1. 1. Modelling and Optimal Control of a Variable Nozzle Turbine in an SI Engine for Maximum Performance

   University essay from Linköpings universitet/Fordonssystem

   Author : Emil Fransson Brunberg; Karl Bolin; [2022]
   Keywords : Variable nozzle turbine; VNT; Variable geometry turbine; VGT; YOP; Collocation; Direct collocation; Optimal control; SI-engine; Engine control; Engine modelling;

   Abstract : The ever increasing demands on today's engine performance and emissions control is forcing the automotive industry to make use of innovative solutions. One of these is to apply the technology of VNT turbos on commercial petrol vehicles. READ MORE

3. 2. Implementation of a Model Predictive Controller in a Spark-Ignition Engine

   University essay from Linköpings universitet/Fordonssystem

   Author : Gustav Mann; Jakob Luedtke; [2021]
   Keywords : Model Predictive Control; SI engine; Variable Valve Timing; Throttle;

   Abstract : The propulsion of the spark-ignition engine has been investigated and developed during the past century to improve driveability, minimize fuel consumption and emissions, resulting in highly engineered and computerized powertrains. Well balanced engine maps containing coordinated set-points and model-based information sharing have solved the cross-coupling between different control loops. READ MORE

4. 3. 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

5. 4. Mechanical modelling of gaskets in exhaust after-treatment system of trucks

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Aneesh Ravikumar; [2020]
   Keywords : ;

   Abstract : With the world proceeding towards a clean and sustainable environment,the creation of technology and its implementation also needs to be sustain-able. The importance of combustion engine vehicles to meet more stringentemission standards puts a requirement on the industry to develop suitableafter-treatment systems to meet those standards. READ MORE

6. 5. Full Cycle Cylinder State Estimation in DI Engines with VVA

   University essay from Linköpings universitet/Fordonssystem

   Author : Linus Johansson; [2019]
   Keywords : VVT; Combustion engine; Thermodynamics; CRB;

   Abstract : Tougher legal demands on pollutions require a better developed understanding of the processes that take place in the cylinder. The thesis contributes with a cylinder model that uses the same set of equations for intake, compression,expansion/combustion and exhaust. READ MORE
