Genuine Quality Diesel Injector Repair Kit F 00R J02 177 F00RJ02177 Injector Parts Engine Parts Auto Parts

The injector repair kit is a set of parts used to repair injector failures. The following is a detailed introduction:

Components
Seals: Common ones include O-rings, gaskets, etc. O-rings are used to prevent fuel leakage and ensure the seal between the injector and the engine cylinder or fuel rail; gaskets can ensure the sealing between the internal components of the injector, such as the seal between the needle valve cavity and the injector body to prevent fuel leakage.

Needle valve assembly: It includes the needle valve and the needle valve body, which is a key component of the injector. The needle valve opens and closes the injection hole under the action of electromagnetic force or hydraulic pressure to control fuel injection. The needle valve assembly in the repair kit is usually precision-machined to ensure the matching accuracy with other parts of the injector, ensuring the accuracy and stability of fuel injection.

Spring and spring seat: The spring provides closing force for the needle valve, so that the needle valve can quickly close the injection hole when the power is off or the hydraulic pressure disappears. The spring seat is used to fix the spring to ensure its normal operation. After long-term use, the spring may be fatigued and deformed, affecting the performance of the injector. The spring and spring seat in the repair kit can replace the damaged parts in time and restore the normal operation of the injector.

Other parts: Some repair kits may also contain small parts such as snap rings, limit support rings, intermediate rings, and isolation rings. The snap ring is used to fix other parts inside the injector; the limit support ring can limit the movement stroke of the needle valve; the intermediate ring and isolation ring help optimize the fuel flow path and improve the uniformity and atomization effect of fuel injection.

Function and significance
Restore the performance of the injector: When the injector has faults such as dripping, poor atomization, and poor fuel injection, use the corresponding parts in the repair kit to replace it, which can repair the damaged or worn parts, restore the injector to normal working condition, and ensure that the fuel can be accurately and evenly sprayed into the engine combustion chamber, thereby improving the engine's power performance, fuel economy and emission performance.
Save maintenance costs: Compared with replacing the entire injector, repairs using a repair kit are usually less expensive. Because in many cases, the failure of the injector is only the damage of some parts. By replacing the specific parts in the repair kit, the problem can be solved without spending a high cost to buy a new injector assembly.

Environmental protection and energy saving: The repaired injector can better control the fuel injection, make the fuel burn more fully, reduce the emission of harmful substances in the exhaust gas, and is beneficial to environmental protection. At the same time, it can also avoid the waste of fuel caused by the failure of the injector and achieve the purpose of energy saving.

Scope of application
The injector repair kit is suitable for various types of injectors, including injectors for automobile engines (such as gasoline engines and diesel engines), as well as injectors used in some industrial equipment. Different types and brands of injectors require the use of repair kits of corresponding specifications and models. For example, the injector repair kit of the Volkswagen EA888 engine has its specific parts composition and specification requirements, which is suitable for models equipped with this engine such as Lingdu, the new Passat, and Touran L. When choosing an injector repair kit, you need to choose a suitable repair kit for repair according to the specific model and fault condition of the injector.
