<p>Disclosed are an air-cooled universal cylinder head for a vertical-shaft gasoline engine and a gasoline engine having same, comprising a cylinder head body (1), an intake passage (12) disposed on said cylinder head body (1), and an exhaust passage (11) disposed on said cylinder head body (1). The outside surface of the cylinder head body (1) is provided with cooling fins, and the inside of said cylinder head body (1) forms a combustion chamber surface. An intake valve (5) corresponding to the intake passage (12) is provided on the cylinder head body (1). An exhaust valve (9) corresponding to the exhaust passage (11) is provided on the cylinder head body (1). On the combustion chamber surface, a bridge region (14) is formed between the intake valve (5) and the exhaust valve (9), and an air-cooling passage (10) is provided outside of said bridge region (14). The bridge region, the intake valve, and the exhaust valve have a good cooling effect, ensuring that the area near the intake valve, the exhaust valve, and the bridge region is not physically deformed, thereby ensuring that the intake and exhaust valves are well sealed.</p> |
