The charge air cooler design comprises two
sections, in which part of the charge air is fed
via a through duct, connected to a space-sav-
ing pipe, to the section of the other charge air
cooler which is fitted with cooling fins.
The rest of the charge air is fed directly
through the cooling fins, via a separate pipe,
to the second charge air cooler and into the
through duct.
Charge air cooler
Engine and gearbox
The existing series connection of the two
charge air coolers for the 110 kW engine is
inadequate for the 132 kW engine with its
high air throughput.
A new charge air cooler design was devel-
oped, in order to ensure optimal charge air
flow.
