Product Description

Machine parts Injector assembly
The injector assembly ‌ plays a vital role in the fuel injection system, its main functions include:

‌1. Press and mix air and fuel ‌ : Machinery Parts The injector is responsible for converting liquid fuel into a mist, mixing it with air, and then injecting the mixture precisely into the cylinders of the engine, which is the core component of the air pump power system ‌
‌2. Control the fuel supply of the engine ‌ : by the control of the electromagnetic coil, Electrical accessories The injector can precisely adjust the injection amount and injection time of fuel, so as to control the fuel supply of the engine, and ensure the normal operation of the engine under different working conditions ‌
‌3. Affect the performance of the engine ‌ : the performance of the injector directly affects the power, economy and emission performance of the engine. If the injector fails or performance deteriorates, it may lead to reduced engine power, increased fuel consumption, and worsening emissions ‌
The composition and working principle of the injector assembly
‌Valve body, needle valve, return spring, armature, solenoid, oil filter and harness connector ‌ : Chassis Parts Work together to complete fuel pressing, mixing and injection tasks ‌

‌electromagnet assembly ‌ : including coil, core, chamber, electric connector and tight cap and other parts, generate electromagnetic force when powered on, drive the armature tray to move, control the nozzle needle valve ‌5.

‌ armature assembly ‌ : composed of a bit core, armature disc, guide mechanism, buffer gasket, valve ball and support seat, which moves up and down under the action of electromagnetic force to realize injection control ‌.

‌ valve assembly ‌ : composed of valve seat and ball valve, with minimal clearance, responsible for oil return control ‌.

‌ injector body ‌ : contains high and low pressure oil passage, withstand the working pressure ‌.

‌ nozzle couple ‌ : composed of a needle valve and a needle body, responsible for the precise injection of fuel into the combustion chamber ‌.

Fuel injector assembly maintenance and troubleshooting methods

In order to ensure the normal operation of the fuel injector, regular inspection and maintenance are required:

Check the solenoid and circuit connection of the injector ‌ to ensure that the power is normal.

‌Clean the oil inlet filter ‌ to prevent blockage of impurities.

‌Check the fit of needle valve and valve body ‌ to ensure that the seal is good.

‌Replace damaged or aged parts ‌ regularly, such as return springs and electromagnetic coils.

Through these maintenance measures, the service life of the injector can be extended to ensure its stable performance.
