Distribution block for high-pressure common rail system and control method thereof

The invention discloses a distribution block for a high-pressure common rail system. The distribution block comprises a distribution block body, a plurality of high-pressure conversion interfaces mounted on the distribution block body and a pressure control assembly, every two high-pressure conversion interfaces are communicated with each other to form a high-pressure oil path network in the distribution block body, one or more of the high-pressure conversion interfaces serve as a high-pressure fuel oil inlet, the other high-pressure conversion interfaces serve as high-pressure fuel oil outlets, and high-pressure fuel oil enters from the high-pressure fuel oil inlet, is distributed in the high-pressure oil way network and then flows out from the high-pressure fuel oil outlets. According tothe distribution block for the high-pressure common rail system, the functions of high-pressure fuel oil distribution, pressure signal collection, system safety protection and the like can be achieved, and the fuel pressure
