1. 1. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

   University essay from Linköpings universitet/Fordonssystem

   Author : Björn Kleman; Henrik Lindgren; [2021]
   Keywords : model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

   Abstract : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. READ MORE

3. 2. Automatic detection of the fuel composition in a Diesel Engine : Identifying fuel composition in the fuel system of a combustion engine and optimising for computational complexity

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Andree Hultgren; [2021]
   Keywords : Fuel Detection; Machine Learning; Feature Selection; Computational Complexity; Bränsledetektering; Maskininlärning; Paremeterval; Beräkningskomplexitet;

   Abstract : The transportation industry is responsible for 26% of all emission of greenhouse gases in the European Union. Many steps are being taken to minimise greenhouse gas emissions. The most effective way to reduce the emission of greenhouse gases is by transitioning to biofuels. READ MORE

4. 3. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

   University essay from Linköpings universitet/Fordonssystem

   Author : Jonatan Gustafsson; [2021]
   Keywords : MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

   Abstract : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. READ MORE

5. 4. Identifying risks of AdBlue spray on stainless steel surfaces

   University essay from KTH/Kemiteknik

   Author : Evelina Tvinne Flyg; [2021]
   Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

   Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

6. 5. 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
