Abstract:
1. A device for handling and recovering kinetic energy in a turbocharged engine, comprising: a bladed impeller; a reversible engine/generator coupled to the bladed impeller; a fluid conveyor containing the impeller, which co-operates with the impeller to handle and recover the kinetic energy of incoming fluid, the fluid conveyor comprising a convergent spiral of a fluid inlet configured to receive an incoming fluid from a turbocharger compressor turbine output and a divergent spiral of the fluid outlet configured to output said fluid to an engine intake; wherein the bladed impeller is formed with a single series of blades, and wherein said single series of blades are configured to both (1) drive the fluid from the fluid inlet to the fluid outlet when the reversible engine/generator is acting as an engine, and (2) be driven by fluid flowing from said fluid inlet to said fluid outlet when the reversible engine/generator is acting as a generator.
