摘要： An enhanced split cooling system for a turbocharger and an engine includes an oil cooler, a three-way valve assembly and a four-way valve assembly for controlling the flow of coolant, and radiators and subcoolers, for controlling coolant temperature. The valve assemblies are independently controllable to direct coolant through an oil cooler and a turbocharger intercooler either directly from the engine if the oil cooler and intercooler require heating or from the radiators and subcoolers if the oil cooler and intercooler require cooling. Depending upon the engine operating temperature, the valve assemblies can be configured to establish at least three different coolant processing modes.
