Abstract

In an internal combustion engine having several combustion chambers formed in in-line cylinders wherein an air/fuel mixture can be combusted and which include a common cylinder head, with discharge passages formed within the cylinder head and extending to a common confluence zone in communication with a discharge manifold, the common confluence zone is delimited on a first side (A) by at least one cylinder head wall and a separate shell element on a second side mounted to the outside of the cylinder head, the shell element being curved funnel-like for conducting the exhaust gas away from the engine.
