The invention provides an engine cylinder head. The engine cylinder head comprises a water inlet, a water outlet, an exhaust port and a plurality of exhaust passages which are arranged corresponding to the plurality of combustion chambers and converged to the exhaust port, an exhaust valve is arranged in the exhaust passages, a cooling water jacket is formed between the water inlet and the water outlet, the cooling water jacket comprises a water jacket main body, a lower water jacket which is extracted from the side of each combustion chamber of the water jacket main body and an upper water jacket which passes through the exhaust valves of each combustion chambers and is connected with the water jacket main body, the lower water jacket and the upper water jacket are respectively covered onthe lower part and the upper part of each exhaust passage, wherein the lower water jacket and the upper water jacket are respectively provided with a hollow area on the positions of the correspondingexhaust passages. The engine cylinder head can not only utilize the heat in the exhaust gas to heat the cooling liquid so as to realize rapid warm-up, but also can avoid influence of the cooling water jacket on the heat dissipation of a radiator.
