Abstract
The utility model discloses an exhaust system of a vehicle positioned at the bottom of the vehicle, comprising a front exhaust pipe, a purifier, an auxiliary silencer and a pipeline connection of a middle exhaust pipe and a main silencer in sequence. The utility model is characterized in that two main silencers are connected in parallel behind the middle exhaust pipe and arranged symmetrically at the two sides of the vehicle body, and a metal flexible tubing is positioned on the front exhaust pipe to facilitate connection and vibration damping. Since two identical main silencers are arranged at the two sides of the vehicle body, the silencing capacities are divided which reduces the cross section area and the length of a single silencer and requires less arrange space in vertical direction. In addition, the utility model makes the most use of the space available on the vehicle floor and realizes the required silencing capacity to fulfill the pre-determined silencing ability. Besides, the exhaust system has the advantages of enabling to reach the silencing capacity of over 40 decibels, control the exhaust back pressure of the supercharged engine below 50 KPa effectively and ensure the power loss less than 4%, which meets the decomposing noise demand of the exhaust system when a whole car in motion generates the noise of up to 71 decibels.
Description
Technical field
The utility model relates to a kind of exhaustion system for automobile, especially relates to a kind of car exhaust emission suction system.In this system, a cleaner, secondary noise silencer and two identical main mufflers are housed from the exhaust steam passage that driving engine is discharged.
Background technology
Usually, in the unit of exhausting waste gas structure that vehicle is equipped with, from driving engine, arrange a catalyzed conversion cleaner, a secondary noise silencer and a main muffler successively, each adjacent component interconnects with the minor diameter freeing pipe.Wherein, catalytic convertor is used for purifying exhaust air, and secondary noise silencer and main muffler are used for reducing exhaust gas pressure and exhaust roar.Secondary noise silencer is mainly used in the problem that solves main muffler acoustical absorptivity deficiency under the very long situation of passage.Main muffler generally has heavy in section area and the short urceolus of length.In order to realize enough acoustical absorptivitys, the sectional area of main muffler is inevitable big, thereby size is big, therefore, this has just limited main muffler and must will be arranged in the enough big floor space, and this just makes vehicle rear must provide enough big luggage space in vertical direction.And,, will be difficult to provide enough big arrangement space for guaranteeing traveling comfort and the enough big space of taking at the rear portion of luxury car.
Along with more and more higher to the requirement of car load traveling comfort, this has just proposed more exacting requirements to the car load noise, thereby the noise elimination of exhaust muffler is required also more and more higher, and the dynamic property that can not sacrifice car load is simultaneously fallen.The car load crossing ability noise that can reach at present is 74 decibels, and the car load crossing ability noise of implementation is less than 71 decibels requirement and does not sacrifice the car load dynamic property simultaneously in the coming years for Europe, just require exhaust system must drop to below 65 decibels to its contribution rate.This also just has higher requirement to the design of exhaustion system for automobile.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the weak point that existing exhaustion system for automobile dynamic property and arrangement space are taken into account, and provides a kind of dynamic property of not sacrificing car load, and arrangement space a kind of exhaustion system for automobile reasonable, simple in structure.This exhaust system can satisfy engine back pressure requirement and loss in efficiency requirement simultaneously and reach higher sound deadening capacity.
The utility model is to solve the problems of the technologies described above to adopt following technical scheme: a kind of exhaustion system for automobile, be installed in the vehicle bottom, and comprise that the preceding pipe of exhaust, cleaner, secondary noise silencer, exhaust intermediate pipe and main muffler order pipeline are connected.It is characterized in that: two main mufflers in parallel behind the exhaust intermediate pipe are symmetrically distributed in the car body both sides.
For ease of connecting and vibration damping, the rich property pipe of a metal is set on the pipe before exhaust.
Two main mufflers in parallel behind the described exhaust intermediate pipe are to manage after with Y-piece threeway connection exhaust behind the exhaust intermediate pipe, connect two main mufflers again.
Pipe, secondary noise silencer, exhaust intermediate pipe and main muffler place are provided with suspension hook before exhaust, and the realization exhaust system is captiveed joint with vehicle.
Good effect of the present utility model is and since adopt the noise elimination capacity cut apart after, arrange two identical main mufflers in the both sides of car body, this just makes single noise silencer all reduce on sectional area and length, in vertical direction, the installing space that needs is less.Can rationally utilize the available space of vehicle floor, the requirement of the noise elimination volume that the satisfied again simultaneously acoustical absorptivity of subscribing is required.Adopt the rich property pipe of metal, the transfer of vibration of well having isolated driving engine is to exhaust system, thereby reduced vibration noise.In addition, pipe dwindles caliber after the exhaust simultaneously, has also just increased divergence ratio, has also improved sound deadening capacity.
Test shows, adopt the exhaust system of this structure can reach greater than the sound deadening capacity more than 40 decibels, can control exhaust back pressure below 50Kpa by actv. for blow-fed engine simultaneously, the firm power loss has been satisfied car load crossing ability noise and has been reached 71 decibels of resolution noise requirements to exhaust system less than 4%.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
