Description
Technical field
The utility model relates to a kind of Oil-gas Separation air interchanger of Oil-gas Separation air interchanger, particularly a kind of mini four-stroke gasoline engine.
Background technique
Contain organic oil in the waste gas that the mini four-stroke gasoline engine operation process is discharged, common way is that this waste gas that contains organic oil is introduced on the empty filter with pipe, to reduce the pollution of waste gas to environment, this waste gas that contains organic oil enters to mix with fresh air again behind the sky filter and carries out the next round running, this not only causes the machine oil waste, and the sky filter is made moist, the Carburetor mouth blocks, enter problems such as causing burning is bad, carbon distribution, enhance faster wear in the firing chamber, cause gasoline engine performance further to descend.At the problems referred to above, solve at present the petrolic way of mini four-stroke and be in the labyrinth structure mode of designs fix on the crankcase or on cylinder head and realize that respiratory ventilation carries out Oil-gas Separation, this structure has the following disadvantages: the one, and limited by spatial structure during design, structure Design and Calculation is very loaded down with trivial details; The 2nd, Design Theory and actual effect deviation are big, are difficult for adjusting; The 3rd, Oil-gas Separation is thorough not enough, and effect is undesirable, and vent still has the oil droplet ejection, causes body, cleaner cartridge cleaner to pollute, and oil consumption is still high, makes mini four-stroke gasoline engine can't reach American-European countries's emission standard.For this reason, many manufacturers and knowledgeable people develop and develop, but do not have better products to emerge so far as yet.
Summary of the invention
For overcoming the problems referred to above that existing gas and oil separating plant exists, the purpose of this utility model provides the mini four-stroke gasoline engine Oil-gas Separation air interchanger of a kind of simple and reasonable, good oil gas separation effect, long service life, reliable operation.
The technological scheme that its technical problem that solves the utility model adopts, it comprises crankcase body, bent axle, be installed in the crankshaft gear on the bent axle, be provided with running shaft in the described crankcase body, running shaft gear with the crankshaft gear engagement is housed on the running shaft, running shaft is provided with spoke, one side of running shaft is provided with center hole, at least be provided with an inlet hole that communicates with this center hole on the spoke, crankcase body is provided with attachment hole, the end of running shaft is installed in this attachment hole after sealing by Sealing, crankcase body is provided with air outlet hole, and an end of air outlet hole communicates with center hole by attachment hole.
The other end of described air outlet hole links to each other with empty filter or secondary oil air separation.
After adopting said structure, following advantage and effect are arranged compared with prior art: the one, this device design makes to make full use of the casing remaining space in crankcase body; The 2nd, can be used as the breathing equipment independent utility of petrol engine, the auxiliary device that also can be used as the petrol engine breathing equipment is used; The 3rd, after petrol engine increased this device, Oil-gas Separation was thorough, did not pollute body and cleaner cartridge cleaner, and the machine oil of separation directly is back in the crankcase body, can reduce consumption of lubricating oil, and gasoline exhaust reaches American-European countries's standard.The 4th, this apparatus structure is simple, reliable operation, easy to process.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Figure 1, specific embodiments for a kind of mini four-stroke gasoline engine Oil-gas Separation of the utility model air interchanger, it comprises crankcase body 1, bent axle 9, be installed in the crankshaft gear 10 on the bent axle 9, be provided with running shaft 2 in the described crankcase body 1, be equipped with on the running shaft 2 with, running shaft 2 is provided with spoke 3, one side of running shaft 2 is provided with center hole 5, at least be provided with an inlet hole 4 that communicates with this center hole 5 on the spoke 3, crankcase body 1 is provided with attachment hole 6, the end of running shaft 2 is installed in this attachment hole 6 after sealing by Sealing 8, crankcase body 1 is provided with air outlet hole 7, one end of air outlet hole 7 communicates with center hole 5 by attachment hole 6, and the other end of air outlet hole 7 links to each other with empty filter or secondary oil air separation.Mini four-stroke gasoline engine bent axle 9 in the course of the work meshes rotary driving axles 2 by crankshaft gear 10 and running shaft gear 11, inlet hole 4, center hole 5, attachment hole 6 and air outlet hole 7 are formed the respiratory ventilation passage of petrol engine, oil-containing gases is the separation of condensing of the hole arm of oil gas in center hole 5 during by this passage, machine oil gets rid of in the crankcase body 1 by running shaft 2 centrifugal force, gas back is again discharged by air outlet hole 7, and this is simple and reasonable, good oil gas separation effect, reliability height.
Claims (2)
1, a kind of mini four-stroke gasoline engine Oil-gas Separation air interchanger, comprise crankcase body (1), bent axle (9), be installed in the crankshaft gear (10) on the bent axle (9), it is characterized in that: be provided with running shaft (2) in the described crankcase body (1), running shaft gear (11) with crankshaft gear (10) engagement is housed on the running shaft (2), running shaft (2) is provided with spoke (3), one side of running shaft (2) is provided with center hole (5), at least be provided with an inlet hole (4) that communicates with this center hole (5) on the spoke (3), crankcase body (1) is provided with attachment hole (6), the end of running shaft (2) is installed in this attachment hole (6) after sealing by Sealing (8), crankcase body (1) is provided with air outlet hole (7), and an end of air outlet hole (7) communicates with center hole (5) by attachment hole (6).
