How to Clean Carbon Deposits in the Combustion Chamber?
1 Answers
Methods for cleaning carbon deposits in the combustion chamber are as follows: 1. Mechanical Method: This involves using steel wire brushes, scrapers, bamboo chips, or sandpaper to remove carbon deposits and oil stains. Special brushes and scrapers can be customized according to the shape of the parts to be cleaned. For example, fine copper wire brushes can be used to clean carbon deposits and oil stains around the injector nozzles; a specialized copper wire needle can be inserted into the pressure chamber to scrape off carbon deposits; cylindrical metal brushes can be used to remove carbon deposits and oil stains from valve guides and valve seats. 2. Walnut Shell Blasting Method: This method uses high-speed airflow to blast crushed walnut, peach, or apricot shell particles onto the part surface to remove carbon deposits and oil stains. This method is highly efficient and thorough, but it requires specialized equipment to generate high-speed airflow, making it relatively costly and thus not widely adopted. 3. Chemical Method: This involves using a chemical solvent or carbon remover to soften the carbon deposits and oil stains on the part surface, causing them to lose their adhesion to the metal, and then removing the softened carbon deposits. This method is highly efficient, effective, and less likely to damage the part surface. 4. Adding Diesel Additives: Most additives contain chemical components that can clean carbon deposits and oil stains. When the vehicle's condition is poor, adding the additive twice can effectively clean carbon deposits and oil stains in the engine combustion chamber, intake manifold, and fuel system, while also improving fuel quality.
