An internal combustion engine having a cylinder and a piston movable in the cylinder, the cylinder and piston defining a combustion chamber enclosed by the cylinder and the piston, a surface of at least one of at least one component of the combustion chamber and an adjoining space that comes into contact with at least one of a fuel-air mixture to be combusted and with motor oil has, at least in certain areas, a catalytic coating for oxidizing carbonization residues, the coating consists of a ternary vanadium oxide compound and at least one other compound of at least one metal oxide, the metal oxide is at least one of the group consisting of a cerium oxide, an oxide of another rare-earth metal, an oxide of lanthanum (La), and an oxide of a transition metal.

Internal combustion engine

An intake manifold is formed by two half-shells into which inserts are mounted to form intake ducts. To adapt the manifold to internal combustion engines of differing displacements and to achieve sealing of the intake ducts relative to an air-collecting region, the inserts are inserted into a half-shell with an overlap between adjacent parallel wall sections and the extent of the overlap is selected according to the desired cross-sectional area of the ducts. Sealing of the intake ducts is accomplished by providing seals along flanges which are spaced from the intake duct by a distance corresponding to the overlap of the parallel wall sections.
