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.

Abstract: Systems and apparatuses include a controller including at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the controller to: determine a set of emission regulations based on a location of a vehicle; determine a target temperature of a catalyst of an aftertreatment system of the vehicle in response to the determined set of emission regulations; compare a current temperature of the catalyst to the determined target temperature; and in response to the current temperature of the catalyst being below the determined target temperature, provide a thermal management command to increase the catalyst temperature toward the determined target temperature.

Abstract: A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.

Abstract: The present disclosure provides an engine fueling system that includes multiple fueling valves such that the fuel transport delay can be reduced. The fueling system may also include an electrically driven compressor to improve engine properties during engine startup. For example, an engine fueling system comprising: a first compressor; an intake air throttle operably coupled to the first compressor and positioned downstream of the first compressor; a primary fuel path in communication with a fuel supply, wherein a first fuel from the fuel supply is injected into the primary fuel path upstream from the compressor; and a secondary fuel path in communication with the fuel supply, wherein a second fuel from the fuel supply is injected into the secondary fuel path downstream from the compressor.
