Zusammenfassung:The invention provides an oil-gas separation structure of a camshaft assembly, and belongs to the technical field of engines. The problem that an existing oil-gas separation structure is inconvenientto machine is solved. The oil-gas separation structure of the camshaft assembly comprises an oil-gas channel and a curved joint which penetrate through a camshaft in the axial direction of the camshaft, wherein a separation raised line which is spirally arranged in the axial direction of the camshaft is arranged on the outer side wall of the gas inlet end of the curved joint; the gas inlet end ofthe curved joint is arranged in a gas outlet of the oil-gas channel in a penetrating mode; and a spiral separation oil channel for engine oil to pass through is formed among the inner wall of the oil-gas channel, the outer side wall of the curved joint and the separation raised line. The oil-gas separation structure of the camshaft assembly has the advantage of being convenient to machine. 本发明提供了一种凸轮轴组件的油气分离结构,属于发动机技术领域。它解
