6. DLLA155P876 Injection Nozzle’s Quality Control

（1）Injection Nozzle Testing

All parts of the injection nozzle are subjected to precision testing, high temperature testing, low temperature testing, withstand pressure testing, leakage testing, durability testing, and various working conditions testing.

（2）Injection Nozzle Inspection

The factory inspection of the injection nozzle is undergone full inspection, random inspection, and batch inspection three inspections. Different brands of test benches are used to test the same Injection Nozzle for a total of no less than three times for factory inspection, and the fuel injector installation testing environment are progressed in dust-free workshop.

（3）Injection Nozzle Installation

When matching the nozzle needle and nozzle, Shumatt strictly complies with the standard of nozzle needle and nozzle clearance technical indicators to ensure that each injection nozzle meets the factory standards and use standards.

7. DLLA155P876 Injection Nozzle’s Causes of Damage 

（1）Fuel injection nozzle failure caused by impurities (water, lead, aluminum powder, iron powder, sulfide) in fuel exceeding standard requirements.

（2）The nozzle is normally worn due to long time working under high temperature

（3）Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector cannot work properly.

• Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector can’t work properly.
• The wear of the nozzle leads to the increase of fuel quantity, resulting in black smoke of the vehicle, and the fuel injector can’t work properly when it is serious.
• If the nozzle needle can’t move smoothly stuck may cause serious damage to the Injection Nozzle
• The rusting of the nozzle spring leads to spring fracture and black smoke from the vehicle.
• The opening pressure of the nozzle decreases, and the oil quantity of the injector increases, leading to black smoke of the vehicle, and the injector can’t work properly when it is serious.
• Oil-nozzle needle valve lift adjustment gasket wear oil-nozzle needle valve stroke becomes larger, the fuel injector oil quantity becomes larger, resulting in black smoke of vehicles, resulting in the fuel injector can’t work properly when serious.

The cracking of the nozzle cap is caused by high intensity work under high temperature.

8. DLLA155P876 Injection Nozzle’s Installation Precautions

• Clean the injection 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 valve assembly fall off.
• Use compressed air to clean the cleaning fluid attached to the surface of the Injection Nozzleafter cleaning, and clean it up to the standard of use, as below
