Abstract : An exhaust energy extraction system for a multi-cylinder engine, comprising an axial flow turbine arranged to convert time-spaced exhaust pressure pulses into turbine rotor rotation. Output flow from the axial flow turbine is directed through a diffuser that converts velocity pressure to static pressure; a second radial flow turbine is operated by the steady state flow produced by the diffuser. Any tendency of the diffuser to exert an adverse back pressure on the axial flow turbine is counteracted by a pressure-responsive vent valve that establishes a ceiling on the diffuser pressure.
