Abstract
Embodiments of the invention use a gas flow to prevent adherence of a coating to portions of an engine block adjacent to a cylinder bore being coated with the coating. Embodiments may be particularly useful for applying a coating on the inner surface of the cylinder bores in one cylinder bank while protecting cylinder bores in an opposing cylinder bank, e.g., in a V-type engine. One method of applying a coating to an engine block comprises spraying the coating on an inner surface of a first cylinder bore of the engine block. The method further comprises shielding a second cylinder bore of the engine block from the sprayed a coating with a gas flow while spraying the coating on the inner surface of the first cylinder bore.
