In an attempt to control vehicle exhaust emissions, Ford advanced their EGR systems with the introduction of the EGR position sensor. This gave the ECM some idea of how much exhaust gas was being ...

Two critical elements that need to be checked out at 100,000 miles are the EGR valve and the DPF. Hasten says to run a computerized flow test on the DPF filter tol show if the filter in the exhaust ...

ABSTRACT EGR is a proven technology used to reduce NOx formation in both compression and spark ignition engines by reducing the combustion temperature. In order to further increase its efficiency the ...

Abstract: This paper describes a pressure and flow based control method of diesel engine air-path systems equipped with dual-loop exhaust gas recirculation (EGR) and variable geometry turbine (VGT).
