating state of the engine, and an air cleaner for intake air intake, an air passage downstream of the air cooler is connected to the air passage. A partially occupying oxygen enrichment device is disposed, and a valve device capable of shutting off the oxygen enrichment device is disposed in the air passage, and the valve device is actuated by the operating negative pressure of the EGR valve. An intake system for an engine, characterized in that the valve device is configured as follows, and the valve device is opened in a range from a point within the load range where the EGR valve is operated to a high load side outside the load range.
