Abstract
An enhanced split cooling system and method for a turbocharged internal combustion engine including a liquid cooled turbocharger and an engine liquid coolant jacket , the system comprising a coolant pump for pumping coolant from a coolant storage tank in heat exchange relationship with the engine jacket and turbocharger ; an oil cooler having coolant input and output lines; a valve assembly including a multi-port rotary valve actuated by a single actuator; a first coolant output line connected for conveying coolant from the engine to the valve assembly ; a radiator connected via a second coolant line for receiving coolant from the valve assembly and having a coolant outflow line to return coolant to the coolant tank ; an intercooler operatively associated with the turbocharger for passing the coolant in hear exchange relationship with compressed air in the turbocharger ; a lube oil subcooler coupled by a third coolant flow line to receive coolant from the radiator and having a coolant outflow line selectively couplable through the valve assembly to the oil cooler and the coolant tank ; an intercooler subcooler coupled by a fourth coolant flow line to receive coolant from the oil subcooler and having a coolant outflow line selectively couplable through the valve assembly to the coolant tank and the intercooler ; and the valve assembly being independently operable for selectively directing coolant flow through the radiator and subcoolers and the oil cooler and intercooler as a function of engine operating temperature.
