ABSTRACT:
An improved control valve arrangement for an internal combustion engine that includes a staged, separately tuned induction system and an exhaust system that contains an exhaust control valve. The exhaust control valve is adjusted to provide different reflective areas for the exhaust system under conditions when each of the separately tuned induction systems is operating outside of its peak efficiency point so as to improve the torque curve of the engine.
