Abstract: A vehicle having an air intake system includes a charge air cooler, an intake duct, an outlet duct, and a bypass duct. The charge air cooler has a charge air inlet that is disposed at a first end of a charge air cooler core and a charge air outlet that is disposed at a second end of the charge air cooler core. The intake duct extends between an outlet of a turbocharger and the charge air inlet. The outlet duct extends between the charge air outlet and a throttle body having a throttle body valve that is operatively connected to an engine intake manifold. The bypass duct has a bypass valve. The bypass duct is connected to the charge air inlet and the charge air outlet. The bypass valve is configured to selectively facilitate bypass flow through the bypass duct.

Abstract: A coolant control system of a vehicle includes a pump control module and a coolant valve control module. The pump control module selectively activates a coolant pump. The coolant pump pumps coolant into coolant channels formed in an integrated exhaust manifold (IEM) of an engine. The coolant valve control module selectively actuates a coolant valve that controls coolant flow from the coolant channels formed in the IEM to a transmission heat exchanger based on a first temperature of a transmission and a second temperature of coolant within the integrated exhaust manifold of the engine.

Abstract: A thermostat for use in the coolant passage of an internal combustion engine includes a valve seat and a valve plate with an elastomeric seal engaged with the valve seat in a closed condition and movable away from the valve seat in an open condition. The valve plate has a wavy surface disposed below the elastomeric seal that engages the valve seat, wherein the wavy surface is nonplanar with surface variations of at least 300 microns. The wavy valve plate creates a situation where the thermostat operates with two effective modes, a low flow regime for low load conditions where the valve is only traveling between 0 and approximately 1 mm while the wavy plate allows a low coolant flow and a high flow regime (valve fully open) for high engine load situations that require maximum cooling.
