METHOD AND SYSTEM FOR CONTROLLING AN ENGINE DURING DIESEL PARTICULATE FILTER REGENERATION AT IDLE CONDITIONS |
摘要 |
A method and control system for controlling an engine during diesel particulate filter regeneration includes a diesel particulate filter (DPF) regeneration request module that generates a DPF regeneration request signal and an idle condition module that generates an idle condition signal when the engine is at an idle condition. A DPF regeneration control module initiates a timer in response to the DPF regeneration request signal and the idle condition signal. The DPF regeneration control module controls the engine oxygen level to a second level less than a first level corresponding to a non-idle speed level, and after a time period, controls the engine to generate oxygen at a third level greater than the second level.
