1. 1. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Johan Humla; Samuel Friman; [2023]
   Keywords : ;

   Abstract : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. READ MORE

3. 2. Compressor Surge: Simulation, Modeling and Analysis

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Robin Massiquet; [2022]
   Keywords : Turbo compressor; Surge; Simulation; Modelling;

   Abstract : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. READ MORE

4. 3. Modelling of high-pressure fuel system for controller development

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Eric Pettersson; [2019]
   Keywords : Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

   Abstract : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.

5. 4. Simulation and validation of in-cylinder combustion for a heavy-duty Otto gas engine using 3D-CFD technique

   University essay from KTH/Förbränningsmotorteknik

   Author : Jacob Arimboor Chinnan; [2018]
   Keywords : CFD; AVL FIRE; Otto Gas Engine; Combustion Modelling; ECFM Model; Flame Tracking Particle Model; Flame Tracking Model; G-Equation Model; Ignition Models.; CFD; AVL FIRE; Otto Gasmotor; Förbränningsmodellering; ECFM-modell; Flamspårningspartikelmodell; Flamspårningsmodell; G-ekvationsmodell; Tändningsmodeller;

   Abstract : 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. READ MORE

6. 5. Comparative Study of Different Organic Rankine Cycle Models: Simulations and Thermo-Economic Analysis for a Gas Engine Waste Heat Recovery Application

   University essay from KTH/Kraft- och värmeteknologi

   Author : Tihomir Rusev; [2015]
   Keywords : ORC; Waste Heat Recovery; Aspen Plus; Cascaded Cycle; Thermo-Economic; ORC Simulations; ORC Models; ORC Model Comparisons; Gas Engine Waste Heat Recovery; Hot Exhaust Gases; Multiple Waste Heat Sources; ORC Waste Heat Power Generation; Heat and Power; Combined Cycle; Siloxane;

   Abstract : Increasing the efficiency of conventional power plants is a crucial aspect in the quest of reducing the energy consumption of the world and to having sustainable energy systems in the future. Thus, within the scope of this thesis the possible efficiency improvements for the Wärtsilä 18V50DF model gas engine based combine power generation options are investigated by recovering waste heat of the engine via Organic Rankine cycle (ORC).
