How many kinds of carbon deposits are there on the engine?

The substance left in the nozzle, throttle, oil pipe, spark plug, cylinder head, inner wall and other parts due to insufficient combustion of gasoline in the cylinder, and then the black colloid produced by repeated high temperature of the engine is called carbon deposition.

One of the reasons for carbon deposition is that the fuel is not completely burned and adheres to various parts of the engine, which will form carbon deposition over time. The main function of additives is to drill into the pores of carbon deposits with strong surface activity, destroy its structure, gradually dissolve these carbon particles from the metal surface, and then burn them with fuel at high temperature and exhaust them through tail gas.

The increase of automobile carbon deposition will lead to insufficient combustion of the engine, which will lead to an increase in fuel consumption, and the automobile fault light will be on for a long time.

Methods to slow down the formation of carbon deposits:

1. Use high-quality fuel. Because the main components of carbon deposit are wax and gum deposits in fuel, the lower the gum content in fuel, the better. But we can't change the quality of fuel, but we can choose not to add cheap fuel from unknown sources.

2. Avoid driving at low speed for a long time. If necessary, you can pull up the speed regularly. The principle of removing carbon deposits by pulling high speed is to speed up the airflow, which can take away a small amount of carbon deposits that are not firmly attached. Increase the combustion temperature, so that some carbon deposits in the cylinder burn.

Harm of carbon deposition;

If the carbon deposits are not cleaned for a long time, the whole vehicle will run, and the internal passages of the engine will be blocked by carbon deposits, which will make the engine power worse and cause oil consumption, abnormal engine noise and unstable idle speed. , thus reducing the power of automobile engine, increasing fuel consumption, resulting in low combustion rate. If the carbon deposit is not cleaned up in time, it will not only cause some damage to the car, but also do great harm to the environment. Modern society pays attention to energy saving and emission reduction, and the exhaust emission must not exceed the standard, so we should pay attention to this problem.

Usually, use effective PNF fuel additive to clean the carbon deposit in the whole oil circuit every 5000 kilometers. If the carbon deposit is not cleaned for a long time, the whole vehicle will run, the internal passage of the engine will be blocked by carbon deposit, the fuel injection in the vehicle will be blocked, and the engine power will be worse, thus reducing the power of the automobile engine, increasing fuel consumption and causing low combustion rate.
