Types of Injectors Standard injectors can be divided into two categories: needle standard injectors and orifice standard injectors. Among them, standard pivot injectors include S series pivot standard injectors and T series pivot standard injectors. S series pivots are mainly used for debugging small and medium power engine fuel injection pumps, T series pivots are used for debugging high power engine fuel injection pumps (such as marine/locomotive engine oil pumps); German BOSCH company has a variety of standard orifice injectors, which are suitable for debugging different types of fuel injection pumps. At present, my country's orifice standard injectors include low inertia orifice standard injectors and ordinary orifice standard injectors. With the development of fuel injection pumps, low inertia orifice standard fuel injectors are also widely used. T-type fuel injection pumps have become more and more popular in our country. The low inertia orifice standard fuel injector is used to debug this type of fuel injection pump, which can well solve the problems that occurred when debugging this type of fuel injection pump in the past. For example: it is difficult to debug the uniformity of each cylinder, and it is difficult to take into account the uniformity of rated speed, maximum torque speed, idle speed, etc.
