RISFault Diagnosis of Exhaust Gas Recirculation and Variable Geometry Turbocharger Systems in a Passenger Car Diesel Engine Based on a Sliding Mode Observer for Air System States Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we propose a sliding mode observer based fault diagnosis algorithm for diesel engines with exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT) systems. The nonlinear sliding mode observer ...
Robust Indicated Mean Effective Pressure and Combustion Lambda Feedback Control for Lean NOx Trap Regeneration in a 2.2 L Common Rail Direct Injection Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To meet stringent Euro6 emission regulations, a lean NOx trap (LNT) catalyst should be considered to effectively abate NOx emissions. This LNT catalyst should be periodically regenerated without deteriorating driving quality ...
Cylinder Pressure Information Based Postinjection Timing Control for Aftertreatment System Regeneration in a Diesel Engine—Part I: Derivation of Control Parameter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The implementation of aftertreatment systems in passenger car diesel engines, such as a lean NOx trap (LNT) and a diesel particulate filter (DPF), requires an incylinder postinjection (POI) for a periodic regeneration of ...
Exhaust Pressure Estimation Using a Diesel Particulate Filter Mass Flow Model in a Light Duty Diesel Engine Operated With Dual Loop Exhaust Gas Recirculation and Variable Geometry Turbocharger Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel method to estimate an exhaust pressure at 357 different steadystate engine operating conditions using a diesel particulate filter (DPF) mass flow model to precisely control the air quantity for ...
Cylinder Pressure Information Based Postinjection Timing Control for Aftertreatment System Regeneration in a Diesel Engine—Part II: Active Diesel Particulate Filter Regeneration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The successful utilization of a diesel particulate filter (DPF) to reduce particulate matter (PM) in a passenger car diesel engine necessitates a periodic regeneration of the DPF catalyst without deterioration of the ...
