How to remove carbon deposit from diesel engine

Mechanical method is a method to remove carbon deposits and oil stains with wire brush, scraper, bamboo chips or emery cloth. Special brushes and scrapers can be made according to the shape of the parts to be cleaned: for example, carbon deposits and oil stains around the nozzle holes of the fuel injector can be cleaned with a fine copper wire brush; The carbon deposit in the pressure chamber can be scraped off by inserting a special through needle made of copper wire; Carbon deposits and oil stains on valve guides and valve seats can be removed with cylindrical metal brushes.

The mechanical carbon removal efficiency is low, the quality is poor, some parts are difficult to scrape clean, leaving many small scratches, which become the growth point of new carbon deposition and increase the roughness of parts. Therefore, this method is generally not suitable for parts with high precision.

Failure caused by carbon deposition:

For example, problems such as idle jitter, difficult start-up, excessive idle speed and excessive exhaust volume must be cleaned up. Conventional vehicles must also be cleaned for carbon deposits once every six months or 654.38+0000 kilometers. You can use some disassembly-free cleaning agents for cleaning.

The formation of automobile carbon deposit is due to some impurities in gasoline. If you use gasoline with higher cleanliness, there will be less carbon deposition in the car. If you use some car cleaner, you can activate carbon particles formed on the metal surface. Get into the good habit of using the car. You need to warm up the vehicle before each start, which can also reduce the generation of carbon deposits.
