Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 本発明は、EGRガスを含む吸気が流入する インタクーラの耐腐食性や冷却性能を改善し、排ガス還 流装置の耐久性を向上することにある。 【解決手段】 エンジン(内燃機関)1に設けた過給機 6のタービン11の下流側と吸気路r1との間に排ガス 還流量を調整するEGR路(排ガス再循環通路)r3を 形成し、吸気路r1のインテークマニホールド2とEG R路(排ガス再循環通路)r3の連結位置p1との間に インタクーラ4を設けた排ガス還流装置Aにおいて、イ ンタクーラ4がステンレス製で水冷式であることを特徴 とする。 (57) [PROBLEMS] To improve corrosion resistance and cooling performance of an intercooler into which intake air containing EGR gas flows, and to improve durability of an exhaust gas recirculation device. An EGR passage (exhaust gas recirculation passage) r3 for adjusting the exhaust gas recirculation amount is formed between a downstream side of a turbine 11 of a supercharger 6 provided in an engine (internal combustion engine) 1 and an intake passage r1. Intake manifold 2 of intake path r1 and EG In the exhaust gas recirculation device A provided with the intercooler 4 between the R path (exhaust gas recirculation passage) r3 and the connection position p1, the intercooler 4 is made of stainless steel and is water-cooled.
