Abstract: Fuel efficiency can be increased in a diesel engine by adding a diesel fuel additive mixture. The diesel engine fuel additive mixture is made up of the following elements: tricresyl phosphate (TCP) and a Polyetheramine (PEA) dissolved in a Glycol ether. Adding one ounce of the diesel engine fuel additive mixture per five U.S. gallons of diesel fuel can increase miles per gallon and hours of operating time while reducing the emission of nitrous oxides, sulfur, and other pollutants.

Abstract: The present invention relates to a biofuel composition comprising distilled technical cashew nut shell liquid (DT-CNSL) and atleast one petroleum product optionally alongwith plant oils and fuel additive(s). It also relates to a process for preparation of biofuel composition and a method of fueling biofuel composition.

Abstract: An aviation 100LL fuel additive formulation for lead scavenging which mitigates the detrimental effects of lead, cleans up the combustion chamber and also allows shipping and distribution by common carrier, such as UPS or FedEx. A fuel additive composition is described for aviation 100 octane Low Lead fuel, containing: (1) glycol ether 10 to 90% by volume; (2) tricresyl phosphate 5 to 10% by volume; and, (3) Polyetheramine 15 to 30% by volume. The described composition has a flash point above 141 degrees F. to enable safe shipping by common carrier. The described composition also contains polyetheramine to create a mixture which is shown to be effective in preventing plug fouling by lead and be effective in reducing combustion chamber deposits, thus providing a smooth running engine during ground operations.

Abstract: A fuel composition comprises at least a C5 isoprenoid compound or its derivative and a conventional fuel additive. The C5 isoprenoid compound or its derivative can be used as a fuel component or as a fuel additive in the fuel composition. The fuel composition may further comprise a conventional fuel component selected from a diesel fuel, jet fuel, kerosene or gasoline. Methods of making and using the fuel composition are also disclosed.

Abstract: The present invention provides a method for inhibiting deposit formation in a fuel at a temperature of from 100 to 335° C., the method comprising combining with the fuel a composition comprising: (i) high temperature antioxidant; and (ii) a deposit inhibiting compound.

Abstract: Mixtures of alkylaromatic secondary phosphate and tertiary phosphate esters prepared by reaction of phosphonyl chloride and primary phosphonyl chlorides with alkylaromatic phenols are disclosed as rust inhibiting additives for hydrocarbon based fluids.

Abstract: The lubricity (anti-wear properties) of hydrocarbon fuels, oxygenate fuels or mixtures thereof, particularly diesel or aviation fuels having reduced sulphur and/or aromatic content for compliance with regulatory requirements, is improved by the addition of a phosphorus ester or esters (phosphates and/or phosphites), or a concentrate containing the ester or esters, having a total acid number at least 1.0 mg KOH/g. The additives also improve corrosion inhibition.

Abstract: The invention relates to inhibiting the degradation of fuel oils by the addition of phosphines and phosphites. Additionally, the invention relates to inhibiting the degradation of fuel oils by drying the fuel oil and adding phosphines and phosphites.

Abstract: Compositions comprising a hydrocarbonaceous middle distillate fuel and a minor wear-inhibiting amount of a combination of (i) at least one fuel-soluble aryl phosphate of the formula(RO).sub.3 POwherein each R is, independently, phenyl or an alkyl-substituted phenyl group; and (ii) at least one fuel-soluble aryl polyphosphate of the formula ##STR1## wherein each R is, independently, phenyl or an alkyl-substituted phenyl group, Ar is m-phenylene or an alkyl-substituted m-phenylene group, and n is from 1 to 4. The combination contains from 2 to 30% by weight of component (i). These compositions are made by (a) reacting about 1.9 to about 2.1 equivalents of phenol or alkyl-substituted phenol with one equivalent of phosphoryl trihalide, and (b) reacting the intermediate product formed in (a) with from about 0.9 to about 1.1 equivalents of resorcinol or alkyl-substituted resorcinol per equivalent of phosphoryl trihalide employed in (a). Alternatively, the compositions are made by (a) reacting about 0.9 to about 1.

Abstract: This invention relates to processes and compositions for stabilizing distillate fuel oil which comprises adding to the distillate fuel oil an effective stabilizing amount of a mixture of (a) a phosphite compound having the formula ##STR1## wherein R, R' and R" are the same or different and are alkyl, aryl, alkaryl or aralkyl groups, and (b) an effective carboxylic acid having from 2 to about 20 carbon atoms, wherein the weight ratio of (a):(b) is from about 1:5 to aboug 1000:1.
