  • Methods of cleaning gas sensors
    Patent number: 10138794
    Abstract: Methods for cleaning gas sensors used in an exhaust gas system are provided. The exhaust gas system can include an exhaust gas stream supplied by an exhaust gas source through an exhaust gas conduit, and a gas sensor having a sampling end disposed within the exhaust gas conduit. The methods can include positioning at least one glow plug proximate the gas sensor; and activating the at least one glow plug such that exhaust gas deposits accumulated on the gas sensor sampling end are removed. The methods can optionally further comprise one or more of determining a glow plug activation interval and determining a glow plug activation duration. Systems for performing the disclosed methods are also provided.
