Carbon deposit cleaning agent for motor vehicle combustion system

Abstract

The invention discloses a carbon deposit cleaning agent for a motor vehicle combustion system. The carbon deposit cleaning agent is characterized by comprising three components, wherein the component 1 is prepared from the following raw materials in percentage by weight: 5% of sodium silicate, 2.3% of sodium tripolyphosphate, 1.2% of sodium carbonate, 5% of sodium gluconate and 10% of deionized water, the component 2 is prepared from the following raw materials in percentage by weight: 10% of butyl cellosolve, 5% of butanol, 2.8% of triethanolamine and 10% of deionized water, and the component 3 is prepared from the following raw materials in percentage by weight: 1.5% of EDTA-2Na, 2% of AEO-9 and 45.2% of deionized water. High-temperature carbon deposit, high-temperature greasy filth and the like on a combustion chamber, an air inlet branch, an exhaust branch, an oil spray nozzle, a sparking plug and an air inlet / exhaust valve of a combustion system of an existing motor vehicle can be effectively softened and dissolved by the carbon deposit cleaning agent and cleaned by engine carbon deposit cleaning equipment, so that the engine operating condition of the motor vehicle in use can be effectively recovered and the effects of saving fuel oil and reducing exhaust gas emission are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a carbon deposit cleaning agent for a motor vehicle combustion system. technical background [0002] The combustion chamber, intake branch pipe, exhaust branch pipe, fuel injector, spark plug, and intake (exhaust) valve of the combustion system of a motor vehicle during use are most likely to produce high-temperature carbon deposits and high-temperature sludge. During the working process of the engine, unsaturated olefins and colloids in the fuel are a coke-like substance produced at high temperature, or adhere to the machine parts when the fuel cannot be completely burned. [0003] For example: determined by the control characteristics of the EFI engine, every time the cylinder works, it injects fuel first and then ignites. When we turn off the engine, the ignition is cut off immediately, but the gasoline injected by this working cycle cannot be controlled. Recycling ...

Problems solved by technology

[0004] Since the structure of carbon deposits is similar to that of a sponge, when the carbon deposits are formed on the valve, a part of the fuel injected into the cylinder will be absorbed each time, making the concentration of the mixture that actually enters the cylinder thinner, resulting in poor engine operation, difficulty in starting, and poor idle speed. Stability, poor acceleration, sudden refueling and tempering, excessive exhaust gas, increased fuel consumption and other abnormal phenomena

If it is more serious, it will cause the valve to not close tightly, so that a certain cylinder will not work completely due to lack of cylinder pressure, and even the valve will not return due to adhesion.

At this time, the valve and the piston will produce movement interference, which will eventually damage the engine.
