Abstract
Pollutant particles, particularly lead particles, are removed from engine exhaust gases by passing the gases successively through three aligned chambers, of which the first and third contain wire mesh or expanded metal packings, while the second chamber is divided by a deflecting baffle which deflects the partially cleaned exhaust gases downwards to deposit particles in the bottom of the second chamber.
