  • Direct port rotary valve mechanism with variable timing for internal combustion engines
    Patent number: 6691664
    Abstract: Disclosed is a variably timed rotary valve mechanism for controlling the air/fuel intake into and exhaust gases out of an internal combustion engine. There are two rotary valve shafts, one intake and one exhaust, that contain two intake and two exhaust valve ports per engine cylinder. These rotary valve shafts are driven by and synchronized with the engine crankshaft via a conventional timing belt. The timing of each of these rotary valve shafts relative to the crankshaft can be varied individually through hydraulic servomotors under control of a computerized engine management system.
