How often do you clean the throttle of the car injector?

The throttle is generally cleaned every 20,000 kilometers or so. Generally, clean the injector once every 2 years and 6W km. The reasons for cleaning and the hazards of not cleaning are as follows: Cleaning reasons: If you don't keep cleaning, the fuel consumption will increase and the power will decrease. It is best to clean it regularly. As one of the key components of EFI engine, the working quality of injector will seriously affect the performance of engine. The blockage of fuel injector will seriously affect the performance of automobile. The reason for the blockage is that carbon deposits in the engine are deposited on the fuel nozzle, or fuel impurities block the fuel nozzle channel. After the car runs for a period of time, the fuel system will form certain deposits. The formation of deposits is directly related to automobile fuel: firstly, because gasoline itself contains colloid and impurities, or dust and impurities brought in during storage and transportation, deposits similar to sludge accumulate in automobile fuel tanks and oil intake pipes; Secondly, the unstable components in gasoline react at a certain temperature to generate mucilage and resinous viscous substances. These viscous substances are located in the fuel nozzle, intake valve and other parts. When burned, the deposits will become hard carbon deposits. In addition, due to urban traffic congestion, cars are often at low speed and idle speed, which will aggravate the formation and accumulation of these deposits. Hazards of uncleanness: The deposits in the fuel system are very harmful. Deposits will block the needle valve and valve hole of injector, which will affect the working performance of precision parts of EFI system and lead to the decline of power performance. Deposits will form carbon deposits on the intake valve, which will lead to its lax closure, unstable engine idle speed, increased fuel consumption and worsening exhaust emissions; Deposits will form hard carbon deposits on the piston crown and cylinder head. Due to the large thermal capacity and poor thermal conductivity of carbon deposit, it is easy to cause engine knocking and other faults; In addition, it will shorten the life of the three-way catalytic converter. The working quality of the fuel injector plays a vital role in the power of each engine. Because the fuel is not good and the injector is not easy to use, the carbon deposition in the cylinder is serious; Accelerated wear of cylinder and piston ring leads to unstable idle speed, increased fuel consumption, weak acceleration, difficult start-up and excessive emissions, which will completely block the injector and damage the engine.
