A Dynamic Simulation Model for Cooling System of Vehicle Internal Combustion Engine

A dynamic heat transfer model based on the lumped parameter method was developed for cooling system of vehicle internal combustion engine.Engine combustion chamber heat transfer,radiator heat transfer,water pump heat transfer were included in the model.The heat coupling between the engine block and coolant,radiator and coolant,water pump and coolant were formulated.An example simulation was implemented for a single cylinder diesel engine.The results show that this model can be used for studying heat performance of cooling system.
