METHOD FOR REDUCING FORMATION OF COMBUSTION CHAMBER DEPOSITS IN INTERNAL COMBUSTION ENGINE HAVING COMBUSTION CHAMBER

摘要

PURPOSE: To provide a method for reducing a formation of combustion chamber deposits in an engine using a friction modifier for combustible fuels. CONSTITUTION: The method comprises a step of combusting a fuel composition comprising a hydrocarbonaceous fuel and a friction modifier in an internal combustion engine. The friction modifier is prepared by combining an amine with a saturated carboxylic acid, thereby the formation of combustion chamber deposits in the engine is reduced relative to the formation of combustion chamber deposits in the engine combusting a fuel composition not containing the friction modifier.
