MODEL-BASED SYSTEM AND METHOD FOR MITIGATING DIESEL EMISSION FLUID DEPOSITS

摘要

A system and method for mitigating deposit of diesel emission fluid (DEF) decomposition products on interior surfaces of an internal combustion engine exhaust system (14). A processor in a controller (34) contains a model-based control algorithm (50A; 50B) for controlling DEF injection by a DEF injector (24) to mitigate deposit formation.
