Beschreibung
Zusammenfassung:	A system, method and apparatus for controlling a gas substitution characteristic in a dual fuel engine are provided. The gas substitution characteristic can be controlled based on measured characteristics directly or indirectly associated with operation of the dual fuel engine, including intake manifold air pressure (IMAP), load of the dual fuel engine, ambient air temperature, exhaust temperature, fan speed, and/or pressure of natural gas supplied to the dual fuel engine. Further, the gas substitution characteristic can be controlled by controlling intake manifold air temperature (IMAT) based on control of a cooling capacity of a cooling circuit.
