Abstract: A method includes: determining that at least one cylinder of a first cylinder bank of an engine is active; determining that at least one cylinder of a second cylinder bank of the engine is inactive; receiving an inlet temperature of a selective catalytic reduction system; comparing the inlet temperature to a temperature setpoint; and adjusting at least one of a first exhaust manifold pressure setpoint for the first cylinder bank or a second exhaust manifold pressure setpoint for the second cylinder bank based on the comparison.
