Abstract: A variable valve timing mechanism for an internal combustion engine comprising at least one rotary valve (1) having at least two ports terminating as openings (2, 3) in its periphery, a cylinder head (7) having a bore in which the rotary valve (1) rotates, and a window (6) in the bore communicating with a combustion chamber (8). The openings (2, 3) successively align with the window (6) by virtue of the rotation. The mechanism also comprises a drive mechanism (13) driving the rotary valve (1). The at least two ports (2, 3) of the rotary valve (1) are an inlet port and an exhaust port. The drive mechanism (13) varies the angular velocity of the rotary valve (1) at least within a portion of at least one engine cycle whilst maintaining an average angular velocity over the at least one engine cycle that has a fixed relation to the average angular velocity of crankshaft over the at least one cycle.

Abstract: The invention relates to an internal combustion engine having, a working cylinder (6), means for supplying gas under pressure (8), means for supplying a gas and fuel mixture (8, 9, 34) exhaust valve means (28) and inlet valve means (1, 2). The inlet valve means (1, 2) delivers both gas under pressure and gas and fuel mixture to the working cylinder (6), commencing delivery of the gas under pressure at an earlier stage in the engine cycle to the commencement of delivery of gas and fuel mixture. The inlet valve means (1, 2) delivers gas under pressure to the cylinder (6) at least for a part of the time that the exhaust port (28) is open so as to drive combusted gases out of the cylindrical. The invention also relates to a rotary valve for an engine having a first member (1) of a cylindrical external configuration, a sleeve (2) surrounding the first member (1) and means (4, 5) for rotating the sleeve (2) relative to the first member (1). The first member (1) comprises a plurality of fluid passages (30, 31) and a plurality of apertures (26, 27) allowing communication of each of the passages (30, 31) with the exterior of the first member (1). The sleeve (2) has at least one aperture (25) which aligns with the apertures (26, 27) of the first member on rotation of the sleeve for a certain portion of the engine cycle. The rotary valve is positioned adjacent the cylinder (6) such that a passage of the first member (1) communicates with the cylinder (6) when the associated aperture in the first member is aligned with the aperture (25) in the sleeve.

Abstract: An internal combustion engine (10) with intake valve (26) that may be kept open for a variable amount of time during the combustion cycle depending on operating conditions of the engine. Cam (22) rotates approximately 45.degree. clockwise to depress poppet (26) moving the intake valve to the open position. Cam (22) is held in the open position by lip (25) on seat (23) of the poppet valve. A step motor is used to rotate cam ( 22 ) to an open or closed position. The step motor may be deenergized while the poppet valve is in the open or shut position. In another embodiment the amount the valve is opened may be varied.
