2. 1. Model Based Optimization of a Complete Diesel Engine/SCR System

   Author : Claes Ericson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; model based optimization; real time models; model based control; SCR; optimization; EGR;

   Abstract : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.

4. 2. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines

   Author : Xavier Llamas; Lars Eriksson; Gerasimos Theotokatos; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Modeling for control; Ship Propulsion; Dynamic Simulation; Exhaust Gas Recirculation; Mean Value Engine Model; Parameterization; Compressor; Model Extrapolation;

   Abstract : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.

5. 3. Control of EGR and VGT for emission control and pumping work minimization in diesel engines

   Author : Johan Wahlström; Lars Nielsen; Lars Eriksson; Tore Hägglund; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean value modeling; Oxygen fuel ratio; EGR-fraction; System analysis; Sign reversal; PID-control; European Transient Cycle; Automatic control; Reglerteknik;

   Abstract : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. READ MORE

6. 4. Modeling Complex Engines as Dynamic Powertrain Members

   Author : Sixten Berglund; Chalmers University of Technology; []
   Keywords : vehicle; diesel engine; simulation; supercharging; drivability; toolbox; fuel economy; transient; modeling; turbocharging; control system; powertrain; emissions; performance; dynamic; system;

   Abstract : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. READ MORE

7. 5. Diagnosability performance analysis of models and fault detectors

   Author : Daniel Jung; Erik Frisk; Mattias Krysander; Michael Hofbaur; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Fault isolation; FDI; Kullback-Leibler divergence; Engine misfire detection;

   Abstract : Model-based diagnosis compares observations from a system with predictions using a mathematical model to detect and isolate faulty components. Analyzing which faults that can be detected and isolated given the model gives useful information when designing a diagnosis system. READ MORE
