Temperature conditions of mechanical activation and dispersion of additives for engine fuel and oil
The efficient operation of vehicles is based on the use of fuel and engine oil with high specific characteristics, which is primarily due to the correct selection and combination of various types of additives. The mechanical activation of molybdenum disulfide (MoS<sub>2</sub>) and multiwalled carbon nanotubes ( MWNTs ) is possible both in a liquid (fuel or engine oil) and in a dry state with a subsequent mixing stage. The comparison of two methods of mechanical activation and dispersion by the parameters of the temperature field is carried out. To study the distribution of the temperature field, a non-contact measurement method based on the use of a Testo-875-1 thermal imager was used. The use of mechanical activation and mixing in the case of a rotating electromagnetic field provides an increase in mixing efficiency while maintaining the required temperature condition, which does not lead to destructive processes in engine oil and diesel fuel. The use of a rotating electromagnetic field makes it possible to reduce the temperature condition from 78.4 °C to 53.5 °C.
