用于二冲程汽油发动机润滑剂组合物的酯基原料，它们在二冲程汽油发动过程中燃烧排放的废气中产生较少数量的可见烟雾，也不需要增加互溶性的溶剂，其１００℃粘度为３．０～２０．０ｍｍ２／ｓ，烟雾指数至少为７５。这些酯中有一些是可以生物降解的。无烟雾的二冲程发动... Ester-based feedstocks for two-stroke petrol engine lubricant compositions that produce a smaller amount of visible fumes in the exhaust of combustion exhaust during the two-stroke gasoline run and also do not require increased miscibility of the solvent have a viscosity at 100 ° C of 3.0 ~ 20.0mm2 / s, smoke index of at least 75. Some of these esters are biodegradable. Smoke-free two-stroke engine ...
