Abstract
A system, method, and apparatus for controlling intake manifold air temperature (IMAT) of a dual fuel engine are provided. A determination regarding whether IMAT is to be modified is performed, followed by modifying the IMAT by changing flow of coolant in a cooling circuit in fluid communication with a separate circuit aftercooler (SCAC) of a SCAC circuit from a first flow path to a second flow path when it is determined that the IMAT is to be modified. A portion of the first flow path overlaps a portion of the second flow path.
