This invention is a fuel composition for use in internal combustion engines comprising a major amount of a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, and greater than 5% by weight based on the total composition of an oxygenate selected from the group consisting of a saturated, aliphatic monohydric alcohol having on an average from 8 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons, and mixtures of the 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 reduces particulate emissions from the exhausts of diesel powered engines.
本发明是一种用于内燃机的燃料组合物,其主要成分是含有不超过 10%(按重量计)烯烃和不超过 10%(按重量计)酯的基础燃料,以及大于 5%(按重量计)的含氧化合物,该含氧化合物选自平均具有 8 至 20 个碳原子的饱和脂肪族一元醇、平均具有 5 至 25 个碳原子的一种或多种酮,以及醇和酮的混合物。燃料组合物中含氧化合物的量足以为燃料提供至少 0.5%(按重量计)的
氧气。含氧化合物可大大减少柴油发动机尾气中的微粒排放。
