Abstract
The paper deals with aspects regarding the match between main components of the diesel engine cooling system ( water pump, ventilator and radiator ) in order to provide efficient engine heat release and energy saving. For a heavy duty 797-05 diesel engine manufactured at ROMAN Truck factory there were performed an investigation of the heat exchange based on real measurements on test bench taking into account individual characteristics of cooling parts. The purpose of the investigation is to compare heat release potential of the engine in several versions of selection radiators and fans. The paper also identifies the steps in the thermodynamical match of the cooling system parts in order to generate a evaluation methodology of engine thermal load.
Keywords: diesel engine, heat release, cooling systems, radiators, axial fans
