Abstract (en)

[origin: EP1520973A2] The internal combustion engine for a motor vehicle has a combustion chamber with an inlet port for the feed of combustion gas, an exhaust port for the discharge of combustion products, and a fuel supply unit for the feed of liquid fuel. The exhaust port is located in an exhaust manifold of thin-walled metal sheet with a roughened inner surface for the absorption of unburnt or partially burnt fuel. The exhaust manifold is constructed from at least two separate part shells formed in a non-cutting process, with the inner surfaces roughened by a non-cutting and/or a cutting treatment.
