T- NR12/S turbocharger Turbine diffuser is one part for T- / T- NR series turbochargers, which were designed comparatively simply with a cast radial turbine, which is suitable for heavy fuel oil engines, marine diesel oil engines, biofuel and gas operation enginess. Products are available for a wide engine power range, from 450 kW to 5400kW per turbocharger and without compromise in reliability and perforce.
T- NR series turbocharger is widely used in ship building, locomotive, land power station and petroleum drilling industries, extensively applicable to in-land and coastal transportation and fishing due to its high efficiency, small size, light weight, favorable maintainability and serviceability, adequate supply of spare parts.

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.
The diffuser is mounted in the compressor side of the turbocharger in order to direct the air smoothly into volute casing and Convert kinetic energy to pressure energy inlet air.
