摘要： The invention discloses a cylinder head of a small-sized general-purpose gasoline engine and a gasoline engine having the same. The cylinder head of the small-sized general-purpose gasoline engine comprises a cylinder head body (1), and an intake passage (9), an exhaust passage (5) and a sparking plug mounting hole (8) arranged on the cylinder head body (1); a combustion chamber surface (7), being a arched smooth curve, is formed at the inner side of the cylinder head body (1); the cylinder head body (1) is provided with an intake valve (11) corresponding to the intake passage (9) and an exhaust valve (4) corresponding to the exhaust passage (5); the intake valve (11) is inclined towards the intake passage (9) from the bottom part to the top part; the exhaust valve (4) is inclined towards the exhaust passage (5) from the bottom part to the top part; and the included angle between the axis of the intake valve (11) and the axis of the exhaust valve (4) is 24±5 degrees. In the invention, the parameters between the combustion chamber and the intake valve as well as the exhaust valve are inter-coordinated and matched, the operation efficiency of the gasoline engine is improved, the fuel is saved, and the discharge is reduced.
