ABSTRACT:
A system and method for maintaining an airflow path to a turbocharger system on a locomotive operating at high altitude and in a low ambient temperature environment, is provided and includes generating an ambient air stream flow into the turbocharger system to create a compressed air stream flow having a compressed air stream temperature, processing the compressed air stream to create an intercooler air stream having an intercooler air stream temperature, directing at least a portion of at least one of the compressed air stream and the intercooler air stream toward a controllable re-circulation device, operating the controllable re-circulation device to combine the at least a portion of at least one of the compressed air stream and the intercooler air stream with at least one of the compressed air stream flow and the ambient air stream.
