Molecular diffracter and its use in feeding internal-combustion engines

摘要

Molecular diffraction device operating in the gas intake vein downstream of the carburator or of the injection system of internal combustion engines, comprising a support frame (10) for the diffraction structure which is itself secured therein by a fixing system. The device according to the invention comprises at least one diffraction element or stage (19) with a conical apex situated upstream of the structure comprising communication grooves (25) or transfer channels profiled in the gas flow direction. Each transfer channel has one or a plurality of cylindrical or square wells (26) drilled perpendicularly or obliquely to the structure axis and a diffraction slot (26 bis), which terminates the transfer channel at its lower part. The device further comprises a resonance stage (27) free of any element favouring the swirling of the gas mixture. Next to the resonance stage, there is provided a second diffraction stage (29) having a configuration similar to that of the first diffraction element or stage. The present invention implements the molecular diffraction which effects the dissociation of molecular structures into a multitude of smaller structures which have a total surface larger than the surface of the initial structure, and therefore a larger oxidation surface favouring a better combustion, and consequently reduced pollution and consumption.
