Abstract: Managing firing fraction transitions of a variable displacement internal combustion engines by (a) avoiding transport delays in an Exhaust Gas Recirculation (EGR) feed by starting movement of an EGR valve position after a decision to transition to a new firing fraction has been made, but prior to the start of the transition and (b) adjusting the EGR valve as needed during the transition so as to maintain an EGR fraction within a predetermined range during the transition. By performing both (a) and (b), spikes of nitrous oxide (NOx) and/or hydrocarbon emissions are reduced or altogether eliminated during the transition.

Abstract: At least some embodiments of the present disclosure are directed to systems and methods for controlling a cylinder deactivation (CDA) operation for an electrified powertrain, the electrified powertrain comprising an engine and an additional power source, the engine having a plurality of cylinders. The method includes the step of operating the electrified powertrain in a CDA mode and deactivating one or more selected cylinders of the plurality of cylinders; receiving measurement data indicative of operating conditions of the electrified powertrain; analyzing the measurement data to determine whether a predetermined operating condition is met; and adjusting the CDA operation by adjusting the duration of the CDA operation or changing a number of deactivated cylinders.

Abstract: A system includes a valve actuation system, a pre-lubrication pump coupled to a lubrication circuit and configured to provide oil to the valve actuation system, a catalyst for receiving and treating exhaust gasses, and a controller. The controller is configured to identify an engine start request and determine whether the catalyst temperature is below a first threshold value. In response to determining that the catalyst temperature is below the first threshold value, the controller actuates the pre-lubrication pump to direct lubricant to the valve actuation system, controls the valve actuation system to deactivate at least one cylinder of an engine, and, subsequent to deactivating the at least one cylinder of the engine, cranks the engine.

Abstract: An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler (“CAC”), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.

Abstract: Apparatuses, methods, and systems for igniting fuel for an internal combustion engine, an ignition system include a first ignition device associated with a pre-combustion chamber of a cylinder and a second ignition device associated with a main combustion chamber of the cylinder. An engine control unit is operably connected to both the engine and the ignition system to ignite fuel for the cylinder with the first ignition device independently of igniting fuel with the second ignition device. The engine control unit determines an occurrence of a combustion condition and in response thereto (i) ignites fuel for combustion with both the first and the second ignition devices or (ii) ignites fuel for combustion only with the second ignition device. The engine control unit determines a second combustion condition and in response thereto ignites fuel only with the first ignition device.

Abstract: The present disclosure relates to dual fuel internal combustion engines with multiple cylinder banks and/or cylinder subsets, and exhaust aftertreatment systems associated therewith. Systems and methods are disclosed that relate to engine operations involving fuelling control for fuel cutout of one or more of the cylinder banks and/or cylinder subsets in response to a fuel cutout event to increase gaseous fuel substitution on the other cylinder banks and/or cylinder subsets to satisfy the torque request and thermal management conditions of the aftertreatment system.

Abstract: A method of calibrating a control system based on a parametric value of a component. The method includes receiving a current from a component of the control system. The component is communicatively coupled to a controller and has a parametric resistor with a parametric resistance value correlating to a parametric value associated with the component. The method further includes determining the resistance value of the parametric resistor by measuring a parametric voltage rating from the current. The method further includes mapping the resistance value to the parametric value associated with the component. The method further includes generating a calibration data set. The calibration data set is based on calibrating the control system to calibrate for the parametric value. The method further includes transmitting a signal to the component. The signal is based on the calibration data set and is configured to calibrate operation of the component.
