Detailed description of the invention
With reference to figure 1, the crankcase ventilation system in the present embodiment mainly comprises gs-oil separator 100, protectsCover body 200 and cover plate 300 3 parts. Together with wherein guard shield body 200 fastens to cover plate 300Form engine cylinder cover guard shield, the concrete internal structure of engine cylinder cover guard shield will be described below.One-body molded on guard shield body 200 have a gs-oil separator nest seat 210, and gs-oil separator 100 is pacifiedBe contained in gs-oil separator nest seat 210, that is to say, shell 110 parts of gs-oil separator 100Or be positioned at gs-oil separator nest seat 210 inside completely, and escape pipe 120 is exposed to outside.
In ensuing description, taking towards a side of engine cylinder cover, cylinder body as in, send out to deviate fromOutside one side of motivation cylinder cap, cylinder body is.
With reference to figure 4, except gs-oil separator nest seat 210, guard shield body 200 also has guard shield bodyDiapire 230 and around the guard shield body sidewall 240 of guard shield body diapire 230, is buckled in cylinder thereby formThe inner space of the side of covering.
In conjunction with Fig. 2, Fig. 3, Fig. 4, cover plate 300 is arranged on the inside of guard shield body 200, from Fig. 3More high-visible, interval between cover plate 300 and the diapire 230 of guard shield body 200, thereby form asThe oil gas pre-separation space 250 of the relative closure shown in Fig. 4, and oil gas pre-separation space 250 isThe space of a relative closure, only at the first air inlet 220, the second air inlet 214, oil return opening 310Place is communicated with oil gas pre-separation space 250 is outside. In conjunction with Fig. 2 and Fig. 3, as seen shown in Fig. 2The high order end position of cover plate 300, reserved the first air inlet between guard shield body 200 and cover plate 300220, oil gas pre-separation space 250 is communicated with crankcase. As seen from Figure 4, in oil gas pre-separationIn space 250, be provided with stacked oil baffle 260, interlaced dividing plate 270, and in conjunction with figure6 is visible, fastens to behind guard shield body 200 inside the restricting orifice on cover plate 300 at cover plate 300320 also can extend in oil gas pre-separation space 250.
With reference to figure 7, in this figure, specifically illustrate the stacked structure of multilayer oil baffle 260. In conjunction with Fig. 7In the description of carrying out, easy and clear for what describe, "up" and "down" only refers to diagram sideTo, do not represent the "up" and "down" in the assembly direction of engine, meanwhile, with from initiating terminal261 directions of pointing to end 266 are vertical direction. Gas in engine crankcase is byOne air inlet 220 enters oil gas pre-separation space 250, then enters between each layer of oil baffle 260Gas passage. Each oil baffle 260 all has the first extension 262, the second extension 264,Three extensions 265 and the 4th extension 267. Wherein, the first extension 262 is from oil baffle 260Initiating terminal 261 starts upwards and extends back, the first extension 262 end at oil baffle 260 inEnd 263, that is to say, middle-end 263 is also the end of the first extension 262 simultaneously. Second extendsPortion 264 starts upwards also at the end (being the middle-end 263 of oil baffle 260) of the first extension 262Extend towards initiating terminal 261 directions. The 3rd extension 265 at the end of the first extension 262 (The middle-end 263 of oil baffle 260) start downwards and continue to extend back, the 3rd extension ends at gearThe end 266 of oiled-plate method 260. Like this, see on the whole the first extension 262, the second extension264 and the 3rd extension 265 formed roughly " entering " word shape. Oil baffle 260 also has the 4thExtension 267, the four extensions 267 (are oil baffle 260 from the end of the 3rd extension 265End 266) start downwards and extend towards initiating terminal 261 directions. The initiating terminal 261 of oil baffle 260Expand and form drum-like shape, make the upper and lower end face of initiating terminal 261 all exceed the first extension 262Upper and lower surface. Crank case gases enters the each layer of gas between oil baffle 260 from the first air inlet 220In path process, first gas run into initiating terminal 261, shunted at this gas, and due to cydariformEffect and reduced pneumatic noise. Subsequently, gas flows along direction shown in the band arrow solid line in figure,Flow direction starts to become curve, and gas is blocked after running into the second extension 264, and larger oil droplet is dividedFrom being attached on the surface of the first extension 262 and the second extension 264, then under Action of Gravity FieldDrop onto on cover plate 300, then flow back into engine interior from refluxing opening 310. Meanwhile, due to gasBody and the second extension 264 collisions can cause a part of gas backstreaming, as the band arrow dotted line institute in figureShow, this portion gas can run into the stopping of initiating terminal 261 of cydariform, make larger oil droplet fully assemble andDrop. After the second extension 264, gas continues along upper and lower two-layer the 3rd extension 265Between channel flow, run into after the stopping of the 4th extension 267 of upper strata oil baffle 260 gasInterior oil droplet is continued to be separated, and is gathered in the surface of the 3rd extension 265 and the 4th extension 267,Then under Action of Gravity Field, fall on cover plate 300. As seen from the figure, represent horizontal line with dotted line,The top of the second extension 264 of lower floor's oil baffle 260 will be higher than the 4th of upper strata oil baffle 260The bottom of extension 267, like this, all gas of the passage between two-layer oil baffle 260 of flowing through,Or be subject to stopping of the second extension 264 and carry out Oil-gas Separation, or be subject to the 4th extension 267Stop and carry out Oil-gas Separation, the larger oil droplet in all gas all can be separated substantially,Thereby improve oil gas pre-separation effect.
