Analysis of the emissions of volatile organic compounds from the compression ignition engine fueled by diesel-biodiesel blend and diesel oil using gas chromatography

Abstract This paper describes the procedures of the analysis of pollutant gases, as volatile organic compounds (benzene, toluene, ethylbenzene, o -xylene, m -xylene and p -xylene) emitted by engines, using high-resolution gas chromatography (HRGC). In a broad sense, CI engine burning diesel was compared with B10 and a drastic reduction was observed in the emissions of the aromatic compounds by using B10. Especially for benzene, the reduction of concentrations occurs on the level of about 19.5%. Although a concentration value below 1 μg ml −1 has been obtained, this reduction is extremely significant since benzene is a carcinogenic compound.
