1. 1. Compressible Flow Modeling with Combustion Engine Applications

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Carl Vilhelmsson; [2017]
   Nyckelord :Compressible; Flow; Modeling; Combustion; Engine; Throttle; EGR; Wastegate; Valves; Gas;

   Sammanfattning : The high demands on low fuel consumption and low emissions on the combustion engines of both today, and the future, is highly dependent on advanced control systems in order to fulfill these demands. The control systems and strategies are based on models which describe the physical system. LÄS MER

3. 2. Modeling and Estimation of Long Route EGR Mass Flow in a Turbocharged Gasoline Engine

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Erik Klasén; [2016]
   Nyckelord :Long Route Low Pressure LR LP EGR SI Gasoline Spark Ignited Engines Modeling Modelling Mass Flow Estimation;

   Sammanfattning : Due to the continuous work in the automobile industry to reduce the environmental impact, reduce fuel consumption and increase efficiency, new technologies need to be developed and implemented in vehicles. For spark ignited engines, one technology that has received more attention in recent years is long route Exhaust Gas Recirculation (EGR), which means that exhaust gases after the turbine are transported back to the volume before the compressor in the air intake system of the engine.

4. 3. Modeling of Fuel Dynamics in a Small Two-Stroke Engine Crankcase

   Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Författare :Johan Andersson; Oscar Wyckman; [2015]
   Nyckelord :Modeling; Event based modeling; Two-stroke engines; Crankcase; Fuel dynamics; Wall wetting; Gas mixing;

   Sammanfattning : For any crankcase scavenged two-stroke engine, the fuel dynamics is not easily predicted. This is due to the fact that the fuel has to pass the crankcase volume before it enters the combustion chamber. LÄS MER

5. 4. Modeling, Simulation and Control of Long and Short Route EGR in SI Engines

   Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Författare :Junting Qiu; [2015]
   Nyckelord :Mean value engine modeling; EGR; long route; short route; residual gas fraction; PID;

   Sammanfattning : Modern engines are faced with increasingly stringent requirements for reduced fuel consumptionand lower emissions. A technique which can partly be used to reduce emissionsof nitrogen oxides is recirculation of combusted gases (Exhaust Gas Recirculation, EGR). LÄS MER

7. 5. Mean Value Model of the Gas Temperature at the Exhaust Valve

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

   Författare :Filip Ainouz; Jonas Vedholm; [2009]
   Nyckelord :medelvärdesmodell; avgasventilen; avgastemperatur;

   Sammanfattning : Over the years many investigations of the gas temperature at the exhaust valve have been made. Nevertheless the modeling of the gas temperature still remains an unsolved problem. LÄS MER
