The heat transfer phenomena in a turbo-charged diesel engine is simulated by integration of several CAE-tools including CFD, FEA and 1D codes for cooling system and gas exchange simulation. By using in-house methodologies 3D data is exchanged between CFD and FEA. The modelling time and the required computing power are thereby minimized. Two loops of thermal simulations are performed. The predicted temperatures are in good agreement with the measured data. The precision cooling strategy used here is efficient and it results in equally cooled cylinders. The engine temperatures in the sensitive regions are kept below the critical limits.
