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.

Abstract: A natural gas system for an intake manifold of a dual fuel engine is provided. The natural gas system includes a heat exchanger configured to exchange heat with a first stream of natural gas passing therethrough. The natural gas system further includes a temperature regulating assembly positioned downstream of the heat exchanger with respect to the first stream of the natural gas. The temperature regulating assembly includes a conduit having an inlet and an outlet. The temperature regulating assembly also includes a supply line in selective fluid communication with the conduit. The temperature regulating assembly further includes a temperature sensing assembly provided within the conduit. Further, the introduction of the second stream is based on a temperature of the natural gas within the conduit.
