无灰型燃油节能剂既能节能和消除碳烟，又不会造成二次污染，是燃油节能剂发展的必然趋势。开发一种不含金属元素，汽油和柴油通用，具有减污节能功效的ＦＡ－１无灰通用型燃油节能剂。研究表明，ＦＡ－１的最佳用量为０．１％（ｖ），发动机台架试验节油率４．７％，道路行车试验平均节油率１５％～２０％（新车≮１０％）；还具有助燃、消烟、减少ＨＣ和ＣＯ排放、除积炭、降低发动机噪音和提高机械动力等功能。在对试验结果进行理论分析基础上，提出了ＦＡ－１节能剂改善燃油雾化质量和与氧发生三分子生链反应的作用机理。 Ashless fuel-saving energy-saving agent can both save energy and eliminate soot, and will not cause secondary pollution, is the inevitable trend of the development of fuel energy-saving agent. Development of a non-metallic elements, gasoline and diesel common, with pollution-saving energy-saving FA-1 ash-free general-purpose energy-saving fuel agent. The results show that the best dosage of FA - 1 is 0.1% (v), the engine bench test saving rate is 4.7% and the average road saving test fuel saving rate is 15% ~ 20% (10% for new car). Also has combustion, smoke, reduce HC and CO emissions, in addition to carbon deposition, reduce engine noise and improve mechanical power and other functions. Based on the theoretical analysis of the experimental results, the mechanism of FA-1 energy-saving agent to improve the quality of fuel atomization and the three-dimensional chain reaction with oxygen is proposed.
