ABSTRACT:
Several embodiments of induction systems for internal combustion engines that improve maximum power and also provide good running at low and medium speeds with a good torque curve throughout the engine speed range. Each embodiment includes a pair of intake passages that serve each chamber of the engine through a respective pair of intake valves. The intake passages are each tuned to serve a different running condition of the engine.
