Embodiment Construction

[0020] See Figures 1 to 6 , the lubricating oil path of the diesel engine of the present embodiment comprises: an oil sump, a vertical oil inlet passage connected to the oil sump arranged in the diesel engine block, and a machine oil in the vertical oil inlet passage prevented from entering the vertical oil passage at the bottom of the vertical oil inlet passage. The one-way valve 2 that returns to the oil pool, the coarse filter 1 (the coarse filter 1 is a fine mesh plate) located at the bottom of the one-way valve 2, and the machine connected to the top of the vertical oil inlet. oil pump 3. A one-way valve 2 is arranged between the oil pump 3 and the oil pool, which can prevent all the oil in the vertical oil inlet passage from flowing back into the oil pool after the machine stops, that is, after the machine is stopped, the machine oil is sealed in the oil pool by using the one-way valve. The above vertical oil inlet passage, when restarting, the oil pump can quickly pum...

Abstract

The invention relates to a lubricant oil passage of a diesel engine and a working method of the lubricant oil passage. The lubricant oil passage comprises an oil bath, a vertical lubricant oil feeding passage, a one-way valve and an engine oil pump, wherein the vertical lubricant oil feeding passage is arranged inside a diesel engine body and is connected with the oil bath; the one-way valve is arranged at the bottom of the vertical lubricant oil feeding passage and is used for preventing the engine oil in the vertical lubricant oil feeding passage from flowing back to the oil bath; and the engine oil pump is communicated with the top part of the vertical lubricant oil feeding passage. By arranging the one-way valve between the engine oil pimp and the oil bath, the engine oil in the vertical lubricant oil feeding passage is prevented from flowing back to the oil bath completely when the engine is stopped, i.e., the engine oil is completely sealed in the vertical lubricant oil feeding passage by using the one-way valve after the engine is stopped; when the engine is started again, the engine oil can be pumped into the lubricant oil passage by the engine oil pump rapidly. The difficult problem that the engine oil is fed slowly when the engine is started is solved; and the problems of bearing score, scuffing of cylinder bore and the like of engines are solved effectively.

Description

technical field [0001] The invention relates to a lubricating oil circuit of a diesel engine used for engine oil backflow prevention and a working method thereof. Background technique [0002] Engine lubrication is generally divided into two types: oil throwing lubrication and forced pressure lubrication. Oil throwing lubrication uses the oil throwing plate to throw the splashed oil in the crankcase to the lubricating oil passage. Its characteristic is that as long as the engine is running, the oil will be thrown out. The work is reliable, but the lubrication pressure is small, so it is generally only used on ultra-small engines. Most engines use forced pressure lubrication, that is, an oil pump is installed in the lubricating oil circuit, and the oil pump sucks the oil out from the oil pan and then presses it to the various lubricating oil circuits of the engine. This kind of oil with a certain pressure can Ensure that all friction pairs are fully lubricated. But the disa...
