The system has been designed to lower the temperature of the supercharing air before it i s sent to the cylinders.
The air is drawn in and filtered by means of two dry filters and introduced inside the turbochargers.
The air is compressed, with a consequent increase in temperature and, after having been collected in a single pipe, it is sent to the
intercooler.
This heat exchanger, which the flow of air produced by the fan fastened axially and driven by the crankshaft comes into contact
with, cools the compressed air and sends it, via the pipe, to the main manifold and from there to the two intake manifolds, located
on each bank.
On versions for cold climates, there are two pre-heating heaters on the main manifold designed to assist engine starting at low
temperatures (ambient temperature up to - 25˚C).
Heater voltage: 24V DC
Peak current: 240 ± 50˚
Stabilization current: 83 ± 12A.
Together with the above mentioned heaters, these versions also have a resistance for heating the engine lubrication oil and a fuel
heater on the diesel pre-filter.
