1. Check and clean the fuel injector: Regularly check whether the oil passage of the fuel injector is blocked, whether the valve needle is worn or damaged, and if necessary, clean or replace it.
2. Check and adjust the injection pressure: Ensure that the injection pressure of the fuel injector is within the specified range. If the pressure is abnormal, it needs to be calibrated to the parameter values specified by the manufacturer.
3. Check and replace diesel filters: Regularly check and replace fuel filters to ensure fuel cleanliness and prevent dust and impurities from entering and exacerbating damage to needle valve components.
4. Check and replace seals: Seals are key components to ensure the normal operation of fuel injectors. If they are damaged or aged, they need to be replaced in a timely manner.
5. Check and adjust injection timing: Ensure that fuel is injected into the combustion chamber at the correct timing.
6. Check and replace wiring harness and connectors: Check whether the electronic control wiring harness or mechanical connecting oil pipe of the fuel injector is intact. If there is damage or poor contact, it needs to be replaced or repaired.
7. Regularly inspect the fuel supply time of the oil pump: If the fuel supply time is too early or too late, it will affect the performance of the diesel engine and needs to be inspected and adjusted regularly.
8. Avoid using fuel that does not meet the standards: Fuel that meets the specified standards must be used and must be filtered for at least 48 hours to reduce wear on the needle valve components and prevent nozzle blockage.
9. Clean up carbon deposits: Regularly clean the carbon deposits on the fuel injector to prevent the needle valve from jamming or burning.
10. Check and replace severely worn components: For fuel injector components that are severely worn or cannot be repaired, new components should be replaced in a timely manner.
Through the above maintenance measures, the service life of Weichai diesel generator fuel injectors can be effectively extended, ensuring their normal operation and reducing the possibility of malfunctions.
