How often does it take to clean the carbon deposits, and how often does it take to clean the throttl

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:

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 in general. After 1-20,000 kilometers, the performance will be affected, and it is best to do a disassembly-free cleaning every 5,000-10,000 kilometers. The symptoms after the production of carbon deposits are as follows:

1. It is not easy to start when the cold car is ignited many times, and the hot car is normal. 2. The engine idle speed is unstable, high and low. 3. When filling the air oil, I feel that the acceleration is not smooth, and there is a stuffy phenomenon.

It is recommended to clean the valve of the leading joint hole once every 20,000 kilometers. After the gas enters the intake pipe, it will mix with gasoline to form a combustible mixture, so that the work of combustion is done. The role of the throttle:

1. The throttle valve is a controllable valve that controls the air to enter the divergent celery machine, and the gas will be mixed with gasoline to become a combustible mixture after entering the intake pipe, so as to burn to form work;

2. It is connected to the air filter and the engine block, which is known as the throat of the automobile engine. The throttle four-stroke gasoline engine is roughly like this;

3. The throttle valve is one of the most important components of the engine system of today's EFI vehicle, the upper part of which is the air filter air grid, and the lower part is the engine block, which is the throat of the automobile engine.
