Exhaust treatment system diagnostic via ammonium nitrite decomposition |
摘要 |
A method of monitoring operation of an exhaust treatment system of a diesel engine includes injecting a dosing agent into an exhaust and monitoring the operating conditions of an engine during normal driving conditions. A control module monitors inlet and outlet temperatures of a catalyst and compares the inlet temperature to the outlet temperature. The control module further evaluates the exhaust treatment system based on the inlet temperature, the outlet temperature and a predetermined temperature threshold. |
