INTERNAL COMBUSTION GAS GENERATOR

摘要

Apparatus is disclosed herein for reducing engine nitrogen oxide emissions by mixing hydrogen prepared from a portion or all of engine fuel within a simple burner. The apparatus includes an insulated burner (10) having an internal combustion chamber (17, 40) for receiving either a portion of or all the gaseous fuel or liquid fuel for mixture with air and subsequent ignition by a spark plug (27). The chamber is within a feed preheater assembly. A mixing chamber (17, 40) is included having a series of baffles (22, 23, 32, 37) against which injected air and fuel vapor 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. The pre-heating assembly (15, 31) raises the temperature of the incoming air/fuel mixture via a heat exchanging process with post combusted gases from the combustion chamber. The apparatus improves operability and performs by conserving energy by insulating the total burner, placing the burner section within the feed preheater assembly, and locating the feed mixture flow of the preheater adjacent to the outer insulation (12); and hydrogen output may be increased by reaction between carbon monoxide and water produced by the main reaction or added separately.
