PURPOSE:To prevent deterioration of lubricating oil in a bearing part, by introducing a jet stream of high pressure gas to a floating bearing part at stopping of an engine and blowing the lubricating oil accumulated in the bearing part with the jet stream to dry the bearing part. CONSTITUTION:During operation of an engine, a key switch 144 is placed in an ON position and a solenoid 132 is excited. This causes a shut off valve 134 to close. Intake air pressurized by a compressor of a turbocharger is partially accumulated in a surge tank 130 through a supercharge intake pipe 140. When the key switch is turned to an OFF position to stop the engine, an oil pump 108 is also stopped. Action of a delay timer 142 causes the solenoid 132 after opening of the key switch to open after elapsed a prescribed time, and high pressure air in the surge tank is injected toward an oil inlet pipe 112. |
