An engine oil strainer comprises a lubricating oil passage (1), and an oil inlet (3) and an oil outlet (4) which are respectively disposed at two ends of the lubricating oil passage (1). The engine oil strainer further comprises a check valve (7) 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. The lubricating oil is temporarily stored in the engine oil strainer, which can effectively reduce the time for establishing desired oil pressure when the internal combustion engine resumes operation. The lubricating oil can also reach the proper lubrication position more rapidly. As a result, the internal combustion engine can be sufficiently lubricated as quickly as possible.
