| Abstract: | By analyzing the sealing and lubrication of the plunger matching parts of the fuel injection pump with the oil film theory and gap liquid flow theory, a basic theory and the analytic method are proposed to set the smallest gap between the plunger matching parts. Then aiming at the current typical in-line fuel injection system, a series of analogue computation are made to analyze the fuel leak of the plunger matching parts, the gap pressure, the pressure inside the chamber of the plunger, the fit clearance of the plunger matching parts, and their variations during the operational process. Thus a base is provided for the theory on the design and process improvement of the plunger matching parts |
