High Quality Common Rail Control Valve Set Assembly F00RJ02410 for Diesel Injector

Preventive Measures for Early Wear of Needle Valve Couplings
(1) Prevent the intrusion of impurities. The matching accuracy of the injector needle valve couple is extremely high, and the nozzle hole diameter is very small, so the clean diesel oil of the specified brand must be selected strictly according to the seasonal changes. Pay attention to cleanliness during storage and filling, and do not mix impurities in diesel oil. Before use, it must be precipitated and filtered before being added to the fuel tank. Maintain the diesel filter on time, and drain the precipitated oil in the filter and fuel tank frequently to prevent the intrusion of dust and sand impurities and aggravate the wear of the needle valve assembly. When replacing or disassembling parts such as high-pressure oil pipes, diesel filter elements, plunger pairs, and oil outlet valves, they should be cleaned first before installation, and before the high-pressure oil pipes are connected to the fuel injectors, the accelerator should be opened to drive the engine to idle for several times. circle to clean the channel of the high-pressure oil pipe.
(2) The anti-rust oil should be removed from the newly replaced needle valve assembly to prevent the needle valve from sticking due to the melting of the anti-rust oil when the injector is working. Boil the new fuel injector assembly in 70~80C diesel oil for 10 minutes, and then move the needle valve back and forth in the valve body in clean diesel oil to clean the anti-rust oil thoroughly. When cleaning the injector needle valve assembly, do not collide with other hard objects to avoid scratches. For multi-cylinder diesel engines, it should be noted that the needle valve assembly is a matched precision part, and they are not interchangeable.
