The invention belongs to the technical field of engines, and particularly relates to a cylinder head cover and an engine with same. The cylinder head cover comprises a cylinder head cover body, wherein a camshaft bearing seat and an air inlet rocker shaft bearing seat are arranged on the cylinder head cover body; and the camshaft bearing seat, the air inlet rocker shaft bearing seat and the cylinder head cover body are integrally cast and formed. According to the cylinder head cover, the camshaft bearing seat and the air inlet rocker shaft bearing seat are arranged on the cylinder head cover body, so that the camshaft bearing seat and the air inlet rocker shaft bearing seat can be integrated on the cylinder head cover, and the casting difficulty of a cylinder head is reduced; and in addition, the camshaft bearing seat, the air inlet rocker shaft bearing seat and the cylinder head cover body are integrally cast and formed, so that the number of parts of the engine is reduced, the structure of the engine is simplified, and the production cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a cylinder head cover and an engine with the same. Background technique [0002] Camshafts and rocker shafts are mainly used to open and close the valves. Some camshafts and rocker shafts are installed on the camshaft bearing seat and rocker shaft bearing seat integrated on the cylinder head. The camshaft bearing seat and rocker shaft The integration of the arm bearing housing on the cylinder head increases the casting difficulty of the cylinder head, and some camshafts and rocker shafts are supported on the cylinder head through independent camshaft bearing housings and rocker shaft bearing housings, which increases the number of engine parts , increased production costs. Contents of the invention [0003] The purpose of the present invention is to at least solve the problem that the existing camshaft bearing housing and rocker shaft bearing housing increase the c...
