Air filter for internal combustion engines

The air filter for an internal combustion engine includes a filter element inside a filter housing divided into an inlet air chamber, consisting of an air entry section (15) and collecting section (12), and an outlet air chamber. A first set of tubes (41) is installed in the inlet air chamber, with the tubes connecting the air entry section and collecting section. A passage (50) formed as a Venturi nozzle is located in the outlet air chamber. The passage in the outlet air chamber widens with a slight gradient from a narrow point lying behind its air inlet in the direction towards its air outlet, divides the outlet air chamber into a collecting section (13) and channel section (14) lying inside the passage, and connects the collecting section to the air outlet opening (11).
