#$%^&*AU2014101537A420150212.pdf#####-7Abstract A cylinder head of a high-speed diesel engine is provided. The cylinder head comprises a cylinder head main body, the ratio of which thickness to a cylinder diameter of the diesel engine is 1:1; and a cylinder head reinforcement disposed 5 on the top of the cylinder head main body. The ratio of the thickness of the cylinder head reinforcement to the cylinder diameter of the diesel engine is in the range of 0.45-0.55, and the cylinder head main body and the cylinder head reinforcement are integrated with each other. The ratio of the total thickness of the cylinder head main body plus the cylinder head reinforcement to the cylinder 10 diameter of the diesel engine is in the range of 1.55-1.75. According to the present invention, the cylinder head has sufficient integral strength, more reliable sealing ability and can bear higher explosion pressure within the cylinder.2/2 A-A 2 --- ---------- -- -------FIG.2
