What items does carbon deposit cleaning include?

Hello! There are many ways to clean up carbon deposits, and the targeted parts are different.

It mainly includes three types of carbon deposit cleaning scope, namely:

Cleaning of carbon deposit in throttle and injector.

Removal of carbon deposit in intake manifold.

Cleaning of carbon deposit in cylinder (combustion chamber).

There are also various specific methods to clean up carbon deposits, specifically:

Disassembly and cleaning method of engine. Commonly known as "mining", as the name implies, is to completely dismember the engine and then carefully clean all the components in the engine. This method takes a long time and has the most thorough cleaning effect. In addition to carbon deposition cleaning, all parts inside the engine can also be thoroughly cleaned. However, this method is rarely used in practice because of expensive working hours and long time consumption.

Walnut sandblasting cleaning method. Walnut shells become tiny particles after being fully broken, which is called "walnut sand". Using high-pressure and high-speed airflow as the carrier, carrying a large amount of walnut sand to impact the specific area inside the engine, and cleaning up the carbon deposit under the impact of high-speed walnut sand. This is a purely physical method to clean up carbon deposits, which is increasingly used at present, but this method can only deal with carbon deposits in water intake.

Chemical cleaning of hanging bottles. Using high-concentration cleaning agent, which is sucked into the intake manifold under the action of engine intake vacuum, can clean the carbon deposit in the intake manifold and combustion chamber, but it is ineffective for the carbon deposit in the throttle.

Special cleaning agent for fuel oil blending. Using low concentration cleaning agent, with the fuel entering the engine, the carbon deposit in the oil circuit and cylinder can be cleaned, but it has no effect on the carbon deposit in the throttle valve and the carbon deposit in the intake manifold.
