Embodiment Construction
[0012] The present invention will be further described below in conjunction with drawings and embodiments.
[0013] Such as figure 1 , figure 2 , image 3 As shown, the cylinder head of the three-valve engine is provided with a first intake port 1, a second intake port 2, an exhaust port 3 and a combustion chamber 4. Wherein, the lower end of the combustion chamber 4 is open, and the outline of the lower port of the combustion chamber 4 is approximately circular. The inner top wall of the combustion chamber 4 is a double-slope structure, such as figure 1 The one shown on the left is the first slope 4a, the one on the right is the second slope 4b, and the deepest depth of the combustion chamber 4 is 9-13mm. The first slope 4a and the second slope 4b have a smooth transition through a curved surface, and there is an included angle of 120-128° between the first slope 4a and the second slope 4b. In this embodiment, the first slope 4a and the second slope The angle between th...
