RISImplementation 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 ...
Nonlinear Compensators of Exhaust Gas Recirculation and Variable Geometry Turbocharger Systems using Air Path Models for a CRDI Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the design of modelbased feedforward compensators for exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT) systems using air path models for a commonrail direct injection (CRDI) ...
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 ...
Two-Side Laser Processing Method for Producing High Aspect Ratio Microholes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser microprocessing is a very attractive option for a growing number of industrial applications due to its intrinsic characteristics, such as high flexibility and process control and also capabilities for noncontact ...
