ELECTICALLY HEATED PARTICULATE FILTER INCOMPLETE REGENERATION IDENTIFICATION SYSTEM AND METHOD |
摘要 |
A system comprises a regeneration module and a diagnostic module. The regeneration module controls an electric heater to heat exhaust gas produced by an engine. The regeneration module determines when a regeneration cycle of a particulate matter (PM) filter begins by comparing a temperature of the exhaust gas input to the PM filter and a first temperature threshold. The diagnostic module determines a regeneration status by comparing a temperature of the exhaust gas output by the PM filter and a second temperature threshold during a predetermined period after the regeneration cycle begins.
