Abstract
An engine thermal management system and method for a vehicle engine that allows for reduced coolant flow and energy consumption by the system, while avoiding excessive critical metal temperatures in the engine. The engine includes a coolant inlet in a head and a coolant outlet in a block. A variable speed pump pushes the coolant into the head inlet. A multi-port valve receives the coolant exiting the engine block and selectively routes it to various system components. The speed of the pump and the valve are electronically controlled by a control module, based upon various engine and vehicle operating conditions.
Claims7
A vehicle apparatus comprising:
- an engine having head, with a coolant inlet and head passages connected to the inlet, and a block, with a coolant outlet and block passages connected between the head passages and the outlet;
- a water pump having a pump outlet operatively engaging the coolant inlet and pump a coolant thereto, and a pump inlet;
- a multi-port valve having a valve inlet operatively engaging the coolant outlet of the block, a first valve outlet selectively engagable with the valve inlet, a second valve outlet selectively engagable with the valve inlet, a third valve outlet selectively engagable with the valve inlet, and a fourth valve outlet selectively engagable with the valve inlet;
- a radiator operatively engaging the first valve outlet and the pump inlet;
- a bypass operatively engaging the second valve outlet and the pump inlet;
- a heater core operatively engaging the third valve outlet and the pump inlet;
- a degas container operatively engaging the fourth valve outlet and the pump inlet;
- and
- a controller operatively engaging the valve to control the selective engagement of the valve inlet with the first valve outlet, the second valve outlet, the third valve outlet and the fourth valve outlet;
An engine thermal management system for an engine having head, with a coolant inlet and head passages connected to the Inlet, and a block, with a coolant outlet and block passages connected between the head passages and the outlet, the engine thermal management system comprising:
- a water pump having a pump outlet adapted to operatively engage the coolant inlet and pump a coolant thereto, and a pump inlet;
- a multi-port valve having a valve inlet adapted to operatively engage the coolant outlet of the block, a first valve outlet selectively engagable with the valve inlet, a second valve outlet selectively engagable with the valve inlet, and a third valve outlet selectively engagable with the valve inlet;
- a radiator operatively engaging the first valve outlet and the pump inlet;
- a bypass operatively engaging the second valve outlet and the pump inlet;
- a degas container operatively engaging the third valve outlet and the pump inlet;
- and
- a controller operatively engaging the valve to control the selective engagement of the valve Inlet with the first valve outlet and the second valve outlet.
