Genuine Quality Diesel Injector Repair Kits 891811(C11/C13/C15/C18) Injector Parts Engine Parts Auto Parts

Function
When the injector is worn, poorly sealed, or has poor fuel injection, the corresponding accessories in the repair kit can be used to replace it, which can restore the normal working performance of the injector and avoid the high cost of directly replacing the entire injector. It can also improve maintenance efficiency and save maintenance time.

Common accessories
Seals: such as O-rings, sealing rings, etc. O-rings are used to prevent fuel leakage and ensure the seal between the injector and the fuel line and the engine combustion chamber; the sealing ring can ensure the sealing between the internal components of the injector, prevent fuel from leaking inside, and affect the injection pressure and injection accuracy.

Springs and related parts: including injector springs, spring seats, etc. The function of the spring is to quickly close the needle valve after the injection is completed, and the spring seat is used to fix the spring to ensure its normal operation. If the spring elasticity is weakened or damaged, it will cause problems such as abnormal injection pressure and inaccurate injection time. Replacing the spring and related parts can solve such problems.
Needle valve and valve seat: The needle valve and valve seat are key components of the injector, and their matching accuracy directly affects the injection quality. After long-term use, the needle valve and valve seat may be worn, pulled or carbonized, resulting in nozzle dripping, poor atomization and other faults. The needle valve and valve seat in the repair kit are usually precision-machined, and replacement can restore the normal injection function of the injector.
Other parts: Some repair kits may also contain parts such as snap rings, intermediate rings, isolation rings, and limit support rings. The snap ring is used to fix other parts to prevent them from loosening; the intermediate ring, isolation ring, and limit support ring play the role of auxiliary positioning, isolation, and support to ensure the normal installation and working position of the various parts of the injector and the overall performance of the injector.

Scope of application
Different types and models of injectors require corresponding repair kits. For example, injectors of different brands such as Bosch and Delphi, as well as injectors suitable for different models and engine models, may have different specifications and accessory compositions of their repair kits. When choosing a repair kit, it must be accurately matched according to the specific brand, model, and vehicle information of the injector to ensure that the repair kit can adapt to and effectively repair the injector fault.

Brand and quality
There are many brands of injector repair kits on the market. Some well-known brands such as Bosch and Delphi use high-quality materials and advanced manufacturing processes in their repair kits, which are reliable and can better restore the performance of the injector. However, some non-well-known brands or low-quality repair kits may have problems such as insufficient precision of accessories and poor material quality. After use, they may not completely solve the injector failure, and may even cause further damage to the injector, affecting the normal operation of the engine. Therefore, when choosing a repair kit, it is recommended to give priority to well-known brands and products with guaranteed quality.
