  • Internal combustion engine, lubrication system, and engine oil strainer
    Patent number: 10876439
    Abstract: An engine oil strainer includes a lubricating oil passage, and an oil inlet and an oil outlet which are respectively disposed at two ends of the lubricating oil passage. The engine oil strainer further includes a check valve which is disposed at the oil inlet and which only allows a lubricating oil to flow into the lubricating oil passage. Also disclosed herein are a lubrication system employing the engine oil strainer, and an internal combustion engine having the lubrication system. When the internal combustion engine stops operating, the lubricating oil flows back from the oil outlet into the engine oil strainer. Since the check valve is disposed at the location of the oil inlet of the engine oil strainer, the lubricating oil flowing back into the engine oil strainer is not capable of proceeding to flow back from the oil inlet into the oil pan.
