Exhaust gas catalyst neutralizing, at an IC motor, has structured flow channels with intersections and resonance chambers to give oscillations and a chain reaction in the gas flows

摘要

To neutralize exhaust gases from internal combustion motors, using a catalyst, there is a thermodynamic conversion with oscillations of the gas flows separated by a wall (6) and flow distributor (9,10) at a frequency not less than 5 kHz at channel (11,12) intersections. The structure has an array of parallel and serial resonance chambers (13,14) with restricted flows, as oscillation groups for the channels. The gas flows through the center (15) or corner gaps generate oscillations in the chambers at their natural frequency and the vertical overlap of flows at the intersections gives oscillations in the channels through aerodynamic interference regulated by the resonance chamber oscillations for a synchronized oscillation over the catalyst volume.
