The Enhancement and Validation of a Vehicle Engine Cooling System Simulation for a Heavy Duty Diesel Truck 880601
The Vehicle Engine Cooling System Simulation (VECSS) developed at Michigan Technological University in 1982 was enhanced to the extent that it can be used as a cooling system design tool for a heavy duty diesel truck. The enhancements are described in the present paper, while the use of the VECSS as a cooling system design tool is presented in the companion paper, “The Use of the Vehicle Engine Cooling System Simulation as a Cooling System Design Tool.”
The enhanced VECSS was validated by comparing predicted temperature results to data collected by the Cummin's Engine Company during Air-to-Boil (ATB) tests, and during an “over-the-road” dynamic run of a heavy duty diesel truck. The enhanced model provided results which compared very favorably to both, the steady state ATB data and the dynamic “over-the-road” data.
