The present invention relates to the use of a diesel fuel additive comprising peroxide for reducing the fuel consumption in a diesel engine.

A fuel for an internal combustion engine includes a C.sub.5 to C.sub.30 dialkoxyalkanoate corresponding to formula (I): ##STR00001##
wherein the R.sub.1 group is H or a CH.sub.3 group, the R.sub.2 and R.sub.2 groups are alkyl groups independently selected to have 1 to 9 carbon atoms; and the R.sub.3 group is selected to have 1 to 9 carbon atoms. The compounds described herein may be used as neat fuels or mixed fuels (with diesel, biodiesel, jet fuel, marine fuel or other fuel compounds) in autoignition or spark ignition engines, such as diesel engines, gasoline (spark ignition) engines, MCCI, Homogeneous Charge Compression Ignition (HCCI) engines, or more generally in Low-Temperature Gasoline Combustion (LTGC) engines (using gasoline-like fuels), that have the high-efficiency advantages of HCCI but can operate with some level of charge inhomogeneities. Methods of making these compounds are environmentally friendly and can be done in a continuous manner.

The present invention aims a new diesel composition comprising a diesel fuel and from 0.01 to 0.8% by volume of a glycerol acetal or ketal. The new diesel composition shows a higher cetane number and better lubricity performances compared to known diesel compositions.

A process for making high density fuels having the potential to increase the range and/or loiter time of Navy platforms. Derivation of these fuels from a sustainable source will decrease the carbon footprint of the Department of Defense (DoD) and reduce reliance on nonsustainable petroleum sources. Fuels derived from bisabolene can have volumetric net heats of combustion comparable to JP-10 and can be produced from biomass sugars.

This invention relates to a process involving hydrocracking and dewaxing of a feedstream in which a converted fraction can correspond to a majority of the product from the reaction system, while an unconverted fraction can exhibit improved properties. In this hydrocracking process, it can be advantageous for the yield of unconverted fraction for gasoline fuel application to be controlled to maintain desirable cold flow properties for the unconverted fraction. Catalysts and conditions can be chosen to assist in attaining, or to optimize, desirable product yields and/or properties.
