Abstract
Exhaust gas turbochargers used in the automobiles, such as passenger vehicles, commercial vehicles and off-road engines, have some discrepancies to the heavy turbomachines applied to the power plants and chemical industries. The automotive turbochargers are much smaller and operate at high rotor speeds in various operating conditions, such as variable rotor speeds, pressures, temperatures, and mass flow rates. Contrary to the automotive turbochargers, industrial turbomachines are larger, heavier, and mostly operate at stationary conditions. They operate mostly between 3000 and 20,000 rpm since the compressor and turbine wheels are very large compared to the turbochargers. Due to their much smaller wheels, the automotive turbochargers could operate at very high rotor speeds from 100,000 to 400,000 rpm.
