Abstract

The utility model relates to an integrated EGR (exhaust gas recirculation) channel structure which comprises an EGR channel body (5), EGR gas inlet holes (1) and EGR gas outlet holes (3) are arranged on the EGR channel body (5), and an EGR valve (4) is directly integrated on the EGR channel body (5). Since the EGR valve is directly integrated on the EGR channel body (5), casting, machining and installing processes are simple, installation period is shortened greatly, and work efficiency is improved.

Description

A kind of integrated type EGR channel design
Technical field
The utility model relates to a kind of EGR channel design, especially relates to a kind of integrated type EGR channel design.
Background technique
Along with the pay attention to day by day of international community to environmental protection and using energy source, vehicular engine Abgasgesetz day is tight increasingly.Therefore, adopt more advanced engine technology, reduce discharging and CO 2Discharging becomes the important means of each automobile, internal-combustion engine manufacturer.EGR(EGR wherein) technology has become a kind of effective means that reduces discharging and oil consumption, more and more is applied on the vehicular engine.
Automobile-used egr system structure mainly comprises exhaust steam passage, EGR control valve and waste gas cooling channel.Egr system adopts complicated pipe-line system or casting pipeline more on the market now, and waste gas is introduced performance or intake manifold, reduces the purpose that pump is inhaled loss and improved burning to reach.Be subjected to the restriction of arrangement space, common manufacturing process more complicated, cost of production is higher.
Summary of the invention
The utility model has designed a kind of integrated type EGR passage, and the technical problem of its solution is that (1) existing EGR valve is installed and must be carried out after the EGR passage is installed, and causes the increase of installation work-hour, and working efficiency is not high; (2) existing EGR valve position is not positioned on the EGR passage, and easy occupying volume is more space outward, affects the layout of miscellaneous part.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of integrated type EGR passage comprises EGR channel body (5), is provided with EGR inlet hole (1) and EGR air outlet hole (3) in described EGR channel body (5), and EGR valve (4) directly is integrated on the described EGR channel body (5).
Further, an end of described EGR channel body (5) is provided with the EGR valve joint (2) is installed, and described EGR valve (4) is fixed on described EGR valve and installs on the joint (2).
Further, described EGR valve is installed joint (2) and is had bolt mounting holes (21), and described EGR valve (4) is installed joint (2) with described EGR valve and is fixed with the mode that bolt mounting holes (21) is connected by fixing bolt (41).
Further, described EGR channel body (5) seals by a plurality of Bowl Plug (6).
This integrated type EGR passage is compared with traditional E GR passage, has following beneficial effect:
(1) the utility model is owing to directly be integrated in the EGR valve on the EGR channel body, thereby casting, processing and mounting process are simple, have greatly reduced installation work-hour, have improved working efficiency.
(2) the utility model is owing to directly be integrated in the EGR valve on the EGR channel body, thereby optimized arrangement structure, realize arranging the compactest, can the outer more space of occupying volume, can not affect the layout of miscellaneous part.

Embodiment
Below in conjunction with Fig. 1 to Fig. 4, the utility model is described further:
A kind of integrated type EGR passage comprises EGR channel body 5, is provided with EGR inlet hole 1 and EGR air outlet hole 3 in EGR channel body 5, and EGR valve 4 directly is integrated on the EGR channel body 5.One end of EGR channel body 5 is provided with the EGR valve joint 2 is installed, and EGR valve 4 is fixed on the EGR valve and installs on the joint 2.The EGR valve is installed joint 2 and is had bolt mounting holes 21, and EGR valve 4 is installed joint 2 with the EGR valve and is fixed with the mode that bolt mounting holes 21 is connected by fixing bolt 41.EGR channel body 5 seals by a plurality of Bowl Plug 6.
The working principle of this integrated type EGR passage is as follows:
During work, EGR waste gas enters EGR channel body 5 by EGR inlet hole 1, and the EGR valve 4 through the controllable flow rate size enters engine intake passage or firing chamber from EGR air outlet hole 3 again.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all in protection domain of the present utility model.
