Therefore, the search and study of new diagnostic methods that allow quickly, as simple as possible, and reliably identifying faults is an urgent task. The justification for this statement can be carried out experimental studies of vibration of an internal combustion engine (ICE). As a result of these studies, ICE vibration was found to be acoustic in nature. It is proved that it is possible to use the directional microphone EM-8800 and the acoustic noise recorder of the 1st class Robotron 00023 as a sensitive element of the ICE valve mechanism diagnostics system. The exploratory partial survey runs on a full-scale Ford Keyphrases: ICE, acoustic, diagnostics, monitoring, vibration
