[0045] In some embodiments, the cylinder head 40 is provided with reinforcing ribs 42, which can not only increase the structural strength and rigidity of the cylinder head, but also increase the natural convection heat dissipation area between the cylinder head and the air, thereby improving the heat dissipation capacity of the cylinder.
