TURBOCHARGER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a turbocharger system in which the seizure of a revolving shaft can be suppressed.SOLUTION: A turbocharger system 1 comprises: a turbocharger 20 having a turbine shaft 22; an air bearing 24 for journaling the turbine shaft 22 rotatably by utilizing air sucked by the rotation of the turbine shaft 22; an air supply part 30 for supplying air to the air bearing 24; and an ECU 50 for controlling the air supply part 30. The ECU 50 causes the air supply part 30 to supply air to the air bearing 24 so that the turbine shaft 22 rotates at a first threshold value or higher at least at a restarting time of an engine 100 after the idling stop of the engine 100 has been performed.SELECTED DRAWING: Figure 1
