AbstractThis article presents the impact of biofuel for compression-ignition engines, produced with the use of innovative production technology, on the emission of toxic substances. The innovative production technology of biodiesel does not generate by-products, eliminating the need for development glycerol fraction and toxic methanol, substances inconvenient for environment. This technology is not currently well known and not used on an industrial scale. The essence of this technology is to carry out the transesterification of triglycerides and methyl acetate in special conditions and with using an alkaline catalyst. The only product of this technology is a mixture of fatty acid methyl esters and glycerol triacetate (no by-products). In the first part of the article, selected physical and chemical properties of such biofuel in comparison to the limits specified in the standard quality requirements for this type of products (EN 14214) were discussed. In the next part, the results of empirical studies were evaluated, showing the influence of speed and load conditions in test engine Perkins 1104C-E44TA on concentrations of harmful components in the exhaust gases such as carbon monoxide, nitrogen oxides, hydrocarbons, particulates. Engine tests were performed with using biofuels selected by the authors. The measurement system, consisted of an AVL CEB II gas analyser and MEXA-1230PM device for measure of particulate matter in real time, to measure the concentrations of toxic exhaust components was used. Based on the concentration of toxic components of exhaust gases according to Test C1 according to ISO 8178, the emission of the above-mentioned normalized toxic components of exhaust gases was determined. In the final part of the article, the results of empirical studies on the concentrations of toxic exhaust gases in the linear-point diagrams, and emission in the bar chart diagrams were presented.
