EGR performance balancing restrictor for an engine system

An exhaust gas recirculation performance balancing restrictor being installed in an engine system, the engine system including an internal combustion engine having an intake manifold and an exhaust manifold, an intake air conduit extending from an air inlet to the intake manifold, an exhaust conduit extending from the exhaust manifold to an exhaust outlet and having a pressure sensor therein, the exhaust gas recirculation conduit having the inlet in fluid communication with the exhaust conduit and an outlet in fluid communication with the intake air conduit, and an aftertreatment component disposed along the exhaust conduit downstream from the inlet of the exhaust gas recirculation conduit, wherein the exhaust conduit defines a first backpressure at the inlet of the exhaust gas recirculation conduit prior to installation of an exhaust gas recirculation performance balancing restrictor, the exhaust gas recirculation performance balancing restrictor comprising:

• a disk-shaped body;
• a fixed orifice through the disk-shaped body defining a reduced exhaust flow area that is less than a flow area defined by the exhaust conduit;
• and
• a periphery of the disk-shaped body defining an outer diameter substantially equal to an inner diameter of the exhaust conduit;
• wherein the exhaust gas recirculation performance balancing restrictor has an installed position wherein the exhaust gas recirculation performance balancing restrictor is removably disposed within the exhaust conduit downstream from the inlet of the exhaust gas recirculation conduit and provides a fixed flow restriction through the exhaust conduit to generate a second backpressure at the inlet of the exhaust gas recirculation conduit which is greater than the first backpressure.
