Abstract: The present disclosure provides a fuel composition containing gasoline, ethanol and a volatility agent, such that the cold start performance of the gasoline/ethanol blend fuel is enhanced. Also provided is a fuel composition containing ethanol and a volatility agent and also a method for improving the cold start performance of an engine.

Abstract: The present disclosure relates to the use of fuel additives in duel delivery systems contacting or combusting fuels containing ethanol, such as E85. The additives improve the properties of the resulting fuel, minimize the impact of the fuel on the components of the fuel delivery system, improve the protection of the engine and the fuel delivery system, and also enhance the benefits to the consumer and to the environment of utilizing varying amounts of ethanol as a fuel in combustion engines.

Abstract: The present disclosure provides a method to reduce wear and prevent deposit formation in an internal combustion engine, said method comprising combusting in said engine a fuel composition comprising gasoline, ethanol and at least one fuel additive. There is also provided a composition to improve wear protection in an internal combustion engine combusting an ethanol-containing fuel, said composition comprising gasoline, ethanol, and one or more fuel additive materials.

Abstract: The present disclosure provides compositions and methods for improving corrosion inhibition in engines combusting a fuel containing ethanol. In particular, E85 fuels are provided containing additives able to reduce, eliminate and/or prevent corrosion of engine combustion surfaces and surfaces of engine components exposed to the fuel containing ethanol.
