Problems solved by technology

However, increasing the flow rate of the oil pump and increasing the oil pressure of the lubricating oil will cause the engine to have the risk of oil loss due to sudden pipe explosion, which poses a greater threat to the service life of the entire engine

Abstract

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 crankshaft, the outlet of the dark oil passage and the inlet of the main oil passage of the crankshaft are connected in a sealed manner, and the high-pressure oil in the dark oilpassage enters the main oil passage of the crankshaft through the casing. The lubricating system can shorten the lubricating oil passage line, it is not necessary to increase the oil pump flow rate and oil pressure, and the probability of tube burst is reduced.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine lubricating system and an engine. Background technique [0002] In the engine, the lubrication system is a very critical system, and the quality of the lubrication system directly determines the service life of the entire engine. At present, the lubricating oil circuit of the engine mostly adopts the way of external transition, so as to realize the reasonable deployment of the lubricating oil of the whole engine. Among them, the external connection of the lubricating oil circuit is mainly the front design of the organic oil pump and the rear design of the oil pump. When the oil pump is in the front, the lubricating oil line of the crankshaft connecting rod neck is long, and it needs to bypass the body and side cover to introduce the lubricating oil Crankshaft lubricating oil circuit. When the lubricating oil line is long, not only the loss of oil pressure ...
