Abstract

In this paper, the possibility of implementation of the infrared thermography as a technical systems’ diagnostic method is investigated. The infrared thermography as a contemporary method was used for visualization of the working conditions in the piston of an automotive engine as well as for analyzing of the thermal changes the piston sustained under exploitation. The obtained results were used to define the properties of the alloy used for production of the piston for a highly loaded diesel engine. In such way, the problems caused by erroneous choice of the material could be avoided.

Kurzfassung

In dieser Veröffentlichung wird die Möglichkeit untersucht, die Infrarot-Thermografie als Diagnoseverfahren für technische Anlagen anzuwenden. Die Infrarot-Thermografie als heutiges Verfahren wurde zum Sichtbarmachen der Arbeitsbedingungen im Kolben eines Kraftfahrzeugmotors sowie zur Analyse der thermischen Veränderungen angewandt, die der Kolben während seiner Nutzung erfuhr. Die Ergebnisse, die man erhielt, wurden angewandt, um die Eigenschaften der Legierung zu definieren, die zur Herstellung des Kolbens für einen stark belasteten Dieselmotor verwendet wurde. Auf eine solche Weise konnten die Probleme, die durch eine falsche Wahl des Materials verursacht werden, vermieden werden.
