Abstract

A system for controlling the mixture of an air flow and an exhaust gas flow in an engine is disclosed generally comprising an air conduit for the inlet air, which has an exhaust gas inlet passing through the wall thereof for introducing recirculating exhaust gas into the conduit, and a sleeve having an inlet end through which air enters the sleeve and an outlet end through which air exits the sleeve into the conduit, where the sleeve is movable along the conduit to vary the extent to which the outlet end thereof occludes the exhaust gas inlet, thereby regulating the introduction of exhaust gas into the air conduit, which in some embodiments, is completely closed off. In some embodiments, the outlet end of the sleeve is reduced, and certain embodiments include a streamlined body to regulate the air exiting the sleeve.
