The advantages and disadvantages of these solutions are described. These solutions are the criterial prerequisites for the creation of new design injectors and fuel systems. In accordance with the fuel system requirements, these solutions will improve the ICE characteristics at various speeds and conditions. Besides the main schematic offers the ways for further development for the improvement of fuel injection systems are specified. These studies were conducted on the equipment of CAM technology common use center. Keywords: locking element;needle;spring;nozzle;Fuel systems;injection
