[0002] The automobile fuel injector is one of the key components in the engine fuel system. Its main function is to inject gasoline or diesel into the engine cylinder in a high-pressure form to achieve combustion and drive the engine to work.

[0003] The fuel injector is a key component of the engine fuel injection system, responsible for efficiently injecting fuel into the engine combustion chamber. If the fuel injector is clogged or the spray is uneven, it will lead to incomplete combustion, reduced power, increased fuel consumption and even substandard emissions.

[0004] The inside of the fuel injector will accumulate sediment and carbon scale due to long-term use, which will affect the normal operation of the fuel injector. If the fuel injector does not work properly, it may cause unstable engine operation or even failure. Regular cleaning and testing can prevent engine performance degradation or failure caused by fuel injector problems.

[0005] The automobile fuel injector cleaning and testing instrument is a device specially used to detect and clean the engine fuel injectors. Through cleaning and testing, the service life of the fuel injectors can be extended and the working effect of the engine can be optimized.
