What is the best method to remove engine carbon deposits?
1 Answers
Better methods for removing engine carbon deposits are as follows: 1. Additive cleaning (fuel additive): Additive cleaning involves directly adding a cleaning agent into the fuel tank to mix with the fuel. When the vehicle is started, the cleaning agent enters the combustion chamber along with the fuel, where it cleans the carbon deposits inside the engine to a certain extent. 2. Drip bottle cleaning: Drip bottle cleaning, also known as no-disassembly cleaning, is a cleaning method currently promoted by 4S shops. This method uses a drip bottle to introduce the cleaning agent into the engine's intake pipe, where it is sucked into the combustion chamber along with the intake airflow. During this process, the cleaning agent cleans the carbon deposits in the engine's intake tract and combustion chamber. 3. Disassembly cleaning: Disassembly cleaning involves removing parts of the engine with carbon deposits for cleaning. Although this method provides the best cleaning effect, it is labor-intensive and time-consuming, so most 4S shops do not offer disassembly cleaning services.
