A controller for removing deposits in a vehicle is disclosed. The controller includes at least one processor and a memory storing instructions therein that, when executed by the at least one processor, cause the at least one processor to: determine an amount of deposits accumulated in the vehicle based on an amount of time; determine a combustion target for the vehicle in response to determining that the amount of deposits exceeds a deposit threshold; and modulate a fluid flow of the vehicle based on the determined combustion target.

Methods and systems for removing deposits in an aftertreatment system

Systems and methods for removing deposit in an aftertreatment system for an engine are disclosed herein. The method comprises determining an amount of deposits accumulated in the aftertreatment system, determining combustion targets for the engine in response to determining the amount of deposits exceeds a deposit threshold, and modulating an air mass flow for the engine based on the determined combustion targets. The air mass flow can be modulated by changing the position of the wastegate or the geometry of the variable geometry turbine (VGT).
