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 ...

In a gasoline engine, the unswept in-cylinder residual gas and introduction of external EGR is one of the important means of controlling engine raw NOx emissions and improving part load fuel economy ...

All 2005-07 Acura RL sedans, in addition to 2008 models built from VIN JH4KB16..8C000001 through JH4KB16..8C004681, may turn on the check engine light and store DTC P0401 (insufficient EGR flow) in ...

The paper presents an original review and extension of existing mathematical models for on-line residual gas fraction estimation. The resulting model has first of all been extended to take into ...

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).
