1. 1. The mechanism behind internal injector deposits

   University essay from KTH/Kemiteknik

   Author : Jenny Blomberg; [2023]
   Keywords : Biodiesel; deposit formation; engine oil; calcium sulphate; internal diesel injector deposits; Biodiesel; beläggningsbildning; motorolja; kalciumsulfat; interna dieselinjektorbeläggningar;

   Abstract : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets  körbarhet. READ MORE

3. 2. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

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

   Author : Elias Aretorn; [2023]
   Keywords : CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

   Abstract : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. READ MORE

4. 3. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances

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

   Author : Johan Germundsson; [2023]
   Keywords : master thesis; cam phaser; simulation; 1D-simulation; GT-SUITE; GT-ISE; Gamma Technologies; oil aeration; oscillations; heavy-duty; engine; phaser; cam torque; stability; cam phaser system; Scania; Scalia CV;

   Abstract : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. 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. Use of a multi-parameter sensor for oil degradation monitoring

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Nicolas Gasnier; [2022]
   Keywords : ;

   Abstract : The continuous monitoring in real time of the degradation of lubricants is of great interest for many different industries to optimize the use of lubricating oil in combustion engines. Traditional oil quality diagnostic methods can measure accurately the different levels of oil degradation, but they cannot be implemented on engines to perform continuous oil quality diagnostics.
