EGR Valve: Description and Operation
Description and Operation
The Pressure Feedback Electronic (PFE) EGR valve is a conventional ported EGR valve with a backpressure sensing tube attached to it. The valve is
used in conjunction with a pressure transducer (9J460) which supplies pressure feedback to the EEC-IV processor. The EGR flow rate is proportional to
the pressure drop across a remotely mounted sharp edged orifice.
