Abstract
A method for operating an internal combustion engine includes compressing intake air using a compressor, supplying the compressed intake air to at least one combustion chamber of the engine, operating the at least one combustion chamber to output exhaust gas, and directing the exhaust gas to an inlet of a turbine configured to drive the compressor. The method also includes directing the exhaust gas from an outlet of the turbine to an exhaust system, bypassing at least a portion of the compressed intake air around the at least one combustion chamber, and adjusting a geometry of the turbine from a first configuration to a second configuration. The turbine is in the second configuration when the at least the portion of the compressed intake air is bypassed around the at least one combustion chamber.
