Description
Technical field
The present invention relates to a kind of internal combustion engine drive technology field, the more particularly to a kind of oscillating tooth high-efficiency lubricating of push rod five transmission
Two juxtaposed cylinders internal combustion engine.
Background technology
Current conventional piston internal combustion engine is more, and using cylinder as power unit, piston is connected by piston pin, connecting rod with bent axle,
Using crank connecting link as transmission device, connecting rod is connected with flywheel, and piston is reciprocating in cylinder, promotes bent axle to turn by connecting rod
It is dynamic；In order to which inspiration live gas and discharge waste gas are provided with inlet valve and exhaust valve, piston is lifted off crankshaft center farthest and deserved to be called only
Point, piston is lifted off crankshaft center and most nearby claims lower dead center.Do work and realize by the expansive force that mixed oil and gas burning is produced in cylinder
Only one of which is rushed in air-intake of combustion engine, compression, four strokes of expansion work and exhaust, four piston strokes of quartastroke engine
Journey is externally done work in expansion work stroke throw crank linkage, and its excess-three stroke has flywheel to drive completion, Gu Sichong
Journey I. C. engine crankshaft, which often revolves to take two turns, can only do work once.Therefore quartastroke engine crankshaft connecting rod system has the disadvantage that：
1st, because internal combustion engine is that the reciprocating motion of piston is changed into circular motion using connecting bar and crankshaft, when cylinder compression end of stroke
I.e. in the top dead centre of expansion work stroke, mixture combustion causes in-cylinder pressure maximum and produces most strong thrust in cylinder, but this
When toggle in bent axle and connecting rod in straight line be that the arm of force is zero, that is, now no power output is pair at all
Do not do work outside；The connecting rod variable angle being connected again caused by bent axle is circled necessarily with bent axle, power decentralized is more, can only portion
Divide outflow power, therefore crankshaft connecting rod system make it that the heat utilization rate of internal combustion engine is very low；2nd, connecting rod and piston movement direction are present
Angle piston and the inwall of cylinder block can be caused to produce certain frictional force, the angle that connecting rod exists with piston movement direction is got over
It is big then frictional force is bigger, it is uneven to the frictional force produced by cylinder wall when piston is run in cylinder, so piston exists
The generation of eccentric wear phenomenon is easily caused in cylinder after long-term high-speed motion, cylinder inner wall or piston is damaged and gas leakage, so that internal combustion
The heat utilization rate of machine declines, this problem never solved since being crankshaft-link rod internal combustion engine use.
In addition, performed relative motion during current crankshaft-link rod internal combustion engine between internal combustion engines part with very high speed,
Such as the not only increase internal combustion engine operation of the friction between crankshaft journal and rod journal, camshaft journal and bearing metal surface
Heat produced by power consumption, and friction is also possible to make some working part surface meltings and makes some parts of internal combustion engine
Working surface weares and teares rapidly, so as to cause internal combustion engine not run well.Therefore it is guarantee internal combustion function long-term work, it is necessary to right
Relative movement part surface is lubricated in internal combustion engine, that is, covers one layer of lubricating oil in each part friction surface so that interior
One layer of thin oil film covered between combustion engine parts metals surface power attenuation is reduced to reduce frictional resistance, mitigated and wear and tear and prolong
Long internal combustion engine service life.But the basic task currently as IC engine lubricating oil conveying device is by cleaning, with one
Constant-pressure, proper temperature lubricating oil be continuing to supply the friction surface of moving parts so that internal combustion engine can normal work, because
There must be the lubricating oil pump that enough oil pressure are provided in this IC engine lubricating oil conveying device, but be used in crankshaft-link rod internal combustion engine
Lubricating oil pump then there are problems that so again：1st, lubricating oil pump to take certain space in internal combustion engine domestic demand as a part and
The volume of internal combustion engine is caused to increase, lubricating oil pump is necessarily required to consume certain energy as an independent running gear；2nd, by
Lubricating oil needs are caused just to can guarantee that bent axle obtains preferable lubrication protection under stronger pressure in the complicated structure of bent axle, so
And generally existing pressure is small and be easily caused bent axle tile kilning or locking phenomenon and occur in use for lubricating oil pump, so that interior
Combustion engine quick abrasion is so that short life；3rd, the cost of lubricating oil pump is higher, and the system of internal combustion engine is caused as the necessary part of internal combustion engine
Make added cost.
