The turbocharger is designed to increase the overall power and efficiency of the engine. Power to drive the turbocharger is extracted from the energy in the engine exhaust gas.
A turbocharger can be broken down into 3 basic pieces; a compressor cover, a center housing rotating assembly (CHRA), and a turbine housing.
The compressor cover is an aluminum alloy casting that encloses the compressor wheel and provides a V-band connection for the compressor outlet, and a hose connection for the compressor inlet. The compressor cover is secured to the compressor side of the CHRA.
The CHRA contains a turbine wheel and shaft assembly, piston ring(s), thrust spacer, compressor wheel, and wheel retaining nut. This rotating assembly is supported on two pressure-lubricated bearings that are retained in the center housing by snap rings. Internal oil passages are drilled in the center housing to provide lubrication to the turbine wheel shaft bearings, thrust washer, thrust collar, and thrust spacer.
The turbine housing is a heat-resistant steel alloy casting that encloses the turbine wheel and provides a flanged engine exhaust gas inlet and an axially located turbocharger exhaust gas outlet. The turbine housing is secured to the turbine end of the center housing.
All Series 60G, 60 Hz Genset engines use a model K33 turbocharger, manufactured by 3K turbosystems.
