The development of methodological techniques and an algorithm for diagnosing modern intake systems for internal combustion engines

Type Diagnosing and detecting malfunctions in internal combustion engines (ICE) is not an easy task due to their complex design. Timely high-quality ICE monitoring allows performance be maintained prevents breakdowns. Vibration acoustic analysis a powerful informative tool for faults even at early stage. This article considers method determining the main of valvetrain (VT) (tightness "valve-seat" interface, thermal gap valve drive, opening closing phases) by measuring analyzing vibroacoustic pulses caused operation individual engine elements. The maximum amplitude moment vibration impulses are used as signal parameters. For reference piston, top dead center (TDC) cylinder under study, pulse from impact piston on elastic tip placed chamber taken. technique makes it possible exclude external influences inaccuracies associated with change geometry
