DEVICE FOR PURIFICATION OF DIESEL ENGINE EXHAUST GASES

To ensure high quality and productive work of employ-ees, it is necessary to achieve the target parameters of the microclimate and to exclude harmful and toxic substances in the atmosphere of the working area of agricultural prem-ises of a closed volume and air exchange. The main rea-son for the distortion of the air-gas regime of the room is the use of agricultural machines in closed industrial prem-ises (warehouses, storage facilities, livestock facilities, etc.). As a result, there is a decrease in the quality of prod-ucts and working conditions at agricultural enterprises, as well as a reduction in the operational life of structures. To-day, in agricultural machinery, diesel engines are most often used as power units which, unlike gasoline engines are more economical, and also reduce the harmful impact on the environment. But, despite this, the operation of die-sel engines still causes the accumulation of harmful com-ponents in the atmosphere of the room which negatively affects the health of the staff. The analysis of the designs of devices for exhaust gas purificationof internal combus-tion engines revealed the problems that affect the efficien-cy of the purification. The most significant problems are as following: large weight and dimensions, reduced efficiency of the neutralizers when the engine is running at modes close to the nominal ones, and large gas-dynamic re-sistance. To solve these problems, the design of a device for exhaust gas purificationin diesel engines was devel-oped. The use of this utility model will increase the efficien-cy of the device for exhaust gas purification. It will improve the environmental performance of the diesel engine reduc-ing emissions of harmful substances and soot into the at-mosphere.
