The suitability of the coherence function for marine engine injection pump diagnostics is described. The function was used for the examination of recorded acoustic emission clastic wave signals. Characteristic frequencies from a specific fault symptom were identified. It was proved that, with known multipliers defined for each normal coordinate, the interpretation of observation resulis allows to find unknown functions of fault symptoms. In this way, we can solve a problem of identification of a mathematical model sensitive to changes in a fault parameter.
