Embodiment Construction

[0021] 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 lubricating oil way of a diesel engine and a working method thereof. The lubricating oil way comprises an oil pool, a vertical oil inlet channel, a one-way valve and an engine oil pump, wherein the vertical oil inlet channel is arranged in an engine body of the diesel engine and connected with the oil pool, the one-way valve is arranged at the bottom of the vertical oil inlet channel and used for preventing engine oil from flowing back to the oil pool, and the engine oil pump is communicated with the top of the vertical oil inlet channel. After the engine oil pump is shut down, the one-way valve is used for sealing the engine oil in the vertical oil inlet channel. When the engine oil pump is reactivated, the engine oil can be rapidly drawn to a lubricating oil channel by the engine oil pump. The difficulty that the engine oil is slow to feed during the activation of the engine is overcome, and the problems of bearing score and scuffing on the engine are effectively solved.

Description

[0001] This application is a divisional application, the application number of the original application: 2012102229247, the application date: 2012-06-29, the title of the invention: the lubricating oil circuit of the diesel engine and its working method. technical field [0002] 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 [0003] 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 lubrica...
