Abstract
Disclosed is a system and method that increases the amount of power available from a super-turbocharger, and the fuel efficiency of an engine. The system utilizes a catalytic converter to provide thermal buffering to the turbine protecting it from thermal transients. Since the catalytic converter is exothermic, a portion of the compressed air generated by the compressor is fed back to the turbine via a feedback valve decreasing the exhaust temperature and increasing the mass flow provided to the turbine. The feedback valve can be used to reduce compressor surge during low rpm, high load conditions of said engine. The amount of compressor feedback air is limited to the amount of excess thermal energy so that an optimum turbine operating temperature of the combined engine exhaust gas and compressed air can be maintained. Excess power generated by the turbine is then used to drive the engine crank shaft.
