APPARATUS AND METHOD FOR DECREASING NITROGEN OXIDE EMISSIONS FROM INTERNAL COMBUSTION POWER SOURCES

摘要

Apparatus is disclosed herein for reducing engine nitrogen oxide emissions by mixing hydrogen prepared from a portion of engine fuel within a simple burner The apparatus includes a burner (20) having an internal combustion chamber (25) for receiving either a portion of a gaseous fuel or liquid fuel (24) for mixture with air (26) and subsequent ignition by a spark plug. A mixing chamber (30) is included having a series of baffles against which injected air and fuel vapors impinge causing thorough and complete air/fuel blending into a mixture subsequently ignited and burned. and then discharged into the combustion chamber of the engine itself A pre-heating arrangement is provided for raising the temperature of the air/fuel mixture via a heat exchanging process with the combustion gases in the combustion chamber.
