Performance Test

Before dispatching our CR, E1, and Smart common rail injector nozzles, each unit undergoes a thorough performance test. This testing evaluates various factors such as electrical characteristics, accuracy, temperature tolerance, pressure resistance, leakage, and overall durability. By subjecting our nozzles to these rigorous tests, we ensure that each one meets the highest standards of quality and performance. This meticulous process guarantees that our customers receive reliable and high-performing common rail injector nozzles.

Above are the tests needed to be done after the Common Rail Injector Nozzle are finished producing. However, regular checking also very important to keep the diesel injector nozzle perform well.

In order to make sure the common rail injector nozzle works normally, there are some parts of common rail injector nozzle 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 diesel injector nozzle. The tight cap of the common rail injector nozzle must be replaced after being disassembled for more than 5 times, as shown in the following.

② Replace the tight cap of the diesel injector nozzle and the copper gasket of the common rail injector nozzle

③ Check whether the gap between thecommon rail injector nozzle needle and the common rail injector nozzle 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 common rail injector nozzle 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 common rail injector nozzle. If there are more questions about common rail injector nozzle and other problems, you are welcomed to contact us, www.crdiinjectornozzle.com will do the best to help you solve your problems.
