A system (10) for managing engine intake air temperature may comprise a first air flow control device (24) having an inlet coupled to an outlet of a turbocharger compressor (16) and a first outlet coupled to an inlet of a charge air cooler (22). A second outlet is coupled via a bypass conduit (26) to the air intake manifold (14). The first air flow control device (24) may selectively control air flow from the compressor outlet to the charge air cooler (22) and/or bypass conduit (26). The system may alternatively or additionally include a second air flow control device (30) having a first inlet receiving air external to the engine compartment, a second inlet receiving air from within the engine compartment and surrounding the engine and an outlet providing air flow to the engine. The second air flow control device (30) may selectively control airflow from the first and/or second inlets thereof to the engine. |
