Exhaust pipe
Pipe lengths
Dimension B: For Stage IV/Tier 4f engines, the exhaust gas temperature may drop
too much in the system if the total length between the turbocharger and SCR catalytic
converter intake exceeds 3.5 metres. There is then a great risk that the engine will go
into heating mode, which can increase fuel consumption. The maximum permitted
exhaust gas temperature reduction is indicated in 01:04 Exhaust system.
