Interkuler - the general information

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

Air, contracting in a turbocompressor, heats up. Thus the partsialny pressure of oxygen falls. For prevention of it, the interkuler after whom the cooled air comes to the inlet pipeline is applied.

Compressed air comes not to the inlet pipeline (as on ordinary diesel engines), and in an interkuler. Interkuler is located in 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. Interkuler looks as well as a radiator of the cooling system. From an interkuler air moves in the inlet pipeline.
