Vyhodnocení deformací vložky válce pomocí metod CAE

Abstract

The environmental restrictions, which become more and more demanding, force companies such as DAF Trucks to meticulously assess their engines through truly accurate 3D model, for purposes of optimizing as much as possible the performances of their vehicles. In that respect, DAF Trucks, during the examination of their engines, pays the greatest attention to the liners’ inner surface deformations, what might have consequences in terms of oil consumption in extreme cases. These defects mostly provoked by assembly forces, thermal loads and gas pressures may effectively induce a leakage of oil into the combustion chamber, what will, at the end, lead to an increase of hydrocarbon emission.
