Abstract:
1. An engine thermal management system for split cooling and integrated exhaust manifold applications, the system comprising: a coolant pump; an engine block cooling jacket and an engine head cooling jacket, each configured to receive coolant directly from the coolant pump; an IEM cooling jacket configured to receive coolant directly from at least one of the coolant pump and the engine head cooling jacket; a first plurality of multi-port flow control valves configured to receive coolant from each of the engine block cooling jacket, the engine head cooling jacket, and the IEM cooling jacket, the first plurality of multi-port flow control valves including a first flow control valve and a second flow control valve, such that the first flow control valve receives coolant from the engine block cooling jacket and the second flow control valve receives coolant from each of the engine block cooling jacket, the engine head cooling jacket, and the IEM cooling jacket, wherein coolant flows through each one of the first plurality of multi-port flow control valves independently of each of the other ones of the first plurality of multi-port flow control valves; a heater core configured to receive coolant from at least one of the first plurality of multi-port flow control valves; a radiator configured to receive coolant from at least one of the first plurality of multi-port flow control valves; at least one control module configured to regulate the coolant pump and actuate the first plurality of multi-port flow control valves; and wherein the coolant pump is configured to receive coolant from each of the radiator, the heater core, and at least one of the first plurality of multi-port flow control valves.
