Utility
System and method for measuring fuel injection during pump operation
10 Oct 23
A method is disclosed of controlling operation of a fuel injector in response to measuring a quantity of fuel injected by the fuel injector from a fuel accumulator to an engine cylinder during operation of a fuel pump that delivers fuel to the accumulator, comprising: determining an average pressure of the fuel accumulator during a first time period before a fuel injection event; predicting a mass of fuel delivered to the fuel accumulator during a pumping event (Qpump); determining an average pressure of the fuel accumulator during a second time period after the fuel injection event; estimating a leakage of fuel; computing the injected fuel quantity by adding the average pressure during the first time period to Qpump, and subtracting the average pressure during the second time period and the leakage; and using the computed injected, fuel quantity to control operation of the fuel injector.

Utility
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.
