Analysis of the pollutants, including polycyclic aromatic hydrocarbons emitted by the internal combustion engine powered by pyrolytic oil

Abstract

Possibility of powering the compressed combustion engine, 1.9 TDI produced by Volkswagen concern by pyrolytic oil was presented. Three blends with different pyrolytic oil and diesel content were prepared. To compare additionally diesel oil was tested. In researches measurements of concentrations pollutants emitted from the engine such as soot, NOx, CO, CO2 and PAHs were carried out. Also fuel consumption for each fuel was measured. Tests were conducted in chosen engines operation points: two values of rotation speed (1500 and 3000 rpm) and 6 values of torque from minimum value to 150 Nm every 30 Nm. In researches different methods and devices were used such as chromatography method, exhaust analyser and smoke meter. Studies have shown that it was possible to supply the engine by mixture of pyrolytic oil and diesel, but it was justified only in under certain conditions related to the composition of the mixture.
