MULTI-CYLINDER INTERNAL COMBUSTION ENGINE HAVING SELECTIVE CYLINDER CONTROL

摘要

A MULTI-CYLINDER INTERNAL COMBUSTION ENGINE HAVING SELECTIVE CYLINDER CONTROL A multi-cylinder internal combustion engine having valve train operated intake and exhaust valves for each cylinder and a valve control system adding the capability of automatic selection as to whether or not given cylinders are to be in operation. The cylinders that are to be controlled are identified and movable interposers are installed for both the intake and exhaust valves of the selected cylinders. Control rods interconnect intake interposers to each other and exhaust interposers to each other. A combined actuation arm and interconnection link is provided to transfer motion from a selection actuator to the control rods. A mechanical interlock ensures that exhaust valves are not deactivatable until deactivation of the intake valves occurs.
