In the
concept of downsizing an internal combustion engine, the turbocharger in one of
the key device for reducing emissions while maintaining engine performance.
Turbine as one of the main components in a turbocharger has an important role
in determining the power generated by an internal combustion engine. This paper
presents the development of turbine components in turbocharger and methods of
turbine design optimization. In order to maximize the performance of the
turbine in the turbocharger, a variable geometry turbine (VGT) is used. VGT has
several variations that have been developed such as Active Controlled
Turbocharger (ACT), Passive Controlled Turbocharger (PCT), Variable Nozzle
Turbine (VNT), and Regenerative Electrically Assisted Turbocharger (REAT).
Another thing that can be developed to maximize turbine performance is to use a
double-entry turbine. The double entry turbine has the aim of saving exhaust
gas energy and facilitating cylinder gas exchange. One way to produce efficient
turbine performance is to replace the existing spiral casing on the turbine
with a multi-channel casing (MC). The use of this multi-channel turbine reduces
the best efficiency points (BEP).
