上が図れる。 By the way, by opening the oval-shaped intake valve port 11 and exhaust valve port 13 in the combustion chamber wall 10 as described above, the opening area of these openings can be reduced from that of the conventional circular intake valve port.
It can be expanded significantly compared to the exhaust valve port, that is, if the distance di between adjacent intake valves 6 and the distance de between adjacent exhaust valves 7 are kept constant as shown in FIG. , the minor diameters Di and De of the oval or elliptical intake and exhaust valve ports 11 and 13 are the same as when the conventional circular intake and exhaust valve ports are opened (as shown by the dashed line in Fig. 3). Since it is equal to the diameter, the intake and exhaust valve ports 11 and 13 of this embodiment are naturally larger than the conventional circular intake and exhaust valve ports, and the total effective opening area of the total intake and exhaust valve ports 11 and 13 is Compared to the case where the conventional circular suction and exhaust valve ports are opened, the valve openings are enlarged as much as possible, and the suction and exhaust efficiency can be improved.

改善し、その出力向上を図ることができる。 As described above, according to the first invention, the intake valve port opened in the combustion chamber wall of the cylinder head, the seat portion of the intake valve that opens and closes the port, and the exhaust valve port and the seat portion of the exhaust valve that opens and closes the port. Since at least one of the valves is formed into an oval shape or an oval shape, the effective opening area of the valve port can be expanded.Moreover, the intake and exhaust valves can be formed simply by making their seat portions oval or oval. Since the weight does not increase to the extent that it interferes with operation, it is possible to improve the intake and exhaust efficiency of the engine and increase its output.

Since it is formed in an oval or oval shape facing in the axial direction, the individual opening area is large and multiple valve ports can be arranged at the required predetermined intervals, making it possible to increase the effectiveness of multiple valve ports. The total area can be significantly expanded, and the weight of each intake valve and/or exhaust valve that opens and closes these valve ports is only made into an oval or oval shape, which increases the weight compared to conventional ones. As a result, the overall output per unit volume of the engine can be significantly improved, and the engine can be made smaller and lighter.
