Abstract: A fuel additive includes 50 wt. % to less than 75 wt. % cyclic dienes and/or cyclic trienes that thermally crack into only chain branching radicals and greater than 25 wt. % to 50 wt. % organo-nitrates and/or nitro-organics. The fuel additive is combined with fuel at a combined treat rate ranging from 1000 (wt.) ppm to 3000 (wt.) ppm.

Abstract: A fuel composition is provided that contains a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of at least one p-alkoxy-N-alkyl aromatic amine and at least one dicyclopentadiene. Use of such additive compound in a combustion engine is also provided.

Abstract: Embodiments disclosed herein generally relate to the use of low concentration additives comprising a terpene and a cetane improver in diesel fuel to rapidly promote fuel atomization and air mixing in the combustion chamber and thereby increase the fuel efficiency and reduce harmful NOx and particulate exhaust emissions.

Abstract: A method for increasing a cetane number of fuel may comprise using a sonication device to expose fuel flowing through the sonication device to ultrasonic wave energy for a period of time, thereby increasing the cetane number of the fuel. The cetane number of the fuel may be increased just prior to supplying the fuel to an end user. An apparatus for increasing a cetane number of fuel may comprise a fuel dispensing system and a sonication device coupled to the fuel dispensing system. The sonication device may include a housing disposed within the fuel dispensing system, a flow conduit disposed through the housing, and one or more transducers operable to provide ultrasonic wave energy to fuel flowing through the flow conduit.

Abstract: A fuel composition is provided that contains a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of a certain aniline additive compound. Use of such aniline additive compound in a combustion engine is also provided.

Abstract: A lubricating oil composition useful for a diesel-powered engine is provided that reduces NOx emissions level produced from a diesel-powered engine. The lubricating oil comprises a base oil and at least one oil-dispersible source of HNCO such as isocyanates. A method of operating the diesel powered engine using the lubricating oil is also provided.
