A Test Lab Cooling System Heat Transfer Model for Armored Vehicle Diesel Engine

A model based on the lumped parameter method is developed for the test lab cooling system of armored vehicle engine. Heat transfer and working properties of engine combustion chamber, radiator, cooling system, water pump and thermostat are included. It is the aid means for improving cooling system performance. An example simulation is implemented for 12V150 turbocharged diesel engine. The results show that this model can be used for studying heat performance of cooling system.
