1. 3200690 Injector’s Introduction

Diesel injector is the most critical and complex part in common rail system, and it is also the most difficult part in design and process. By controlling the opening and closing of the solenoid valve, the ECU injects the diesel in the high-pressure diesel rail into the combustion chamber with the best diesel injection timing, diesel injection quantity and diesel injection rate.

5. 3200690 Injector Quality Control

• Injector Testing

All injector spare parts are tested for electrical characteristics, accuracy, high temperature, low temperature, withstand voltage, leakage, durability, and various working conditions.

• Injector Assembling

And the quality control of the injector production and installation process, our company strictly follows the standard product installation data and product installation steps to install, such as injector stroke test, injector solenoid valve tightening torque, injector nozzle tightening torque.

• Injector Inspection

The factory inspection of the injector is undergone full inspection, random inspection, and batch inspection three inspections. Different brands of test benches are used to test the same fuel injector 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.

6. 320-0690 Injector Warranty Instructions

• Product Warranty Conditions and Instructions

It is necessary to provide pictures, videos, or test reports detected by the injector inspection equipment when the injector is abnormal during use as evidence to feed back to the salesman.

Abnormal conditions are properly explained such as：1.Smoke, 2. Engine shake, 3. Difficulty starting the engine, 4. Engine noise, 5. oil leakage etc.

• Injector Warranty Coverage

Within 15 days after customer receives the 320-0690 injector, if there is a performance failure and the product has no appearance damage, customer can choose to replace it or repair it;

If the 320-0690 injector has performance problems during the warranty period (6-12 months), and it is confirmed that it is product’s problems after testing, you can contact our salesmen to replace the same model or a reworked product with the same performance for free;

If the injector house has obvious scratches, it can only be repaired and it will be returned as it is if the product is confirmed to be fault-free.

• Tips：For products not covered by warranty, our company can provide paid maintenance services. For products after paid repaired, the same performance problem will havea free warranty period within 3 months from the date of repair
• Injector Out of WarrantyCoverage

The warranty period has expired.

Injector failure caused by high temperature, high pressure, humidity, rain and snow, saline-alkali land, earthquake, and used in abnormal environment.

Customer disassembles or repairs the injector personally resulting in damage to the injector.

Injector damage caused by man-made reasons (throwing, strong magnetic field magnetization, set fire).

Injector failure or injector damage caused by non-injector design, technology, manufacturing, quality and other issues.

Injector failure due to system pressure exceeding system approved pressure.

Injector failure caused by system voltage exceeding approved voltage.

Injector failure caused by impurities (water, lead, aluminum powder, iron powder, sulfide) in the system fuel exceeding the standard requirements.
