Hot Sale Fuel Injection Fixed Block for C7 C9 Common Rail Injectors C7 / C9 Spacer Valve Auto Engine Parts

Function
Positioning: Ensure that the fuel injector is installed accurately on the engine, so that the fuel injector can accurately inject fuel to a specific part of the engine, and ensure the accuracy and consistency of fuel injection.
Fix: Fix the fuel injector firmly on the engine block or cylinder head to prevent the fuel injector from being displaced or loosened due to vibration during engine operation, affecting the fuel injection effect.
Sealing: Usually used in conjunction with seals to prevent fuel leakage, ensure the sealing of the fuel system, and improve the efficiency and reliability of fuel injection.
Type
Plate type fixing block: The fuel injector is pressed on the engine by a pressure plate and bolts. It has a simple structure and is easy to install. It is often used in some small and medium-sized engines.

Screw sleeve fixing block: The fuel injector is screwed into the engine block or cylinder head using a hollow screw sleeve. It has a good fixing effect and sealing performance. It is generally used in engines with high requirements for injector fixing.
Flange type fixing block: The injector itself has a flange, which is fixed to the engine by bolts. This fixing method can make the installation of the injector more stable and is often used in some large engines.

Material
Metal material: such as steel, aluminum alloy, etc., has high strength and hardness, can withstand the vibration and impact during the operation of the engine, ensure the fixing effect of the injector, and have good thermal conductivity, which helps to dissipate heat.
Engineering plastic material: It has the advantages of light weight, low cost, and good insulation performance. Some small engines or vehicles with weight requirements may use fixing blocks made of engineering plastics.

Maintenance and care
Regular inspection: When maintaining the engine, check whether the fixing block is loose, deformed or damaged. If there is any problem, replace or repair it in time.
Cleaning treatment: Keep the fixing block and the installation part of the injector clean to prevent oil stains, impurities, etc. from affecting the fixing effect and sealing performance.
Correct installation: When installing the injector fixing block, tighten the bolts according to the specified torque to avoid over-tightening or over-loosening to ensure the normal operation of the fixing block and the injector.
