Abstract
Abstract Internal combustion engine hot exhaust gas flow is treated to reduce the oxide content and increase the O2 content of the gases by A. EFFECTING INTIMATE CONTACT OF THE HOT GASEOUS FLOW WITH CONFINED COPPER CONTAINING STRIP MATERIAL, AND B. ELECTRICALLY ENERGIZING THE MATERIAL AT HIGH VOLTAGE DURING SAID CONTACT.
