One secondary air valve for each cylinder bank is screwed to the
back of the cylinder heads (see also Engine views in the Intro-
duction section for the N62).
The SLV is opened by the pressure generated by the secondary
air pump. The secondary air is led through a pipe to the
secondary air ducts.
The SLV is closed as soon as the secondary air pump is
switched off, preventing exhaust vapours from flowing back to
the secondary air pump.
