Abstract
A negative pressure control valve () is disposed in a part of an intake passage () upstream of a confluence () of an EGR passage () and the intake passage (). When in an EGR region (Regr) where an EGR gas is recirculated to the intake passage () through the EGR passage (), the negative pressure control valve () is controlled in a manner to ensure a differential pressure between an exhaust passage () and the intake passage (). When in an operation region (R) lower in load than the EGR region (Regr), the negative pressure control valve () is controlled in a closing direction so as to suppress occurrence of noise.
