  3. 2. Optimal Knock Sensor Spatial Locations of In-line Combustion Engines : A Case Study of Scania Engines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hassan Hussein; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Forced response numerical investigation of a transonic compressor rotor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  5. 4. Statistical Analysis and Modelling of Engine Oil Degradation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Bastiampillai; [2023]
    Keywords : ;

    Abstract : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.

  6. 5. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE
