The disclosed invention relates to polymers with heterocyclic-containing groups, and to concentrates and lubricating oil compositions containing the polymers.
摘要:
The present invention provides a fuel additive composition comprising (a) an alkoxylate detergent, (b) a fatty acid or derivative thereof, or mixtures thereof wherein the additive composition is soluble in the fuel where the fuel is a blend of hydrocarbonaceous and nonhydrocarbonaceous fuel with a nonhydrocarbonaceous fuel content of at least 50 percent by weight. Additionally, the present invention further provides for a fuel composition comprising such a additive composition and such a fuel. The present invention also provides for a method of operating an engine and a method of reducing deposits in a fuel system by using such an additive composition and fuel blend.
