Summary: | This research reviews the impact on emissions from the engine fueled with the fuel containing a large share of bio-components, in particular with 30% n-Butanol. The research was carried out using a diesel engine. It has been shown that it is possible to achieve a double positive ecological effect concerning CO<sub>2</sub> emissions. There was a decrease in CO<sub>2</sub> emission from the engine with the fuel contained a significant share of bio-carbon. At the same time, NO<sub>x</sub> and Filter Smoke Number (FSN) emissions have been reduced together (FSN in large percentage). Usually, if NO<sub>x</sub> emissions are reduced, FSN increases, and vice versa. The paper shows also that the use of n-Butanol (bio, but nonfood) in the future is more effective than larger amounts of higher fatty acids methyl esters, although the full withdrawal of these esters seems unjustified.
