Abstract: A method of controlling a fuel injector comprises measuring a pressure in a cylinder of an engine with a pressure sensor and determining at least one of a crank angle and a crank speed with a crank sensor. The method also comprises calculating a net indicated mean effective pressure of the cylinder from the measured value of the pressure sensor and the determined value of the crank sensor. Also, the method comprises adjusting a fueling parameter of a fuel injector for the cylinder in response to the difference between the calculated net indicated mean effective pressure and a reference mean effective pressure indicates a change in power of the engine. Alternatively, the method may adjust the fueling parameter based on a power feedback signal for the engine.

Abstract: Systems, methods, and apparatuses are provided for increasing exhaust gas temperature. A system includes a valve and a controller coupled to the valve. The controller is structured to determine that a plurality of cylinders of an engine are active; compare an exhaust aftertreatment temperature to an exhaust aftertreatment temperature setpoint; and in response to the comparison, adjust an effective flow area for exhaust gas from the plurality of cylinders of the engine to increase an exhaust gas temperature.

Abstract: Systems, methods, and apparatuses are provided for increasing exhaust gas temperature. A system includes a valve and a controller coupled to the valve. The controller is structured to determine that an exhaust manifold pressure does not meet an exhaust manifold pressure setpoint and in response, cause an adjustment of an effective flow area of exhaust gas from an engine. The adjustment of the effective flow area is structured to increase an exhaust gas temperature.

Abstract: A method for increasing the exhaust temperature of an exhaust system. The method includes receiving an inlet temperature of a selective catalytic reduction system; determining whether the inlet temperature meets a temperature setpoint; adjusting an exhaust manifold pressure setpoint based on the determination of the inlet temperature; determining whether the exhaust manifold pressure of at least one of first or second bank meet the exhaust manifold pressure setpoint; and causing an adjustment of an effective flow area of at least one of the first bank or second bank based on the exhaust manifold pressure, the adjustment of the effective flow area structured to increase exhaust temperature during light load operation.
