Abstract
The utility model discloses a kind of novel exhaust pipeline system; It comprises butterfly valve, exhaust compensator and SCR case, and butterfly valve inlet end is provided with the first clip, and butterfly valve outlet side is connected, by the 3rd clip connected between exhaust compensator and SCR case by the compensator flexible pipe of the second clip with exhaust compensator.Predominant use and advantage: engine supercharger outlet directly connects butterfly valve, greatly reduces the distance between butterfly valve and pressurized machine.Adopt integrated butterfly valve, increase butterfly valve internal diameter, promote exhaust brake performance.Add the length of flexible pipe live part, promote the compensation ability of exhaust compensator, effectively reduce the impact of vibration to SCR case.Whole like this pipe-line system trend is milder, and flex point is less, and it is more reasonable to arrange, air-flow is more smooth and easy; System back pressure is lower, effectively reduces oil consumption.Pipe-line system part kind is less, and cost is lower, and reduces assembling intensity, can improve efficiency of assembling, keeps in repair also more convenient.
Description
Technical field
The utility model relates to engine of heavy-duty car venting gas appliance technical field, is specifically related to a kind of novel exhaust pipeline system.
Background technique
Existing engine of heavy-duty car tail gas, in order to reach emission standard requirement, be connected with SCR case (selective catalytic reduction silencing apparatus) afterwards at pressurized machine, waste gas, after SCR case catalytic reduction, enters air.Connecting pipeline structure between pressurized machine and SCR case is, butterfly valve 2 front end is connected with engine supercharger the first clip 1 by tracheae 10, and rear end is connected with exhaust compensator 5, and exhaust compensator 5 connects tracheae 10 with the second clip 3 below; Tracheae 10 is connected with SCR case 9 the 3rd clip 6 below.Butterfly valve 2 is fixed on support 4, and support 4 is fixed on engine body.SCR case 9 and SCR box bracket 8 SCR case band band 7 are fixed together; SCR box bracket 8 is fixed on vehicle frame.
Oil consumption always is the topic that user pays special attention to, and is also to one of index of car load value assessment.Oil consumption height directly has influence on the user cost of automobile, has influence on the vital interests of each user.Therefore, reduce oil consumption extremely important, the measure reducing oil consumption has a lot, and one of them is optimized gas discharge pipe system structure exactly, to keep airflow smooth, thus reduces gas-flow resistance, reduces exhaust back pressure.Reduce vent systems back pressure, reduce complete-vehicle oil consumption, be applicable to meet state four emission standard requirement.
Summary of the invention
The utility model is for the deficiency existed in background technique, and the technical problem that solve is: the novel exhaust pipeline system providing a kind of low vent systems back pressure, low complete-vehicle oil consumption.
The utility model is for solving the problems of the technologies described above, the technological scheme taked is: a kind of novel exhaust pipeline system, comprise butterfly valve, exhaust compensator and SCR case, butterfly valve inlet end is provided with the first clip, butterfly valve outlet side is connected, by the 3rd clip connected between exhaust compensator and SCR case by the compensator flexible pipe of the second clip with exhaust compensator.
Further, described butterfly valve adopts integrated butterfly valve.
Further, the length of described compensator flexible pipe increases.
Compared with prior art, beneficial effect is the utility model: engine supercharger outlet directly connects butterfly valve, greatly reduces the distance between butterfly valve and pressurized machine.Adopt integrated butterfly valve, increase butterfly valve internal diameter, promote exhaust brake performance.Add the length of flexible pipe live part, promote the compensation ability of exhaust compensator, effectively reduce the impact of vibration to SCR case.Whole like this pipe-line system trend is milder, and flex point is less, and it is more reasonable to arrange, air-flow is more smooth and easy; System back pressure is lower, effectively reduces oil consumption.Pipe-line system part kind is less, and cost is lower, and reduces assembling intensity, can improve efficiency of assembling, keeps in repair also more convenient.
accompanying drawing explanation
Fig. 1 is existing heavy duty automobile exhaust tube road system architecture schematic diagram;
Fig. 2 is the structural representation of one of the utility model mode of execution.
Wherein: 1, the first clip; 2, butterfly valve; 3, the second clip; 4, support; 5, compensator is vented; 5-1, compensator flexible pipe; 6, the 3rd clip; 7, SCR case band band; 8, SCR box bracket; 9, SCR case, 10, tracheae.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described in further detail.
See shown in Fig. 1 to Fig. 2, novel exhaust pipeline system, comprise butterfly valve 2, exhaust compensator 5 and SCR case 9, butterfly valve 2 inlet end is provided with the first clip 1, butterfly valve 2 outlet side is connected by the compensator flexible pipe 5-1 of the second clip 3 with exhaust compensator 5, and exhaust compensator 5 is connected by the 3rd clip 6 with between SCR case 9.Engine supercharger outlet directly connects butterfly valve 2, eliminates the tracheae 10 in original pipeline, greatly reduces the distance between butterfly valve 2 and pressurized machine.
Expand caliber to gas exhaust piping, adopt Ф 110 external diameter, compare old vent systems Ф 100 external diameter, air-flow is more unimpeded.Accordingly, butterfly valve 2 adopts integrated butterfly valve, increases butterfly valve internal diameter, effectively promotes exhaust brake performance.
During concrete enforcement, butterfly valve fixed support 4 takes miniaturization, makes connection first clip 1 of supercharger outlet stressed less, effectively extends this place first clip 1 life-span, reduces herein because clip lost efficacy the gas leakage risk brought.
In order to promote the compensation ability of exhaust compensator 5, effectively reduce the impact of vibration to SCR case 9, exhaust compensator 5 more easily assembles, and the life-span is longer, and taking increases the length of compensator flexible pipe 5-1, adds the effective length of collapsible tube portion.
To the structure of SCR case band band 7, replace original 6 semi-circular band forms by 2 overall band forms, under the prerequisite that constant and cost does not increase in band reliability, reduce the assembling of band, dismounting intensity.The same with SCR case 9, SCR case band band 7 adopts stainless steel material, make SCR case band band 7 and SCR case 9 overall appearance more good-looking, more aobvious class, integrality is stronger.
After adopting the utility model, engine supercharger outlet directly connects butterfly valve, greatly reduces the distance between butterfly valve and pressurized machine.Adopt integrated butterfly valve, increase butterfly valve internal diameter, promote exhaust brake performance.Add the length of flexible pipe live part, promote the compensation ability of exhaust compensator, effectively reduce the impact of vibration to SCR case.Whole like this pipe-line system trend is milder, and flex point is less, and it is more reasonable to arrange, air-flow is more smooth and easy; System back pressure is lower, effectively reduces oil consumption.Pipe-line system part kind is less, and cost is lower, and reduces assembling intensity, can improve efficiency of assembling, keeps in repair also more convenient.
