Description
Technical field
The present invention relates to a kind of inlet manifold, more particularly, to a kind of inlet manifold of recyclegas high combustion efficiency.
Background technology
At present, influence very severe of the exhaust emission of vehicle to environment, it is one very important to reduce waste gas discharge
Problem.One of which reduce waste gas method be：By the mixed gas in crankcase, import in engine combustion room and carry out again
Burning.What this method can not only circulate utilizes waste gas, economizes on resources, can also reduce the pollution to environment.However, current
Most of design in, mixed gas, which can not be equably imported into each cylinder of engine, fully burns, and have impact on the work of engine
Make performance.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of simple in construction, reduction
The inlet manifold of the recyclegas high combustion efficiency of disposal of pollutants.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of inlet manifold of recyclegas high combustion efficiency, including manifold upper shell, manifold lower house, crankcase ventilation
Cover plate and crankcase bleed pipe, described manifold upper shell are connected with manifold lower house, form entering with multiple pipelines
Gas manifold assembly, described crankcase ventilation cover plate are connected with manifold lower house, and described crankcase bleed pipe is connected to bent axle
The centre position of case vent flap, described manifold lower house form a return cavity, the return cavity with crankcase ventilation cover plate
Interior to be provided with deflector, described deflector is connected with manifold lower house, and described return cavity is distinguished by multiple return cavity passages
Connection corresponding with multiple pipelines.
Described deflector is " L " type baffle plate.
Described deflector is provided with two, and two deflectors are symmetrical arranged on crankcase bleed pipe.
The number that described return cavity passage is provided with is equal with the number of the pipeline.
Compared with prior art, the present invention has advantages below：
1st, it is simple in construction：The present invention is drained by deflector to various gases, and by return cavity passage by gas
Transport in multiple pipelines of inlet manifold assembly, it is simple in construction, die cost, and the usage amount of material will not be significantly increased；
2nd, mixed gas is equably imported into each cylinder of engine by the present invention by deflector fully burns, and improves combustion
Economy and the performance of engine are burnt, and reduces pollution of the emission to environment.
Brief description of the drawings
Fig. 1 is the structural representation of side of the present invention；
Fig. 2 is the positive structural representation of the present invention；
Fig. 3 is the enlarged drawing at A in Fig. 2.
In figure shown in label：
1st, manifold upper shell, 2, manifold lower house, 3, crankcase ventilation cover plate, 4, manifold outlet, 5, manifold entrance, 6, return
Return chamber passage, 7, deflector, 8, return cavity, 9, crankcase bleed pipe.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As Figure 1-Figure 2, a kind of inlet manifold of recyclegas high combustion efficiency, including under manifold upper shell 1, manifold
Housing 2, crankcase ventilation cover plate 3 and crankcase bleed pipe 9, described manifold upper shell 1 are connected with manifold lower house 2, are formed
One inlet manifold assembly for carrying manifold entrance 5, manifold outlet 4 and four pipelines, described crankcase ventilation cover plate 3 and discrimination
Pipe lower house 2 connects, and described crankcase bleed pipe 9 is connected to the centre position of crankcase ventilation cover plate 3, under described manifold
Housing 2 and one return cavity 8 of composition of crankcase ventilation cover plate 3, the interior deflector 7 for being provided with two " L " types of the return cavity 8, two
Deflector 7 is symmetrically connected on manifold lower house 2 on crankcase bleed pipe 9, and described return cavity 8 passes through four return cavities
The connection corresponding with four pipelines respectively of passage 6.
Crankcase bleed pipe 9 on crankcase ventilation cover plate 3 returns machine oil mixed gas and waste gas to be directed into again
Return in chamber 8, then reached by return cavity 8 in four pipelines of inlet manifold assembly, finally, pass through each pipeline to engine
Burnt in each cylinder body of combustion chamber.
As shown in figure 3, in the cavity of return cavity 8, the deflector 7 of L-type can make machine oil mixed gas and waste gas more equal
Even enters in each manifold channels, so that the air inflow of each cylinder body of engine is more uniform, can fully fire
Burn.The invention is effectively improved the economy of burning and the performance of engine, and reduces pollution of the emission to environment.
