Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, each of a first valve positioned in an exhaust gas recirculation (EGR) passage, the EGR passage coupled between the intake passage and the first exhaust manifold coupled to a first set of cylinder exhaust valves, and a second valve positioned in a flow passage coupled between the first exhaust manifold and the exhaust passage may be adjusted based on a measured pressure in the first exhaust manifold.

Abstract: Systems, devices, methods and programs for reducing emissions from engines are provided. For example, one system for reducing emissions from engines comprises a heating controller coupled to an energy storage device (ESD). The heating controller is configured to control a heating element to heat one or more components of an after-treatment system using energy from the ESD under a first condition and to control the heating element to stop heating the one or more components of the after-treatment system when a second condition is satisfied. Additionally, another system for reducing emissions from engines comprises a controller detecting a decrease in a demanded torque from an engine and an ISG. The controller is then configured to operate a clutch to disengage the engine from the ISG, if after removing fuel from the engine, the sensed speed of the engine is above a threshold.

Abstract: A catalyst control system includes a stop and start module that, during a period that the vehicle is ON between (i) a first time when the vehicle is turned ON and (i) a second time when the vehicle is next turned OFF, selectively shuts down and starts a spark ignition engine of the vehicle. A catalyst light off (CLO) control module initiates a first CLO event for a first engine startup during the period and, when a temperature of a catalyst that receives exhaust output by the engine is less than a predetermined temperature, selectively initiates a second CLO event for a second engine startup during the period. A fuel control module richens fueling of the engine during the first and second CLO events of the period. A spark control module retards spark timing of the engine during the first and second CLO events of the period.

Abstract: In a hybrid vehicle that includes an engine having a particulate matter removing filter configured to remove particulate matters in an exhaust system, when an increase in temperature of the particulate matter removing filter is requested in order to regenerate the particulate matter removing filter, dither control is executed to execute control such that an air-fuel ratio of the engine is repeated between a rich state and a lean state. Then, when the dither control is executed, control is executed such that the engine is operated at an operation point where the increase in temperature of the particulate matter removing filter is promoted among operation points where power output from the engine is retainable.

Abstract: A method for controlling an exhaust gas treatment system is provided. The exhaust gas treatment system includes an exhaust gas stream supplied by an exhaust gas source to a selective catalytic reduction device, and a reductant supply source utilizing a volumetric pump. The exhaust gas source can include an internal combustion engine (ICE), such as a gasoline or diesel ICE. The method for controlling an exhaust gas treatment system includes commanding a reductant dosing quantity, determining a volumetric pump energizing time, determining an energizing time correction, and energizing the pump. The volumetric pump can comprise pump logic, and the volumetric pump energizing time can be determined by the pump logic. The energizing time correction can be determined using a calibration table. The calibration table can prescribe an energizing time correction based on a current pump pressure and the commanded dosing quantity.

Abstract: A 3-phase driven resistor load bank, electrically connected to an engine-generator-set is controlled to maintain a minimum generator load by turning ON and OFF load-bank heaters for optimal operation of the engine. An operator selects KW power output that best meets electrical load conditions and the load bank converts surplus electrical energy to heat, then cooled by the exhaust gas. The exhaust-gas-cooled resistive heater load bank, mounted in gas flow path, provides a dummy load to the gen-set which allows gen-set to operate at operator defined load level to enhance engine performance and reduce maintenance costs. The gas flow cools the inline resistive heater elements. The 3-phase AC power to the resistor load bank is only switched ON/OFF at zero-crossing points to eliminate electrical noise.

Abstract: A system for apportioning reductant dosing amounts in multi-doser architectures includes an engine, an aftertreatment system in fluid communication with the engine, and a controller. The aftertreatment system includes a first doser configured to dose reductant into a first decomposition reaction member and a second doser configured to dose reductant into a second decomposition reaction member. The controller receives engine operating conditions and determines a total reductant amount based on the engine operating conditions. The controller also apportions the total reductant amount into a first apportioned reductant amount based on a first maximum reductant dosing amount for the first doser and a second apportioned reductant amount based on a second maximum reductant dosing amount for the second doser. The controller outputs a first apportioned reductant dosing command to the first doser and a second apportioned reductant dosing command to the second doser.
