Fuel system carbon deposit undisassembly abluent of diesel engine

Abstract

The invention relates to a fuel system carbon deposit undisassembly abluent of a diesel engine. The abluent can effectively moisten and disperse oil dirt, colloid substance and carbon deposit which are attached to a fuel system of a gas engine when the gas engine starts up, and also can reduce the burning point of the carbon deposit to enable the carbon deposit to burn. When in use, the abluent can be added in the fuel according to a certain proportion. The abluent has the functions of saving fuel, reducing consumption, purifying tail gas, enhancing power and preventing attachment of dirt and long-time maintenance. The component of the formula of the abluent is a compound taking organic polymer as a base solution, and the abluent is prepared by mixing a dispersant agent, a decarbonizer, an oxygenate, a carbon burning accelerant and a carbon burning point depressant in a compound way.

Description

technical field [0001] The non-disintegrating cleaning agent for diesel fuel system carbon deposits of the present invention can clean the carbon deposits in the engine fuel system, combustion chamber and other parts during engine operation, and remove colloid and carbon deposits in valves, oil delivery pipes, fuel tanks and other parts. Effectively remove various dirt and deposits (colloid, carbon deposits, sludge, etc.) attached to diesel engine oil circuit components, restore engine power, prolong the service life of fuel system components, improve the oil-gas mixing ratio, and make combustion more complete , reduce fuel consumption and emissions, increase power, so that the cleaned engine has the effect of saving energy and reducing pollution. Background technique [0002] At present, the quality of crude oil used by my country's oil refining enterprises is not high, and the catalytic hydrogenation technology in the refining process has not been widely used. The main com...

Problems solved by technology

[0005] Most of the existing energy-saving detergents use long-chain oil-soluble surfactants, which are not easy to decompose at higher temperatures, and can peptize the carbon deposits on the fuel injectors and intake valves into the carrying oil and flow to them. Combustion or generation of carbon deposits in the combustion chamber, so whether it is gasoline or diesel fuel, the level that can be achieved in the past is to clean and clean the fuel injectors and intake valves, which increases the carbon deposits in the combustion chamber, and the accumulation in the combustion chamber Carbon has little effect on the combustion performance of new fuels. Therefore, in the past, the index of detergents was set as the qualification standard of not increasing 40% carbon deposits, which means that qualified detergents in the past all increased carbon deposits in the combustion chamber.

[0006] The existing patent uses aromatic compounds with relatively strong polarity and good solubility for organic polymers as a fuel-based cleaning agent. A certain dissolution effect, but under the working conditions of the engine, the temperature in the combustion chamber is high, such substances are easy to vaporize, enter the gas phase from the liquid phase, and no longer contact with the scale substances, and the combustion of the substances themselves is not complete, and the combustion Carbon particles and carbon deposits are easily generated indoors, and the colloidal carbon deposits in the fuel injector are brought into the combustion chamber to increase the carbon deposits in the combustion chamber

[0007] Some microemulsion cleaning agents have poor storage stability during use, and are easy to separate oil and water before the injector, resulting in increased wear of this part, and the electrolyte solution in it is easy to corrode metal parts

[0008] Some patents use cleansing and dispersing agents in lubricating oils such as calcium petroleum sulfonate, barium, magnesium, and alkyl salicylates, which can dissolve carbon deposits in lubricating oils, but such additives are used in fuel cleaning agents, which will It leads to incomplete atomization and combustion, and the increase of carbon deposits and other non-carbon deposits in the combustion chamber, which is not suitable for use as a fuel cleaning agent.

[0009] Some patents use surfactants that can work effectively at room temperature, or some small molecular weight alcohols, or some organic amines cannot effectively remove carbon deposits
