ABSTRACT:
An intake system includes an intake port having a generally triangularly configured cross section so as to permit intake air to flow at a flow rate higher in an upper half section than in a lower half section, thereby producing vertical turbulence of intake air in a combustion chamber. The intake system further includes another intake port having a generally triangularly configured cross section so as to permit intake air to flow at a flow rate higher on a side of the periphery of the combustion chamber than on a side of the center of the combustion chamber and also at a flow rate higher on an upper side of the combustion chamber than on a lower side of the combustion chamber.
