Some of exhaust gas discharged through an exhaust manifold(2) is supplied to an intake manifold(3) through the EGR pipe. The exhaust gas is firstly cooled by passing through a cooling fin(17), and then, passes through the filter. Then, HC and tar are removed from the exhaust gas. The clean exhaust gas is cooled in the cooler by heat exchange with cooling water. The exhaust gas flowing into the intake manifold by passing through a bellows(18) is mixed with mixed gas in an engine(1). Thereafter, the exhaust gas is burned and discharged. As the density of exhaust gas increased due to cooling, a high EGR rate is obtained. According to filtration, the deposition of carbon in a throttle valve is prevented.
