In-line In-Line Pump-Pipe-Valve-Mouth (PPVI) Diesel injection system is a new type of system for electronic control of mechanical in-line pump-pipe-nozzle system based on the characteristics of various electronic diesel injection systems. The structure and working principle of the electronically controlled in-line pump-pipe-valve-nozzle diesel injection system are analyzed. The control device which meets the working requirements of the system is designed and developed. The feasibility of the operation of the electronically controlled injection system is verified through experiments. The influence of some structure and adjustment parameters on the system performance was studied. The experimental results show that the new type of electronic control injection system has good comprehensive control performance.
