Description
Technical field
The present invention relates to one to collaborate channel system, especially relate to a kind of channel system of collaborating be integrated in intake manifold.
Background technique
During current most plastic air intake manifold work, utilize collaborating from crankcase, will be collaborated by the house steward's mouth of pipe near throttle body is mixed with fresh air, then enters each pipe of intake manifold, finally enters the cylinder combustion of each correspondence.
Intake manifold is introduced from house steward and is collaborated, and mix with fresh air, can produce the uneven situation of mixing, makes to enter collaborating of each cylinder also uneven, the final circulating combustion mobility affecting motor.In addition under the environment of cold, to collaborate and the blocking that can congeal into ice of moisture content in fresh air is collaborated passage, local compression is sharply increased.
Summary of the invention
Object of the present invention be exactly provide that a kind of harmony is good to overcome defect that above-mentioned prior art exists, storage capacity is strong, be not afraid of the icing channel system of collaborating be integrated in intake manifold.
Object of the present invention can be achieved through the following technical solutions:
A kind of channel system of collaborating be integrated in intake manifold, described intake manifold comprises cover plate of collaborating, to collaborate entrance, lower shell body and upper shell, described upper shell is connected with lower shell body, described lower shell body is connected with cover plate of collaborating, described entrance of collaborating is located at collaborates on cover plate, described lower shell body is connected with the cylinder head of motor by cold plug-in unit, lower shell body flange is provided with in described lower shell body, described channel system of collaborating comprises the enclosed space formed by lower shell body and cover plate of collaborating, two baffle plates are provided with in this enclosed space, four collaborate entrance and four outlets of collaborating, one end of described baffle plate is fixed on lower shell body, two described baffle plates are arranged for symmetry axis with entrance of collaborating, described four collaborate entrance and four outlet distributions of collaborating are arranged on lower shell body flange, four entrances of collaborating are connected respectively by passage correspondence of collaborating with four outlets of collaborating.
Collaborate in entrance for described four, entrance of collaborating between two is arranged about the end symmetrical of a baffle plate.
Described baffle plate is " L " type baffle plate.
Described passage of collaborating is " L " type passage.
The diameter of described passage of collaborating is 3-5mm.
Described cylinder head is provided with sealing ring of cylinder cover, and described outlet of collaborating is positioned at inside sealing ring of cylinder cover.
Also aqua storage tank is provided with in described enclosed space.
Compared with prior art, the present invention has the following advantages:
It is harmonious good: because two baffle plate e and f are about entrance symmetry of collaborating, four entrance a and b that collaborate are about e end symmetrical, c and d is about f end symmetrical, the amount of collaborating entering above-mentioned four entrances of collaborating is almost the same, almost identical on the air inlet impact of intake manifold four pipes so collaborate, cycle of engine Combustion fluctuation rate is smaller;
Storage capacity is strong: because gasoline contains a small amount of moisture, in engine working process, has water vapour liquefaction and forms water, so the aqua storage tank that design comparison is large, can be good at head it off;
The ice of collaborating in passage can be melted in time: under the environment of cold, after engine misses, water vapour in collaborating can congeal into ice, block whole passage of collaborating, the present invention collaborates passage near cylinder head, next time, when restarting motor, the heat that cylinder covers can pass to the passage place of collaborating of intake manifold very soon, and then melted rapidly the ice of collaborating in passage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As Figure 1-Figure 5, a kind of channel system of collaborating be integrated in intake manifold, described intake manifold comprises cover plate 1 of collaborating, to collaborate entrance 9, lower shell body 2, upper shell 3, throttle body seal ring 5, cold plug-in unit 6 and hot plug-in unit 7, after described upper shell 3 and lower shell body 2 Vibration welding, with cover plate 1 Vibration welding of collaborating, entrance 9 of collaborating is independent external, and be located at and collaborate on cover plate 1, described lower shell body 2 is connected with multiple cylinder head 8 of motor through cold plug-in unit 6 by M6 construction bolt, lower shell body flange is provided with in described lower shell body 2, described channel system of collaborating comprises the enclosed space formed by lower shell body 2 and cover plate 1 of collaborating, the baffle plate e of two " L " types is provided with in this enclosed space, f, one end of these two baffle plates is fixed on lower shell body 2, and it is symmetrical about entrance 9 of collaborating.Lower shell body flange has four collaborate entrance a, b, c, d, and wherein a and b is about baffle plate e end symmetrical, c and d is about baffle plate f end symmetrical.
As shown in Figure 2, from direction, cylinder-head flange face, lower shell body flanged surface has four collaborate outlet a ', b ', c ', d ', wherein a ' is connected by the path 10 of collaborating of " L " type with a in Fig. 1, the same, b ' forms with b, c in Fig. 1 ' and c, d in Fig. 1 ' and the d in Fig. 1 passage of independently collaborating respectively, as shown in Figure 3.Collaborate entrance, outlet of collaborating, passage of collaborating equal diameter be 3-5mm, the present embodiment is 4mm.
Described cylinder head 8 is provided with sealing ring of cylinder cover 4, and four outlets of collaborating lay respectively at inside corresponding sealing ring of cylinder cover 4.
Also be provided with aqua storage tank 11 in described enclosed space, many moisture content can be held, as shown in Figure 4.In engine working process, in collaborating, there is water vapour, run into lower shell body and can condense into water with cover plate inwall of collaborating, along with engine running, many water can be produced, these water can be received by aqua storage tank.
The working principle of the above-mentioned channel system of collaborating be integrated in intake manifold is: from the filtration of collaborating through external crankcase ventilation system or valve chamber cover of crankcase, enter the main entrance 9 of collaborating of collaborating on cover plate 1, then along the enclosed space flowing of collaborate cover plate 1 and lower shell body 2 composition, whole enclosed space is split by baffle plate e and f, collaborate along baffle plate e and f and enter the entrance a that collaborates respectively, b and c, d, then to collaborate path 10 in " L " type being 4mm along diameter respectively, eventually through the outlet a ' that collaborates, b ', c ', d ' enters on engine cylinder cap flanged surface, now collaborate and from intake manifold each pipe fresh air mixing (as shown in Figure 3), enter intake duct and firing chamber in engine cylinder cap 8 together, work by combustion is completed in cylinder.
As shown in Figure 5, under the environment of cold, after the engine misses worked long hours, water vapour in collaborating can in the confined space condensation of cover plate 1 and lower shell body 2 composition of collaborating, form ice 12, and then block path 10 of collaborating, when restarting motor next time, each pipe of intake manifold can not be arrived in time from collaborating in crankcase, the local compression of path 10 of collaborating now can be caused sharply to raise, in order to melt ice in time, path 10 of collaborating is arranged on intake manifold cylinder cap flanged surface, intake manifold cylinder cap flanged surface is installed to cylinder and covers, so pass to from the heat of engine cylinder cover path 10 place of collaborating very soon, collaborate like this and normally can enter into each pipe of intake manifold.
