Abstract
An algorithm or diagnostic for detecting and alarming unintended exothermic conditions in exhaust after treatment components selectively detects alarming temperature variations in exhaust after treatment components when caused by internal unintended exothermal events, rather than transient conditions that are externally driven. Not only are the output temperature and the delta temperature (T_out−T_in) across the component monitored in each after-treatment device, but also the input temperature is deeply analyzed through its recent history data in order to determine if any input variations caused the output changes.
