Abstract

The high-pressure fuel system is an important part of the transmitter. In its working process, the oil enters or sprays out, which will cause pressure changes. The pressure in the high-pressure oil pipe is basically stable at about 100MPa, and the density pressure formula is specially corrected. The correction value is +0.018 through the weighted average. The classic PID control algorithm is used to easily realize the control process of voltage stabilization from 100MPa to 150MPa.This paper establishes three models, namely, the high-pressure oil pump model, the fuel injector model and the decompression model. The MATLAB simulation software is used to display the results, and the fuel pressure and quality in the high-pressure oil pipe are used to connect the three models. The parallel operation method reduces the overall operation workload of the system, with good robustness and good scalability.
