DLLA155P179 New 100% Tested Common Rail Diesel /Fuel Injector Nozzle

Grinding of fuel injection nozzle needle method. After the generator set injector is disassembled and inspected, if it is found that the cylinder surface of the needle valve is excessively worn, it needs to be replaced with a new product, once it is found that the cone of the needle valve is worn and closed tightly, the needle valve can be repaired by grinding. In the grinding process, pay attention to the correct use of the grinding paste and the grinding method to prevent "more research and more dense".

Pay attention to fuel quality. An important factor affecting the service life and stability of the fuel injector is the quality of the fuel used, in the process of fuel injection nozzle work, the engineer or on-duty engineer of the main equipment must pay attention to the factors that affect the quality of the fuel inlet, such as the filtration of fuel (including gravity precipitation and centrifugal separation), the graded heating of the fuel, the temperature of the fuel feed and the operation of the automation equipment (such as the fuel viscosity control unit) that controls the viscosity of the fuel inlet.

Strengthen the monitoring of the parameters of each cylinder. The parameters of each cylinder related to combustion explain the working situation of the corresponding cylinder, if the working condition of a cylinder is not good, it is usually related to fuel equipment, and the possibility of fuel injection nozzle problems in fuel equipment is very large, and when sailing on duty, pay more attention to observation.
