Fuel composition containing molybdenum source and metal-containing detergent, and its use in two-stroke engines

本发明涉及一种燃料组合物以及在二冲程发动机中燃烧该组合物的方法和设备，其中来自燃料的钼将和来自清洁剂或其他燃料添加剂中的碱土金属相互作用，从而有效地提高清洁性能而不增加燃料或其燃烧产物中的碱土金属或化合物含量。以这样的方式，发动机可以更清洁有效地运转，而不增加有害碱土物质及其化合物的危险性，这些物质会使催化剂、传感器和汽车车用诊断系统发生结块和中毒，这样的方式还能提高排放后处理系统的耐用性。 A fuel composition comprises a combustible hydro carbonaceous liquid fuel, lubricant, detergent, and m...

Zusammenfassung:	本发明涉及一种燃料组合物以及在二冲程发动机中燃烧该组合物的方法和设备，其中来自燃料的钼将和来自清洁剂或其他燃料添加剂中的碱土金属相互作用，从而有效地提高清洁性能而不增加燃料或其燃烧产物中的碱土金属或化合物含量。以这样的方式，发动机可以更清洁有效地运转，而不增加有害碱土物质及其化合物的危险性，这些物质会使催化剂、传感器和汽车车用诊断系统发生结块和中毒，这样的方式还能提高排放后处理系统的耐用性。 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.
