Abstract

Systems and methods are disclosed that relate to an SCR aftertreatment system and incentives/inducements for an operator/user to maintain the SCR aftertreatment in compliance with operating requirements and/or regulations. An engine is operationally coupled to at least one of a DEF tank and an SCR aftertreatment system. An inducement signal value is determined in response to a threshold value being obtained relating to at least one of the DEF tank level indication, a DEF quality indication, and an SCR aftertreatment system malfunction indication. The inducement signal value initiates at least one derate value of the engine to incentivize or induce the operator to have the aftertreatment system maintained and avoid or prevent out-of compliance operation of the SCR aftertreatment system.
