FIELD: engines and pumps.
SUBSTANCE: method for washing and preserving the gas-air path of the engine is implemented during engine idling. At the first step, the formed fine-dispersed drops of the washing-preserving solution are supplied to gas-air path in a high-pressure air flow passing through the body of the spraying device (21). At the second stage, washing and preservation are carried out by flow of air when the supply of washing-preserving solution is switched off, after which air supply and the engine are switched off.
EFFECT: invention improves the quality of washing and preservation of the engine.
