Automobile-used egr system structure mainly comprises exhaust steam passage, EGR control valve and waste gas cooling channel.Egr system adopts the complicated pipelines system more or casts pipeline on the market now, and waste gas is introduced cylinder cap air flue or intake manifold, reduces the purpose that pump is inhaled loss and improved burning to reach.Common manufacturing process more complicated, cost of production is higher.Because spatial arrangement is often restricted, and waste gas air inlet position is difficult to accomplish optimum, is difficult to accomplish the equilibrium of multi-cylinder EGR air inlet rate, worsen engine performance simultaneously, run in the opposite direction with application purpose.
Summary of the invention
The present invention has designed a kind of compact type EGR channel design; The technical problem of its solution is that the egr system that has now adopts the complicated pipelines system more or casts pipeline, has the equilibrium that manufacture cost is high, spatial arrangement is often restricted and be difficult to accomplish multi-cylinder EGR air inlet rate.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of compact type EGR channel design, it is characterized in that: the EGR channel design is arranged on engine cylinder and covers, and said EGR channel design is with the balanced engine intake passage of introducing of waste gas.
Further; Said EGR channel design comprises EGR inlet hole (4), gas-entered passageway (8), outlet passageway (7) and a plurality of EGR air outlet hole (3), and waste gas is successively through EGR inlet hole (4), gas-entered passageway (8), outlet passageway (7) and EGR air outlet hole (3); A plurality of EGR air outlet holes (3) get into respectively in each cylinder body through engine intake passage.
Further, be communicated with through one or more attachment holes (9) between said gas-entered passageway (8) and the said outlet passageway (7).
Further, said gas-entered passageway (8) is arranged in parallel with said outlet passageway (7).
Further, said gas-entered passageway (8) is positioned at said outlet passageway (7) below.
Further, said EGR channel design is the Cylindrical object structure of a compactness.
Further, when said EGR channel design is passed through processing or casting, go up formation a plurality of first Bowl Plug (5) and a plurality of second Bowl Plug (6) at gas-entered passageway (8) and outlet passageway (7).
Further, said first Bowl Plug (5) and said second Bowl Plug (6) are plug or steel ball.
Further, on said EGR channel design, be provided with construction bolt hole (2), the mode that said EGR channel design cooperates through bolt and construction bolt hole (2) is fixed on said engine cylinder and covers.
Egr system is compared on this compact type EGR channel design and the traditional market, has following beneficial effect:
(1) EGR channel design of the present invention is compact Cylindrical object structure, thereby the engine cylinder that is installed in that can be easy covers, and is applicable to the layout under the narrow and small limited situation in space, and has good manufacturing process.
(2) EGR channel design of the present invention adopts a plurality of EGR air outlet holes to get into respectively in each cylinder body through engine intake passage, and realizes getting into the EGR exhausted air quantity equilibrium of each cylinder.Guaranteed that the EGR function-stable is realized and suitable batch process the in batches.

Embodiment
Below in conjunction with Fig. 1 to Fig. 5, the present invention is further specified:
As shown in Figure 1, EGR channel design 1 comprises an EGR inlet hole 4 and a plurality of EGR air outlet holes 3, and a plurality of EGR air outlet holes 3 get into respectively in each cylinder body through engine intake passage, and realizes getting into the EGR exhausted air quantity equilibrium of each cylinder.
On EGR channel design 1, be provided with construction bolt hole 2, the mode that EGR channel design 1 cooperates through bolt and construction bolt hole 2 is fixed on engine cylinder and covers.
As shown in Figure 2, when EGR channel design 1 is passed through processing or casting, on gas-entered passageway 8 and outlet passageway 7, form a plurality of first Bowl Plug 5 and a plurality of second Bowl Plug 6.First Bowl Plug 5 and second Bowl Plug 6 are plug or steel ball.
As shown in Figure 3, gas-entered passageway 8 is positioned at the below of outlet passageway 7, and EGR inlet hole 4 is vertically connected on the gas-entered passageway 8.
As shown in Figure 4, gas-entered passageway 8 is positioned at the below of outlet passageway 7, and EGR air outlet hole 3 is vertically connected on the outlet passageway 7.
