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.
