This article provides an analysis of the technical operation of the elements of turbocharging systems of modem marine high-speed engines based on periodically obtained thermal parameters in operation using standard control units of the company "Caterpillar". Currently, there are no regulatory documents for monitoring the technical condition of ship's TC - four-stroke engines equipped with BEU for thermal and vibration parameters obtained from portable diagnostic complexes of manufacturers. The development of a TC defect with existing diagnostic methods is almost impossible to detect.
