Abstract
An integrated transient engine simulation methodology has been developed to allow the calculation of a thermal shock as it propagates in time through the engine structure. It links, in a fully consistent way, a very comprehensive thermodynamic model of in-cylinder processes, including a detailed gas-phase heat transfer representation, with a turbocharger/air flow/plenum model and a finite element model of the structure. The methodology tracks the turbocharger boost increase and the cycle-by-cycle build-up of in-cylinder heat transfer during engine load and speed changes, producing a transient thermal response in the structure, until new steady-state is reached. The presented results highlight the calculated transient engine performance response and the thermal and stress response of various metal and ceramic components during sudden speed and load changes in heavy duty diesel engines.
