Abstract
Abstract An anti-pollution device includes a cylindrical chamber attached in line with the exhaust of an automotive vehicle, which in conjunction with the velocity and heat of emitted exhaust gases further heats and burns emitted gases exiting the tail pipe into relatively harmless non-polluted vapors. The chamber is affixed in line with the exhaust tail pipe of an automotive vehicle near the exhaust manifold and consists of a cylindrical outer and inner shell with insulation therebetween with a three stage system constructed internally along the length of the chamber for progressively heating and burning of exhausted gases and finally cooling thereof. In one form the first stage consists of a spiraled ceramic cone for accelerating and concentrating the exhaust fumes into the second stage consisting of a series of ceramic rings for burning of exhaust gases, the burned exhaust fumes then passing therefrom into the third stage consisting of a porcelain lined cooling pipe for cooling of exhaust gases prior to their emission out of an automotive vehicle. In another form there is a source of energy for heating the gases in a Venturi tube combustion section by igniting the gases, and there is further provided an arrangement for introducing controlled amounts of air in the combustion section to enhance combustion of the gases.
