Embodiment Construction
[0019] The present invention will be described below by taking two valves per cylinder as an example.
[0020] As shown in Figure 1 (the cylinder head is in the state of intake air), the valve spring seat (2) is integrated, the distribution valve (4) is installed on the intake port (8), and its intake and exhaust pipes (7) are connected to the intake port (8) communicate; distribution valve (12) device is on the exhaust passage (16), and its intake and exhaust pipe (15) communicates with exhaust passage (16).
[0021] When exhausting, the exhaust cam (10) opens the exhaust valve (11), and under the action of the integrated valve spring seat (2), the intake valve (3) also opens. The valve plate (6) and the valve plate (14) (respectively under the action of the following actuators, the same below) respectively close the intake manifold (9) and the intake manifold (17), and the exhaust manifold (5) and exhaust manifold (13) open. The exhaust gas is discharged through the intake...
