Components
Seals: such as O-rings and gaskets, which are used to prevent fuel leakage and ensure the sealing performance between the injector and the engine cylinder block and the internal oil circuit. For example, the Volkswagen EA888 engine injector repair kit contains combustion chamber sealing rings, isolation rings, O-rings and limit support rings. These seals ensure the sealing inside the engine and prevent fuel and gas leakage.
Valve assembly: including ball valves, valve cores, valve seats, etc., are key components for controlling fuel injection. They determine parameters such as the timing, amount and pressure of injection. Taking the Bosch common rail injector repair kit as an example, the valve assembly is usually an important component. The precise valve assembly can ensure that the injector can accurately control fuel injection under high pressure.
Spring components: such as needle valve springs, armature springs, etc., provide elastic force for the valve core and other components of the injector, so that it can open and close at the right time to achieve normal injection function.
Other parts: may also include intermediate rings, retaining rings, limit support rings, etc. Different repair kits vary according to the specific structure and model of the injector. For example, some repair kits will have retaining rings for fixing the injector nozzles, as well as limit support rings for supporting and positioning.

Function
Restore injector performance: After long-term use, the injector may have problems such as poor injection, dripping, and uneven injection, which will affect the engine's power, fuel consumption and emission performance. The parts in the repair kit can replace the worn or damaged original parts, restore the injector to a good working condition, ensure that the fuel can be accurately and evenly injected into the engine combustion chamber, thereby improving the overall performance of the engine.
Extend the service life of the injector: Timely replacement of damaged parts can avoid further deterioration of the problem and prevent the entire injector from being scrapped due to local failures, thereby extending the service life of the injector and reducing maintenance costs.
Improve maintenance efficiency: The repair kit brings together the main parts required for maintenance, which is convenient for maintenance personnel to use, reduces the time and effort of finding and purchasing individual parts, improves the efficiency of maintenance work, and enables vehicles or equipment to resume operation faster.

Selection and use precautions
Matching the injector model: The injector structure and parameters of different models and engine models are different, so it is necessary to choose a repair kit that accurately matches the injector. When purchasing a repair kit, accurately provide the brand, model, engine model and injector information of the vehicle to ensure that the repair kit can be applied.
Choose high-quality products: The quality of injector repair kits on the market varies, and brands and products with reliable quality and good reputation should be selected. High-quality repair kits are usually made of high-quality materials, with high processing precision, can meet the working requirements of the injector, and have good durability. For example, repair kits from well-known brands such as Bosch and Delphi have good guarantees in terms of quality and performance.
Professional maintenance and installation: The maintenance of the injector requires certain professional knowledge and skills, and it is recommended that professional maintenance personnel perform installation and debugging. Maintenance personnel should be familiar with the structure and working principle of the injector, operate according to the requirements of the maintenance manual, ensure that each component is installed correctly and well sealed, and perform necessary debugging and testing to ensure the normal operation of the injector.
