Abstract

The utility model relates to an exhaust pipe for vessel, comprising a main body, wherein the main body is provided inside with an inner shell which is provided with four air inlets corresponding to an air outlet of an engine and has one end provided with an air outlet; the main body is also provided with a liquid inlet hole and a liquid outlet hole through which the liquid flows in and out; the inner shell is a pipe body for diversion, which is extended from the air inlets to the air outlet respectively. The utility model improves the exhaust efficiency and enhances the output effect of the engine by changing the internal structure of the exhaust pipe; moreover, the cooling liquid capacity in the exhaust pipe is increased by 30 to 40 percent, thereby improving the cooling effect of the whole exhaust pipe.

Description

The boats and ships outlet pipe

(1) technical field

The relevant a kind of boats and ships outlet pipe of the utility model.

(2) background technique

Water activity at present gradually the people that are subjected to pay attention to, no matter and be yacht or popular at present racing boat activity, its speed of travelling waterborne then is the effect of exerting oneself that depends on engine, especially with the racing boat activity, if the engine running of device in racing boat is can be smooth and easy, and then the horsepower of racing boat engine just can be brought into play effectively.

Wherein, generally use the engine in racing boat to be V-type eight cylinder engine structures, therefore possessing has two outlet pipes to install place, engine air outlet, the left and right sides at eight cylinder engines respectively, the air that is compressed when engine is operated is discharged, in case the words that the outlet pipe exhaust has some setbacks, the waste gas of engine running is effectively outwards dispatch just, so the horsepower of engine just can't effectively bring into play, and causes the attenuating of engine operational paradigm.

As shown in Figure 5, it is a sectional drawing of commonly using device outlet pipe on engine for boat, it has the main body 20 of a metal forming, main body 20 inside are formed with an inner housing 21, be formed with an air chamber 22 in this inner housing 21, the air outlet hole of relative engine is provided with four inlet holes 220 on this air chamber 22, one end is formed with air outlet hole 221, cooling liquid flows into and the liquid outlet opening 23 and the inlet opening 24 of outflow and also be provided with on the main body 20, when the waste gas of high temperature enters into air chamber 22 via each inlet hole 220, when discharging outlet pipe by air outlet hole 221 again, the gas of high temperature can cause the temperature of outlet pipe inner housing 21 sharply to rise, therefore flow between main body 20 and the inner housing 21 by the inlet opening 24 of cooling liquid by main body 20, flow out main body 20 to take away the high temperature of inner housing 21 via liquid outlet opening 23 again, reduce the bulk temperature of high-temperature exhaust pipe by this.

Yet this kind outlet pipe in use, when high-temp waste gas enters to the air chamber 22 of inner housing 21 via each inlet hole 220, because waste gas fails effectively to guide, this high-temp waste gas can produce the flow-disturbing phenomenon in air chamber 22, this flow-disturbing phenomenon is an impediment to high-temp waste gas and is discharged by the air outlet hole 221 of engine through outlet pipe, therefore can cause the power efficiency of engine undesirable, cause engine horsepower effectively to bring into play, this a kind of phenomenon can cause wasting the fuel oil oil consumption and reduce the engine real horsepower, therefore commonly use the flow-disturbing phenomenon in the outlet pipe air chamber 22 if can be improved, just can promote engine horsepower and have the function of fuel saving oil, allow the operational paradigm of engine be able to more smooth and easy.

(3) model utility content

Main purpose of the present utility model is to provide a kind of pipeline with guide functions, makes outlet pipe inside can not produce internal gas flow-disturbing phenomenon and cause engine to be exerted oneself boats and ships outlet pipe that effect reduces.

For reaching above-mentioned model utility purpose, the utility model is taked following means, technological means of the present utility model is to provide a kind of boats and ships outlet pipe, it has a main body, body interior is formed with an inner housing, and the air outlet hole of relative engine is provided with four inlet holes in this inner housing, and an end is formed with air outlet hole, and also being provided with inlet opening and the liquid outlet opening that cooling liquid flows into and flows out on the main body, this inner housing is for being extended to the water conservancy diversion body of air outlet hole respectively by inlet hole.

For further specifying the purpose of this utility model, structural feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(5) embodiment

As shown in Figures 1 to 4, sectional drawing for the utility model one preferable enforcement kenel, it has the main body 10 of a metal material moulding, main body 10 is provided with the but liquid inlet opening 14 and the liquid outlet opening 13 that flow into and flow out of cooling, in advancing, liquid outlet opening 14, be formed with the shunt of bootable cooling liquid in 13 the main body 10, main body 10 inside are formed with an inner housing 11 again, the air outlet hole of relative engine is provided with four inlet holes 110 in this inner housing 11, one end is formed with air outlet hole 111, and this inner housing 11 is for being extended to the water conservancy diversion body of air outlet hole 111 respectively by inlet hole 110.

Two bodys that wherein are arranged at main body 10 both sides inlet holes 110 respectively are for to be extended to towards the top near main body 10 upper inner wall by inlet hole 110, again with angle parallel bodies 10 upper inner wall that tilt, and extend towards air outlet hole 111 and to be provided with; Two bodys that are arranged at main body 10 central air induction holes 110 respectively then directly upwards extend towards air outlet hole 111 directions and are provided with, and are provided with a dividing plate 112, four bodys between two bodys and meet in the position of air outlet hole 111 to merge to extend towards air outlet hole 11 and be provided with.

Body design via the utility model inner housing 11, make the high-temp waste gas of engine running discharge can be displaced into the position of air outlet hole 111 via the direct water conservancy diversion of body, therefore high-temperature gas can not produce the flow-disturbing phenomenon in inner housing 11, cause the effect of exerting oneself of engine to descend, cause the engine operational paradigm effectively to bring into play.

The utility model also is provided with inlet opening 14 and liquid outlet opening 13 on main body, so cooling liquid can also enter into 11 of main body 10 and inner housings to carry out the cooling action of inner housing 11, in the use and existing engine do not have inapplicable situation and take place.In addition, increase about 30 to 40%, therefore obvious especially because the utility model is commonly used the cooling liquid capacity of outlet pipe inside for the cooling-down effect of whole outlet pipe.

Because when the utility model is discharged the inner housing 11 of high-temp waste gas to outlet pipe in engine running, directly high-temp waste gas is guided to air outlet hole 111 places by the inlet hole 110 of outlet pipe via the body design of inner housing 11, therefore high-temp waste gas can be smoothly discharges via the air outlet hole 111 of outlet pipe, therefore can effectively promote the operational paradigm of engine.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims the above embodiment's variation, modification.
