NUMERICAL MODELING OF THE CYLINDER-HEAD GASKET’S DISPLACEMENT FIELD, BASED ON EXPERIMENTAL DATA

Abstract

Durability of the internal combustion engines depends also on the behavior of the superior engine area, and especially that of the cylinder-head gasket. The cylinder-head gasket represents the elastic element that closes the engine chamber. Malfunctioning and noxious pollution on can observe, if this role is not entirely satisfied. This will lead to a non-competitive engine. The authors of this paper preoccupied themselves with the analysis of geometric factors of the superior area zone, so that a competitive engine will obtain. Taking into account the accuracy analysis of the elastic properties of the cylinder-head gasket [4], a mechanism of the deformation of cylinder-head gasket during pre-tensioning (of cylinder-head gasket mounting) and during fuel burning in the burning chamber was proposed. Based on these presumptions, the authors performed a FEM analysis of the cylinder-head gasket’s displacements field.
