  • Methods and systems for monitoring loading of an air filter
    Patent number: 9983114
    Abstract: Methods and systems for estimating the loading of an air filter are disclosed herein. The method includes receiving upstream mass air flow data indicative of a mass air flow on an upstream side of an air filter (i.e., the “dirty side of the filter”), receiving downstream air pressure data indicative of an air pressure on a downstream side of the air filter (i.e., the “clean side of the filter”), and receiving downstream temperature data indicative of a temperature on the downstream side of the air filter. The method also includes determining a differential pressure (?P) across the air filter indicative of a loading of the air filter based on the upstream mass air flow data, the downstream air pressure data, and the downstream temperature data.
