The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and is only used for explaining the present invention, and is not construed as limiting the claims.
Fig. 3 is the state diagram in practical set of motor intake manifold provided in an embodiment of the present invention, and Fig. 4 is this hair
Partial sectional view of the motor intake manifold that bright embodiment provides at rectification baffle plate, Fig. 5 are rectification baffle plate in practical set
In state diagram.
Referring to Fig. 3 to Fig. 5, the present invention provides a kind of motor intake manifold, including：2 He of Oil/Gas Pipe
Rectification baffle plate 4；Wherein Oil/Gas Pipe 2 is opened on the shell 1.2 of inlet manifold 1, and inlet manifold 1 passes through Oil/Gas Pipe 2 and engine
On crankcase ventilation system connection；Rectification baffle plate 4 is arranged on the inner wall of shell 1.2, and rectification baffle plate 4 is arranged in 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 cavity rebounds after being collided with rectification baffle plate 4, makes the flow direction of oil gas that can change, oil gas can be along 1.2 inner wall stream of shell
It is dynamic, meanwhile, air enters air pipeline 3.1 and enters the inner cavity of inlet manifold 1 after the cooling of charge air cooler 3, and is made to oil gas
At impact, oil gas is made to flow into air intake duct 1.1 rapidly and burn into cylinder.
Further, the side of rectification baffle plate 4 is provided with the structure to bend inwards, and the opening and oil gas of bending structure
The gas outlet of pipe 2 is opposite.
In order to allow oil gas to be moved upwards along 1.2 inner wall of shell, rectification baffle plate 4 can be arranged to " L " shape, and " L " shape
Opening it is opposite with the gas outlet of Oil/Gas Pipe 2, and then oil gas can be rebounded.
Further, be provided with sunk structure 1.3 on shell 1.2, the sunk structure 1.3 be shell 1.2 on from inside to outside
One convex structure of recess, and sunk structure 1.3 is arranged in inlet manifold 1 on the direction of gas flow and close to Oil/Gas Pipe
The position of 2 tops.
Further, sunk structure 1.3 and 1.4 place of inflection point that is connect with the shell 1.2 on adjacent position tangent line
Angle with setting.
It after rectification baffle plate 4 will enter the oil gas rebound of Oil/Gas Pipe 2, avoids oil gas and flows to charge air cooler 3 directly down, and make
Oil gas is flowed up along 1.2 inner wall of shell, since the shell 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 is to blow out cold air on direction straight up, to can cause cold air with
Will produce component on any direction after oil gas collision, the track of oil gas made to be broken up by cold air, so cause a part of oil gas to
The direction of charge air cooler 3 moves, and fluid is condensed into after being mixed with cold air, pollutes charge air cooler 3, meanwhile, the random flowing of oil gas is led
Cause the oil gas that each air intake duct 1.1 enters uneven, so as to cause gas concentration in the cylinder having is higher and it is insufficient to burn, and have
Cylinder gas concentration it is thin lead to burning, and then damage engine.
So in order to avoid the generation of this problem, it is provided with sunk structure 1.3 on the direction of gas flow, makes oil
Gas makes oil gas flow direction occur secondary turn after rectification baffle plate 4 rebounds and changes flow direction using sunk structure 1.3
Become, and sunk structure 1.3 and 1.4 place of inflection point that connect with the shell 1.2 on adjacent position tangent line there is the angle set
Degree allows oil gas to be flowed to the direction of setting along shell 1.2, can be generated on direction initialization after so that cold air is collided with oil gas
With joint efforts, and then oil gas is made directly quickly to flow into air intake duct 1.1, avoid oil gas is influenced to flow to charge air cooler 3 by cold air impact
The problem of, while also ensuring that oil gas is equably flow in each cylinder, realize the harmonious combustion of each cylinder.
Fig. 6 is that the partial sectional view at rectification baffle plate, Fig. 7 provide for the present invention in another embodiment provided by the invention
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, relative to " L " shape knot
The rectification baffle plate 4 of the rectification baffle plate 4 of structure, the groove type structure of side-closed can be such that gas is only flowed up from groove, and
The both sides of the rectification baffle plate 4 of " L " shape are unobstructed, and oil gas can both flow upwards out, can also be from the both sides of " L " shape rectification baffle plate 4
Outflow, so, the rectification baffle plate of groove type structure can be more concentrated at the direction of constraint oil gas flowing.
Certainly, it in order to preferably control the direction of oil gas flowing, avoids oil gas from flowing to charge air cooler, makes oil gas into cylinder
Flowing evenly, can also use other structures form rectification baffle plate, to this, this embodiment is not repeated.
The embodiment of the present invention additionally provides a kind of engine, including crankcase ventilation system and charge air cooler 3, wherein the hair
Motivation further includes the motor intake manifold that any embodiment of the present invention provides.
Motor intake manifold provided in an embodiment of the present invention solves oil gas and blows to charge air cooler and be condensed out asking for fluid
Topic, improves the cleannes in inlet manifold and charge air cooler, while also achieving evenly distributing for each cylinder oil gas, and then make oil
Gas fully burns in each cylinder of engine.
The structure, feature and effect of the present invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
