Solid particles (PM) contaminate the filter surfaces and enter the pores, as well as settle on the surfaces of catalysts and deactivate them. Therefore, this article discusses the filter system and the cleaning system. The paper describes the requirements for what they should contain and provide, what properties and parameters the filter material should have, as well as catalytic converters that contribute to an increased level of cleaning. It is also shown that the system that filters exhaust gases must be resistant to vibrations of up to 150 Hz at an acceleration of up to 4 g. The filter system and cleaning system must be equipped with devices that ensure the regeneration of catalysts at the site of dismantling. The purification system must ensure that the emissions of the following harmful substances are reduced.

In modern conditions, internal combustion engines (ice) are the most popular power plant for a number of transport vehicles: cars, tractors, locomotives, river and sea transport vessels. Strict requirements of modern Euro-standards to the degree of "smokiness" of exhaust gases of diesel internal combustion engines and their toxicity contribute to the emergence of a dead end situation. It is almost impossible, using obvious technical solutions, to comply with the requirements of Euro-5 and Euro-6 standards while maintaining the acceptable growth in economic costs, internal combustion engines (ice) emit a significant amount of exhaust gases into the atmosphere, which is an environmental threat. The article considers the method of SHS technology and its advantages.
