The utility model discloses a check valve in an engine lubrication system. The check valve which only can convey oil to an engine oil pump is arranged in the middle of an oil conveying pipe between an engine oil tank and the engine oil pump of an engine, an oil inlet pipe of the check valve is connected with the engine oil tank, and an oil outlet pipe is connected with the engine oil pump. The check valve has the advantages that: engine oil can be effectively prevented from returning to the engine oil tank, the oil conveying pipe above the check valve always has the engine oil, when the engine is started again, the engine oil pump can quickly convey the engine oil to all parts, a piston, a turbocharger and other engine parts can be prevented from being abraded, and the service life of a machine can be prolonged; and only one check valve is arranged in the conventional engine oil pump, and the check valve has a simple structure, is convenient to refit, and is low in cost.
