Abstract
The utility model relates to a kind of cold water shell type outlet pipe, belongs to the technical field of engine design and manufacture.Outlet pipe described in the utility model comprises the body with exhaust passage of casting, is formed with cooling jacket, and the outer wall of cooling jacket is formed with casting sand outlet on the outer wall of described body.The utility model selects founding type outlet pipe, and cooling jacket is integrated with on outlet pipe, engine cooling water is incorporated into the cooling jacket of outlet pipe, the temperature reducing outlet pipe makes extend the working life of outlet pipe, reduce the discharge amount of NOx simultaneously, and decrease the thermal radiation of its Surrounding Parts, improve the reliability of motor.
Description
Technical field
The utility model belongs to the technical field of engine design and manufacture, and in particular, the utility model relates to a kind of cold water shell type outlet pipe.
Background technique
Gas exhaust manifold is integrated in the motor in cylinder cap, outlet pipe in the past adopts single bent-tube boiler or founding type, and high-temp waste gas is directly discharged to outlet pipe, makes outlet pipe thermal fatigue serious, easily ruptures.Also make ambient temperature raise, component thermal radiation increases the weight of, reduced lifetime.In addition, the higher meeting of delivery temperature causes the discharge amount of NOx compound to increase, and the performance of motor is reduced.
Model utility content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of cold water shell type outlet pipe.
To achieve these goals, the utility model have employed following technological scheme:
A kind of cold water shell type outlet pipe, is characterized in that: the body with exhaust passage comprising casting, is formed with cooling jacket, and the outer wall of cooling jacket is formed with casting sand outlet on the outer wall of described body.
Wherein, described body is also provided with the water outlet and water inlet that are communicated to described cooling jacket.
Compared with prior art, cold water shell type outlet pipe described in the utility model has following beneficial effect:
The utility model selects founding type outlet pipe, and cooling jacket is integrated with on outlet pipe, engine cooling water is incorporated into the cooling jacket of outlet pipe, the temperature reducing outlet pipe makes extend the working life of outlet pipe, reduce the discharge amount of NOx simultaneously, and decrease the thermal radiation of its Surrounding Parts, improve the reliability of motor.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the cold water shell type outlet pipe of embodiment 1.
Fig. 2 is the cross-sectional structure schematic diagram of the cold water shell type outlet pipe of embodiment 1.
Fig. 3 is the engine structure schematic diagram adopting prior art outlet pipe.
Embodiment
Be further elaborated cold water shell type outlet pipe described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Figure 1-2, the cold water shell type outlet pipe described in the present embodiment, comprises the body 5 with exhaust passage of casting, on the outer wall of described body, is formed with cooling jacket 3, and the outer wall of cooling jacket is formed with casting sand outlet 4.State the water outlet 1 and water inlet 2 that described body are also provided with and are communicated to described cooling jacket.Cooling water inlet is connected with cylinder cap water outlet, and water outlet is connected with car load warm-air drier.Outlet pipe has had cooling, and delivery temperature reduces, and reduces ambient temperature, reduces and endanger the thermal radiation of other component.Adopt the motor of the present embodiment scheme, select founding type outlet pipe scheme, and on outlet pipe, cast cooling jacket, centre is provided with waterwall, ensures the flow direction of cooling water, effectively reduces the temperature of outlet pipe.The cooling water inlet of outlet pipe is connected with the water outlet of cylinder cap, and outlet pipe water outlet is connected with car load warm-air drier, and the temperature that this scheme reduces outlet pipe makes extend the working life of outlet pipe, reduces the discharge amount of NOx simultaneously, improves engine performance.
As shown in Figure 3, outlet pipe of the prior art adopts single bent-tube boiler or founding type, and because gas exhaust manifold is integrated in cylinder cap 21 inside, waste gas directly discharges cylinder 23, causes outlet pipe 22 temperature too high, makes outlet pipe 22 thermal fatigue well damage.Ambient temperature raises, and component thermal radiation increases the weight of, reduced lifetime.In addition, the higher meeting of delivery temperature causes the discharge amount of NOx compound to increase, and engine performance reduces.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
Claims (2)
1. a cold water shell type outlet pipe, is characterized in that: the body with exhaust passage comprising casting, is formed with cooling jacket, and the outer wall of cooling jacket is formed with casting sand outlet on the outer wall of described body.
2. cold water shell type outlet pipe according to claim 1, is characterized in that: described body is also provided with the water outlet being communicated to described cooling jacket and water inlet.
