Charge air cooler function - GF09.41-P-3100-01AM
Shown on charge air cooling models 220, 463
The charge air cooler is connected to a separate coolant circuit with a low temperature radiator and electrical charge air cooler circulation pump.
The air heated during the charge operation dissipates its heat to the coolant which flows through the charge air cooler.
The coolant is subsequently cooled in the low temperature cooler and then pumped back to the charge air cooler over the circulation pump for charge air cooler.
Due to charge air cooling, the volumetric efficiency of the cylinder is improved and the level of NOX emissions reduced.
There is a second auxiliary low temperature cooler installed on the models 220, 463 in addition to the normal low temperature cooler.
The water cooling makes it possible to achieve a higher efficiency compared to air-cooled charge air coolers.
