PROBLEM TO BE SOLVED: To prevent attachment of particles and/or corrosion due to products containing sulfur and nitrogen. SOLUTION: Components scavenged by exhaust gas, notably components of an internal combustion engine 12 and/or of at least exhaust gas circulation circuits 14, 16, 18, 20 belonging to an engine set 10 are provided, wherein the surface in contact with the exhaust gas of at least one component is provided with a protective coating comprising at least partly amorphous carbon of local structure close to diamond.
