This article continues to introduce the working principle and structure of the hole type fuel injector for diesel generator users. High pressure fuel enters the annular groove at the upper end of the needle valve body through the oil passage in the filter element and injector body from the inlet pipe joint. This groove is connected to the annular space at the lower part of the needle valve body through two inclined holes. The high-pressure diesel flowing through the lower cavity exerts an upward axial thrust on the conical surface of the needle valve. When this force overcomes the frictional force between the pressure regulating spring and the needle valve body (which is very small), the needle valve moves upward and opens the injection hole [as shown in Figure 5-2 (b)]. Therefore, high-pressure fuel is sprayed into the combustion chamber from the injection hole at the lower end of the needle valve body. The lift of the needle valve is limited by the lower end face of the injector bod...
