Exhaust gas reactor

Claim 1

An exhaust gas reactor for reducing the concentration of hydrocarbons and carbon monoxide in the exhaust gas from an internal combustion engine comprising A. a heat insulated elongated casing having 1. inlet holes, and 2. an outlet between its extremities, said casing being otherwise closed; B. a reaction chamber concentrically positioned at the interior of the casing, having 1. gas inlet holes, and 2. peripheral openings axially removed from the inlet holes, said reaction chamber being otherwise closed; C. a deflector tube concentrically positioned between the reaction chamber and the casing 1. forming an inner annulus between the deflector and the reaction chamber, 2. forming an outer annulus between the deflector and the casing, 3. providing open communication at its extremities between the inner and outer annulus, 4. having holes in alignment with inlet holes in the casing and the reaction chamber, and 5. provided with at least one bypass hole which is a. at a location axially different from that of openings in the reaction chamber, and b. positioned away from the outlet of the casing; D. inlet pipes extending through inlet holes in the casing, deflector tube and reaction chamber in communicating connection with the reaction chamber; the reactor providing a series of communicating openings which extend through the reactor in a path which is through the inlet pipes into the reaction chamber, out of the peripheral openings and into the inner annulus, then to a first continuing path which proceeds axially along the inner annulus, through open communication at the extremities of the deflector and along the outer annulus to the casing outlet, and to a second continuing path which is along the inner annulus to a bypass hole, through the bypass hole into the outer annulus and along the outer annulus to the casing outlet.
