摘要:
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.

A method of making a duo density article of silicon nitride is disclosed. A first element is formed by hot pressing silicon nitride particles. The general shape of a second element is formed by injection molding silicon metal particles and a binder and subsequently burning out the binder. The second element is nitrided in a nitriding operation. Facing surface areas of the first element and the second element are bonded together by applying heat to both elements and pressure to one of the elements while the other element is held in a fixed position.

A thin outer metallic housing surrounds and is spaced from a one-piece cylindrical ceramic liner that insulates, supports and houses high temperature and rotating parts of the engine, the end faces of the liner constitute rubbing seal surfaces against which are directly mounted ceramic core rotating regenerators, the liner and housing having aligned holes through which is mounted the inline hot gas flow path components.
