FIELD: engines and pumps.
SUBSTANCE: before the engine cranking, the inlet distributor and compressor first stage working vanes are cleaned. Prior to feeding the washing solution compressed air is additionally forced to the system of supercharging the engine bearing pre-oil chambers and injector fuel feed manifold. In some 10-15 s after washing solution feed, compressed air feed is shut off. Note here that washing solution is forced via at least one axial compressor channel injector in the direction opposite that of the flow.
EFFECT: ruled out the ingress of washing solution into fuel manifold and injectors and engine oil system.
