Engine oil rail assembly and automobile

The utility model is suitable for the technical field of vehicles, and provides an engine oil rail assembly and an automobile. The engine oil rail assembly comprises a fuel oil guide rail and a pre-combustion oil injector. According to the engine oil rail assembly, the pre-combustion oil injector is installed on the fuel oil guide rail, the fuel oil guide rail is directly connected with the pre-combustion chamber, the dimension chain from the tip end of the pre-combustion oil injector to the inner wall of the inner cavity of the pre-combustion chamber is shortened, and the dimension accumulated tolerance is reduced; the statistical tolerance range of the distance from the tip end of the pre-combustion oil injector to the inner wall of the inner cavity of the pre-combustion chamber is-1.0 mm to + 1.0 mm, and the situation that the tip end of the pre-combustion oil injector collides with the inner wall of the pre-combustion chamber is effectively avoided. 本实用新型适用于车辆技术领域，提供了一种发动机油轨总成及汽车。发动机油轨总成包括燃油导轨和预燃烧喷油器。本实用新
