T- TPL77 turbocharger nozzle ring is one part of T- ABB / T- TPL-A series turbocharger with the design features as below:
The T- TPL-A series turbocharger is for large medium-speed diesel and gas engines,with a power output range from 2,500kW to 12,500kW.
Turbine: The T- TPL-A turbocharger is axial turbine for high efficiencies and high volume flow rates.
Compressor: The T- TPL-A comressors ensure the high volume flow rates which allow optimized matching to different engine applications. Its single-piece, splitter-bladed aluminum alloy wheels with backswept blades ensure high efficiencies and wide compressor maps. its pressure ratio is from 4.2 up to 5.0 based on different design.
Bearing: The T- TPL-A bearing assembly lubricated directly by the engine lube oil system, plain bearings can run up to 36,000 hours before being overhauled.

Note: *includes filter silencer.
The turbine is driven by the engine exhaust gas, which enters via the gas inlet casing. The gas expands through a nozzle ring where the pressure energy of the gas is converted to kinetic energy. This high velocity gas is directed onto the turbine blades where it drives the turbine wheel, and thus the compressor at high speeds (10 -15000 rpm). The exhaust gas then passes through the outlet casing to the exhaust uptakes.
