燃油添加剂在控制废气排放中的研究进展

在颁布限排政策的背景条件下，综述了燃油添加剂在控制废气排放中的研究现状、作用机理、控制效果以及存在的不足之处，并且对相关的研究提出了建议，同时对燃油添加剂的发展进行了展望。燃油添加剂能够改善燃油的燃烧特性，降低氮氧化物（NOx）、一氧化碳（CO）、碳氢化合物（HC）和颗粒物（PM）的排放量，减少大气污染。燃油添加剂成为解决污染排放问题的最佳途径之一。随着技术的发展，多功能复合型燃油添加剂、有机稀土类燃油添加剂和复配型纳米燃油添加剂将会在控制废气排放中发挥关键性作用。

Research Progress in Fuel Additives in Controlling Exhaust Emissions

With promulgating emission restriction policies， this paper reviews the research status of fuel additives used in controlling exhaust emissions including mechanism， effects and existing shortcomings. Meanwhile， this paper also puts forward suggestions for related research， and looks into future prospects for development of fuel additives. The application of fuel additives can improve the combustion characteristics of fuels， reduce the emissions of nitrogen oxides， carbon monoxide， hydrocarbon and particulate matter， and decrease air pollution. The addition of fuel additives is one of the best ways to solve the pollution emission problems. With the development of technology， multipurpose compound fuel additive， organic rare-earth fuel additive and complex formulation nano fuel additive will play important roles in controlling exhaust emissions.
