Study on a FC Biodegradable Two-Stroke Gasoline Engine Oil
ZHANG Feng1, WANG Zhen-tao2
Abstract:To meet the increasingly stringent requirements in environmental protection, a FC biodegradable two-stroke gasoline engine oil was developed by taking PIB, ester oil and mineral oil as base stock and adding % of additive package. The inter-solubility between base stock and additives was studied. And the biodegradability, detergency and lubricity were evaluated by bench tests. The developed oil has passed all the required engine tests. Results showed that it has good performances and biodegradability, with over 60% biodegradation rate.
Key words:biodegradable; two-stroke gasoline engine oil; formula; additive; bench test
0 序言
多年来二冲程汽油发动机生产技术在不停发展，功率不停提升，使发动机热负荷增大，同时越来越严格的环境保护要求使二冲程汽油机油要含有优良的润滑性、清净性、低温流动性及低排烟性能。
国外为了处理环境污染，在二冲程汽油机油方面做了大量的工作，美国的几大石油企业，如Exxon，Lubrizol企业，尤其是Pennzoil企业［1］，研制出了生物降解性大于66%的二冲程汽油机油。
中国是摩托车生产大国，产量和社会保有量为世界第一，摩托车带来的环境污染问题已经引发全社会的重视，为此进行了可生物降解的二冲程汽油机油的研究。
1 产品规格及试验方法
所研制的FC级可生物降解二冲程汽油机油不但要满足FC级二冲程汽油机油的规格标准，而且还要满足生物降解性大于50%的条件。
FC级可生物降解二冲程汽油机油的指标、发动机台架试验、生物降解性试验方法分别列于表1和表2。
