Abstract: In an internal combustion engine in which intake and exhaust rotary valves each having a spherical valve body are controlled in opening and closing through a valve operating mechanism interlockingly with the movement of a piston, the intake and exhaust rotary valves (10, 20; 110, 120; 210, 220; 310, 310', 320, 320') respectively assume the fully opened positions to open intake and exhaust passages (7, 8; 107, 108; 207, 208; 307, 307', 308, 308'), during the intake and exhaust strokes of the engine (1; 101; 201; 301), and assume the fully closed positions during the explosion stroke. In the fully opened and closed positions, the intake and exhaust rotary valves (10, 20; 110, 120; 210, 220; 310, 310', 320, 320') are held at a stop state for a predetermined period of time by the intermittently operating function of the valve operating mechanism (30; 130; 230; 330).

Abstract: An improved exhaust port throttling mechanism for a two-stroke engine. The engine includes a plurality of in-line cylinders (2) each having an exhaust passage (5) disposed to be closed during reciprocating movement of the piston. The exhaust passages (5) communicate with a common exhaust chamber (6a, 6b) and a tubular valve member (10) is mounted for rotation within the exhaust chamber (6a, 6b). The valve member (10) includes a plurality of apertures (13), each adapted to register with one of the exhaust passages (5). When used with a V-6 engine having two banks of in-line cylinders (2), a shaft (12) is connected to each valve member (10) and the corresponding ends of the shafts are interconnected by meshing gear segments (15a-15b). One of the gear segments (15a) is connected through a linkage (27) to the throttle lever (28) for the engine (1) so that the valve members (10) will be rotated by actuation of the throttle lever (28) between a substantially closed position at low speeds, where the valve members (10) substantially close off the exhaust passages, to an open position at high speed where the apertures (13) in the valve members (10) are in full registery with the exhaust passages (5), so that the exhaust gas is discharged via the interior of the valve members (10) without restriction.

Abstract: An internal combustion engine has a stator passage leading to a cylinder. An intake poppet valve is disposed between the cylinder and stator passage, and a rotary valve adjoins the opposite end of the stator passage. The rotary valve has a rotor with an elongated tapered rotor passage partially in registration with the stator passage. The rotor is driven by the crankshaft and is adjustable in phase to vary the time of opening and closing of the rotary valve, and is axially shiftable to vary the valve opening duration. A control system responsive to engine speed and load independently varies the rotary valve phase and duration for optimum engine operation.
