Problems solved by technology

When the engine is running at high speed, it is better to have more engine oil flushing the heat engine part of the engine to take away the heat and reduce the heat load of the engine. Less than more oil, resulting in a greater thermal load on the engine

Abstract

The invention discloses an engine and an oil duct structure with adjustable engine oil allocation quantity. The oil duct structure comprises a first oil duct, a second oil duct in butt joint with thefirst oil duct, and an oil-limiting plug; the oil-limiting plug can be automatically reset between the first oil duct and the second oil duct, and a free end of the oil-limiting plug is arranged towards an oil outlet direction of the first oil duct; an oil-limiting channel is formed in the oil-limiting plug; an oil inlet of the oil-limiting channel is arranged at the free end of the oil-limiting plug, and is communicated with the first oil duct; and the oil outlet of the oil-limiting channel is communicated with the second oil duct. The oil duct structure can increase the oil mass supply by using the movement of the oil-limiting plug when the oil pressure is increased to a certain degree, thereby improving the lubricating effect and cooling effect at a specific part; the engine adopts theoil duct structure, and can reduce the abrasion of each movement part in high-speed; the cooling effect is improved, the heat load is lowered, and the service life of the engine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of engine oil distribution, in particular to an engine and an oil channel structure with adjustable oil distribution. Background technique [0002] At present, the engine oil mainly plays two functions of lubrication and cooling in the engine. The oil is generally supplied to various parts that need lubrication and cooling through the oil pump and the corresponding oil passage. [0003] Engine lubrication is divided into two parts: shaft system lubrication (engine body) of crankshaft, main and auxiliary shaft gears and other components, and gas distribution system lubrication (engine head) of camshaft, rocker arm, valve and other components. These two parts are traditional In technology, it is generally allocated according to 25% and 75%. As the engine speed increases, the demand for lubrication of the shaft system changes little, while the demand for lubrication of the valve system changes greatly. The de...
