  Forcing engines along with the positive properties – an increase in power within 5-50% has a significant drawback – a significant increase in the number of failures turbochargers. The main causes of failures are: failure of operators to start and stop; violation of maintenance standards; high stochastic loading modes 10-150%. The use of the lubrication system of a turbocharger of an internal combustion engine with an autonomous lubricating and braking device and an automatic control system for the braking of a turbocharger rotor excludes the occurrence of coking of residual lubricating oil in the channels of the turbocharger lubrication system when the internal combustion engine stops suddenly in the turbocharger rotor running-out mode, bearing turbocharger, as well as adjustable (temperature) feed to the turbine inlet about a turbocharger wheel compressed by a pump wheel of an air turbocharger. This leads to a decrease in the temperature of the turbine parts. At the same time, the operational reliability of bearings, the rotor, the hull and the turbocharger as a whole is increased. The use of prototypes of an autonomous lubricating and braking device on autotractor and combine diesels of machines allowed reducing the number of failures of turbochargers by 10-15%.
