ОЦЕНКА ТЕПЛОВОГО БАЛАНСА В ТЕРМИЧЕСКОМ НЕЙТРАЛИЗАТОРЕ ДЛЯ СНИЖЕНИЯ ТОКСИЧНОСТИ ОТРАБОТАВШИХ ГАЗОВ

Abstract

According to statistics, the share of automotive equipment accounts for up to 60 percent of harmful emissions. Gasoline engines play an important role in the pollution of the air basin. In the areas of operation of vehicles, there is an increase in the concentration of toxic substances. (Research purpose) The research purpose is in creating an effective means of cleaning exhaust gases, which has an increased resource and little impact on the power and fuel-economic indicators of the engine, and studying the processes occurring in thermal neutralizers, for their subsequent use on mobile agricultural and industrial equipment. (Materials and methods) Authors used the calculating method for the main indicators according to the method of thermal calculation of the internal combustion engine. The article identifies and analyzes the most significant processes in the device for reducing toxicity, established their relationship with temperature and the possibility of using them in optimizing the device. (Results and discussion) Authors performed calculations of heat losses in the thermal neutralizer at different thicknesses of the thermal insulation layer for different operating conditions. (Conclusions) Based on the analysis of literature sources and conducted research, it was found that tractor engines play a large role in the pollution of the air basin. The study of the features of various exhaust gas treatment systems has shown that the development of a device that combines the functions of a thermal neutralizer has become promising. According to the equations, the heat losses in the thermal neutralizer were calculated at different thicknesses of the thermal insulation layer for different operating conditions. As the calculations show, an increase in the thickness of the thermal insulation over 10 millimeters seems impractical because further reduction in heat loss occurs slightly, while increasing the size and cost of the structure.
