  1. 1. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

    Abstract : Noise pollution is a growing concern due to its harmfulness to human health. Heavy vehicles powered by internal combustion engines stands for a major part of the environmental noise, why noise reduction is an increasing priority in enginve development. READ MORE

  4. 3. Cavitation in Engine Cooling Fluid due to Piston-Cylinder Assembly Forces

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Anthony Deku; Subramanya Kompella; [2006]
    Keywords : Cavitation; Cooling fluid; Internal Combustion Diesel Engine; Ansys; Vibrations; Acoustics; Fluid-Structure Interaction;

    Abstract : The problem of possible pitting and cavitation in internal combustion engines is receiving considerable attention. Both theoretical and simulation simulation studies are carried out in order to understand the noise and vibration sources, using a force equation. For this work, the main aim is to actually study these vibrations and try to model it. READ MORE
