という点で問題を有していた。In an engine having a conventional valve operating mechanism, the air-fuel mixture is sucked by opening the air-fuel mixture intake valve, and after the valve is closed, the plug is ignited together with the rise of the piston. The exhaust valve opens and exhausts after the explosion, but the piston does not physically reach the head part during exhaustion, so complete exhaustion is achieved. Therefore, even if the mixture is sucked while the exhaust gas remains in the combustion chamber, the combustion efficiency is deteriorated. Therefore, although a large amount of energy is obtained, there is a problem in that the fuel consumption is low.

〜図４）[Operation] The crankshaft is actuated by the drive of the starter motor, the piston slid on the cylinder slides up and down, and the camshaft that drives the cam rotates in conjunction with the rotation of the cam chain. When the piston descends, the air-fuel mixture intake valve opens due to the operation of the air-fuel mixture intake valve drive cam, and the air that has passed through the air intake pipe from the air cleaner is mixed with gasoline by the carburetor, and the air-fuel mixture is sucked into the combustion chamber and the piston rises. After closing the valve, the mixture in the combustion chamber is compressed (Fig. 2a,
b) When the ignition plug ignites, an explosive pressure is generated and the piston is strongly pressed down, and the crankshaft via the connecting rod converts the upward / downward sliding operation into rotary motion, and the cam chain drive gear causes the cam chain to move. The air-fuel mixture intake valve drive cam, exhaust valve drive cam (for combustion gas), air intake valve drive cam and exhaust valve drive cam (for air) are driven by the camshaft drive gears interlocking and transmitting their respective rotations to the camshaft.

The camshafts 5 and 9 are operated in conjunction with the rotation of the air-fuel mixture, and the abutment surface a of the air-fuel mixture intake valve drive cam 10 comes into contact with the air-fuel mixture intake valve 14 and descends to open the manifold 12 and open the combustion chamber 22. The air-fuel mixture closes after intake. Subsequently, the piston 2 that has risen due to the crank operation of the connecting rod 18 compresses the air-fuel mixture in the combustion chamber 22 (Fig. 2a,
b), a strong explosive force is generated by ignition of the ignition plug 20, the piston 2 descends, and subsequently, as the piston 2 ascends, the contact surface b of the exhaust valve drive cam 6 contacts the exhaust valve 7 to open the valve. Scavenging is performed at (Fig. 3a, b). However, during scavenging, the upper surface of the piston 2 does not physically reach the cylinder head 26 portion, complete scavenging is not performed, and combustion efficiency is poor. In synchronism with the closing operation of the exhaust valve 7 after exhaust, the contact surface c of the air intake valve drive cam 11 comes into contact with the air intake valve 15 and opens the valve, so that air is taken into the combustion chamber 22 and after intake closes. At the same time as the valve, the contact surfaces D of the exhaust valve 7 and the exhaust valve drive cam 6 contact each other, and as the exhaust valve 7 opens and the piston 2 rises again, the residual gas residue is almost completely scavenged through the exhaust pipe 8. Is performed (Fig. 4a, b).
