Abstract:
In a method operating an internal combustion engine, a nitrogen-containing detergent composition is introduced into a combustion chamber of the engine wherein the detergent composition can improve the performance of both a fuel composition and a lubricating oil of the engine. The detergent composition contains (A) a reaction product of a hydrocarbyl-substituted acylating agent and an amine, (B) a hydrocarbyl-substituted amine, (C) a Mannich reaction product, (D) a high molecular weight polyetheramine, or (E) a mixture thereof.
Abstract:
A fuel additive composition includes a reaction product of a succinic acylating agent and a polyamine having at least one condensable primary amine group where the reaction product has a ratio of the imide to amide infrared carbonyl absorption peak areas of about 1:0.0-0.6 and a water content of about 0.3 % or less by weight. The succinic acylating agent is prepared by thermal condensation of a highly reactive polyolefin with maleic anhydride or a reactive equivalent thereof. This fuel additive composition has a low chlorine content and is very effective in fuel compositions that include a normally liquid fuel in reducing deposits in the fuel intake system of an internal combustion engine.
Abstract:
A fuel composition exhibiting improved anti-static properties, comprises a liquid fuel which contains less than 500 parts per million by weight sulfur; 0.001 to 1 ppm of a hydrocarbyl monoamine or hydrocarbyl-substituted poly(alkyleneamine); and 10 to 500 ppm of at least one fatty acid containing 8 to 24 carbon atoms, or an ester thereof.
Abstract:
This invention relates to a process for reducing the level of pollutants in the exhaust of a diesel engine, comprising: operating said diesel engine using as the fuel a water-diesel fuel emulsion; and contacting the exhaust gas from said diesel engine with an after-treatment such as a filter.
