RISRobust 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 ...
Implementation of Optimized Artificial Neural Networks for Real-Time Estimation of Low Pressure Cooled Exhaust Gas Recirculation in a Turbocharged Gasoline Direct Injection Engine Using a Model-Based Design Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low pressure cooled exhaust gas recirculation (LP-EGR) system has been widely adopted to improve energy efficiency in turbocharged gasoline direct injection (GDI) engines. In order to utilize complete beneficial effects ...
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 ...
Fault Management System of LP-EGR Using In-Cylinder Pressure Information in Light-Duty Diesel Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particulate matters (PM) accumulation through a low-pressure exhaust gas recirculation (LP-EGR) path may hinder to obtain the desired LP-EGR rate and thus causes an increase of nitrogen oxides (NOx). The degree of lack of ...
Estimation of Intake Oxygen Concentration Using a Dynamic Correction State With Extended Kalman Filter for Light-Duty Diesel Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate estimation of the intake oxygen concentration (IOC) is a prerequisite to develop the optimal control strategy because it directly affects the combustion and emissions. Since the IOC is determined based on the ...
Set-Point Adaptation Strategy of Air Systems of Light-Duty Diesel Engines for NOx Emission Reduction Under Acceleration Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern diesel engines equip the exhaust gas recirculation (EGR) system because it can suppress NOx emissions effectively. However, since a large amount of exhaust gas might cause the degradation of drivability, the control ...
In-Cylinder Pressure-Based Low-Pressure-Cooled Exhaust Gas Recirculation Estimation Methods for Turbocharged Gasoline Direct Injection Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes three different methods to estimate the low-pressure cooled exhaust gas recirculation (LP-EGR) mass flow rate based on in-cylinder pressure measurements. The proposed LP-EGR models are designed with ...
