Exhaust System
The exhaust system is completely redesigned for the N62B44 engine. It has been opti-
mized in terms of cylinder filling, scavenging, sound level and rapid catalytic converter light-
off.
Exhaust Manifold with Catalytic Converter
Each cylinder bank is equipped with a four into two into one exhaust manifold. The mani-
fold and the catalytic converter housing together form one component. A ceramic-bed pre-
catalytic converter and a ceramic-bed main catalytic converter are arranged one behind the
other in the catalytic converter housing.
The mounting for the broadband planar oxygen sensors (Bosch LSU) and the secondary
oxygen sensors is located in front of and behind the catalytic converter.
