Made in China Common Rail Injector Fuel Injector 0445120290 0 445 120 290 for BOSCH Engine Parts

1.Blockage

Problem: The inside of the injector or the nozzle hole may be blocked by deposits, carbon deposits or impurities, causing uneven fuel injection or stopping the fuel injection completely.
Solution: Use a professional injector cleaner for regular cleaning. Sometimes it may be necessary to remove the injector for a more thorough cleaning or replace the blocked parts.
2.Fuel Leakage:

Problem: There may be leaks at the injector seals or connections, causing the fuel to not be injected into the cylinder or causing fuel evaporation.
Solution: Check and replace damaged seals or O-rings. Make sure the injector is installed correctly and tightened.
3.Fuel Injector Solenoid Problem:

Problem: The injector solenoid valve may fail due to electrical problems or damage to the magnetic components, resulting in abnormal fuel injection.
Solution: Check the circuit connections and the working condition of the solenoid valve itself. Replace the solenoid valve or repair it if necessary.
4.Injector Incorrect Spray Angle:

Problem: The spray angle of the injector may be affected by damage or improper adjustment, resulting in ineffective fuel injection into the cylinder.
Solution: Adjust the spray angle of the injector or replace the damaged parts. Make sure the position and angle of the injectors meet the manufacturer's specifications.
5.EFI system pressure problems:

Problem: The fuel pressure of the EFI system is unstable or too high/too low, affecting the normal operation of the injectors.
Solution: Check the fuel pump and pressure regulator to ensure that the fuel supply pressure is stable and within the manufacturer's specified range.
6.Electrical problems:

Problem: Injector electrical connection problems, such as power or ground faults, may prevent the injectors from operating properly.
Solution: Check the circuit to ensure that the injectors are receiving the correct power and ground. Repair or replace damaged electrical components.
