FIELD: air purification.
SUBSTANCE: invention can be used in air purification systems of internal combustion engines. The combined air filter comprises a housing (1) with inlet and outlet pipes (2) and (3), a filter element (4) located in the housing, an attachment (5) of the housing to the engine, a particle charging unit (6), which is a single-zone electrofilter, and a regeneration device (7). At the entrance to the particle charging unit (6), there is a distribution chamber (8) with guide plates (9) inclined to the longitudinal axis of the housing (1). The regeneration device (7) communicates with the engine compressor by means of nozzles (10) and is equipped with a device (11) for switching on the gas supply. The nozzles (10) are evenly spaced along the perimeter of the housing (1) in the area of the filter element (4).
EFFECT: improving the air purification process.
