Air suction inlet channel system for a combustion engine has cooling device in inlet manifold and air flow channel to mix with returning exhaust gas

摘要

An air suction inlet channel system for a combustion engine comprises a multipart housing with an inlet manifold channel (1) with individual inlets to cylinders. There is a device (5) in the manifold to cool back-directed exhaust gas (14) comprising an air through flow channel (18) in which the exhaust gas is mixed to by-pass the cooling unit.
