TLDR
The high common rail system model of GDI engine is established and the random algorithm is used to obtain the optimal controller parameters, and a basis is provided for optimally designing the parameters of the cylinder diameter and common rail volume.Abstract:
The stable operation of common rail system is significant for GDI engine and the rail pressure fluctuation affects the engine performance directly. The common rail volume and the cylinder diameter are the key structure parameters of common rail system to affect the rail pressure fluctuation. To design the structure parameters of high common rail system for decreasing the rail pressure fluctuation, the high common rail system model of GDI engine is established and the random algorithm is used to obtain the optimal controller parameters. Then, through the simulation experiments, the effects of structure parameters on the stability of common rail pressure are analyzed. Finally a basis is provide for optimally designing the parameters of the cylinder diameter and common rail volume.read more
