An engine pulse air-oil lubrication system comprises a crankcase (2) and a lubrication oil box (1) arranged on the outer side. The lubrication oil box (1) and the crankcase (2) are separated by means of a box wall. More than one blowing-sucking hole (10) is formed in the box wall. The lubrication oil box (1) is communicated with the crankcase (2) through the blowing-sucking hole (10). According to the position of the blowing-sucking hole, when the oil amount in the lubrication oil box (1) is lower than the highest set oil amount, an engine turns freely, and lubrication oil cannot directly flow into the crankcase (2) from the lubrication oil box (1). Also disclosed is a corresponding method, wherein a pulse air flow generated by up-and-down movement of a piston is used to blow generated small lubrication oil particles to parts that need lubrication in sequence, and send a minute amount of lubrication oil that has been used out of the engine. |
