ABSTRACT:
Several embodiments of induction systems for internal combustion engines wherein the effective shape of the intake passage may be changed during engine running conditions to achieve turbulence of the desired type in the combustion chamber and improve volumetric efficiency at low and mid range performance and provide a substantially uninterrupted introduction of charge under high speed running so as to improve the performance throughout the entire engine load and speed ranges. Also, a control valve arrangement is provided in the exhaust system for improving performance under low engine speeds and low engine loads.
