The intercooler - the general information, removal and installation

General information

The intercooler in fact is the heat exchanger intended for decrease in temperature of the air passing through it.

Air, contracting in a turbocompressor, heats up. At the same time the partial pressure of oxygen falls. For prevention of it, the intercooler after which the cooled air comes to the inlet pipeline is used.

Compressed air comes not to the inlet pipeline (as on ordinary diesel engines), and in the intercooler. The intercooler is located in a forward part of a motive compartment and is blown naturally at the movement of the car. Air from the compressor comes to the lower part of a cooler and in process of the movement is cooled up. The intercooler looks as well as a radiator of the cooling system. From the intercooler air moves in the inlet pipeline.
