Thermo-Mechanical Investigation on an Automotive Engine Encapsulation System Made of Fiberglass Reinforced Polyamide PA6 GF30 Material

This paper deals with technological solutions of innovative engine encapsulation systems for automotive. The aim of this device is to insulate acoustically and thermally the engine from the environment, in order to keep its temperature higher for more hours after it has been switched off. If the engine is subsequently started within this interval, the higher temperature involving the lubricating oil will allow reducing its viscosity, resulting in a lower level of energy dissipation due to friction losses, a lower fuel consumption and, consequently, a lower CO2 emission level. In this paper, a finite element model is carried out in order to investigate on the thermo-mechanical behavior of the proposed engine encapsulation system.
