Is it necessary to clean the fuel injector?

Of course, cleaning the nozzle is necessary: 1. It is estimated that many people think that the nozzle is simply fuel injection. After the car runs for a period of time, the fuel system will form certain deposits; 2. The formation of deposits is directly related to automobile fuel: firstly, because gasoline itself contains colloid, impurities or dust and impurities brought in during storage and transportation, deposits similar to oil sludge are formed in automobile fuel tanks, oil intake pipes and other parts over time; 3. Second, unstable components in gasoline react at a certain temperature to form mucilage and resinous sticky substances. When these viscous substances burn in the nozzle, intake valve and other parts, the deposits will become hard carbon deposits; 4. If the fuel injector is not cleaned for a long time, there may be accelerated wear of the automobile engine, unstable idle speed, rising fuel consumption, weak acceleration, and difficult start-up. However, the time interval of clean fuel injection depends on the daily environment and oil products of the owner. Generally speaking, the frequency of cleaning automobile oil circuit is every 30,000-40,000 kilometers.