Although in the foregoing description to " on ", the concept of D score carried out specific explanations, particularly,Oil baffle 260 is to be attached on diapire 230, but those skilled in the art should imagine, stackedOil baffle 260 can also be attached on sidewall 240, now in oil baffle 260 structures " on ",D score direction is consistent with the assembly direction of cylinder block, cylinder head, cylinder cap guard shield, and this still belongs to powerThe category of the "up" and "down" during profit requires. But, when oil baffle 260 is attached at sidewall 240When upper, the oil droplet of assembling on upper strata oil baffle 260 can drop on lower floor's oil baffle 260 but not dropTo cover plate 300, thereby causing the gas passage trapped fuel between oil baffle 260, is not therefore excellentChoosing.
In conjunction with Fig. 4 and Fig. 6, gas is leaving after stacked oil baffle 260, continues to flow through handing overWrong dividing plate 270 and restricting orifice 320, carry out further at dividing plate 270 places and throttle orifice 321 placesOil gas pre-separation. Subsequently, the gas in oil gas pre-separation space 250 is by the second air inlet 214Directly enter oil gas pre-separation nest seat 210. As seen from Figure 4, gs-oil separator nest seat 210 parts are protrudingTo guard shield body interior, the protruding outside to guard shield body of part. At gs-oil separator nest seat diapire 212Upper, be provided with check valve 213, check valve 213 only allows the fluid stream in gs-oil separator nest seat 210To engine interior, and do not allow to flow in the other direction.
With reference to figure 5, visible the second air inlet 214 is arranged on gs-oil separator nest seat sidewall 211.
In conjunction with Fig. 1 and Fig. 5, gs-oil separator 100 be installed to gs-oil separator nest seat 210 interior after,Between the sidewall 211 of gs-oil separator shell 110 and gs-oil separator nest seat, there is gap, i.e. oil gasThe internal diameter of separator nest seat 210 is greater than the external diameter of gs-oil separator shell 110. And, preferred oilThe air inlet of gas separating device 100 is positioned at its bottom. Like this, at the crankcase ventilation system of the present embodimentIn, crank case gases is after a series of oil gas pre-separations in oil gas pre-separation space 250, fromTwo air inlets 214 directly enter in gs-oil separator nest seat 210, and at gs-oil separator nest seat 210And flow in the gap between gs-oil separator 100. First, gs-oil separator 100 and guard shield bodyBetween 200, no longer need flexible pipe to connect, avoid freezing in flexible pipe; Secondly,, when winter, rely on oil gasThe cold service of separator nest seat 210 projections, gs-oil separator nest seat 210 and gs-oil separatorGas temperature mobile in gap between 100 is lowered, and the interior remaining little oil droplet of gas at low temperaturesEasily liquefaction flows to diapire 212 along the sidewall 211 of gs-oil separator nest seat 210 under Action of Gravity Field,And be back to engine interior via check valve 213. And because the freezing point of steam will be higher than fluid,Therefore steam can condense on the sidewall 211 of gs-oil separator nest seat 210, and in other words, oil gas dividesUtilize low temperature to realize further from the gap between device nest seat 210 and gs-oil separator shell 110Oil gas pre-separation and except steam effect, and compared with flexible pipe, to gs-oil separator nest seat 210 inwallsDeicing obviously simpler, and because the diameter of gs-oil separator nest seat 210 will be much larger than oftenWith flexible pipe, therefore freezing, it is little that gas communication is hindered. That is to say, it is low that the utility model has been avoidedTemperate zone come adverse effect time, utilize low temperature to produce oil gas separation. And gs-oil separator100 air inlet is arranged on the bottom of gs-oil separator 100, and like this, gas is from gs-oil separator nestAfter the second air inlet 214 on the sidewall 211 of seat enters, interior mobile at gs-oil separator nest seat 210Distance and time are lengthened out, and then enter gs-oil separator 100 inside, and this is beneficial to oil gas pre-separationMore abundant.
Although the present invention is described in conjunction with above embodiment, the present invention is not defined toState embodiment, those of ordinary skill in the art can easily modify to it and change, but notLeave essence design of the present invention and scope.
