“…Therefore, a diesel engine that is equipped with a highpressure common rail system has the potential to achieve the optimized design goals of high-efficiency combustion and ultralow emission [1][2][3][4][5]. The common rail injector is one of the high-pressure common rail system's critical components, with a direct influence on the cycle fuel injection quantity fluctuation, gas-liquid two-phase flow characteristics of highpressure fuel in the nozzle, fuel atomization characteristics in the cylinder, and air-fuel mixture quality [6][7][8][9]. The common rail injector is a complex, nonlinear, and multidimensional system that couples electromagnetic, mechanical, and hydraulic phenomena.…”

A novel formula easily applied with high precision is proposed in this paper to fit the -curve of soft magnetic materials, and it is validated by comparison with predicted and experimental results. It can accurately describe the nonlinear magnetization process and magnetic saturation characteristics of soft magnetic materials. Based on the electromagnetic transient coupling principle, an electromagnetic mathematical model of a high-speed solenoid valve (HSV) is developed in Fortran language that takes the saturation phenomena of the electromagnetic force into consideration. The accuracy of the model is validated by the comparison of the simulated and experimental static electromagnetic forces. Through experiment, it is concluded that the increase of the drive current is conducive to improving the electromagnetic energy conversion efficiency of the HSV at a low drive current, but it has little effect at a high drive current. Through simulation, it is discovered that the electromagnetic energy conversion characteristics of the HSV are affected by the drive current and the total reluctance, consisting of the gap reluctance and the reluctance of the iron core and armature soft magnetic materials. These two influence factors, within the scope of the different drive currents, have different contribution rates to the electromagnetic energy conversion efficiency.

“…Given the trends in the automotive industry, today it is necessary to have a resource of about 500 thousand km. It gives to designer the task of increasing the reliability of the most vulnerable elements of the diesel injectors: friction pairs, injector cone seat, nozzle holes and injector nozzle tip [1][2][3][4][5].…”

The application of abrasive suspension flow machining (ASFM) to grind a diesel engine injector nozzle is discussed in this paper. The purpose is to remove the sharp corners of the spray holes and improve the fuel flow through the injector nozzle. The proposed method adopts one-way flow to grind the spray holes for high-efficiency production. Compared with traditional reciprocating flow grinding methods using abrasive pastes, the viscosity of slurry and abrasive concentration of ASFM are lower, better for more smooth flow. To achieve a good grinding performance, it is important to determine proper viscosity and concentration. For this purpose, a design of experiments (DoE) method is adopted. In this paper, an orthogonal test method is combined with a nonlinear regression method to optimize the process parameters. Through a range analysis on experiment results, the optimal process conditions in terms of the grinding efficiency and the grinding quality are determined. Experiment verifications show that the optimized process parameters can significantly improve the ASFM grinding efficiency and grinding quality.
