Zusammenfassung:An improved induction system for an internal combustion engine that improves power throughout the entire speed and load ranges by including two plenum chambers, having separate intake passage that serve the cylinders of the engine. One plenum chamber and its intake passages is designed to improve low and midrange performance while the other plenum chamber and its intake passage is tuned for high speed performance. An atmospheric air inlet is provided only for the latter plenum chamber and the first mentioned plenum chamber receives its atmospheric air from this plenum chamber through a connecting passageway.
