1. A system, comprising:
an engine charge air cooler (CAC), including a plurality of regulatable and non-regulatable cooling tubes flowing charge air; and an air flow control arrangement within the CAC configured to selectively ensure that a flow rate of charge air, from a compressor, through each individual cooling tube of the regulatable cooling tubes is either essentially zero or above a predetermined minimum flow rate in accordance with predetermined operating conditions of an engine, where the air flow control arrangement includes a plurality of valves each configured to selectively provide access to or to restrict access to a respective one or more of the regulatable cooling tubes and where the CAC includes coolant passages flowing coolant over the plurality of regulatable and non-regulatable cooling tubes, the coolant including one or more of ambient air, water, or chemical coolant.
