How to clean the injector itself?

The cleaning steps of automobile fuel nozzle are as follows:

1. Open the engine hood and remove the fixing screws of the fuel distribution pipe with a Phillips screwdriver.

2. After unscrewing the fuel distribution pipe screw, gently shake the fuel distribution pipe with both hands and remove it. Be careful during disassembly to avoid damaging the fuel nozzle sealing ring.

3. Disconnect the wires connected to the battery, especially the power cord of the negative electrode of the battery, to prevent the fuel pump from working accidentally.

4. Remove the fuel injector from the fuel distribution pipe.

5. Connect the self-made fuel injector plug and wire with the fuel injector.

6. Clean the fuel injector with detergent.

7, in the process of cleaning the nozzle, always keep the wire connected to the battery anode.

8. Connect the negative pole of the wire to make the nozzle simulate the working state of oil injection, so as to achieve the purpose of cleaning.

9. Clean the nozzle head.

10. After cleaning, install the fuel injector in the oil return rail.

Extended data

The problem of cleaning time depends on the condition of the car and the quality of fuel added at ordinary times. Generally speaking. The car is in good condition and the fuel quality can be extended to about 40,000 ~ 60,000 kilometers. When the injector is slightly blocked, it also has a certain impact on the vehicle condition.

Sometimes, there will be such a fault: the car is a little shaky when it starts in first gear, and it disappears when it accelerates in high gear. Assuming that all kinds of sensors on the car are working normally, the throttle is clean and the circuit is normal, it is likely that the fuel injector is slightly blocked.

However, when accelerating in high gear, slight gum may be sprayed away (dissolved) again, and the performance of the car will be restored. This slight blockage of the fuel nozzle can usually be avoided. Because slight gum can be dissolved. Therefore, in daily driving, you should always run at high speed to reduce the possibility of carbon deposition.

If the fuel injector is not cleaned for a long time, the blockage will be more serious when the gasoline quality is poor or the vehicle runs for a long time, resulting in poor fuel injection, poor fuel injection angle and atomization, poor engine performance at idle speed, acceleration or full load, reduced engine power, increased fuel consumption, aggravated emission pollution, and even made the engine unable to work. Therefore, the nozzle should be carefully cleaned and inspected regularly to ensure its good work.
