Performance Test

Our performance testing of the injection valve set encompasses assessments of electrical characteristics, accuracy, tolerance to high and low temperatures, pressure, leakage, durability, and other working conditions. Each injection valve set undergoes rigorous testing to evaluate its performance under these conditions before being dispatched to customers.

Above are the tests needed to be done after the injection valve set are finished producing. However, regular checking also very important to keep the injection valve set perform well.

In order to make sure the injection valve set works normally, there are some parts of injection valve set needed to be checked regularly and before installing to injector.

① Check whether there is deformation, cracking, thread damage, quenching, leakage and rust in the guide sleeve, spring, gasket and tight cap of the injection valve set. The tight cap of the injection valve set must be replaced after being disassembled for more than 5 times, as shown in the following.

② Replace the tight cap of the injection valve set and the copper gasket of the injection valve set

③ Check whether the gap between the injection valve set needle and the injection valve set shell is within the standard range and whether it reaches the standard for use

④All parts should be examined for wear under a microscope at least 20 times larger

⑤ injection valve set tight cap deformation, cracking, thread damage, quenching, leakage, will lead to black smoke vehicle cap, fuel injector damage.

⑥injector opening pressure greater than or less than the specified range may cause injector damage.
⑦ Failure to replace wearing parts in time during maintenance may lead to fuel injector damage.

These are some precautions you need to know to maintain an injection valve set. If there are more questions about injection valve set and other problems, you are welcomed to contact us, injectionvalveset.com will do the best to help you solve your problems.
