Abstract
A multiple intake poppet valve array for use with a single charge carrying intake duct to an engine cylinder in a four cycle internal combustion engine to include three or more annular intake poppet valves and annular valve seats (ports) in fluid communication with said duct and said cylinder for opening and sealing said duct, intake valve lifting and closing means, wherein the area of the duct, the total area of the ports, and the area of the open valves are substantially equal for optimum charge flow at a valve lift distance that occurs earlier and that extends duration when compared with a single poppet valve servicing a similar duct.
Claims8
A multiple poppet valve array for use with a single intake duct in a four cycle internal combustion engine comprising:
- three or more poppet valves;
- an engine cylinder;
- a cylinder head having at least one intake duct in fluid communication with said combustion chamber, said intake duct having three or more apertures opening into said engine cylinder, said apertures including poppet valve seats about their perimeter for seating said three or more poppet valves, the total aperture area substantially matching the cross sectional area of said single intake duct, sized as to complement the charge flow characteristics of said duct, the sum of the circumferences of the multiple valve bodies being greater than the duct circumference by a factor of 1.4 or more;
- and
- means for opening and closing each of said poppet valves in communication with said poppet valves.
A multiple poppet valve system for use with a single intake duct in a four cycle combustion engine comprising:
- three or more intake poppet valves;
- an engine cylinder;
- a cylinder head body having a single intake duct for transporting charge and three or more ports in fluid communication with said single duct and said engine cylinder, the cross sectional area of the intake duct being generally equal to the total area of said ports;
- means for lifting and closing said valves in communication with said valves, said lifting means being sized to a lift distance at least to optimize duration during the intake event whereby the total valve open area is generally equal to the total port area.
