高压油管的压力控制问题研究

On the Problem of Pressure Control of High-pressure Oil Tube

摘要: 供油系统对其柴油机的性能具有重要的影响。根据高压油管的相关工作原理，本文给出了针对燃油进入和喷出过程对应的动力系统数学模型，并利用MATLAB对高压油管的运作过程进行了数值模拟。相比现存的模型，本文的模型具有更好的可操作性和有效性。

Abstract: The fuel supply system plays an extremely important part in the performance of diesel engine. One mathematical model of dynamical system for the process of fuel entering and ejecting is given in this paper based on the operating principle of high-pressure tubing. Simulation of the operation process of high-pressure oil tube is added to illustrate our results. Compared with the models in the literature, ours is more feasible and useful.
