Abstract:Even though current use of biodiesel in power motor vehicles is considered an unsustainable future direction, there are difficulties in implementing the currently proposed concepts on the future development of internal combustion engines (hydrogen, fuel cells and hybrid systems) to tractors because of specific construction, design and their specific activity. To truly become a competitive fuel on market, compared with fossil fuels, biodiesels must optimize parameters related to characteristics of density, viscosity, freezing point and especially the specific calorific value. Research carried out so far has highlighted differences in the characteristics and physical parameters of biodiesel and fossil fuels (diesel oil). Thus, particularly high values of the freezing (-12°C biodiesel and -20°C diesel fuel) leads to worsening environmental process starting at low engine temperatures. This paper presents the working principle, technical data system and the experimental results obtained by using the heat transfer properties of ultrasounds propagation in liquids, in order to improve cold start process of compression ignition engines.
