PURPOSE: A bearing burning and sticking prevention system is provided to reduce fuel consumption by stopping the turbo-charger in a shortest time period when an engine is turned off to park an automobile. CONSTITUTION: A turbine housing(5) includes an exhaust gas inlet(1) for taking an exhaust gas, an exhaust gas outlet(2) for discharging the exhaust gas taken by the exhaust gas inlet, an intake air inlet(3) for introduction of outdoor air, and an intake air outlet(4) for sending the intake air to a cylinder of an engine. A shaft(7) being supported by a bearing(6), and a turbine wheel(8a) and a compressor wheel(8b) connected to the shaft are arranged within the turbine housing. An oil feed port(9) for feeding oil to the bearing supporting the shaft, and an oil return port(10) are communicated with each other. The bearing is connected with a cable which is connected to a contact(12) of a starting switch(11). A solenoid valve(13) of the oil return port is connected to a timer(14). |
