SYSTEM AND METHOD FOR REGENERATING A PARTICULATE FILTER |
| 摘要 |
Methods and systems are provided for determining soot stored in a particulate filter and regenerating the particulate filter. In one example, a method provides for operating oxygen sensors in a way that allows water in exhaust gases to be determined. The water in exhaust gases may be a basis for determining an amount of soot stored in a particulate filter. |

1. A method for regenerating a particulate filter, comprising:
estimating an amount of water stored within the particulate filter; estimating an amount of soot stored within the particulate filter from empirically determined soot amounts indexed via the amount of water stored within the particulate filter; and regenerating the particulate filter in response to the amount of soot stored within the particulate filter. |
