Detection of delta pressure sensor icing
10 Oct 23
An engine system includes a delta pressure sensor configured to sense a pressure difference across an engine exhaust handling component and an electronic control system configured to determine a cold sensor condition permitting icing of the delta pressure sensor, determine a sensed pressure deviation condition indicative of deviation of the pressure difference sensed by the delta pressure sensor from a deviation limit, dynamically model a sensor heat transfer condition indicative of heating or cooling of the delta pressure sensor, determine that the sensor heat transfer condition is indicative of insufficient heating of the delta pressure sensor to mitigate icing of the delta pressure sensor, and determine an icing condition of the delta pressure sensor.
