学科：化学
针对现行汽油清净剂的缺陷，本研究利用表面活性剂技术、微乳化技术、除炭技术，配合其它助剂，对其进行改良，得出初步配方.经多步优化改进实验，最终研制成一种新型具节能、环保与经济效应的“三位一体”汽油清净剂（NDEEE）。各项数据分析，实际验证及成本核算均可证明NDEEC的阶段最优性。使用添加NDEEC的汽车百公里油耗为6.9升，与使用93号标准汽油相比，节省约11%；在尾气排放方面，CO%为0.31%（怠速工况）和0.22%（高怠速工况），分别比使用93号标准汽油降低约25%（怠速工况）和12%（高怠速工况），HC含量为55ppm（怠速工况）、45ppm（高怠速工况），分别比使用93号标准汽油降低约31%（怠速工况）和30%（高怠速工况）。该方案具有很好的应用推广价值。
Development of a New Gasoline Detergent --NDEEC

Some defects were found in currently prevailing gasoline detergents through the investigations on their operating principles. The project was started because gasoline detergent was a very important addictive. In this study, current formulation was modified to acquire the preliminary formulation of a new detergent under the assistant of surfactant technology, microemulsification technology and decarbonization technology. The formulation of NDEEC (a New Detergent which is environmentally friendly, Energy-saving and Cost-effective) was finally developed after a step-by-step experiment in which multiple optimizations were done logically. Theoretical explanation and pilot run verification and data analysis help to the evaluation of the sample made in each step. The final formulation (NDEEC) proved to be of the highest gasoline detergency Compared with current gasoline without NDEEC, the oil consumption of the gasoline with NDEEC is 6.9L/100km, approximately with 11% energy saving. As to emissions, CO% is 0.31% under idle conditions and 0.22% under high-speed idle conditions, which is reduced by about 25% and 12% respectively. HC concentration is 55ppm under idle conditions and 45ppm under high-sped idle conditions, decreasing by about 31% and 30% respectively.
It is proven that this project is feasible on the basis of experimental result analysis, actual verification and cost calculation. So it is believed that the formulation of NDEEC is of high value of public promotion.
