Abstract

A post-combustion engine exhaust gases absorber is an apparatus that scrubs greenhouse gas emissions and other pollutants from a post-tailpipe combustion engine exhaust. The apparatus reduces pollutants that could enter the atmosphere to reduce the environmental impact of the combustion engine. The apparatus includes an elongated housing, a distal dry filter, a biofilter, a distal motorized exhaust fan, a wet filter, a controller, and a portable power source. The elongated housing allows the apparatus to be attached to the exit of the combustion engine exhaust system. The distal dry filter, the biofilter, and the wet filter collectively remove the pollutants from the exhaust flow. The distal motorized exhaust fan drives the exhaust flow through the elongated housing so that the exhaust flow moves through the distal dry filter, the biofilter, and the wet filter. The controller and the portable power source enable the autonomous or semi-autonomous operation of the apparatus.
