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. 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

4. 3. Physically Based Modelling for Knock Prediction in SI Engines

   University essay from Linköpings universitet/Fordonssystem

   Author : Nils Thornberg; Jonas Eriksson Kraft; [2018]
   Keywords : knock; engine; si; si-engine; prediction; modelling; heat; release; knack;

   Abstract : The high demand for an increase in performance and at the same time loweringthe emissions is forcing the automotive industry to increase the efficiency of thevehicles. This demand lead to a problem called knock, which often is the limitingfactor when increasing the efficiency of the engine. READ MORE

5. 4. Effects and Models of Water Injection in an SI Engine

   University essay from Linköpings universitet/Fordonssystem

   Author : Joel Westling; Haris Subasic; [2018]
   Keywords : ;

   Abstract : Downsizing and turbocharging is a popular combination nowadays in cars inorder to decrease the fuel consumption. However, the boost pressure increasesthe risk of engine knock, limiting the engine in high-load operating points. Inthe current engines, fuel is used to cool the engine in these operating points,leading to a higher fuel consumption. READ MORE

6. 5. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Alejandro Simó Vesperinas; [2018]
   Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

   Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE
