    • 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.
    • 目的:提供二冲程发动机的改进的燃料组合物,以及使用燃料组合物的方法和使燃料组合物提高燃烧单元燃烧效率的装置,并且还可以提供或替代地提高相关废气后处理燃料的耐久性, 治疗系统。 构成:燃料组合物包含可燃性含烃液体燃料,包含具有润滑粘度的油的润滑剂,包含含碱土金属的化合物和钼源的洗涤剂。 该方法包括以下步骤:(a)将燃料组合物装入二冲程发动机的燃烧系统; (b)在燃烧系统中燃烧含烃燃料以产生包含至少一种选自碱土金属及其化合物的材料的燃烧产物; (c)使钼与至少一种碱土金属及其化合物接触; 和(d)使燃烧产物流过催化剂,传感器和车载诊断装置中的至少一个或其组合; 其中与在不将钼源包括在燃料组合物中的情况下进行相同的方法相比,钼与至少一种碱土金属或其化合物相互作用有效地增加去污力,并且不阻塞催化剂,传感器和/ 板诊断设备。
