1. 1. A GENeric Internal Combustion Engine model : LiU-Genie

   University essay from Linköpings universitet/Fordonssystem

   Author : Oskar Lind Jonsson; [2021]
   Keywords : ;

   Abstract : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. READ MORE

3. 2. Exhaust Temperature Modeling and Optimal Control of Catalytic Converter Heating

   University essay from Linköpings universitet/Fordonssystem

   Author : Victor Petersson; [2019]
   Keywords : cold-start; catalyst heating; ignition retardation; GDI;

   Abstract : After reaching its light-off temperature, the catalytic aftertreatment system plays a major part in maintaining emissions at low levels for vehicles equipped with combustion engines. In this thesis, modelling of the exhaust gas temperature is investigated along with optimal control strategy for variable ignition and exhaust valve opening angles for optimal catalytic converter heating.

4. 3. Compressible Flow Modeling with Combustion Engine Applications

   University essay from Linköpings universitet/Fordonssystem

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

   Abstract : 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. READ MORE

5. 4. Model Based Control of Throttle, EGR and Wastegate : A System Analysis of the Gas Flows in an SI-Engine

   University essay from Linköpings universitet/Fordonssystem

   Author : Henrik Andersson; [2017]
   Keywords : Model; Control; SI-engine; gas-flow; system analysis;

   Abstract : Due to governmental requirements on low exhaust gas emissions and the drivers request of fast response, it is important to be able to control the gas flow in a spark ignited engine accurately. The air into the cylinder is directly related to the torque generated by the engine. READ MORE

6. 5. Boost Control with Turbo Speed Sensor and Electric Wastegate

   University essay from Linköpings universitet/Fordonssystem

   Author : Robin Holmbom; Bohan Liang; [2016]
   Keywords : Turbo Speed Sensor; Boost Control; Electric Wastegate;

   Abstract : The purpose of this master thesis is to investigate the possibility to refine the control system of turbochargers in petrol engines by introducing turbo speed measurement. This thesis also investigates possible control enhancement from an electric wastegate actuator compared with a traditional pneumatic actuator. READ MORE
