Abstract
A thermal management system and method for split cooling and integrated exhaust manifold applications in an automotive engine is provided. The thermal management system includes a cooling circuit that directs coolant through a plurality of components to warm the engine and passenger compartment efficiently, as well as remove excess heat from the engine and promote a constant operating temperature during vehicle operation. The cooling circuit directs liquid coolant, propelled by a coolant pump, through at least one of an engine block cooling jacket, an engine head cooling jacket, and an integrated exhaust manifold (IEM) cooling jacket, along a variety of cooling paths. The cooling circuit also incorporates a plurality of flow control valves to selectively distribute flow of the liquid coolant between a radiator, an engine heater core, and a return path to the coolant pump.
