SUPERCHARGER ASSEMBLY FOR REGENERATION OF THROTTLING LOSSES AND METHOD OF CONTROL

摘要

An engine assembly is provided that includes an engine throttle and a supercharger placed in series with one another in air flow to the engine. The throttle and supercharger can be controlled so that throttling losses are selectively distributed across the throttle and/or the supercharger. Throttling losses placed across the supercharger can create torque that can be converted to stored energy.

主权项

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 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.
