The subject of the article is the identification of factors behind the incorrect operation of a car turbocharger that, in longer perspective, lead to the damage of the device. Due to the operating principle and design features, the device works with many engine systems – intake, exhaust, lubrication systems and also, increasingly more often, with the cooling system. A multitude of relations, complexity, and working conditions are reasons due to which the device is sensitive to disturbances of quality parameters of the working media (e.g. oil). In the article based on the selected causes of damage of turbochargers, we focused on the following initiating event, concerning the bearings lubrication system, which is clogged oil strainer. The authors aims at performing an analysis allowing to increase the detectability of emerging malfunctions that lead to deterioration of operating conditions of the device. For this task tool such as ETA (Event Tree Analysis) was used. It is a tool for assessing system and process safety. It facilitates detecting potential risks, as well as relations existing between actions or events. This method explores the path from the initiating event to the outcome (most often representing the immobilization of the tested object), with particular emphasis on intermediate stages affecting the technical condition of the object. Unlike the FTA analyses, which have a deductive nature, the ETA analysis is inductive. The analysis of the obtained results, supported with validation by means of ETA, allowed proving that, given the current state of knowledge and advancements in technology, it is possible to apply additional sensors for monitoring the operation of a turbocharger. The proposed modifications were considered minor design changes that significantly increase the reliability of the device.
