Internal combustion engine exhaust gas cleaner including a vortex-type molecule separator

摘要

An i.c. engine exhaust gas cleaner consists of a tube and housing forming a continuous circuit (2, 3, 9, 10) with an intake (1) for the exhaust gases, and a vortex molecule selector (5, 6, 13) with its outlet (7) connected via a pipe (8) to the outside air. The inner chamber of the housing (9), in communication with the vortex chamber, contains the gas cleaning system (22, 27) and has its outleta (10) linked to the circuit zone (2) adjacent to the inlet. The gas cleaning system comprises a spiral (27) of a catalytic material, and a passage (22) connecting with a chamber (23) which collects the liquid and solid residues extracted from the exhaust gases and is emptied from time to time. The chamber is equipped with an ejector tube (25, 26) which creates a slight depression inside it.
