Interkuler - the general information

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

Air, being compressed in a turbokompressor, heats up. Partsialny pressure of oxygen thus falls. For prevention of it, the interkuler after whom the cooled air arrives in the inlet pipeline is applied.

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