  1. 1. 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
