Abstract
A suction pipe for the intake air of an internal combustion engine, which has a pressure relieving site in the form a bursting geometry,for backfiring impacts in the suction pipe. In the event of backfiring, the sites of weakness,fail and the bursting geometry is flung into the buffer volume,, as a result of which the energy of the backfiring pressure wave is dissipated. As a result, further damage to the suction pipe is prevented, so that the emergency running properties of the internal combustion engine are retained. The proposed pressure-relieving sites have a high functional reliability, independently of the operating state of the internal combustion engine, particularly of the operating temperature.
