Methods and systems for removing deposits in an aftertreatment system

A method for removing deposit in an aftertreatment system for an engine, the method comprising:

• 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.

A system comprising:

• a controller structured to:
• determine an amount of deposits accumulated in the aftertreatment system;
• determine combustion targets for the engine in response to determining the amount of deposits exceeds a deposit threshold;
• and
• modulate an air mass flow for the engine based on the determined combustion targets.
