ABSTRACT:
An essentially all ceramic turbocharger for boosting the pressure of air inducted by an internal combustion engine has a housing made in two segments from ceramic material that define exhaust gas inlet and outlet passages and air inlet and outlet passages. A rotary unit formed of ceramic material is formed integrally with a turbine rotor and compressor rotor at opposite ends of the driveshaft. The driveshaft is supported within the housing on ceramic ball bearings whose races are surfaces formed on the driveshaft and housing segments within which ceramic radial and thrust bearings are fitted.
