Abstract (en)
[origin: DE19510602C1] The exhaust system is branched to collect the exhaust gases of a multicylinder IC engine. The individual pipe sections (1,2,3,4) on the first collection level (16) are equal in cross-section and in angle. The second stage pipes (5,6) have Y-sections at their top to integrate two of the first pipes into one second stage pipe, the joint achieved via a fillet weld (15). One of the second stage pipes has a further Y-section to join the second stage into the single third stage pipe (18). The other second stage pipe (6) is inserted into this larger dia. Y-section (11) and again sealed via a fillet weld around the circumference.
