The intermittent working process of fuel entry and injection will cause the pressure in the high-pressure fuel pipe to change, causing deviations in the amount of injected fuel, which will affect the engine’s operating efficiency. Taking a high pressure oil pump system as an example, the feasibility of using constant pressure to improve the working efficiency of the high pressure fuel system is studied. First, a series of simplified assumptions are made for the model. Secondly, use MATLAB software to make cam mechanism diagram. A cam angular velocity model based on pressure stability was established using the fuel quality of one injection of the injector and the fuel quality of one cam rotation. Calculate the number of times the cam needs to rotate to get the time that the cam needs to rotate once, so as to determine the high stability of the cam. The angular velocity required for tubing pressure was obtained.
