Abstract

1405433 Silencers AUTOIPARI KUTATO INTEZET 9 Aug 1972 [10 Aug 1971] 37066/72 Heading F1B A silencer for an I. C. engine comprises a polyhedral housing with space dividing members 6 arranged to define with walls of the housing three acoustic impedance units in flow series (an acoustic impedance unit consisting of intake conduit, chamber and outlet conduit and where two or more such units are in series the most upstream intake conduit and the most downstream outlet conduit may be mere openings) there being channels 45 of pre-selected configuration and dimensions in the conduits 4 and 5 joining the chambers of successive impedance units. Chambers 1, 2, 3 are the chambers of the three impedance units and the inlet and outlet openings 8 and 9 form the intake and outlet conduits.
