摘要 |
<p>The invention provides the use, as an additive in a diesel fuel comprising a major proportion of a diesel oil, of an effective concentration of a polyether derivative of the general formula (I): R<1>-O-(R<3>-O)x-R<2>, wherein each of R<1> and R<2> independently represents a hydrogen atom, a C1-30 alkyl or alkenyl group optionally substituted by one or more amino or hydroxy groups, or a C2-7 alkanoyl group, x has an average value in the range 2 to 200, and each moiety R<3> is independently selected from C2-4 alkylene moieties, for reducing white smoke emissions under cold-running engine conditions, and a method of operating a diesel engine under cold-running conditions with reduced white smoke emissions.</p> |
