How to maintain the fuel system

Hazards of uncleaned fuel system

If the fuel system is not cleaned, carbon deposits and deposits will block the needle valve and valve hole of the injector, affecting the performance of precision parts of the injection system, leading to poor fuel injection, poor atomization and decreased power performance. Carbon deposition on piston crown and cylinder head may easily lead to local overheating of combustion chamber and gasoline preheating, which may lead to engine knocking and other failures.

Maintenance method of fuel system

(1) Add high-quality fuel system cleaner regularly. It can effectively remove gum, carbon deposits and deposits in the combustion chamber, intake and exhaust valves, fuel nozzles and fuel pipelines during vehicle driving, and keep all parts of the fuel system clean.

(2) Regular use of high-quality cleaning agent for injector system can remove carbon deposit in injector and eliminate engine jitter, hysteresis, poor atomization and poor acceleration. So that the oil-gas mixing ratio is more accurate.

(3) Regularly clean the throttle system with high-quality throttle or intake system cleaning agent.

Generally, maintain the fuel system every 50,000 kilometers.

Because gasoline contains certain impurities, it will produce certain carbon deposits in the combustion chamber during the combustion process, which will affect the combustion effect and power performance for a long time, resulting in high fuel consumption, and gasoline filter elements will also produce impurities, which need to be replaced regularly.

Under normal circumstances, it is recommended to add a protective agent when cleaning the fuel system at the 4S point of 50,000 kilometers for new cars. This varies from person to person, some big brands can consider adding it, and unknown small brands should not be used.
