New Diesel Injector Nozzle Dlla150p1512 0433171933 for Fuel Injector 0445110153 0445110254 0445110726 for Fuel Parts

The metal parts of the fuel contact include the following parts:
A. The 4 parts of the high -pressure pump, namely the main body of the high -pressure pump, the material is ZL111; the plunger, the material is GCR15; the plunger sleeve, the material is 20CRMNTI.
B. Through the 5 parts of the contact fuel injection, the injector shell is made of 45 # steel; the material of the needle valve is W6MO5CR4V2; the material of the needle valve body is 18CR2NI8.
C. The parts passing through the oil pipe, that is, high pressure oil pipe 8, is made of 20 # steel.
Note: The low -pressure oil pipe 7 is made of polychloride chloride. This is not a metal part, so it is not included in the disassembly range.
Collect the fuel filter to make gold -like samples in the fuel injector
① Sample. The main body of the cutting high -pressure pump, nozzle nozzle, plunger, plunger sleeve, injector shell, needle valve, needle valve main body and high -pressure oil pipe, use a wire cutter to remove the upper upper into the sample block.
② Corrosion. Select the "alcohol nitric acid" solution as the polished surface of the corrosive metal impurities. By mixing 4 analysis of pure "nitrate solutions" and 96 analysis of pure "ethanol solutions" to prepare "nitrogen".
③ blow dry. Wash the surface of the nozzle of the injector of the metal impurities with clean water, and then dry it with a "hair dryer". At this point, this indicates that the sample samples of the golden rations have been completed.
