  • EGR performance balancing restrictor for an engine system
    Patent number: 8783028
    Abstract: An engine system includes an exhaust gas recirculation conduit having an inlet in fluid communication with an exhaust conduit and an outlet in fluid communication with an intake air conduit. An exhaust gas recirculation performance balancing restrictor has an uninstalled position wherein the exhaust conduit defines a first backpressure at the inlet of the exhaust gas recirculation conduit. The exhaust gas recirculation performance balancing restrictor also has an installed position in which the exhaust gas recirculation performance balancing restrictor is removably disposed within the exhaust conduit downstream from the inlet of the exhaust gas recirculation conduit. In the installed position, the exhaust gas recirculation performance balancing restrictor provides a fixed flow restriction through the exhaust conduit to generate a second backpressure at the inlet of the exhaust gas recirculation conduit that is greater than the first backpressure.
