Diesel Injector Nozzle Dlla162p2160 0433172061 for Fuel Injector 0445110369 for Fuel Parts

In order to overcome the shortcomings of the above-mentioned metal inclusion detection method, metallographic samples can be made by collecting the metal impurities inside the injector nozzle, and the metallographic samples of metal inclusions can be combined with the filtered fuel oil. The gas sent by the filter to the injector passes through the metallographic samples of the metal parts that have been in contact, and the metallographic structure is compared and analyzed to determine the source of the blockage. The method is simple, fast and easy to operate, can be detected and judged by conventional instruments, and has practical value for popularization.
4 Implementation Cases
A certain company produced a batch of fuel injectors of a certain type for export. Bulk clogging occurs due to metallic impurities clogging the fuel. After on-site inspection, no diesel fuel was found in the fuel supply system of the diesel engine. The filter is damaged, that is, the diesel filter is clean and functional, and it is difficult to find out the cause.
Analyze according to the above technical scheme:
1) Collect the metal impurity blockage in the fuel injector to make a metallographic sample.
2)
3) Collect the metal parts that the fuel oil filtered by the diesel filter 3 in the fuel injector passes through and contacts, and make metallographic samples.
3) Compare and judge to determine the cause of the blockage of metal impurities in the injector.
