  • Processing system and method for calculating pressure decreases due to injection events in a high-pressure fuel system
    Patent number: 9567936
    Abstract: A system and method is provided to analyze an intermediate pressure signal portion between an end of an injection event signal portion and a start of a subsequent injection event signal portion. The analysis is simplified by identifying a plurality of single cycle windows and calculating a single value, such as a mean or a median, for each of the windows. An intermediate portion single value is determined by averaging the single values for each of the windows. The intermediate portion single value may then be used to identify pumping events or leakage errors that occur during the intermediate pressure signal portion that affect further analysis of the intermediate pressure signal portion.
    Type: Grant
