Abstract (en)

A fuel injection system (5) for an engine (10) with a chamber (12) is disclosed. The fuel injection system (5) includes a plurality of pressure sensors (11) for detecting a plurality of pressure values within the chamber (12). The fuel injection system (5) also includes an ECU (20) that receives the plurality of pressure values detected by the plurality of pressure sensors (11). The ECU (20) generates a distribution of characteristic dispersion of a sensor simplex based on the plurality of pressure values detected by the plurality of pressure sensors (11). Also, the ECU (20) processes the distribution of characteristic dispersion to generate a distribution result that is within the distribution of characteristic dispersion. Moreover, the ECU (20) obtains a pressure result based on the distribution result.
