INTERNAL COMBUSTION ENGINE DIAGNOSING METHOD Russian patent published in 2000 - IPC

Abstract RU 2157983 C2

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to methods of diagnosing condition of mechanisms and machines, internal combustion engines in particular, by measuring clearances in different joints. Vibration pulses are separated on one of resonance frequencies of vibroacoustic channel corresponding to checked joint on shut-down engine by creating vibrations in checked joint using stand-by source (vibrator) at changing of vibration frequency till resonance effect. EFFECT: improved accuracy of diagnosing. 2 dwg
