Embodiment
As shown in Figure 1 to Figure 3, a kind of engine impulse oil gas lubricating system, comprise crankcase 2 and at the lubricating oil tank 1 of crankcase arranged outside, described lubricating oil tank 1 arranges more than one pressure-vaccum hole 10 and is communicated with crankcase 2 inner chambers on the tank wall adjacent with crankcase 2, the pulsing airflow that it utilizes piston up-down to produce, blow, inhale the lubricant oil in lubricating oil tank 1, by the little elaioleucite of the lubricant oil of generation sequentially blow to each need to be lubricated part.
Wherein, the position in pressure-vaccum hole 10 arrange and with lubricating oil tank 1 in oil mass setting while making motor arbitrary overturn lubricant oil all can not flow to crankcase from lubricating oil tank.Concrete, in the present embodiment, described lubricating oil tank takes the shape of the letter U and surrounds bottom surface and the width bi-side of crankcase.Described pressure-vaccum hole is provided with three, lay respectively at lubricating oil tank bottom centre and central position, width two side, and oil mass in lubricating oil tank, at motor during in level, the pressure-vaccum hole of described lubricating oil tank bottom centre is positioned in the 50mm height of lubricant oil liquid level top.As shown in Fig. 4 to Fig. 8, no matter how motor overturns, and due to the rationality of pressure-vaccum hole site setting, and in lubricating oil tank, oil mass is suitable, and lubricant oil all can directly not flow to crankcase from lubricating oil tank.The mouth area sum in described pressure-vaccum hole is less than 1 with the ratio of cylinder sectional area.
Piston up-down makes the pulsing airflow of crankcase 2 interior generations remove to blow, inhale the lubricant oil in lubricating oil tank 1 by pressure-vaccum hole 10, lubricant oil has been swung, a small amount of oil droplet is splashed into crankcase 2 from pressure-vaccum hole, crank by High Rotation Speed takes up whipping, make it into little elaioleucite, the air-flow that these little elaioleucites are pressed down blows to 6-cylinder head cover, 7-Oil-gas Separation chamber, 5-valve rocker chamber, cam chamber 4-push rod duct, 8-breathing pipe 9 from crankcase successively by crankshaft bearing 3, in this process, little elaioleucite is lubricated with cooling the part of process.Meanwhile, crankshaft-link rod and cylinder wall and piston have been lubricated.
In the utility model, the setting in pressure-vaccum hole and to utilize pulse pressure-vaccum lubricant oil that piston up-down makes to produce in crankcase to be lubricated be core; All the other participate in lubricated part, crankshaft bearing, cam chamber, push rod duct, valve rocker chamber, cylinder head cover, Oil-gas Separation chamber and breathing pipe are the indispensable mechanism components of all four stroke engine, and the utility model is to utilize itself position to arrange and existing structure makes it lubricated or participate in lubricated.
The pulsing airflow producing due to piston up-down blows, inhales with the high frequency of 0.01-0.002 second, it is far that little elaioleucite can once not walked, first can be attached on chamber wall and part more nearby, it is far that little elaioleucite can once not walked, first can be attached on chamber wall more nearby and part and form oil film, then need to lubricate and cooling component along with each lower pressure gas stream blows to each successively gradually by it.By adopting transparent pipe to monitor, described oil film is very slow speed and advances.
At lower pressure gas stream, blowing in the process that lubricant film goes ahead, because variation is blown, inhaled to the pulsing airflow high frequency that piston up-down produces, in addition the very little breathing pipe specific frictional resistance in cross section is very large, make the malleation absolute value in machine always be greater than negative pressure absolute value, so, although lubricant film is walked, stop, general trend is slowly to crawl towards outlet.By adopting transparent pipe monitor and detection, the gait of march of oil film is 2-5mm/s.
In the process of film lubrication part, the oil body of bringing into play effect can decline, lower than the oil body of not bringing into play effect, the former is being blown the speed of advancing by air-flow and will, faster than the latter, finally from breathing pipe, enter airborne gas and only have minute quantity to bring into play the lubricant oil that effect is emulsion form.
Pulse oil-air lubrication method in the present invention, lubricant oil is unidirectionally to advance lubricatedly, the lubricant oil of bringing into play effect no longer returns to lubricating oil tank, is conducive to keep the pure and greasy property of the quality of lubricant oil of the effect of not bringing into play.
By the position and size in the pressure-vaccum hole on controlling test lubricating oil tank tank wall adjacent with crankcase, can control impuls stream pressure and elaioleucite production, also just controlled the velocity of discharge of pressure and the emulsion form lubricant oil of breathing pipe Exhaust Gas, thereby guarantee under lubricated sufficient prerequisite, the lubricant oil of not bringing into play effect completely can not be discharged from outside machine, reach reduction lubrication oil consumption, reduced the object of polluting.
The present invention proposes a kind of new four stroke engine pulse oil-air lubrication method, it is different from all before this four stroke engine " fuel feeding, oil return circulating oil system " technical know-how and modular construction design.With simple method extremely, solved the difficult problem that this technical field exists.It does not need the one-way valve in design before, rotary valve, stir spindle, oil supply gallery, drainback passage, return tube, hollow crankshaft etc. is the lubricated component that arrange, on the tank wall of being only separated by lubricating oil tank and crankcase, one or more pressure-vaccum hole is set, the pulsing airflow that utilizes piston up-down to produce, by the lubricating oil oil film of generation sequentially blow to each need to be lubricated part, and minute quantity was brought into play to the lubricant oil acting on and sent outside machine, realized and " fuel feeding, oil return circulating oil system " the different pulse oil-air lubrication method of traditional theory thinking.
