Table 15.07.02: Exhaust gas pipe diameters and exhaust gas mass ow at various velocities
The exhaust gas pipe diameters listed in Table
5.07.02 are based on the exhaust gas ow ca-
pacity according to ISO ambient conditions and
an exhaust gas temperature of 250 ºC.
The exhaust gas velocities and mass ow listed
apply to collector pipe D4. The table also lists the
diameters of the corresponding exhaust gas pipes
D0 for various numbers of turbochargers installed.
