Embodiment Construction

[0022] Referring to the drawings, wherein like reference numerals represent like parts throughout the several views, figure 1 A vehicle 10 is shown having a powertrain 12 and a powertrain cooling system 14 operable in multiple coolant flow modes to improve vehicle efficiency as described herein. The powertrain 12 includes an engine 16 having an engine block 18 and a cylinder head 20 . The powertrain 12 also includes a transmission 22 that is operatively connected to and driven by the engine 16 to propel the vehicle 10 . Additionally, the vehicle 10 includes a passenger compartment heater 23 operable to provide heat to the passenger compartment in thermal communication with the heater 23 . The passenger compartment is not shown, but is known in the art as the space surrounded by the body of the vehicle in which passengers in the vehicle 10 sit. The passenger compartment is adjacent to a heater 23 which may be located in the engine compartment under the hood of the vehicle 10 ...

Abstract

The present invention relates to a power transmission system cooling system, which includes a coolant pump and the coolant passage. The first three-way valve connected to the coolant pump outlet operatively, and having first, second and third positions, to at least partially create the coolant flow through the coolant flow channels in different modes. When the three-way valve in a first position, the flow of coolant from the coolant pump is blocked and can not reach the cylinder head and the engine block. When the three-way valve in the second position, the second coolant flow mode, the coolant flow from the coolant pump is supplied to the cylinder head and the engine is blocked and can not reach the cylinder. When the three-way valve in the third position, the coolant flow in the third mode, the coolant flows is from the coolant pump to the engine block and from the cylinder head to the engine block.

Description

technical field [0001] The present invention generally includes powertrain cooling systems and methods for cooling a powertrain. Background technique [0002] Rapid warming of engine coolant, engine oil, and transmission oil after a cold start improves vehicle fuel economy. A cold start is when the vehicle is not being driven and the engine and transmission are relatively cold. Engine warm-up is challenging for diesel and hybrid applications because less fuel is burned. Contents of the invention [0003] The power train cooling system is configured to allow rapid warming of power train components and fluids, improving fuel economy by reducing frictional losses. The power train cooling system includes a coolant pump and multiple coolant passages. A first three-position valve is operatively connected to the coolant pump outlet and has first, second and third positions to at least partially establish different coolant flow patterns through the coolant flow passage. Coolan...
