Performance Testing

The performance testing of diesel injections 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 injections will be tested before our diesel injections are sent to customers.

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

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

② Replace the tight cap of the diesel injections and the copper gasket of the diesel injections

③ Check whether the gap between the diesel injections needle and the diesel injections 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 injections 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 diesel injections. If there are more questions about diesel injections and other problems, you are welcomed to contact us, dieselinjections.com will do the best to help you solve your problems.
