Turbocharger having variable compressor trim

A turbocharger for receiving exhaust gas from an internal combustion engine and for delivering compressed air to the internal combustion engine, said turbocharger comprising:

• a turbine housing defining a turbine housing interior;
• a turbine wheel disposed within said turbine housing interior for receiving the exhaust gas from the internal combustion engine;
• a turbocharger shaft coupled to and rotatable by said turbine wheel, with said turbocharger shaft extending along an axis that extends longitudinally through said turbine housing interior;
• a compressor housing defining an interior, with said compressor housing having an air inlet portion spaced from said turbocharger shaft and disposed about said axis, and with said air inlet defining an inlet diameter (ID) perpendicular to said axis;
• a compressor wheel disposed within said interior and coupled to said turbocharger shaft, with said compressor wheel being rotatable by said turbocharger shaft for delivering compressed air to said air inlet portion and said turbine wheel;
• and
• an airflow adjustment assembly comprising,
• a plurality of guide vanes at least partially disposed within said interior of said compressor, with each of said plurality of guide vanes having a guide tip and a guide base spaced from said guide tip along said axis, with each of said guide bases pivotably coupled to said air inlet portion, and with each of said guide tips defining a vane diameter (VD) less than said inlet diameter (ID) and perpendicular to said axis,
• a sliding ring at least partially disposed within said interior of said compressor and axially moveable along said axis, and
• a plurality of connecting rods at least partially disposed within said interior of said compressor, with each of said plurality of connecting rods disposed between and coupled to one of said plurality of guide vanes between said guide base and said guide tip and said sliding ring;
• wherein said plurality of connecting rods are axially moveable along said axis when said sliding ring moves axially along said axis, thereby selectively increasing and/or decreasing said vane diameter (VD) when said sliding ring moves axially along said axis.
