Abstract:
1. An engine method comprising: increasing intake air flow velocity through an intake air heat-exchanger by closing a valve arranged in an inlet tank of the heat-exchanger to direct air flow from through all of the heat-exchanger to through only a subset of the heat-exchanger and wherein increasing intake air flow velocity further comprises adjusting the valve from an open position in which intake air entering the heat-exchanger inlet tank flows through all cooling tubes of the heat-exchanger, to a closed position in which intake air entering the heat exchanger inlet tank flows through only a portion of the cooling tubes of the heat-exchanger, the portion being a subset of all of the tubes; and coordinately adjusting a position of one or more of an intake manifold throttle and a turbocharger wastegate in response to the increased intake air flow velocity to maintain engine torque.
