摘要： A rotary valve internal combustion engine has a piston (1) connected to a crankshaft (3) and reciprocatable in a cylinder (2), a combustion chamber 4 being defined in part by the piston. The engine has a rotary valve (5) rotatable with a close sliding fit in a valve housing (8) fixed relative to the cylinder (2), the rotary valve having a valve body containing a volume (9) defining, in part, the combustion chamber 4 and further having in a wall part (11) thereof a port (1)2 giving, during rotation of the valve, fluid communication successively to and from the combustion chamber via inlet and exhaust ports (13), (14) in the valve housing. The rotary valve and the valve housing are both formed of aluminium.

摘要： A spark ignition rotary valve internal combustion engine includes a combustion chamber being defined in part by the piston and the combustion end of the cylinder, a valve housing fixed at an outer portion of the combustion end of the cylinder and defining a bore, and a rotary valve rotatable about a rotary valve axis in the bore in the valve housing. The rotary valve has a hollow valve body subjected to combustion gases throughout the combustion process. The rotary valve also has, in a wall part thereof, a port giving, during rotation of the valve, fluid communication successively to and from the combustion chamber via inlet and exhaust ports in the valve housing. The inlet and exhaust ports are angularly offset with respect to a radial line from the center of the engine cylinder.

摘要： A rotary valve internal combustion engine has a piston connected to a crankshaft, where the piston is reciprocatable in a cylinder, and a combustion chamber being defined in part by the piston. The engine has a rotary valve rotatable in a valve housing fixed relative to the cylinder, the rotary valve having a valve body containing a volume defining, in part, the combustion chamber and further having in a wall part thereof a port giving, during rotation of the valve, fluid communication successively to and from the combustion chamber via inlet and exhaust ports in the valve housing. The valve body has a non-uniform radial profile along its axial length and/or about its axis of rotation to accommodate changes in the profile of the valve body during operation to maintain a substantially constant clearance between the valve body and the housing throughout the length of the valve body.
