USE vibroacoustic SIGNALS FOR ASSESSMENT INTERNAL COMBUSTION ENGINE

E.I. Oksen, D.E. Oksen

Provides a methodology to identify defects in systems and mechanisms for internal combustion engines based on the assessment of the irregularity of vibration in the body of his work. The design of piezometric transducers for recording signals vibroacoustic emission propagating in the base parts of internal combustion engine. Developed equipment and software for mobile probing the complex. Established that the detection of defects in systems and mechanisms for internal combustion engines can be done by assessing the degree of irregularity of oscillations in the signals corps vibroacoustic emission. As a performance criterion is proposed to use the ICE correlation coefficient of experimental data with generalizing the exponential dependence.

Keywords: engine diagnostics, vibroacoustic emission, piezometric transducer, diagnosing complex.
