3.1.3 System of charged air cooling

Intermediate cooling of charged air is a means, increasing density of air charge, coming to engine cylinders, thus enabling more effective burning of a bigger amount of fuel in the cylinders and as a result ensuring increase of power with decrease of specific fuel consumption. An air-cooled cooling system is used in the engine, with a plate-fin air cooler (radiator) 5 (figure 3.1.5). The charged-air cooler 5 is mounted in front of the water radiator and is linked to the turbocharger and engine intake manifold through the system of air pipelines 3 and pipes 2, 4, joined by clamps 1. The CAC is an air heat exchanger, consisting of a core as finned aluminum pipes, tanks and connection tubes. Air is delivered to the CAC from the turbocharger, cooled inside it to improve power-efficient and ecological parameters of the engine and further comes to the engine air intake.
