Clean gas injector

An internal combustion engine, the engine includes an engine block defining a plurality of combustion chambers, comprising:

• an exhaust air system in fluid communication with the plurality of combustion chambers, the exhaust air system having an exhaust air conduit;
• an intake air system in fluid communication with the plurality of combustion chambers, the intake air system having an intake air conduit having a inner diameter defining a intake air flow path, and an intake air compressing device;
• a CGI system extending between the exhaust air system and the intake air system, the CGI system is connected to the intake air system upstream of the intake air compressing device, the CGI system includes a CGI injector having a CGI injector valve, an CGI conduit defining a clean gas flow path, the CGI conduit being disposed within the intake air conduit, the CGI conduit includes an open end portion having an inner surface and an outer surface, the outer surface having a substantially less diameter than the inner diameter of the intake air conduit and the open end portion being formed to restrict the intake air flow;
• and
• an ECM operatively coupled to the internal combustion engine.
