Disclosed is high torque traction drive. The high torque traction drive utilizes planet gears that engage the inner mesh of a ring gear. The planet gears are mounted in rollers that have inner traction surfaces that engage sloped ring traction surfaces on traction rings that are attached to the ring gear. The sloped traction interface causes the rollers to move inwardly when forced toward the traction rings. The inward force on the rollers creates a shaft traction interface between a shaft and outer traction surfaces on the roller, so that rotational mechanical energy is effectively transferred between the rollers, the shaft and the ring gear. High rotational speeds can be achieved with a high degree of torque. Speed reduction ratios of at least 10:1 or greater can be achieved. The high speed drive may include exhaust turbines, steam turbines, including a Tesla turbine or Schumacher turbine, compressors, combinations of turbines and compressors, high speed pumps, dentist drills, or other devices that operate with high rotational speed.
Disclosed is a super-turbocharger system (100) that increases power and efficiency of an engine (102). The system uses the exothermic properties of a catalytic converter (116) to extract additional energy from exhaust heat that is used to add power to the engine. Compressed air is supplied and mixed with exhaust gases upstream and/or downstream from a catalytic converter (116) that is connected to an exhaust manifold. The gaseous mixture of exhaust gases and compressed air is sufficiently rich in oxygen to oxidize hydrocarbons and carbon monoxide in the catalytic converter (116), which adds heat to the gaseous mixture. In addition, a sufficient amount of compressed air is supplied to the exhaust gases to maintain the temperature of the gaseous mixture at a substantially optimal temperature level. The gaseous mixture is applied to the turbine (106) of the super-turbocharger, which increases the output of said super-turbocharger, which increases the power and efficiency of said engine (102).
Disclosed is a control system and method for controlling a superturbocharged engine system in various operation modes. Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For transient control mode, the control system may respond to transient conditions in response to engine speed and load so that the engine does not bog down or overcome vehicle traction limits. The control system may also predict future operating points.

Disclosed is a symmetrical traction drive that utilizes multi-diameter rollers having traction surfaces for transferring rotational mechanical energy between the shaft and a transfer gear. Multi-diameter rollers are mounted in carriers disposed between two substantially symmetrical ring gears.

Since force is applied to the inner traction surfaces on both sides of the multi-diameter rollers, forces are substantially equalized on each side of the multi-diameter rollers.

Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For steady state control mode, the control system may receive a plurality of input data, an actual/current control data input, look up a desired value for the control input, compare the desired to the actual control input, and perform control logic on the comparison results to obtain an updated continuously variable transmission ratio to control the superturbocharged engine system independent of throttling on the engine.

A second traction drive provides infinitely variable speed ratios through a continuously variable transmission. Gas recirculation in a super-turbocharger is also disclosed.
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.
