ABSTRACT:
A poppet valve for an internal combustion engine, comprising at least two valve stems and a single non circular valve head attached at one end of the valve stems wherein the stems are spacedly parallel to each other. The valve head has an oval or semi-circular peripheral contour for maximum cylinder breathing. The valve stems positively prevent valve head rotation and define a high surface to volume ratio, for increased heat dissipation capacity.
