Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
The state diagram in practical set of the motor intake manifold that Fig. 3 provides for the embodiment of the present invention, Fig. 4 is this
The motor intake manifold that bright embodiment provides partial sectional view at rectification baffle plate, Fig. 5 is that rectification baffle plate is in practical set
In state diagram.
Referring to Fig. 3 to Fig. 5, the invention provides a kind of motor intake manifold, including: Oil/Gas Pipe 2 He
Rectification baffle plate 4；Wherein Oil/Gas Pipe 2 is opened on the housing 1.2 of inlet manifold 1, and inlet manifold 1 is by Oil/Gas Pipe 2 and electromotor
On crankcase ventilation system connection；Rectification baffle plate 4 is arranged on the inwall of housing 1.2, and rectification baffle plate 4 is arranged on Oil/Gas Pipe
The lower section of 2 gas outlets.
In engine operation process, the high-temperature oil gas in crankcase ventilation system enters inlet manifold 1 by Oil/Gas Pipe 2
Inner chamber, rebounds with rectification baffle plate 4 collision rift, makes the flow direction of oil gas to change, and oil gas can be along housing 1.2 inwall stream
Dynamic, meanwhile, air enters air line 3.1 and enters the inner chamber of inlet manifold 1 after the cooling of charge air cooler 3, and makes oil gas
Become impact, make oil gas flow into rapidly air intake duct 1.1 and enter cylinder and burn.
Further, the side of rectification baffle plate 4 is provided with the structure bent inwards, and the opening part of bending structure and oil gas
The gas outlet of pipe 2 is relative.
In order to make oil gas can move upward along housing 1.2 inwall, rectification baffle plate 4 can be arranged to " L " shape, and " L " shape
Opening relative with the gas outlet of Oil/Gas Pipe 2, and then oil gas can be rebounded.
Further, housing 1.2 is provided with sunk structure 1.3, this sunk structure 1.3 be on housing 1.2 from inside to outside
One convex structure of depression, and sunk structure 1.3 is arranged in inlet manifold 1 on the direction of gas flow and near Oil/Gas Pipe
Position above in the of 2.
Further, the tangent line at place at sunk structure 1.3 and the flex point 1.4 that is connected with the housing 1.2 on adjacent position
There is the angle of setting.
After rectification baffle plate 4 will enter the oil gas bounce-back of Oil/Gas Pipe 2, it is to avoid oil gas flows to charge air cooler 3 directly down, and makes
Oil gas flows up along housing 1.2 inwall, owing to the housing 1.2 between air intake duct 1.1 and rectification baffle plate 4 is arc structure, therefore
The movement locus of oil gas is also camber line, but charge air cooler 3 be on direction straight up blowout cold air, thus can cause cold air with
Oil gas collision rift can produce the component on any direction, makes the track of oil gas be broken up by cold air, so cause a part of oil gas to
The direction motion of charge air cooler 3, is condensed into fluid, pollutes charge air cooler 3 after mixing with cold air, meanwhile, the random flowing of oil gas is led
The oil gas causing the entrance of each air intake duct 1.1 is uneven, thus causes gas concentration in the cylinder having higher and burn insufficient, and has
Cylinder gas concentration thin cause burning, and then damage electromotor.
So, in order to avoid the generation of this problem, the direction of gas flow is provided with sunk structure 1.3, makes oil
Gas is after rectification baffle plate 4 bounce-back changes flow direction, then makes oil gas flow direction generation secondary turn through sunk structure 1.3
Become, and at sunk structure 1.3 and the flex point 1.4 that is connected with the housing 1.2 on adjacent position, the tangent line at place has the angle of setting
Degree, makes oil gas cold air and oil gas collision rift can be made can to produce on direction initialization along housing 1.2 to the direction flowing set
Make a concerted effort, and then make oil gas the most quickly flow into air intake duct 1.1, it is to avoid oil gas is impacted by cold air to be affected and flows to charge air cooler 3
Problem, also ensure that oil gas flow in each cylinder equably, it is achieved that the harmonious combustion of each cylinder simultaneously.
Partial sectional view at rectification baffle plate in another embodiment that Fig. 6 provides for the present invention, Fig. 7 is that the present invention provides
Another embodiment in rectification baffle plate other direction on sectional view.
Referring to Fig. 6 and Fig. 7, rectification baffle plate 4 is arranged to the groove type structure of side-closed, ties relative to " L " shape
The rectification baffle plate 4 of structure, the rectification baffle plate 4 of the groove type structure of side-closed can make gas only flow up from groove, and
The both sides of the rectification baffle plate 4 of " L " shape are unobstructed, and oil gas both can flow upwards out, it is also possible to from the both sides of " L " shape rectification baffle plate 4
Flow out, so, the rectification baffle plate of groove type structure can be more concentrated at retraining the direction of oil gas flowing.
Certainly, in order to enable preferably to control the direction of oil gas flowing, it is to avoid oil gas flows to charge air cooler, makes oil gas in cylinder
Flowing evenly, it would however also be possible to employ the rectification baffle plate of other version, this present embodiment is repeated no more.
The embodiment of the present invention additionally provides a kind of electromotor, including crankcase ventilation system and charge air cooler 3, wherein, and this
Motivation also includes the motor intake manifold that any embodiment of the present invention provides.
The motor intake manifold that the embodiment of the present invention provides, solves oil gas and blows to charge air cooler and be condensed out asking of fluid
Topic, improves the cleannes in inlet manifold and charge air cooler, also achieves the uniform distribution of each cylinder oil gas simultaneously, and then make oil
Gas fully burns in each cylinder of electromotor.
The structure of the present invention, feature and action effect, above institute are described in detail above according to graphic shown embodiment
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
Want made change, or be revised as the Equivalent embodiments of equivalent variations, still without departing from description and diagram contained spiritual time,
All should be within the scope of the present invention.
