Model detekcije benzena, toluena, etilbenzena i ksilena u izduvnim gasovima motornih vozila primenom gasne hromatografije u funkciji procene zagađenja ambijentalnog vazduha

Abstract

U okviru doktorske disertacije opisane su jedinstvene fiziĉko-hemijske karakteristike grupe supstanci benzena, toluena, etilbenzena i ksilena koje pripadaju istraživanjima najnovijeg trenda nauĉne javnosti. Posebno su opisane perzistencija i pseudoperzistencija, transport, distribucija i negativan i toksiĉan uticaj na zdravlje ĉoveka i životnu sredinu. Sprovedena su eksperimentalna istraživanja zavisnosti koncentracionih nivoa BTEX jedinjenja u izduvnim gasovima i operativnih parametara eksperimentalnog motora SUS. Na osnovu dobijenih rezultata eksperimentalnih istraživanja definisan je emisioni model BTEX jedinjenja simulacijom kretanja putniĉkog automobila Fiat Punto Classic u skladu sa NEDC ciklusom koji na odgovarajući naĉin reprezentuje standarde uslove vožnje u evropskim gradovima.

In this thesis, the unique physicochemical characteristics of a group of substances consisting of benzene, toluene, ethylbenzene and xylene have been described. Special emphasis has been placed on their characteristics of persistence and pseudopersistence, transport, distribution and the negative and toxic influence on human health and the environment. The experimental research of the interdependence of the concentration levels of BTEX compounds in the exhaust gases and the operational parameters of the experimental IC engine has been conducted. Based on the experimental research results, the emission model of the BTEX compounds has been defined by a simulation of movement of a Fiat Punto Classic passenger car in accordance with the NEDC cycle, which appropriately represents the standard driving conditions in European cities. Research conducted within the thesis represents the newest trend of investigation in the scientific world.
