<P>PROBLEM TO BE SOLVED: To secure the quantity of EGR gas to be introduced to a cylinder much more without enlarging an opening area of an EGR introduction nozzle or increasing a differential pressure between an intake system and an exhaust system. <P>SOLUTION: In an exhaust reflux device for an internal combustion engine including an EGR device for returning a part of exhaust gas of the internal combustion engine to a combustion chamber as EGR gas, a heat exchanger is disposed so as to be connected to an EGR passage for returning EGR gas to an intake system of the internal combustion engine and to the intake system of the internal combustion engine. In the heat exchanger, heat exchange is performed without mutually mixing EGR gas and intake air. <P>COPYRIGHT: (C)2013,JPO&INPIT |
