  • Diesel particulate filter control
    Patent number: 8572952
    Abstract: Methods and systems are provided for managing particulate emissions in an engine including a particulate filter and a CO2 sensor downstream of the filter. A CO2 sensor may be used to infer the presence of particulate matter in the exhaust, downstream of the filter. By sensing particulate matter in the post-filter exhaust, filter degradation may be identified.
    Type: Grant
    Filed: April 3, 2012
    Date of Patent: November 5, 2013
    Assignee: Ford Global Technologies, LLC
