Abstract
A number of embodiments of V-type internal combustion engines having an induction system which provides variable length sections for serving each combustion chamber, with each section being tuned to provide optimum charging efficiency for a different engine running speed. In addition, a flow-controlling valve is provided in the induction passages adjacent the combustion chamber and is movable between a nonrestricting flow position and a position wherein the flow is redirected to generate turbulence in the combustion chamber. The induction system is designed so as to provide a compact assembly and yet permit efficient induction and combustion under a wide range of engine speed and load conditions.
