Exhaust gases purification device and method for internal combustion engines

Abstract

An exhaust gases purification device for internal combustion engines, of the kind that includes a duct which channels gases from the engine exhaust manifold, and injects them into the device, characterized by comprising a quiet chamber (wherein gases expand), then a first standard filter, a buffer plate, then a second filter, and then a centralizer-diffuser assembly where the gas flow is contacted with two external cold air drafts and part of the polluting gases are channeled into a turbulent chamber, from which they are fed into the engine as intake gases, the remaining flow being discharged into an tube ending in a atomizer, and from there into an exhaust tube; said turbulent chamber comprising an engine port portion that discharges into fixed buckets, where gases are expanded and channeled into the atomizer that comprises a gas recovery outlet back into the engine.
