    • A method for reducing fuel consumption in an internal combustion engine comprises operating said engine on a fuel composition comprising a major amount of fuel and a minor amount of an additive comprising an ester of a polyhydric polyether having ether oxygens and free and esterified hydroxyl groups in the polyhydric polyether backbone. One such ester additive is decaglycerol tetraoleate, which is an ester of decaglycerol and oleic acid containing an average of four adducted oleic acid units and 10-12 free hydroxyl groups.
    • 一种用于降低内燃机中的燃料消耗的方法,包括将燃料组合物操作在燃料组合物上,所述燃料组合物包含主要量的燃料和少量添加剂,所述添加剂包括具有醚氧和具有游离和酯化羟基的多羟基醚的酯 多元聚醚主链。 一种这样的酯添加剂是十甘油四油酸酯,其是十甘油和含有平均四个加合的油酸单元和10-12个游离羟基的油酸的酯。
