Description

ABSTRACT:
An intake port for an internal combustion engine comprises a plurality of vanes or fins provided at the rim of the inlet opening, or adjacent the inlet valve seat, for dividing and guiding the flow of fuel-air mixture into the combustion chamber in two counter-rotating swirls for optimum mixing just prior to combustion. The fins are divided into groups which direct the flows substantially oppositely into the combustion chamber and each said group is subdivided into groups of fins which further direct the flow from each group into different patterns which combine to produce the counter-rotating swirls.
