  • Secondary airflow system for engine exhaust emission diagnostics
    Patent number: 7647765
    Abstract: In one example, a system for an engine having an intake system and an exhaust system is described. The system comprises: an airflow sensor coupled to the intake system; an air pump having at least an inlet side and an outlet side, said inlet side having a first coupling to the intake system downstream of said airflow sensor, said outlet side having a second coupling to the exhaust system; and a controller coupled to the engine, said controller, during operation, identifying whether degradation has occurred to at least one of said first and second couplings, and providing an indication of said identified degradation. Various other examples are also disclosed.
    Type: Grant
    Filed: October 20, 2006
    Date of Patent: January 19, 2010
    Assignee: Ford Global Technologies, LLC
    Inventors: Brent Sealy, Jeff Doering, Michael Cullen, David Wright, Paul Pietrzyk
