1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER
2. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER
3. Optimal Knock Sensor Spatial Locations of In-line Combustion Engines : A Case Study of Scania Engines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In recent years, there has been a growing interest in utilizing knock sensors as a diagnostic tool for providing valuable insights into the combustion process. These sensors have demonstrated their potential to offer information regarding crucial parameters such as the start of combustion, heat release rate, misfire events, and valve events. LÄS MER
4. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER
