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 ...

Volvo developed Precision Flow exhaust-gas recirculation (EGR) to improve fuel economy by 3 percent even as they met EPA's 2007 emissions standards for on-road diesel engines. An electronic ...

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).
