MONITORING FUEL QUALITY IN THE TRANSPORT INDUSTRY.

Purpose: The aim of the article is to check whether there are indications that light waves can be used to monitor fuel quality. Design/methodology/approach: Tests of deposits released in fuels during long-term storage were carried out. The research involved observing with the unaided eye illuminated samples of fuels stored in glass vials. The research was qualitative in nature. Samples of diesel oil, gasoline were tested. The phenomena occurring in materials under the influence of aging processes were determined and the relationships between the tested material, its quality and the impact of light rays on the sample were explained using physic-chemical phenomena. Findings: The novelty of the article is to show that fuels after the storage process can significantly differ in quality from the starting material and that it is possible to monitor fuel quality using spectroscopic methods. Research limitations/implications: The research conducted is qualitative and not quantitative. Practical implications: It is suggested to use methods of continuous monitoring of stored fuels using light spectroscopy methods. Originality/value: It is to show that fuels from one manufacturer and stored in the same tank age at different times. Fuels have different properties and significantly differ in quality compared to the input material. Therefore, there is a real need for continuous monitoring of fuel quality. [ABSTRACT FROM AUTHOR]
