Claim:
1. An assembly for controlling air flow to an engine having a crankshaft, cylinders and a throttle in a throttle body positioned in air flow to the cylinders, the assembly comprising: a supercharger having a set of rotors in series with the throttle in the air flow to the engine; a load device; and a gear arrangement having a first member operatively connected with the load device, a second member operatively connectable with the crankshaft, and a third member operatively connectable with the supercharger, wherein the gear arrangement is a compounded, dual-planetary gear set having a first and a second ring gear member, a first and a second sun gear member, a common carrier member that supports a first set of pinion gears that mesh with the first ring gear member and the first sun gear member and supports a second set of pinion gears that mesh with the second ring gear member and the second sun gear member, wherein the first member operatively connectable with the load device is the first ring gear member; wherein the second member operatively connectable with the crankshaft is the first sun gear member, and wherein the third member operatively connectable with the supercharger is the second sun gear member; wherein the load device is selectively controllable to vary a speed of rotation of the rotors through the gear arrangement to thereby cause the throttle to open so that a pressure drop across the throttle shifts to the rotors, creating torque on the rotors, throttling losses thereby being regenerated.
