Benefit of Coolant Control Module for Thermal Management on SUV 2017-01-0152
Advanced technology of thermal management is an effective method to reduce fuel consumption. There are several different technologies for coolant control, for example, electric water pump, split cooling and coolant control module. Through 1D thermal management simulation, coolant control module was chose for the test due to the best benefit for fuel consumption under NEDC cycle. 1D thermal management simulation model includes vehicle, cooling system, lubrication system and detailed engine model with all friction components.
Coolant control module is designed to fix on 2.0L turbocharger GDI gasoline and to control 5 coolant ways, including radiator, by-pass, engine oil cooler, cabin heater and transmission oil cooler. The prototype is designed and made. The function and strategy is verified on designed test-bed. The vehicle with coolant control module is running under NEDC cycle. The results show the coolant temperature rise time decrease and the benefit of fuel consumption reach 1.8%. After the test, coolant control module is confirmed applying on next generation 2.0L turbocharger GDI gasoline.
