Abstract:
The present invention relates to methods of fueling an internal combustion engine, and composition, that provide improved nitrogen-free detergency in the engine, particularly in the area of injector deposit control. The present invention also provides methods of providing both improved detergency and improved corrosion inhibition, while avoiding compatibility problems with fuels and/or while limiting the amount of nitrogen delivered to the fuel from the deposit control additive.

Abstract:
A method of inhibiting the formation of foam in a mixture comprising water and hydrocarbons, the method comprising contacting the mixture with a composition which comprises at least one ionic liquid. The ionic liquid is preferably a poly(hydroxycarboxylic acid) amide salt derivative or an alkyl ethoxylate phosphate salt.
Abstract:
The present invention is directed toward compositions suitable for use as dielectric fluids, lubricant fluids and biodiesel fluids. Compositions described herein are obtained from a saturated, unsaturated or combinations of both monol, diol, triol or polyol acyl ester based fluid and/or a non-ester based fluid and 2,4,6-tris(di-C1-C6-alkylaminomethyl) phenol and/or the carboxylic acid salt of 2,4,6-tris(di-C1-C6-alkylaminomethyl) phenol. These compositions demonstrate improved oxidative stability and/or hydrolytic stability at higher use temperatures.
Abstract:
The present invention provides a poly(hydroxycarboxylic acid) amide salt derivative having formula (III): [Y—CO[O-A-CO]n—Z—R+]mpXq− (III) wherein Y is hydrogen or an optionally substituted hydrocarbyl group, A is a divalent optionally substituted hydrocarbyl group, n is from 1 to 100, preferably from 1 to 10, m is from 1 to 4, q is from 1 to 4 and p is an integer such that pq=m, Z is an optionally substituted divalent bridging group which is attached to the carbonyl group through a nitrogen atom, R+ is an ammonium group and Xq− is a non-sulphur-containing anion. Furthermore, the present invention provides a lubricating composition and a fuel composition containing the poly(hydroxycarboxylic acid) amide salt derivative and the use of the poly(hydroxycarboxylic acid) amide salt derivative for decreasing the phosphorus volatility of a fluid.
Abstract:
The present invention relates methods of operating internal combustion engines and particularly marine diesel engines that result in reduced levels of sulfur trioxide, and similar corrosive and/or harmful byproducts of combustion. The present invention allows for the use of a lower TBN engine lubricant with a fuel of given sulfur and/or the use of a higher sulfur content fuel with an engine lubricant of a given TBN content than would otherwise be possible, without risking corrosive damage to engine.
Abstract:
Disclosed herein is an apparatus and method for adding a lubricating additive to a diesel fuel. In one embodiment, a system for controlling the release of a fuel additive into a diesel fuel is provided, the system having: a housing having at least one inlet opening and at least one outlet opening configured to define a flow path therethrough; filter media disposed in the flow path, the filter media comprising an adsorbent that removes sulfur containing compounds from diesel fuel passing through the housing; an additive cartridge configured to disperse a lubricating additive into the diesel fuel; a controller for controlling the amount of lubricating additive that is released from the additive cartridge into the diesel fuel; and at least one sensor configured to monitor the lubricant additive content in the diesel fuel and provide a signal indicative of the lubricant additive content in the diesel fuel to the controller, wherein the controller releases the additive from the additive cartridge based upon the signal received from the at least one sensor.
