Abstract: Systems, apparatuses, and methods for monitoring a catalyst health parameter are provided. A system includes one or more processing circuits having one or more memory devices coupled to one or more processors. The one or more memory devices store instructions that, when executed by the one or more processors, cause the one or more processors to: receive information indicative of at least one of a temperature of exhaust gas entering the aftertreatment system, a time at idle, or a mass flow of exhaust gas; determine a catalyst health management criteria based on the information; determine a catalyst health indicator based on the catalyst health management criteria being met; compare the determined catalyst health indicator to a predetermined health threshold criteria; and provide a notification based on the determined catalyst health indicator being less than the predetermined health threshold criteria.

Abstract: Systems and apparatuses include a circuit structured to receive information indicative of a catalyst health, determine a catalyst health management criteria has been met based on the information, determine a catalyst loading based on the information and the catalyst health management criteria being met, and compare the determined catalyst loading to a predetermined loading limit. A notification circuit is coupled to the circuit and structured to provide a notification when the determined catalyst load exceeds the predetermined loading limit.

Abstract: Systems and methods for controlling fuelling of dual fuel internal combustion engines are disclosed. The control techniques maximize the substitution rate of gaseous fuel for the liquid fuel by determining a target fuelling amount for the liquid fuel and then regulating an actual fuelling amount of the liquid fuel in response to engine speed and power variations and by modulating the flow rate of the gaseous fuel to the engine.

Abstract: An apparatus for providing electrical power for a hybrid vehicle includes an integrated starter-generator and an inverter connected to an electrical energy storage device such as a capacitor and a battery by first and second switches respectively. A control turns the switches on and off in accordance with selected modes of operation to provide power from the capacitor to the integrated starter-generator and the battery and to provide power from the integrated starter-generator to the capacitor and the battery.
