PROBLEM TO BE SOLVED: To provide a lubricating oil supply system capable of supplying lubricating oil to a turbocharger even when the lubricating oil cannot be supplied to the turbocharger via oil supply means (an oil pump is inoperative).SOLUTION: A lubricating oil supply system includes a lubricating oil passage 200 connected to an engine 100 so that lubricating oil circulating in the inside of the engine 100 can flow in and circulate, a turbocharger 320 arranged in the halfway of the lubricating oil passage 200, oil supply means arranged in an upstream side of the turbocharger 320 in the lubricating oil passage 200 and capable of supplying the lubricating oil circulating in the lubricating oil passage 200 to the turbocharger 320, and a bypass oil passage 330 capable of bypassing the lubricating oil circulating in the lubricating oil passage 200 from the upstream side to the downstream side of the oil supply means. Supply of the lubricating oil to the turbocharger 320 via the bypass oil passage 330 is started when the lubricating oil cannot be supplied to the turbocharger 320 via the oil supply means. |
