The utility model belongs to the technical field of engines, and particularly relates to a cylinder cover and an engine with the same. The cylinder cover comprises a cylinder cover body, an air inletseat ring bottom hole is formed in the cylinder cover body, an eccentric chamfer is arranged on the edge of the air inlet seat ring bottom hole, and the radius of the eccentric chamfer is smaller thanthat of the air inlet seat ring bottom hole. The embodiment of the utility model discloses a cylinder cover. An eccentric chamfer of which the radius is smaller than that of an air inlet seat ring bottom hole is arranged on the edge of the air inlet seat ring bottom hole; a large wall collision angle is formed between the position where the eccentric chamfer intersects with the bottom hole of theair inlet race and the center of the bottom hole of the air inlet race, so that air inlet flow enters the air cylinder in a fixed direction, the flow guide effect of the eccentric chamfer is enhanced, and a large vortex ratio
