High-pressure oil pump seat mounting structure

A high-pressure oil pump seat mounting structure belongs to the technical field of engines. The high-pressure oil pump seat body is integrally installed on the cylinder cover through the camshaft bearing cover, the included angle between the installation axis of the high-pressure oil pump seat body and the vertical tangent plane of the bottom face of the cylinder cover is alpha, alpha ranges from 50 degrees to 60 degrees, and the overall height of an engine can be reduced. A first support mounting point is arranged on a high-pressure oil pump seat body, a second support mounting point is arranged on a cylinder cover, and the first support mounting point and the second support mounting point are connected through a support and used for solving the resonance problem of the high-pressure oil pump seat body and a high-pressure oil pump. The large-dip-angle high-pressure oil pump seat with the support is integrated with part of the camshaft bearing cap, the compact arrangement structure is achieved, the overall he
