Beschreibung
Zusammenfassung:	The invention belongs to the field of engines, and discloses an engine lubrication system and an engine. According to a method, a crankcase, a side cover and a bridge connection mechanism are included, a crankshaft is arranged in the crankcase, and a main oil passage of the crankshaft is arranged in the crankshaft; the side cover is arranged on one side of the crankcase, and a dark oil passage isarranged in the side cover; the bridge connection mechanism includes a casing and a sealing portion, the sealing portion is fixedly arranged on the outer side wall of the casing, one end of the casingis inserted into an outlet of the dark oil passage, and the sealing portion is located on the outer side of the outlet of the dark oil passage; and when the engine works, the casing moves towards aninlet of the main oil passage of the crankshaft under the pressure effect of the high pressure oil in the dark oil passage, so that the sealing portion is pressed against the inlet end face of the main oil passage of the cranks
