Radiator of nadduvochny air

The fresh air which is soaked up through 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 turbokompressor provide the subsequent heating of soaked-up air. At full loading the temperature of soaked-up air can rise to 110 °C.

The radiator of nadduvochny air is connected between a turbokompressor and an inlet collector of the engine. It can cool soaked-up air after compression process approximately on 50 °C before it will arrive in the engine. At the expense of it filling of chambers of combustion improves and, therefore, the capacity raises.
