The working principle of the gasoline injector !
The fuel injection nozzle is a simple solenoid valve. When the solenoid coil is energized, suction is generated. The needle valve is sucked up and the injection hole is opened. The fuel is ejected at high speed through the annular gap between the needle and the injection hole on the needle valve head. Mist, good for full combustion.

What are symptoms of a problematic injector ?
- Check Engine Light/Misfiring engine caused by a change in the injector's flow
- Noticeable fuel odor caused by leaky injector
- Reduced gas mileage caused by an incorrect injector spray pattern
- Inconsistent engine idling, hesitation or stalling caused by dirty injectors due to low quality fuel
- Check Engine Light (CEL);Starting Issues;Bad fuel economy;Engine RPM/ Performance issues

Should you replace all injectors at once ?
If an injector is faulty on a vehicle with high mileage chances are the remaining injectors are in a similar condition, or will be in the near future. Replacing your injectors as a set ensures each cylinder is receiving the same amount of fuel leading to better performance and improved fuel economy. Since the time required to replace a single injector is about the same as replacing all the injectors it is recommended to replace them as a set.

Installation instructions for fuel injectors
- First disconnect the plug from the injector. Then disconnect the vacuum tube and fuel return tube from the fuel pressure regulator, and then disconnect the fuel hose from the distributor.
- Remove the retaining nuts on the distributor and harness rack.
- Remove the distributor ,then remove the injector from the distributor
- First insert the injector into the distributor. Then attention should be paid to applying a clean oil layer to the new seal ring and then pressing the fuel injectors into the intake manifold .(Pay attention to the damage of the 0-ring,and the injector should be installed on the distributor first, and then on the intake manifold)
- Replace the fuel hose with a new washer and connect it to the distributor. Then connect the plug on the injector and harness, and connect the vacuum hose and return pipe to the fuel pressure regulator. And then install intake manifold and intake manifold cover.




Diagnose Fuel Nozzle Injector Faults and Resolve Faults
Fuel Injection Hole Blockage
- The needle can be used for dredging, and it should be carefully cleaned after dredging.
Poor Sealing of Needle Valve and Needle Valve Body, Resulting in Poor Atomization or Dripping of the Injector
- This kind of failure can be applied to the sealing tape at the end of the needle valve with fine chrome oxide or toothpaste, but never put it on the cylindrical part, then insert the needle valve into the needle valve body and knock it until it closes.
- The chromium oxide or toothpaste must be washed away after grinding.
Air in the Oil Circuit
- Simply remove the air from the oil circuit.
Poor Oil Supply
- Repair the oil pump. If the oil pipe joint leaks, try to connect it so that it does not leak.
Insufficient Spring Force of the Piston Spring or Spring Break
- Replace the spring.
Piston Wear, Affecting Oil Supply
- Replace the piston.
