Carbon deposit scavenging agent for combustion chamber and spark plug, and preparation method of the same

Abstract

The invention discloses a carbon deposit scavenging agent for a combustion chamber and a spark plug, and a preparation method of the same. Water is taken as a medium for the scavenging agent, so that the scavenging agent is safe and environmentally friendly, and produces no secondary pollution. The scavenging agent comprises the following components: 2-10 wt% of non-ionic polyethenoxy ether surfactant; 2-8 wt% of anionic fatty acid salt surfactant; 5-20 wt% of alcohol, alcohol ether and ketone organic solvent; 0.5-5 wt% of inorganic base; 0-2 wt% of buffer; 0-3 wt% of metal corrosion inhibitor; and 50-91.5 wt% of deionized water. The composite surfactant used in the scavenging agent can emulsify the carbon deposit effectively so as to soften, loosen and deform the inflexible carbon deposit, and simultaneously can improve the seepage force of the scavenging agent; the alcohol organic solvent further dissolves the carbon deposit; the inorganic base decomposes oil and fat compounds; the buffer maintains certain basicity; and the corrosion inhibitor reduces corrosion on metallic elements in a cleaning process. The carbon deposit scavenging agent provided by the invention can eliminate the carbon deposit adhered to the top of a combustion chamber piston, an intake valve, a vent valve, the spark plug and the inner wall of a spark plug hole, quickly and efficiently. The scavenging agent provided by the invention is completely prepared by environmental materials, and is free of the components, such as aromatic hydrocarbon, halogenated hydrocarbon and the like, which are harmful to human body, so that the scavenging agent is safe for human body and has no pollution to the environment and the atmosphere.

Description

technical field [0001] The invention relates to a carbon deposit scavenger for combustion chambers and spark plugs. The scavenger uses water as a medium, is safe and environmentally friendly, and has no re-pollution. Background technique [0002] Coke deposits: unburned carbon particles or grease deposits deposited on hot channel components from thermal decomposition of fuel, commonly known as carbon deposits. [0003] When the engine is working normally, the mixed gas (air, atomized gasoline, a small amount of oil vapor) in the combustion chamber cannot be burned uniformly and fully, resulting in soot and burnt particles of lubricating oil. When the engine continues to run, these combustion residues are further oxidized and become colloids, which are firmly adhered to the top of the piston, the piston ring, the back of the valve, the inner surface of the intake pipe, the throttle body and the combustion chamber, etc. Under the repeated action of high temperature, colloids ...

Problems solved by technology

The disassembly and removal method is to disassemble the engine and remove the carbon deposits from the parts with carbon deposits mechanically. This method is labor-intensive and time-consuming, and the parts are easily damaged.
