    Q:
    How does the Exhaust Gas Recirculation (EGR) system address the issue of NOx production during lean cruise modes for the 1992 Ford F-250? Posted by Customer
    A:
    The EGR system reintroduces small metered amounts of exhaust gas back into the intake manifold during part throttle and cruise conditions, where it combines with the air/fuel mixture before combustion, lowering combustion temperatures and reducing NOx emissions.

    Q:
    How is the flow rate of the EGR determined, and what is the role of the DPFE (Differential Pressure Feedback) system for the 2009 Lincoln Navigator? Posted by Customer
    A:
    The flow rate of the EGR is determined by the DPFE system, which monitors the pressure across a metering orifice. The DPFE system is more accurate than previous systems as it can account for changes in exhaust back pressure.
