INJECTOR TIP CLEANING SYSTEMS AND METHODS |
摘要 |
A treatment control system comprises a monitoring module and an injection control module. The monitoring module monitors an exhaust temperature and an exhaust flow rate in an exhaust system of a vehicle. The injection control module controls injection of a dosing agent into the exhaust system for first and second regeneration events of a diesel particulate filter (DPF) and selectively injects a predetermined amount of the dosing agent into the exhaust system between the first and second regeneration events when the exhaust temperature is greater than a predetermined temperature and the exhaust flow rate is greater than a predetermined flow rate.
