Definitions

  • the present invention has been accomplished in view of the background, and the invention provides a turbocharger capable of preventing the accumulation of deposits in the diffuser passage.
  • the bearing housing includes a bearing body and a back plate which is disposed between the bearing body and the compressor housing and which faces to a portion of the air flow path, the bearing body and the back plate are separated from each other, and the back plate may be provided with the facing surface.
  • the back plate which is a portion of the bearing housing with the cleaning agent supplying unit.
  • sintered metal made of porous stainless steel is used as porous material configuring the porous supplying portions 41 and 51.
  • SUPER-CHECK CLEANING AGENT produced by MARKTEC Corporation is used as the cleaning agent 6.
  • the cleaning agent supplying units 4 and 5 are configured such that a temperature of compressed air becomes high (e.g., 165°C or higher) in the diffuser passage 15, and vaporized cleaning agent 6 of a necessary amount is supplied at a temperature (lower than the above temperature by 5 to 10°C) slightly lower than a temperature at which oil from a PCV becomes deposits and the deposits adhere to the diffuser surface 222 of the compressor housing 2 or the facing surface 311 of the bearing housing 3.
  • the cleaning agent supplying units 4 and 5 may be configured such that if an atmosphere temperature of the turbocharger 1 (on the side of compressor) becomes equal to or higher than a predetermined temperature, the liquid cleaning agent 6 held in the pores in the porous supplying portions 41 and 51 are vaporized and supplied to the diffuser surface 222 of the compressor housing 2 and the facing surface 311 of the bearing housing 3.
  • the back plate 31 of the bearing housing 3 is provided with the cleaning agent supplying unit 5.
  • the porous supplying portion 51 is disposed in the annular recess 34 provided in the facing surface 311 of the back plate 31.
  • the reservoir 52 and outside are in communication with each other through the external communication passage 53 provided in the back plate 31.
  • Other basic structure is the same as that of the first embodiment.
