The charge air cooler (110/2) is connected to a separate coolant circuit with a low temperature cooler (110/10) and an electrical charge air cooler circulation pump (M44). 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 recirculation pump on the charge air cooler.

The cooled charge air improves the degree of filling of the cylinder and lowers the exhaust gas temperature (lower generation of NOX). There is a second auxiliary low temperature cooler (110/11) installed on the type 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.
