の動弁系構造。 It has valve operating mechanisms A and B that open and close the valves by directly transmitting the force of the cams 8 and 18 to the valve lifters 7 and 17 without changing the direction of force transmission, and also has a valve operating mechanism for a part of the cylinder or valve. A
In the valve train structure of a variable cylinder engine, which is equipped with a valve stop device for stopping the opening/closing operation of a valve, only the valve spring 4 of the valve train equipped with the valve stop device is manufactured from a titanium-based material, and the valve stop device is A valve train structure for a variable cylinder engine, characterized in that the number of windings is reduced and the spring length is made shorter than that of a valve spring 14 of a valve train without a valve spring 14.
