SuperGen - TSG

SuperGen-TSG (Turbocharger+SuperGen) combines SuperGen's supercharging and hybridisation advantages with the additional benefits of multi-stage turbocharging.

TSG is fundamentally different to other Super-Turbo systems in that the SuperGen supercharger is installed between a conventional 'low-pressure' Turbocharger and the engine - in effect SuperGen is the high-pressure compressor stage, and only the LP-turbocharger operates in the exhaust system.

The result is a two-stage, very high boost-performance, efficient, scalable and on-demand electro-mechanical hybrid charging system particularly suited to next generation gasoline and Diesel engines.

In cost, engine power & torque, economy, response and flexibility the TSG system compares extremely favourably with other boosting technology competitors.
