Abstract: Disclosed is an embodiment of a turbocharger roller support system that utilizes roller-shaft interfaces that are slanted to locate a turbocharger shaft with a turbine and compressor. Slanted contact surfaces on the turbocharger shaft are slanted inwardly so that the turbo shaft remains centered in the roller support system. The rollers entirely locate the turbocharger shaft, so that no bearings are necessary directly on the turbocharger shaft. The rollers spin at a slower speed than the turbocharger shaft, so can utilize lower speed bearings.

Abstract: Disclosed is an air pump for a fuel cell that utilizes a speed-reduction traction drive so that a low speed electric motor can be used to drive a high-speed rotodynamic compressor. The rotodynamic compressor is an efficient air pump, but operates at high speeds that would require a specialized high-speed electric motor. The speed-reduction traction drive couples to the compressor and provides a low-speed output that is connected to a lower speed electric motor.

Abstract: Disclosed is a driven turbocharger for an engine with dual stage compressors. In addition to the turbine and compressor on the main turbo shaft of the driven turbocharger, an additional compressor is coupled to a transfer gear of the driven turbocharger to provide two-stage compression for the engine. This enables higher boost pressures, which can help boost engine efficiency. The driven turbocharger retains the single turbine, so that no additional heat sinks are added to the exhaust to keep exhaust temperatures high for aftertreatment functionality.

Abstract: Disclosed is a speed reduced driven turbocharger that utilizes a step-down roller that is coupled to a turbo shaft with a traction interface. Either a flat or a shaped traction interface can be used. The step-down roller mechanically actuates either a mechanical or hydraulic transmission, or can be mechanically coupled to an electric motor/generator.

Abstract: Disclosed is a super-turbocharger system that increases power and efficiency of an engine. The system uses the exothermic properties of a catalytic converter 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 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, 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 of the super-turbocharger, which increases the output of said super-turbocharger, which increases the power and efficiency of said engine.
