Simulation of Heat Transfer with Variation of the Operating Conditions

Auszug

The future challenges in the area of the upcoming emission and consumption regulations for light duty engines can only be overcome with the help of an optimised warm-up phase. This requires an intelligent redistribution or use of the heat generated during the combustion process. All these measures, which are taken in order to optimise the warm-up phase or to improve the overall temperature distribution, are referred as thermal management. The aims of the thermal management are the optimisation of component temperatures, friction, emissions and fuel consumption. In the FVV project engine heat exchange, a thermal 1-D simulation model was created, which enables a preliminary calculation of the thermal behaviour by a diesel engine during the warm-up phase, thereby providing the groundwork for reducing consumption. Based on these results, at IMS the research project Engine Heat Exchange III was initiated to extend the model, perform thermal tests and examine a model transferability to other engines. …
