A method and system for monitoring a particulate filter |
| 摘要 |
A low cost particulate filter pressure monitoring system and method are presented. The differential pressure across the filter is estimated based on an atmospheric pressure, a measured absolute exhaust gas pressure upstream of the first emission control device coupled to the engine and an estimated pressure drop across all other emission control devices. |
