置。 In an alcohol engine equipped with an EGR device that recirculates exhaust gas downstream of an intake throttle valve via an EGR pipe, a portion of the exhaust passage is bounded by the wall of the intake manifold downstream of the throttle valve to reduce heat between intake and exhaust gas. A second heating section that forms a first heating section for performing the exchange, and also interfaces a part of the heating fluid pipe in which the heating fluid circulates with the wall surface of the intake manifold to exchange heat between the intake air and the heating fluid. the EGR pipe is provided with heat insulating means for the exhaust gas flowing therethrough;
The outlet end of the pipe is opened downstream of the throttle valve in the vicinity of the throttle valve, and the outlet end is provided with means for imparting a swirling flow to the exhaust gas flowing out from there toward the air-fuel mixture in the intake pipe. Fuel atomization accelerator for alcohol engines.
