How to effectively remove carbon deposits

In fact, the "hanging bottle" is filled with a cleaning agent that has been pressurized and atomized. The cleaning agent is pumped into the air inlet to react with the carbon deposits in the throttle valve, fuel injector and other parts, and then the cleaned carbon deposits are blown out of the engine by using the high speed of the engine.

It is worth noting that the "hanging bottle" will discharge the cleaned carbon deposit through the exhaust system, but if the carbon deposit is very serious, it will cause blockage or even damage to the three-way catalytic system.

Use detergent

The cleaning agent is poured into a machine and sprayed into the combustion chamber by the machine under pressure, so that the cleaning agent reacts with the carbon deposit to dissolve, and then the waste liquid is pumped out.

It should also be noted that if the carbon deposition is very serious, the combustion chamber may be damaged if the falling large pieces of carbon deposition cannot be completely sucked out.

3. Fuel additives

Long-term use of clean fuel additives, although not as thorough as advertised, still has certain effects, especially for non-direct injection vehicles.

Nowadays, there are many effect diagrams circulating on the Internet to clean up carbon deposits, which are actually exaggerated. Although these things have a certain effect, they are not so exaggerated, depending on the quality and performance of the cleaning agent used.

Diagnostic method of carbon deposition

It is very simple to diagnose carbon deposit in intake pipe in automobile maintenance. As long as the throttle is removed, the degree of carbon deposition can be clearly seen. However, the diagnosis of valve carbon deposit has always been a difficult problem. Generally speaking, there are two diagnostic methods in professional repair shops.

1, disintegration method

That is, take the engine apart and check whether there is carbon deposit. This is intuitive, but time-consuming and laborious, and every time any part is disassembled, its performance will be affected more or less and its service life will be shortened.

2. Endoscopy

Remove the spark plug or nozzle and observe the degree of carbon deposition in the valve with an endoscope. This method is very convenient, but the cost of endoscope is not small, and it is not widely used in maintenance, so not all maintenance enterprises are equipped with this equipment.
