Assessment of the change in structure-borne noise from the 4-cylinder diesel working process during its conversion to methyl ester of rapeseed oil
Abstract
The use of alternative fuels is one of the ways to reduce the noise of an internal combustion engine. The article examines the effect of rapeseed oil methyl ester (MERM) on the structure-borne noise from the working process, economic and environmental performance of 4-cylinder diesel. The results of studies of diesel noise when running on diesel fuel, pure MERM (B100 RME) and mixed fuels from 80% MERM and 20% DT (B80 RME), as well as from 20% MERM and 80% DT (B20 RME) are presented. The results of the study showed that noise decreases with increasing concentration of MERM in a mixture with diesel fuel, and the greatest effect (16.3 dB) is achieved when diesel is running on B100 fuel, but at the same time the economic and environmental performance of the engine deteriorates. According to the complex of engine parameters, it is most advisable to use fuel in the B80 RME range.
