The cylinder cover comprises a cylinder cover air inlet, an air inlet channel, an air inlet throat, an air outlet throat and an air inlet valve seat ring, the edge of the side, away from the air outlet throat, of the air inlet throat is a first edge, and the edge of the side, close to the air outlet throat, of the air inlet throat is a second edge. The air inlet channel comprises a first wall face connected to the first edge and a second wall face connected to the second edge, the first wall face is provided with a tumble sharp corner located above the air inlet valve seat ring, and the first wall face and/or the second wall face are/is further provided with a pre-casting flow guide part used for guiding inlet air flow to the second wall face at the upstream position of the tumble sharp corner. By arranging the pre-casting flow guide part and the tumble sharp corner in the air inlet channel, distribution of inlet air flow in the air inlet channel can be achieved, effective flow guide of the inlet air flow is
