Description
Technical field
The present invention relates to a kind of lubricant oil valve arrangement of the lubricated oil gas circulation that realizes motor and the motor of this lubricant oil valve arrangement of a kind of application.
Background technique
At present common four stroke engine all is to add lubricant oil by lubrication system independently toward engine interior, solves thus the friction problem of engine interior moving element.But adopt the motor of this lubrication system architecture owing to need to increase extra lubricant oil transporting system, therefore cost is high, and burn oil, job insecurity, the problem such as flame-out when motor overturns, occur easily, so generally be to be applied in that the engine locations such as automobile, motorcycle do not overturn, relatively-stationary place.
The at present general circulation of adopting following 3 kinds of schemes to realize lubricated oil gas of existing turning four stroke engine: 1) piston movement opens and closes gas port; 2) one-way valve control migration of oil and gas line direction; 3) adopt crank control gas port to open and close.But all there is certain deficiency in these schemes.
1) piston opens and closes the gas port scheme: because inertia and the engine speed of oil gas are usually all very high, need to early open morning for the running efficiency maximization that guarantees oil gas closes, the relative top dead center of crank angle during the opening and closing of the gas port of this scheme is symmetrical, can't accomplish early to open and early close.The height of piston need to strengthen preferably as far as possible and can greater than piston stroke, cause piston weight increasing, cylinder body to add the problems such as high simultaneously;
2) one-way valve scheme: one-way valve is by acting on opened by pressure on the valve, need pressure to arrive to a certain degree and just open, engine speed is usually all very high, because the inertia of one-way valve, the quick variation that its switching is difficult to catch up with pressure causes to open late late closes, and has anti-stream unavoidably;
3) crank control gas port opens and closes scheme: this scheme can be utilized the dissymmetrical structure of crank to realize opening the morning of gas port and close morning.But exist on the one hand the large cost of crank weight high, be difficult to realize the problem of best crankshaft vibration design.Crank bears very large piston inertia power when running up on the other hand unavoidably distortion, so the opening of crank and lubricated gas channel must keep rational gap, also can not there be the problems such as anti-stream in its opening by tight closing.

Described cam chamber spill port 1 is communicated with passage 23 bottoms, and the diameter of cam chamber spill port 1 is less usually, has throttling action; When motor was just put work, the liquid lubricant oil that passage 23 and valve cage 15 gather was pumped into A channel 3 from cam chamber spill port 1.
Described crankcase spill port 2 is arranged on crankcase bottom, and the diameter of crankcase spill port 2 is less usually, has throttling action; When motor was just put work, the liquid lubricant oil of crankcase inner accumulated was pumped into A channel 3 from crankcase spill port 2.
Cylinder head cover at motor arranges oil gas separator, this oil gas separator mainly is made of spill port 19 and free vent 21 under spill port 18, the mist of oil separation chamber in the mist of oil separation chamber 20 of labyrinth structure, the mist of oil separation chamber, and free vent 21 is communicated with air filter through joint; Atomized lubrication oil accumulates on the wall through mist of oil separation chamber 20 time, and when motor was just put work, the liquid lubricant oil that gathers spill port 19 under the mist of oil separation chamber was pumped into B passage 13; When motor inversion work, the liquid lubricant oil that gathers spill port 18 from the mist of oil separation chamber is pumped into B passage 13, accumulate in valve cage 15 and the passage 23 liquid lubricant oil also from the mist of oil separation chamber spill port 18 be pumped into B passage 13; Unnecessary a small amount of atomized lubrication oil enters air filter by free vent 21.
In one end of described B passage 13 and the mist of oil separation chamber under spill port 18 and the mist of oil separation chamber spill port 19 be communicated with, the other end is communicated with oil mist chamber return tube 6 by A channel 3.
The cyclic process of the motor atomized lubrication oil of this case is (being that two strokes of motor are as a circulation) take one week of crankshaft rotating as a circulation, and the specific works process is as follows:
Such as Figure 47, Figure 48, shown in Figure 49, when piston 14 was up, the common spatial volume that forms of lower cavity volume and crankcase increased, and gas pressure reduces; Oil drainage hole 27 on the oil extraction this moment rotary valve 25 is not communicated with oil drain passage 24, and the oil inlet hole 26 on the oil-feed rotary valve 9 is communicated with oil inlet passage 10, lubricant mist in the oil mist chamber 4 is pumped in the crankcase through oil mist chamber oil outlet tube 8 and oil inlet passage 10, the pressure decreased in the oil mist chamber 4.
Shown in Figure 50, Figure 51, Figure 52, in the time of near piston 14 runs to top dead center, the oil drainage hole 27 on the oil extraction rotary valve 25 is not communicated with oil drain passage 24, and the oil inlet hole on the oil-feed rotary valve 9 26 is not communicated with oil inlet passage 10.
Shown in Figure 53, Figure 54, Figure 55, when piston 14 is descending, (may also may be the expansion stroke of motor for the aspirating stroke of motor, the diagram valve is opened, be aspirating stroke), the common spatial volume that forms of lower cavity volume and crankcase reduces, and gas pressure raises; Oil inlet hole 26 on the oil-feed this moment rotary valve 9 is not communicated with oil inlet passage 10, and the oil drainage hole 27 on the oil extraction rotary valve 25 is communicated with oil drain passage 24, and lubricant mist enters valve cage 15 through oil drain passage 24, passage 23, and the pressure in the valve cage 15 raises.
Shown in Figure 56, Figure 57 and Figure 58, in the time of near piston 14 runs to lower dead center, the oil drainage hole 27 on the oil extraction rotary valve 25 is not communicated with oil drain passage 24, and the oil inlet hole on the oil-feed rotary valve 9 26 is not communicated with oil inlet passage 10.
When piston 14 is again up, then repeat said process.
The cyclic process of the motor atomized lubrication oil of this case as shown in figure 46, the pressure P 4 of mist of oil separated type 20 is near atmospheric pressure P0, because the continuous suction of crankcase and pumping, the pressure P 1 of oil mist chamber 4 is less than the pressure P 4 of mist of oil separation chamber 20, the pressure P 3 of valve cage 15 greater than the pressure P 4 of mist of oil separation chamber 20 namely:
P4≈P0
P3>P4>P1
P3>P0>P1
Because there is negative pressure in oil mist chamber 4, all gas or liquid lubricant oil in B passage 13 all can be sucked oil-feed fog chamber 4.
The above only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
