Providing high‐pressure fuel to the system, the high‐pressure fuel pump is the key component to guarantee the high‐pressure fuel. The working pressure of the high‐pressure fuel pump of the common rail system is very high. This chapter proposes a bottom‐up and solid modeling method. The main reason for the plunger and barrel assembly high‐pressure leakage is the deformation of the sealing clearance. In addition to the general structural stress analysis and dynamic system simulation, the ANSYS finite element analysis software can also be used for an optimization design. Static pressure leakage can only be used as a relative reference to evaluate the effect of structural optimization. The mechanical load on the high‐pressure pump cam‐roller mechanism is mainly the pressure of the upper plunger cavity. The flow control device of common rail pressure regulation mainly controls the common rail pressure changes and fluctuations in the common rail pressure.
