Turbocharger egr module

Abstract

A product comprising a turbine torsionally connected to a compressor, a housing for said turbine, a housing for said compressor fixed with respect to said turbine housing, and an exhaust gas recirculation valve mounted on at least one of said turbine or said compressor housings.

1 . A product comprising:
 a turbocharger comprising a turbine torsionally connected to a compressor,   a housing for said turbine,   a housing for said compressor fixed with respect to said turbine housing; and an exhaust gas recirculation valve mounted on at least one of said turbine or said compressor housings wherein there is a low pressure exhaust gas recirculation valve mounted on said compressor housing.   
     
     
         2 . A product as described in  claim 1  wherein there is an exhaust gas recirculation valve mounted on said turbine and said compressor housings. 
     
     
         3 . A product as described in  claim 1  wherein there is a high pressure exhaust gas recirculation valve mounted on said turbine housing. 
     
     
         4 . A product as described in  claim 3  wherein said exhaust gas recirculation v lye is a poppet type valve. 
     
     
         5 . A product as described in  claim 3  wherein said exhaust gas recirculation valve is water cooled. 
     
     
         6 . A product as described in  claim 3  wherein said exhaust gas recirculation valve has a DC motor drive. 
     
     
         7 . A product as described in  claim 3  further comprising a cooler bypass valve mounted to said turbine housing. 
     
     
         8 . (canceled) 
     
     
         9 . A product as described in  claim 1  wherein said exhaust gas recirculation valve has a DC motor drive. 
     
     
         10 . A product as described in  claim 1  wherein said exhaust gas recirculation valve is throttle type valve. 
     
     
         11 . A product as described in  claim 1  further comprising an exhaust gas mixing unit mounted between said compressor housing and said exhaust gas recirculation valve. 
     
     
         12 . A product as described in  claim 1  further comprising an intake valve mounted to said compressor housing. 
     
     
         13 . A product comprising:
 a turbocharger comprising a turbine torsionally connected to a compressor,   a housing for said turbine, a housing for said compressor fixed with respect to said turbine housing, and   a water cooled DC motor drive poppet exhaust gas recirculation valve mounted on said turbine housing; and   a DC motor drive throttle exhaust gas recirculation valve mounted on said compressor housing.
