An internal combustion engine (12) has a plurality of cylinders and includes an air system (52, 56, 58, 62, 66, 68) having a plurality of components. The air system includes an intake portion (56, 62) and an exhaust portion (58, 66, 68). At least one of the components (52, 56, 58, 62, 66, 68) has a protective coating that reduces a tendency of soot to adhere to the at least one component. Preferably, the protective coat also reduces a tendency of the at least one component to undergo corrosion. |
