Combined air filter and air intake, for an IC motor, has a curved air intake pipe within the geometry of the assembly, with acoustic units at the pipe loop

The combined air filter (9) and air intake, for an internal combustion motor, has an air intake pipe (2) within the geometry of the combined unit with a pipe loop (3), to give the required acoustic pipe length of 750 mm with perforations (5). Further acoustic units (6) are within and/or at the pipe...

Summary:The combined air filter (9) and air intake, for an internal combustion motor, has an air intake pipe (2) within the geometry of the combined unit with a pipe loop (3), to give the required acoustic pipe length of 750 mm with perforations (5). Further acoustic units (6) are within and/or at the pipe loop. The acoustic unit within the pipe loop can be combined with a shunt resonator matching a noise frequency of 95 Hz. Die Erfindung betrifft eine Luftfilter-Ansaugkombination für einen Verbrennungsmotor, bei der ein Ansaugrohr (2) innerhalb der Geometrie der Luftfilter-Ansaugkombination derart angeordnet ist, dass mit einer Rohrschleife (3) eine akustisch notwendige Rohrlänge hergestellt wird. Innerhalb und/oder an der Rohrschleife (3) können weitere akustische Bauelemente (6) angeordnet werden, wobei als ein weiteres akustisches Bauelement innerhalb der Rohrschleife zum Beispiel ein Nebenschlussresonator (6) angeordnet ist.
