Identification of operating fluids with fingerprint method utilization

Popis výsledku v původním jazyce

A lot of operating substances and materials are used for vehicle powertrain systems. For example, liquid fuels (diesel, petrol), lubrication oils (engine, transmission), lubrication greases, coolants and antifreeze additives, brake fluids, power transmission fluids, cleaning agents for parts of vehicles and many more. The identification of operating fluids is easy due to original packaging and its indication, if they are stored properly. However, operating fluids are very often stored in packaging, which is not marked. Therefore, sensory methods are applied: the operating fluids are distinguished from each other according to their appearance, colour, smell, flammability, foamability and others. Such subjective methods require very skilled assessment staff. In cases of contaminated or mixed operating fluids these sensory methods are usually insufficient. Therefore, this paper is concerned with a proposal of the fingerprint method for operating fluids with utilization of infrared spectrometry. The working principle of the method is measurement of infrared radiation absorbed by analysed substance with wavelengths from 600 to 1800 cm-1. The infrared spectrum is the analytical result of a specific substance. The final step is the comparison of a measured substance with the atlas or a kind of database of familiar operating fluids. Several spectra of operating fluids are mentioned in the last part of the paper. Results of the research have shown that the fingerprint method has proven its ability to clearly distinguish the kind of operating fluid from the others and determine the level of possible contamination with another operating fluid. In many cases it is possible to determine the quality indicators of measured operating fluids.
