    摘要: Biofuels suitable for use in an internal combustion engine contain ethanol and are denatured with a performance-enhancing component. The performance-enhancing denaturant component includes an organic ingredient selected from the group consisting of friction modifiers, lubricity enhancers, anti-oxidants, and combinations thereof. An internal combustion engine fueled by such a biofuel has improved engine performance, including: increasing lubricant oil lubricity, reducing lubricant oil degradation, increasing engine component durability, and/or combinations thereof. In certain aspects, methods of increasing fuel economy are provided. The present disclosure also provides methods of formulating such biofuels.

    摘要: In some embodiments, a deposit-forming reference fuel composition comprises a high sulfur base fuel composition in an amount greater than 50 weight % based on total weight % of the deposit-forming reference fuel composition, wherein the high sulfur base fuel composition comprises greater than or equal to 200 ppm sulfur based on total sulfur content of the base fuel composition. The deposit-forming reference fuel composition also comprises a reactive diolefin dopant; and a reaction initiating peroxide. The reaction initiating peroxide has an active oxygen content greater than or equal to 2 weight % based on total oxygen content of the reaction initiating peroxide and a half-life temperature of 80° C. to 200° C. The deposit-forming reference fuel composition is free from a detergent additive and has a concentration ratio of greater than 1:1 for the reactive diolefin dopant to the reaction initiating peroxide.
