針對現(xiàn)行汽油清凈劑的缺陷，本研究利用表面活性劑技術(shù)、微乳化技術(shù)、除炭技術(shù)，配合其它助劑，對其進(jìn)行改良，得出初步配方.經(jīng)多步優(yōu)化改進(jìn)實(shí)驗(yàn)，最終研制成一種新型具節(jié)能、環(huán)保與經(jīng)濟(jì)效應(yīng)的“三位一體”汽油清凈劑（NDEEE）。各項(xiàng)數(shù)據(jù)分析，實(shí)際驗(yàn)證及成本核算均可證明NDEEC的階段最優(yōu)性。使用添加NDEEC的汽車百公里油耗為6.9升，與使用93號(hào)標(biāo)準(zhǔn)汽油相比，節(jié)省約11%；在尾氣排放方面，CO%為0.31%（怠速工況）和0.22%（高怠速工況），分別比使用93號(hào)標(biāo)準(zhǔn)汽油降低約25%（怠速工況）和12%（高怠速工況），HC含量為55ppm（怠速工況）、45ppm（高怠速工況），分別比使用93號(hào)標(biāo)準(zhǔn)汽油降低約31%（怠速工況）和30%（高怠速工況）。該方案具有很好的應(yīng)用推廣價(jià)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.
