Cleaning agent capable of cleaning carbon deposition of engine

Abstract

The invention discloses a cleaning agent capable of cleaning carbon deposition of an engine. The cleaning agent comprises the following components by mass percentage: 5-10% of polyisobutylene succinimide, 89-94% of surface-active agent, 0.01-0.02% of nano CeO2 and 0.05-0.2% of anti-sinking agent. The cleaning agent can effectively clean the deposition of an oil way and an air damper; the idling shaking of the engine is eliminated; noises are reduced; the power is improved; and the working stability of the engine is improved.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent capable of cleaning engine carbon deposits, and belongs to the field of polymer chemistry. Background technique [0002] After the car has been running for a period of time, a certain amount of deposits will form in the fuel system. The formation of deposits is related to the fuel of the car. The deposits mainly come from the following two aspects. Deposited in the carburetor, intake pipe, intake valve, combustion chamber to form colloid) or dust, impurities, etc. brought in during storage and transportation, accumulate over time in the automotive fuel tank, oil intake pipe, carburetor and other parts to form sludge-like Deposits; on the other hand, unstable components such as olefins in gasoline undergo oxidation and polymerization reactions at a certain temperature to form colloidal and resinous viscous substances. These viscous deposits in the fuel injectors, intake valve...

AI Technical Summary

Problems solved by technology

[0004] 1. When carbon deposits adhere to the intake and exhaust valves, the intake and exhaust valves are not closed tightly enough to cause air leakage, and the pressure in the engine cylinder drops. The direct result is that the engine is difficult to activate and shakes at idle speed; In the section of the combustion chamber, carbon deposits can absorb a certain amount of mixed gas, thereby reducing engine power;

[0005] 2. When the carbon deposit adheres to the cylinder and the top of the piston, it will reduce the volume (space) of the combustion chamber and increase the compression ratio of the cylinder. When the compression ratio is too high, it will cause early combustion of the engine (solid engine knock) and reduce the engine power ;

[0007] 4. When carbon deposits are formed between the piston rings, the piston rings will be easily stuck, causing engine oil and straining the cylinder wall

[0008] 5. When the carbon deposit adheres to the oxygen sensor, the oxygen sensor cannot correctly perceive the exhaust gas condition, and cannot correctly adjust the air-fuel ratio, so that the engine exhaust gas exceeds the standard

[0009] 6. When carbon deposits are formed inside the intake manifold, the interior becomes rougher, affecting the formation and concentration of combustible mixture

[0010] As mentioned above, the carbon deposit in the engine will bring great harm to the vehicle. Therefore, over the years, the chemical industry has tried to study various methods to clean the deposits in the fuel system. The early method is to remove the fuel system of the car. After cleaning manually or soaking with strong acid or strong alkali, this method not only has a long cleaning cycle and high cost, but also because the car is a precision assembled product, cleaning after disassembly will often cause corrosion to the metal in the fuel system and cause damage. The precise fit of the parts themselves; in recent years, a variety of automotive fuel system cleaning agents have appeared in this field, usually composed of small molecule alcohols, alkylamines, surfactants, alcohol ethers and other components, these components On the one hand, its own chemical stability is poor, on the other hand, these components often have a certain degree of gasification during actual use, making them unable to contact with carbon deposits, reducing the cleaning effect
