Abstract
An intake valve phase shift in multi-valve engines to enhance air-fuel mixing and optimum combustion at all operating conditions. The intake valve members are independently operated by electro-mechanical actuators or the like, and activated and deactivated by the electronic controller of the engine. A channel or passageway in a diverter member positioned between the two intake ports in the cylinder head allows air and fuel from a closed intake port to be diverted to an open intake port and thus into the combustion chamber. The passageway preferably has a configuration with a certain curvature, orientation and position relative to the diameter of the inlet ports. The curvature is about one-half the diameter D of the inlet port, the passageway is symmetrical from port to port and directs the fuel toward the opposite sides of the ports, and the passageway is positioned about D/4 from the valve seats.
