“…As one of the key components of the marine diesel engine injection and combustion system, the injector ejects the diesel to the cylinder in the highly atomized state by using the high-pressure oil pump to achieve good cooperation with the compressed air and the combustion chamber [1]. The core power component of the injector is the needle valve assembly which includes needle valve and needle body.…”

Use dynamics theory to establish finite element model of the needle valve assembly of marine diesel engine in the LS-DYNA and transient analysis calculation by explicit solving method. Analyze the time series diagram of equivalent stress of the impact surface and classify the impact phase according to the kinetic theory. Finally, the strength check is performed in the phase where the influence of the impact is most affected by analyzing the calculated equivalent stress results.

To improve the accuracy of fuel injection in high-pressure common rail systems of diesel engine, a mathematical model based on differential equations was established in view of the process of fuel entering and ejecting the common rail pipe, and the pressure variation law under working condition in the common rail tube was simulated in this study. Aiming at reducing the fuel pressure fluctuations in the system, the optimal angular velocity of the cam in high-pressure pump is solved by binary search algorithm, and the optimal control strategies for maintaining the dynamic and stability of pressure are given as well. Numerical simulation results show that with the presented strategies precise control of the pressure can be achieved in the common rail system, helping to improve the efficiency of the diesel engines.
