Abstract: Methods and systems of controlling a dual fuel engine with at least two banks of cylinders are provided. The method may include sensing at least one of temperatures of exhaust from the at least two banks and a pressure of an intake manifold of the at least two banks, and adjusting at least one of a gas flow, a charge flow, or an air flow to one of the at least two banks to balance one of exhaust temperatures of the at least two banks and intake manifold pressures of the at least two banks.

Abstract: Methods and systems of controlling operation of a dual fuel engine are provided, comprising determining a target exhaust temperature, sensing an actual exhaust temperature, determining an exhaust temperature deviation by comparing the actual exhaust temperature to the target exhaust temperature, comparing the exhaust temperature deviation to a threshold, adjusting at least one of an intake throttle, a wastegate, a compressor bypass valve, an exhaust throttle, a VGT and engine valve timing when the exhaust temperature deviation exceeds the threshold to control charge-flow to the engine, and continuing the adjusting until the exhaust temperature deviation is less than the threshold.
