The residue of substances in the fuel injector, throttle, oil pipeline, spark plug, cylinder head, inner wall and other parts caused by insufficient combustion of gasoline in the cylinder, and then the black gum produced by the repeated high temperature action of the engine is called carbon deposit.
One of the reasons for carbon deposition is that the fuel is not completely burned and adheres to various parts of the engine, which can form carbon deposits over time. The main function of additives is to drill into the pores of carbon deposits with strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through the exhaust gas after burning with the fuel at high temperature.
The increase in carbon deposits in the car will lead to insufficient combustion of the engine, resulting in an increase in fuel consumption and a long time when the car failure light is on.
Ways to slow down the formation of carbon deposits:
1.Use high-quality fuel. Because the main components of carbon deposits are wax and colloidal deposition in the fuel, the lower the colloidal content in the fuel, the better. But we can't change the quality of the fuel, but we can choose not to add unidentified cheap fuel.
2.Avoid driving at low speeds for long periods of time. If necessary, the high speed can be pulled at a regular time. The principle of removing carbon deposits at a high speed is to speed up the airflow, which can carry away a small amount of carbon deposits that are not firmly attached. The combustion temperature is increased so that part of the carbon deposits in the cylinder are burned.
carbon deposition hazards; If the carbon deposit is not cleaned for a long time, the operation of the whole vehicle will be caused, the internal channel of the engine will be blocked by carbon deposits, the engine power will become worse, and the occurrence of fuel consumption, abnormal engine noise, and unstable idle speed will occur, thereby reducing the power of the automobile engine, increasing fuel consumption, and causing the combustion rate to be too low. If you do not clean up the carbon deposit in time, it will not only cause a certain degree of harm to the car, but also the harm to the environment, modern society pays attention to energy conservation and emission reduction, and exhaust emissions must not exceed the standard, so we should pay attention to this problem.
Usually 5000 kilometers with effective PNF fuel additives to clean the overall oil circuit carbon deposits, a long time not to clean up the carbon deposits will cause the operation of the whole vehicle, so that the internal channel of the engine is blocked by carbon deposits, the internal fuel injection of the car is not smooth, so that the engine power becomes poor, thereby reducing the power of the car engine, increasing fuel consumption, and the combustion rate is too low.

Carbon deposits at the spark plug location need to be cleaned regularly. Due to the long-term use of the spark plug, the deposits on the spark plug will become thicker and thicker, which will eventually cause the spark plug to not work properly; At the same time, due to excessive carbon deposition in the combustion chamber of the car, the temperature in the combustion chamber will be too high, and the spark plug will melt and ablate the electrodes. If the spark plug fails, the car will have unstable idling, shaking, and weak acceleration.
The first method is to remove the spark plug and use a blade to scrape all the carbon deposits on the surface of the spark plug. Then polish it with fine sandpaper.
The second method is to disassemble the spark plug and spray it with the relevant cleaning agent, which can generally remove the dirt on the surface of the spark plug with carburetor cleaning agent.
The third method, if the dirt on the surface of the spark plug cannot be removed normally, it can be soaked in oxalic acid, cleaned or soaked with gasoline, and the carbon deposits on the surface of the spark plug can be removed by soaking for 2 to 3 hours.
Fourth, if the carbon in the surface area of the spark plug is particularly serious and the gap is too large, then there is no need to clean it, and the spark plug can only be replaced with a new one.

Summary. The cleaning agent of the spark plug hole with the valve not closed will flow into the cylinder, and incomplete combustion will cause the engine to work abnormally, and even cause **. At the same time, cleaners can damage a car's engine and emissions system, leading to more serious consequences.
Therefore, before cleaning the valves and spark plugs, be sure to close the valves and operate according to the instructions to avoid unnecessary losses.
Can you elaborate on that a little bit more?

Do spark plug carbon deposits need to be cleaned up? Do spark plug carbon deposits need to be cleaned up? Spark plug carbon deposits definitely need to be cleaned up, here's how:
1. Wipe the dust and oil around the spark plug first, and then take the spark plug off the cylinder of the engine, be sure to wipe it carefully to prevent oil and dust from entering the cylinder, and cover the cylinder with things after going down; 2. After removing the spark plug, first use a knife or waste hacksaw blade to scrape off the dirt and carbon deposits on the spark plug (if the dirt and carbon deposits are not easy to scrape off, you can burn the spark plug with fire first.) Be careful not to use strong fires to avoid burning the insulation of the spark plugs). When the dirt and carbon deposits are cleaned up, clean and dry them with gasoline; 3. Before reinstalling the spark plug, check the electrode clearance of the spark plug, which should meet the specified value of the spark plug gap of the corresponding model.
If the gap between the spark plug electrodes does not meet the requirements, the side electrodes of the spark plug can be adjusted with wooden utensils, and the middle electrode of the spark plug should not be moved in general, so as not to damage the insulator of the spark plug. @2019

When replacing the spark plugs, there is no need to clean the throttle. They are different systems. The spark plug is the ignition system, and the throttle is the intake system.
The spark plug is an important part of the ignition system of a gasoline engine. It introduces high-voltage electricity into the combustion chamber, causing it to skip the electrode gap and generate a spark that ignites the combustible mixture in the cylinder.
Replacement procedure for spark stopan chains:
Open the hood, lift the cover plate of the engine, remove the high-voltage branch line, and mark the position of each cylinder to avoid confusion.
Remove the spark plug with the spark plug sleeve in turn. When disassembling, pay attention to check for leaves, dust, etc. Outside, be sure to clean up.
Place the new spark plug into the spark plug hole, turn it a few times by hand and tighten it with the sleeve.
Install the removed high-voltage spurs in the ignition order and fasten the covers.
Spark plug replacement cycle:
Under normal maintenance, it should be replaced after 4 60,000 kilometers. But there will be differences due to different brands and engines. It is recommended to follow the user manual.
Millions of car purchase subsidies.

Why is carbon deposited generated? This is because the fuel itself contains gum, impurities, dust, moisture, etc., which accumulate over time to form sludge and other deposits in the fuel tank, oil inlet pipe, etc.; Secondly, due to the oxidation and polymerization reaction of unstable components such as olefins in gasoline at high temperatures, colloidal and resinous viscous substances are formed, which stay in the fuel injector, air intake valve and other parts, and the deposits will become hard carbon deposits when burned. >>>More
