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 lubricant passage way of a diesel engine suitable for solving scuffing of a cylinder bore of an engine and a working method of the lubricant passage way. The lubricant passage way comprises an oil pool, a vertical oil inlet passage arranged in a diesel engine body and connected with the oil pool, a one-way valve arranged at the bottom of the vertical oil inlet passage and preventing engine oil in the vertical oil inlet passage from flowing back to the oil pool, and an engine oil pump communicated with the top of the vertical oil inlet passage. After the engine oil pump halts, the one-way valve seals the engine oil in the vertical oil inlet passage, and the engine oil pump can rapidly pump the engine oil into the lubricant passage way when starting again. The difficult problem that the engine oil is pumped slowly when the engine starts is solved, and the problems of bearing score, scuffing of the cylinder bore of the engine and the like 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...
