The exhaust gas temperature and emissions of CO, NOx and SO2 are measured by an R-type thermocouple and TESTO 350-XL gas analyzer respectively. The oil of soybean, sunflower, canola and corn are used in transesterification process of biodiesel. The results show that maximum of temperature, NOx emission and SO2 emission are achieved for the combustion of sunflower methyl ester and corn methyl ester blends with gasoil in contrast with combustion of soybean methyl ester and canola methyl ester blends with gasoil. Also the minimum of CO emission is reached for combustion of these fuels.
