Performance Testing

The performance testing of diesel EUI injector includes electrical characteristics, accuracy, the tolerance of high temperature, low temperature, pressure as well as leakage, durability and others working conditions testing. These conditions of each diesel EUI injector will be tested before our diesel EUI injectors are sent to customers.

Above are the tests needed to be done after the diesel EUI injectors are finished producing. However, regular checking also very important to keep the diesel EUI injector perform well.

In order to make sure the diesel EUI injector works normally, there are some parts of diesel EUI injector needed to be checked regularly and before installing to diesel EUI 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 EUI injector. The tight cap of the diesel EUI injector must be replaced after being disassembled for more than 5 times, as shown in the following.

② Replace the tight cap of the diesel EUI injector and the copper gasket of the diesel EUI injector

③ Check whether the gap between the diesel EUI injector needle and the diesel EUI injector 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 diesel EUI injector tight cap deformation, cracking, thread damage, quenching, leakage, will lead to black smoke vehicle cap, diesel EUI injector damage.

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

These are some precautions you need to know to maintain an diesel EUI injector. If there are more questions about diesel EUI injectors and other problems, you are welcomed to contact us, euiinjector.com will do the best to help you solve your problems.
