The sound generated by drive units is one of the aspects that are addressed in sustainable transport development strategies. The regulations of the European Union, which indicate the ecological aspect of the use of internal combustion engines as one of the most important, also refer to the level of sound emission generated by these engines. The use of alternative fuels to power combustion engines allows not only to reduce the toxic components of exhaust gases, but also to reduce the noise they generate during operation. The manuscript presents the study of a drive unit powered by mixtures of diesel oil and fatty acid methyl esters, in which the software regulations of the control system were modified. Studies have shown a decrease in the level of sound emission when powered by alternative fuels.
