Radiator of nadduvochny air

The fresh air which is soaked up via the air filter is accelerated in the compressor and condensed. Not only consolidation, but also located in a stream of exhaust gases (and, therefore, hot) a turbocompressor provide the subsequent heating of the soaked-up air. At full loading temperature of the soaked-up air can rise to 110 °C.

The radiator of nadduvochny air is connected between a turbocompressor and an inlet collector of the engine. It can cool the soaked-up air after compression process approximately on 50 °C before it comes to the engine. At the expense of it filling of combustion chambers improves and, therefore, power increases.
