Beschreibung
Zusammenfassung:	PURPOSE: To provide an improved fuel composition for two-stroke engines, and a method of using, and an apparatus for using the fuel composition to improve combustion efficiency in a combustion unit, and which additionally or alternatively improves durability of an associated exhaust after-treatment system. CONSTITUTION: The fuel composition comprises a combustible hydrocarbonaceous liquid fuel, a lubricant comprising an oil having a lubricating viscosity, a detergent comprising an alkaline earth metal-containing compound and a molybdenum source. The method comprises steps of (a) taking the fuel composition into a combustion system of a two-stroke engine; (b) combusting the hydrocarbonaceous fuel in the combustion system to produce combustion products comprising at least one material selected from the group consisting of alkaline earth metal and compounds thereof; (c) contacting the molybdenum with at least one of the alkaline earth metal, and compounds thereof; and (d) flowing the combustion products over at least one of a catalyst, a sensor, and an on-board diagnostic device, or a combination thereof; wherein the molybdenum interacts with at least one of the alkaline earth metal or compounds thereof effective to increase detergency, as compared to conducting the same method without including the molybdenum source in the fuel composition, and without blocking the catalyst, sensor and/or on-board diagnostic device.
