Problems solved by technology

The use of internal oil passage lubrication requires the engine crankcase to have sufficient volume to accommodate the lubricating oil capacity specified by engines with different displacements, which will result in a larger engine size, which is not suitable for off-road motorcycles’ requirements for engine volume
At the same time, there are many materials required to make the engine crankcase, and the cost will increase, and the cooling effect of the lubricating oil is not obvious. The cylinder temperature and oil temperature of the engine are high, which is not conducive to the normal operation of the engine and will reduce the power of the engine. It is not suitable for Large displacement air-cooled engine

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0018] Such as figure 1 As shown, engine lubricating oil is routed to crankcase 1, oil filter 2, crankshaft needle roller 3, cylinder block 4, cylinder head 5, main shaft 6, countershaft 7, external oil tank 8, oil pump 9, primary oil filter 10. The first outer oil pipe 11, the second outer pipe 12, the third outer oil pipe 13 and the three-way outer oil pipe 14 are composed, wherein both sides of the crankcase 1 are equipped with crankcase covers, and at the bottom of the crankcase 1 Once an oil filter 10 is installed, an oil filter 2, a crankshaft needle 3, a main shaft 6, an auxiliary shaft 7 and an oil pump 9 are also installed in the inside of the crankcase 1. A cylinder block 4 is arranged on the top of the crankcase 1 , and a cylinder head 5 is installed on the cylinder block 4 . The transmission structure and working principle in the engine are the ...

Abstract

The invention relates to an engine lubricant passage. An oil inlet of a first cavity of an oil pump is communicated with an oil outlet of an once oil filter, an oil outlet of the first cavity of the oil pump is communicated with an oil inlet of an external oil tank, a first oil outlet of the external oil tank is communicated with an oil inlet of a second cavity of the oil pump, a second oil outlet of the external oil tank is communicated with an external oil inlet of a cylinder head, an oil outlet of the second cavity of the oil pump is communicated with an oil inlet of an oil filter, a crankcase cover oil passage communicated with an oil outlet of the oil filter is divided into two passages, one passage is communicated with an oil inlet passage of a crank roller pin, the other passage is connected with an oil inlet of an external three-way oil pipe, a first oil outlet of the external three-way oil pipe is communicated with oil holes of a main shaft and a secondary shaft, and a second oil outlet of the external three-way oil pipe is communicated with a camshaft oil channel. The invention not only achieves the purpose of lubricating an engine, but also can obviously reduce the cylinder temperature and the oil temperature of the engine, improves engine operating conditions and increases engine power.

Description

technical field [0001] The invention belongs to the technical field of engine lubrication, and in particular relates to an engine lubricating oil cooling system on a motorcycle. Background technique [0002] General-purpose motorcycle engines store the lubricating oil for the lubrication and cooling system in the engine crankcase, and the oil pump in the crankcase sends the lubricating oil through the oil passages inside the engine to the crankshaft needle roller → cylinder hole, piston ; cam and rocker arm or rocker arm and push rod of the cylinder head → lower rocker arm and cam; rotating parts of the main and auxiliary shafts; bearings; purpose of the engine. The use of internal oil passage lubrication requires the engine crankcase to have sufficient volume to accommodate the lubricating oil capacity specified by engines of different displacements, which will result in a larger engine volume, which is not suitable for off-road motorcycles for engine volume requirements. ...
