Long-route egr system

An exhaust gas recirculation (EGR) system for an internal combustion engine, comprising:

• an exhaust conduit configured to receive exhaust gas from the internal combustion engine;
• an exhaust aftertreatment system disposed in the exhaust conduit;
• a junction coupled to the exhaust conduit for receiving the exhaust gas therefrom and located downstream of at least a portion of the aftertreatment system from the internal combustion engine;
• an EGR conduit connected with the junction and configured to recirculate a portion of the exhaust gas to an intake side of the internal combustion engine;
• a tailpipe connected to the junction and configured to discharge at least a portion of the exhaust gas to atmosphere;
• and
• a control valve disposed at the junction with a valve plate in the control valve configured to control entry of the exhaust gas into the EGR conduit and the valve plate configured to throttle entry of the exhaust gas into the tailpipe.
• a control valve disposed at the junction and having a valve plate operably configured to control entry of the exhaust gas into the EGR conduit and to throttle entry of the exhaust gas into the tailpipe.

An exhaust gas recirculation (EGR) system for an internal combustion engine, comprising:

• a turbine configured to receive exhaust gas from the internal combustion engine;
• a compressor connected with the turbine and configured to charge combustion air supplied to the internal combustion engine, the compressor having an inlet end configured to receive the combustion air;
• an intake duct connected with the compressor and configured to supply the combustion air to the inlet end;
• an exhaust conduit configured to receive the exhaust gas from the turbine;
• a junction coupled to the exhaust conduit for receiving the exhaust gas therefrom;
• an EGR conduit connected with the junction and configured to recirculate a portion of the exhaust gas to an intake side of the internal combustion engine through the compressor;
• a tailpipe connected with the junction and configured to discharge at least a portion of the exhaust gas to atmosphere;
• and
• a control valve disposed at the junction with a valve plate configured to control entry of the exhaust gas into the EGR conduit and the valve plate configured to throttle entry of the exhaust gas into the tailpipe.
• a control valve disposed at the junction and having a valve plate operably configured to control entry of the exhaust gas into the EGR conduit and to throttle entry of the exhaust gas into the tailpipe.
