Virtual Product Development and Modern Diesel Engines

Virtual Product Development and Modern Diesel Engines

Paper in proceedings (conference paper)

The presentation deals with the virtual product development of the in-line six-cylinder diesel engine. The main components of the cranktrain have been modelled as flexible bodies using the finite element method (FEM) and then converted into a multi-body system (MBS). The sliding bearings of the cranktrain have been modelled using a database of reaction forces in the hydrodynamic oil film. Loading forces have been applied based on the values of combustion pressures measured in an engine cylinder. A viscous-type torsional damper and rubber damper has been designed to reduce the engine vibrations. Experimental verification of the computational model results has been performed by measuring the values on a testing engine unit using non-contact laser measuring technique.
