Abstract: Replacing the alkyl lead derivatives with aromatic hydrocarbons and additives in modern reformulated fuels to improve internal combustion engine performance, lower fuel consumption, increase power, and improve emission characteristics have resulted in the emission of large quantities of BTEX (benzene, toluene, ethylbenzene, and xylene) compounds into the atmospheric compartment. In this research, how the different working regimes of an experimental engine affect the BTEX compound concentration levels was observed to evaluate the quantities emitted during the movement of a passenger car in urban driving conditions. The target compounds were analyzed in exhaust gas samples using the Photovac Voyager-mobile GC (Waltham, MA, USA). This experimental research demonstrates that optimizing engine operational parameters significantly reduces the concentration levels of BTEX compounds in exhaust gas mixtures by adjusting specific working regimes, contributing to better emission characteristics and promoting sustainable transportation solutions. The most significant effect of the independent increase in air quantity in the feed mixture is realized through the decrease in concentration levels of toluene in the exhaust gas mixture of approximately 81%. A significant reduction in concentration levels is achieved with m,p-xylene (79%) and o-xylene (79%) as well, whilst the lowest effect has been noted with benzene (73%) and ethylbenzene (71%).
