SUPER-TURBOCHARGER HAVING A HIGH SPEED TRACTION DRIVE AND A CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A super-turbo charger utilizing a high speed, fixed ratio traction drive that is coupled to a continuously variable transmission to allow for high speed operation is provided. A high speed traction drive is utilized to provide speed reduction from the high speed turbine shaft. A second traction drive provides infinitely variable speed ratios through a continuously variable transmission. Gas recirculation in a super-turbocharger is also disclosed.
