Abstract
The utility model discloses a kind of EGR waste gas uniform mixing device of motor, aim to provide the simple and mixing arrangement that waste gas mixing uniformity is good of a kind of structure.It comprises the intake manifold that is provided with exhaust gas entrance, is positioned at the annular groove that described intake manifold inwall is connected with exhaust gas entrance, and described annular groove extends to opposite side from exhaust gas entrance side and ending near opposite side; It also comprises a cylindrical body tube wall being provided with some through holes, described cylindrical body is set in both sides that in intake manifold and two ends exceed annular groove and is formed and closely cooperate, the moieties into close that the outer side wall of described cylindrical body is corresponding with annular groove cut-off place contacts, and makes annular groove form the annular housing with partition; The form that described through hole increases gradually by diameter is along the distribution of cylindrical body circumference, and the less through hole in aperture is positioned at the exhaust gas entrance place of intake manifold, and the larger through hole in aperture is away from the exhaust gas entrance of intake manifold.The utility model is applicable to all kinds of motor and uses.
Description
Technical field
The utility model relates to technical field of engines, especially relates to a kind of EGR waste gas uniform mixing device of motor.
Background technique
EGR EGR(Exhaust Gas Recirculation) be under the not significantly reduced prerequisite of guarantee engine power performance, the some of motor combustion gas is sent back to suction tude again according to the temperature of motor and payload, and again enter cylinder participation burning after mixing with fresh air or incoming mixture, slow down combustion velocity, reduce combustion temperature, thus reduce the discharge amount of nitrogen oxides.Along with society constantly strengthens environmental consciousness, improving constantly of engine emission levels, EGR plays indispensable role in the process promoting emission level, imperative to the raising of the uniformity that EGR waste gas mixes with fresh air.
The EGR waste gas uniform mixing device complex structure of current use, manufacture cost is high, and waste gas mixing uniformity is poor.
Summary of the invention
The utility model overcomes shortcoming of the prior art, provides the simple and EGR waste gas uniform mixing device of the motor that waste gas mixing uniformity is good of a kind of structure.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of EGR waste gas uniform mixing device of motor, comprises the intake manifold that is provided with exhaust gas entrance; Be positioned on described intake manifold inwall and be provided with the annular groove be connected with exhaust gas entrance, described annular groove extends to opposite side from exhaust gas entrance side and is ending near opposite side; It also comprises a cylindrical body tube wall being provided with some through holes, described cylindrical body is set in both sides that in intake manifold and two ends exceed annular groove and is formed and closely cooperate, the moieties into close that the outer side wall of described cylindrical body is corresponding with annular groove cut-off place contacts, and makes annular groove form the annular housing with partition; The form that described through hole increases gradually by diameter is along the distribution of cylindrical body circumference, and the less through hole in aperture is positioned at the exhaust gas entrance place of intake manifold, and the larger through hole in aperture is away from the exhaust gas entrance of intake manifold.
Preferably, described cylindrical body adopts corrosion resistant aluminum material to make.
Preferably, described through hole is circular port.
Compared with prior art, the utility model tool has the following advantages:
(1) the utility model structure is simple, cheap for manufacturing cost, fast easy to assembly.According to the velocity flow profile of intake manifold exhaust gas entrance place waste gas, the size of through hole on cylindrical body is rationally set, make the aperture of waste gas flow velocity biggest place (i.e. exhaust gas entrance place) minimum, realize flow cross section and flow velocity to be inversely proportional to setting, and then make the flow of each through hole basically identical, ensure good waste gas mixed effect.Have the air-flow one-way flow that the annular housing of partition can make in annular housing, stream pressure is comparatively stable, there will not be the problem of annular housing flow perturbation simultaneously, and ensure best through hole air inlet effect, waste gas mixing uniformity is good.
(2) cylindrical body of the present utility model adopts corrosion resistant aluminum material to make, and can not lose efficacy under the operating mode of high-temp waste gas for a long time, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is sectional view of the present utility model;
Fig. 2 be the utility model gas flow to schematic diagram;
Fig. 3 is the stereogram of cylindrical body in the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The EGR waste gas uniform mixing device of motor shown in Fig. 1-3, comprises the intake manifold 1 that is provided with exhaust gas entrance 2, on the tube wall that exhaust gas entrance 2 is arranged at intake manifold 1 and close to air inlet place; Be positioned on described intake manifold 1 inwall and be provided with the annular groove 3 be connected with exhaust gas entrance 2, described annular groove 3 extends to opposite side from exhaust gas entrance 2 side and is ending near opposite side; It also comprises the cylindrical body 4 tube wall being provided with some manholes 5, and described cylindrical body 4 adopts corrosion resistant aluminum material to make.This cylindrical body 4 is set in both sides that in intake manifold 1 and two ends exceed annular groove 3 and is formed and closely cooperate, and the moieties into close that the outer side wall of cylindrical body 4 is corresponding with annular groove 3 cut-off place contacts, and makes annular groove 3 formation have the annular housing of partition; The form that described through hole 5 increases gradually by diameter is along the distribution of cylindrical body 4 circumference, and the less through hole 5 in aperture is positioned at exhaust gas entrance 2 place of intake manifold 1, and the larger through hole 5 in aperture is away from the exhaust gas entrance 2 of intake manifold 1.
The utility model structure is simple, cheap for manufacturing cost, fast easy to assembly.According to the velocity flow profile of intake manifold exhaust gas entrance place waste gas, the size of through hole on cylindrical body is rationally set, make the aperture of waste gas flow velocity biggest place (i.e. exhaust gas entrance place) minimum, realize flow cross section and flow velocity to be inversely proportional to setting, and then make the flow of each through hole basically identical, ensure good waste gas mixed effect.Have the air-flow one-way flow that the annular housing of partition can make in annular housing, stream pressure is comparatively stable, there will not be the problem of annular housing flow perturbation simultaneously, and ensure best through hole air inlet effect, waste gas mixing uniformity is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
