Apparatus for the feedback of exhaust gases in an internal combustion engine

摘要

An internal combustion engine has an intake gas conduit; an output setting member disposed in the intake gas conduit and arranged for controlling therein the flow of intake gas; an exhaust gas conduit; a throttle member disposed in the intake gas conduit upstream of the output setting member; a bypass conduit having an inlet end coupled to the intake gas conduit upstream of the throttle member and an outlet end coupled to the intake gas conduit downstream of the throttle member; an exhaust gas feedback conduit having an inlet end coupled to the exhaust gas conduit and an outlet end coupled to the bypass conduit; and a control arrangement for setting positions of the throttle member as a function of an operational parameter of the internal combustion engine for directing a quantity of intake air into the bypass conduit as a function of the operational parameter.
