Abstract
A system and method are provided to control a turbocharger by fluidic control of engine exhaust by steering the same. The system and method include fluidic control of engine exhaust flow directed toward an expander section of the turbocharger, wherein one of position or velocity is effectively varied by a small stream of a fluid in fluid communication with the exhaust gas flow thereby varying the drive of a compressor section of the turbocharger.
Claims22
A method for controlling a turbocharger of an engine, the method comprising:
- steering engine exhaust that is directed in a first direction toward an expander section of the turbocharger in a second direction that varies the ability of said engine exhaust to drive a compressor section of the turbocharger,
- wherein said steering includes using a small stream of fluid in fluid communication with said engine exhaust in said expander section to provide fluidic control of a larger stream of said engine exhaust, thereby fluidically redirecting a portion of said engine exhaust from said first direction to said second direction.
A power plant system for turbocharging an engine, said system comprising:
- a turbocharger for increasing air pressure above ambient air pressure to the engine;
- and
- a control system configured for producing a small stream of fluid operably configured to steer engine exhaust that is directed in a first direction toward an expander section of the turbocharger in a second direction that varies the ability of said engine exhaust to drive a compressor section of the turbocharger,
- wherein said small stream of fluid is in fluid communication with said engine exhaust in said expander section, and is configured to provide fluidic control of a larger stream of said engine exhaust, thereby fluidically redirecting a portion of said engine exhaust from said first direction to said second direction.
