<p>Several embodiments of induction systems for internal combustion engines that improve charging efficiency over a widespread range, particularly at the lower speeds of the engine. Each embodiment includes a plurality of plenum chambers each of which communicates with the intake passage of the engine between the throttle valve and the served chamber. In one embodiment, the plenum chambers communicate with the induction system through separate branch passages. In other embodiments, the plenum chambers communicate with the induction system through each other.</p> |
