06 Exhaust / Turbocharging System
Turbocharging System
Charge air temperature at engine inlet see acceptance test sheet
Max. intake resistance 25 mbar (250 mm of water)
Exhaust System
On the 8- and 9-cylinder models, the cylinder next to the turbocharger goes to the multi-pulse
unit direct, so the exhaust temperatures of this cylinder are somewhat lower (see acceptance
test sheet).
Exhaust teperature after turbine see acceptance test sheet
Max. backpressure 25 mbar
