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.
