A vehicle operates under various ambient conditions and various operating parameters. To compensate for the ambient condition and the operating parameters an engine, an intake air temperature is controlled. One of an ambient air flow restriction system or an intake air flow restriction system is used to vary the flow of a recipient ambient air flow through an air to air or the flow of a donor intake air flow through the aftercooler respectively. A plurality of louvers are operatively moved between a closed position and an open position with the ambient air flow restriction system. And, a flapper valve is operatively moved between a closed position and an open position with the intake air flow restriction system. A controller interprets a respective signal from a plurality of sensors to define the position of the plurality of louvers or to define the position of the flapper valve.

1. A system for controlling the temperature of an intake air flow used to support combustion in an engine, said system comprising:an exhaust gas having a portion thereof circulated to said intake air flow; an air to air aftercooler having said intake air flow being a donor fluid; an ambient air flow acting as a recipient fluid for cooling said intake air flow and passing through said aftercooler; a plurality of sensors being operatively-positioned in said ambient air flow and said intake air flow; a controller being operatively connected to said plurality of sensors; one of an ambient air flow restriction system having a restriction device and an intake air flow restriction system having a restriction device; and said controller defining a position of said restriction device between an open position and a closed position.
