(8)  G3S40 Liwei Injector Nozzles Installation Precautions

  • Clean the injector nozzlein an ultrasonic cleaner for 3-5 minutes before installation, so as to make the stains, dust, rust-proof oil oxides, paraffin base, naphthenic base,  intermediate base, salt, lead naphthenate, zinc naphthenate,  sodium petroleum sulfonate, barium petroleum sulfonate, calcium petroleum sulfonate, tallow diamine trioleate, rosinamine on the surface of the nozzle fall off.
  • Use compressed air to clean the cleaning fluid attached to the surface of the nozzleafter cleaning, and clean it up to the standard of use,  as below.

(9) G3S40 Liwei Injector Nozzle Inspection.

  • Check whether there is deformation, cracking, thread damage, quenching, leakage and rust in the guide sleeve, spring, gasket and tight cap of the nozzle. The tight cap of the nozzle must be replaced after being disassembled for more than 5 times, as shown in the following.
  • Replace the tight cap of the  nozzle and the copper gasket of theLiwei injector nozzle
  • Check whether the gap between the nozzle needle and the nozzle shell is within the standard range and whether it reaches the standard for use
  • All parts should be examined for wear under a microscope at least 20 times larger
  • Nozzle tight cap deformation, cracking, thread damage, quenching, leakage, will lead to black smoke vehicle cap, fuel injector damage.
  • Injector opening pressure greater than or less than the specified range may cause injector damage.
  • Failure to replace wearing parts in time during maintenance may lead to fuel injector damage.

(12) G3S40 Liwei Injector Nozzle’s Storage Standard

  • Choose a suitable storage place

The warehouse and cargo yard where the fuel injector is stored should be kept clean and dry, and away from the factory buildings that generate harmful gases and dust; do not mix with acid, alkali, salt and other substances; the storage place should have a good drainage system; the cargo yard should be flattened with gravel or furnace ash etc. to enhance the water permeability of the surface layer to keep the reservoir area dry.

  • Strict requirementsof warehousing

Strict inspections should be carried out when the fuel injectors are put into storage,   the surface cleaning work should be done well to remove water traces, oil stains, ash and other dirt, remove the rust and do anti-rust treatment in time. Packaged injectors must be protected from damage.

  • Keep the warehouse dry and preventing moisture

The relative humidity is usually below 70% for the fuel injectors placed in the room, and the corrosion of the fuel injectors is significantly reduced.


Injectors must be stored in the warehouse, and they are forbidden to store in the same warehouse with commodities with high water content.

  • StackProperly

After the injector is exposed to rain, the corrosion rate will increase significantly. The purpose of sealing is to isolate the injector from rainwater and humid air,   so the warehouse window should be checked in time to avoid rainwater entering the warehouse

If the fuel injector package is damaged, it should be repaired or replaced; when the package is damp, the packaging material should be dried; if the original anti-corrosion and oil applied at the factory is found to be damaged or dried up, it should be cleaned and re-applied oil in time.

It is forbidden to leave the injector exposed in the air for a long time.

It is forbidden to store acid, alkali, salt and other substances together with the injector.

The unpacked fuel injector must be rust-proof during secondary storage.
