Beschreibung
Zusammenfassung:	A fuel composition comprises a combustible hydro carbonaceous liquid fuel, lubricant, detergent, and molybdenum source. The lubricant comprises an oil of lubricating viscosity. The detergent comprises an alkaline earth metal-containing compound. Independent claims are also included for the following: (1) controlling a deleterious effect on exhaust emissions after-treatment and control devices of metal contaminant(s) and their compounds in exhaust stream from combustion of combustible fuel composition in combustion system of two stroke engine comprising intaking fuel composition into combustion system of engine, combusting the hydro carbonaceous fuel in the combustion system to produce combustion products, contacting molybdenum with alkaline earth metal(s) and their compounds in combustion products, flowing the combustion products over catalyst, sensor, and/or on-board diagnostic device; (2) improving durability of after-treatment device for two-stoke engine combustion system comprising contacting fuel composition with molybdenum source to interact with contaminants containing alkaline earth metal (compounds) in fuel composition and combustion products; and (3) a motorcycle comprising two stroke engine with combustion chamber for combusting fuel composition, fuel composition introducing mechanism, fuel combustion initiating composition, combustion product conveying mechanism, and pollutant reducing mechanism.
