DIESEL FUEL COMPOSITION

摘要

This invention is a method of reducing particulate matter emission from internal combustion engines which use a diesel fuel composition comprising a major amount of a diesel fuel having a base fuel which contains no more than 10 % by weight of olefins and no more than 10 % by weight of esters, by admixing said fuel with greater than 5 % by weight based on the total composition of a saturated, aliphatic monohydric alcohol having on an average from 4 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons and mixture of said alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5 % by weight of oxygen. The oxygenate significantly reduce particular emissions from the exhausts of diesel powered engines.
