AB - The entry and ejection of fuel into and out of high-pressure oil tube are the basis of many fuel engines. However, the intermittent working process of fuel entering and exiting will be leading to pressure changes in high-pressure oil tube. Furthermore, it will affect the efficiency of an engine. Therefore, it can be seen important to control high-pressure oil tube effectively. Also, it will be increasing the efficiency of an engine, while having a greatly impact on the development of engine manufacturing and energy industry. This paper is to focus on solving pressure control under high-pressure oil tube. The problems are stable pressure at the inlet of the high-pressure tubing and high-pressure oil tube with no pressure reducing valve and only one nozzle. Regarding the first one, we used the least square method to fit an elastic modulus and pressure data. Then, a differential equation model of pressure and time were set inside high-pressure oil tube. Meanwhile, we also worked on a delayed injection strategy and traversal search algorithm to have results. So, the optimal delayed injection time is 0.23 ms while the one-way valve opening time is 3.06 ms . The maximum offset pressure is about0.3 MPa. The second case which is based on the first case. In order to achieve pressure control, linking the pressure at the inlet of high-pressure oil tube to a cam and using the principle of mass conservation. So, it is stated that the pressure can be stabilized as much as possible when the angular velocity is 0.0275 rad/ms. Finally, we verified the feasibility of the model through simulation analysis.
