It is proved that the use of the braking device of the turbocharger rotor integrated in the intake system of the internal combustion engine, that has the estimated structural parameters, reduces the duration of the rotor running-out by 30-35 %, which thus makes it possible to reduce the clearance and the operating time of the hydro-accumulator with the exception of the surge phenomenon emergence in the compressor part of the turbocharger, thus avoiding the breakage of its parts. The estimated economic impact is in the range of 5080 thousand rubles for the season of the unit operation with the tractors of different unit power.
