Description

Technical Field

[0001] The utility model relates to the field of lubrication of vertical shaft series diesel engines, in particular to a lubrication structure and an engine for vertical shaft diesel engines. Background Art

[0002] In the field of diesel engines, the engine lubrication methods are mainly divided into two types: splashing and pressure splashing. The splashing type is mainly equipped with an oil-slinging needle on the connecting rod assembly. When the crankshaft connecting rod rotates, the oil in the oil pan is thrown out by the rotating centrifugal force and splashed onto various moving parts and the casing wall for lubrication and cooling. The pressure splashing mainly relies on the pressure generated by the oil pump to force the oil to be transported to various moving connections, and then the oil splashed through the fitting clearance lubricates the cylinder liner and piston, and cools the surrounding temperature of the casing cavity.

[0003] At present, the lubrication structure for vertical shaft diesel engines basically adopts splashing type because there is no extra place to install the oil pump. However, the splashing type in vertical shaft diesel engines has the following problems: 1. The splashing type lubrication structure is not easy to control the amount of oil during lubrication. When the amount of oil is too much and the speed is too high, it will lead to too much oil in the cylinder, causing oil burning, overspeed, excessive carbon deposits, and reduced engine life. When the amount of oil is too little or the speed is low, it will cause poor lubrication of the cylinder liner and various connecting motion mechanisms, causing engine damage; 2. Compared with the pressure splashing type, the splashing type consumes more oil, but the effect is not as good as the pressure splashing type. Utility Model Content
