FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed method to reduce separation of deposits in combustion chamber of internal combustion engines with spark ignition in which deposits are formed in combustion chamber includes delivery of fuel with addition containing metal compound into internal combustion engine with spark ignition. Said metal containing compound is delivered in amount sufficient for effective reduction of separation of deposits in combustion chamber. Method to decrease exhaust when starting internal combustion engine with spark ignition from cold includes reduction of separation of deposits in combustion chamber of internal combustion engine with spark ignition. Metal containing compound is delivered in amount sufficient for effective decrease of exhaust when starting engine from cold.
EFFECT: reduced separation of deposits in combustion chamber and exhausts when starting engine from cold.
