1. Simulation and validation of in-cylinder combustion for a heavy-duty Otto gas engine using 3D-CFD technique
Master-uppsats, KTH/FörbränningsmotorteknikSammanfattning : Utsläpp från bilar har spelat stor roll de senaste decennierna. Detta har lett till ökad användning av Otto gasmotorer som använder naturgas som bränsle. Nya motordesigner behöver optimeras för att förbättra motorens effektivitet. LÄS MER
2. Virtual Crank Angle based Cylinder Pressure Sensor
Master-uppsats, KTH/FörbränningsmotorteknikSammanfattning : Closed-loop combustion control is an on-going field of research for improving reducing engine emissions and increasing efficiency. Cylinder pressure is a key parameter to monitor for combustion feedback. LÄS MER
3. Virtual Crank Angle based Cylinder Pressure Sensor
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : Closed-loop combustion control is an on-going field of research for improving reducing engine emissions and increasing efficiency. Cylinder pressure is a key parameter to monitor for combustion feedback. LÄS MER
4. Crank Angle Based Virtual Cylinder Pressure Sensor in Heavy-Duty Engine Application
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : The in-cylinder pressure is an important signal that gives information about the combustion process. To further improve engine performance, this information can be used as a feedback signal in a control system. Usually a pressure sensor is mounted in the cylinder to extract this information. LÄS MER
5. Virtual Sensors for Combustion Parameters Based on In-Cylinder Pressure
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Typically the combustion in engines are open-loop controlled. By using an in-cylinder pressure sensor it is possible to create virtual sensors for closed-loop combustion control (CLCC). With CLCC it is possible to counteract dynamic effects as component ageing, fuel type and cylinder variance. LÄS MER
