ABSTRACT
The paper presents a new methodology for testing common rail fuel injectors, which extends the standard diagnostic procedure to include the analysis of the resultant fields of dosed fuel. The calculations were made on the basis of Gaussian formulas, also known as the shoelace formula. Their implementation in the digital environment was convenient from the practical side, as it eliminated the need to modify the test bench software. Thanks to the easy modification, the presented algorithms can be used in testing fuel injectors of other types or generations, for which clear assessment and verification of the technical condition is sometimes difficult. It is not required for this to increase the number of measuring points of the active experiment, which is one of the greatest advantages of the proposed solution.
