Description
[technical field]
The utility model relates to deaerator, and in particular, the utility model relates to a kind of deaerator that is applied to the hot type of Vehicle Turbocharged petrol engine.
[background technique]
In motor car engine, the lubricant oil that engine cylinder covers can directly be back in the crankcase by the cylinder body spill port.And,, make that the waste gas in the crankcase also can be passed into cylinder cap along spill port because the cylinder body spill port communicates with vent usually.If the pressure in the crankcase is bigger, the lubricant oil that flows back to along spill port can be brought back in the cylinder head cover by waste gas, makes a large amount of gas mixture of generation in housing.These gas mixtures should directly not be drained in the air, because this can cause the continuous minimizing of crankcase inner engine oil, and have a large amount of dusty gass in these gas mixtures, can cause the severe contamination of environment.
Just so; deaerator can be arranged in the crankcase of vehicle usually; its effect is that the oil gas in the crankcase is separated; wherein usually gas separated steam is imported to intake manifold; thereby in cylinder, burn to avoid pollution to environment; the liquid lubricant oil that separates is back to crankcase, to reduce the loss of machine oil.
But when ambient temperature is low, for example work as ambient temperature below zero degrees celsius, lubricating oil temperature is spent low, and moisture condenses in part inside such as deaerators easily, makes lubricant oil produce emulsification, has destroyed the usability of lubricant oil.In addition, if the excess moisture of deaerator inside, this may cause freezing, thereby has stopped up the Oil-gas Separation passage, and crankcase pressure is raise, and can produce a series of inefficacies such as oil leak, oil sealing come off.
Have this problem just, under some applications, deaerator is designed to be integrated in the camshaft cover cap, to reach good heat insulation effect.Though above-mentioned potential problem has been avoided in this design, tightly be present in usually in the specific engines design.During for example supercharged engine was used, this setup can't be implemented usually at a lot of motors.
Just so, provide a kind of deaerator, it can be avoided, and moisture condenses within it or freezes when lower temperature, really is the technical problem of solution that those skilled in the art needs badly.
[model utility content]
A purpose of the present utility model is intended to, and overcomes the defective that exists in the above-mentioned prior art, and a kind of deaerator of avoiding moisture to condense within it or freezing is provided.

[embodiment]
Understand easily, according to the technical solution of the utility model, do not changing under the connotation of the present utility model, one of ordinary skill in the art can propose a plurality of mode of structure of the present utility model.Therefore following embodiment and accompanying drawing only are to the specifying of the technical solution of the utility model, and should not be considered as of the present utility model all or be considered as qualification or restriction to technical solutions of the utility model.
At first with reference to figure 2, it has illustrated the position of deaerator of the present utility model below.As shown in Figure 2, deaerator 1 of the present utility model is arranged between the gas compressor and intercooler of supercharged engine, wherein, the outlet of gas compressor is connected on the pressurized air inlet 101 of the utility model deaerator 1, and the intercooler inlet is connected in the pressurized air outlet 102 of deaerator 1.As shown in Figure 6, gas flows into and exports 102 through pressurized air passages 110 shown in Figure 3 from pressurized air from pressurized air inlet 101 and flows out.
With reference to figure 1-Fig. 5, deaerator 1 of the present utility model includes housing 11, is arranged on the inner panel 12 of enclosure interior.Wherein, inner panel 12 is divided into two parts of being separated by with the inner space of housing 11, and as shown in FIG., its middle and upper part is a pressurized air passages 110, and the bottom is an Oil-gas Separation passage 120.As shown in Figure 3, pressurized air passages 110 further is connected with and is used for the pressurized air inlet 101 that pressurized air enters and is used for the pressurized air outlet 102 that pressurized air flows out, and described pressurized air inlet 101 and pressurized air outlet 102 are arranged on the sidewall of housing 11.
As shown in Figure 4, the bottom of housing 11 is an Oil-gas Separation passage 120, and as shown in Figure 6, the trend of oil gas is set to opposite with the trend of pressurized air in the pressurized air passages 110 in the Oil-gas Separation passage 120.That is to say that oil gas inlet 104 is set to export 102 places near pressurized air, and oil gas vent 103 is set to export 102 places near pressurized air.
In Oil-gas Separation passage 120, trend along oil gas, be respectively arranged with oil gas pre-separation plate 105, oil gas accelerator card 107, oil-gas separating plate 108, its concrete function mainly is that oil gas is carried out pre-separation and separates, and basic identical in said elements setting and structure and the prior art, therefore seldom give unnecessary details.
Preferably, between oil gas pre-separation plate 105 and oil gas accelerator card 107, also be provided with several cooling fins 106, be used to strengthen the heat exchange effect between pressurized air passages 110 and the Oil-gas Separation passage 120.
In bottom near the housing 11 at oil gas vent 103 places, be provided with outlet 109, be used for the outflow of isolated liquid lubricant oil.
Below with reference to Fig. 6, in pressurized air passages 110, air enters the pressurized air inlet 101 of deaerator 1 from blower outlet after the compression of the gas compressor of pressurized machine, through with the heat exchange of oil gas after, export 102 by pressurized air and enter intercooler.And in Oil-gas Separation passage 120, the flow direction of oil gas is just opposite with pressurized air.As shown in FIG., oil gas enters Oil-gas Separation passage 120 from oil gas inlet 104, by way of oil gas pre-separation plate 105, oil gas accelerator card 107, oil-gas separating plate 108, flow out from oil gas vent 103 at last, a wherein isolated liquid lubricant oil part flows back to from oil gas inlet 104 by the aperture of oil gas pre-separation plate downside, and another part flows back to by exporting 109.Strengthen heat exchange through radiating fin 106, thereby reach the purpose that improves the oil gas temperature.
Understand easily, because after pressurization gas compresses via gas compressor, temperature obviously rises, therefore the utility model is by being integrated in pressurized air passages and Oil-gas Separation passage in the housing, and make it to carry out exchange heat, thereby can use compressed-air actuated heat to heat oil gas, avoid effectively that Yin Wendu crosses the low yield lactogenesisization, phenomenon such as freeze.
