According to the above scheme, the forward and backward three-way catalyst is ceramic honeycomb block.
The beneficial effects of the present invention are: the present invention provides a kind of exhaust system applied to electrothermic type hybrid vehicle,
Traditional silencer is eliminated in the exhaust system, and three-way catalytic converter and silencer are integrated into three-way emission control and eliminated the noise
Device is allowed to not only have the function of three-way catalytic converter, is normally carried out purification to vehicle exhaust, and have certain noise elimination
Function acts in conjunction with the noise elimination of heat and power system itself, replaces the silencer in conventional exhaust systems, can not only make exhaust system
Structure is simple, arrangement is convenient, it is ensured that the back pressure of the exhaust system will not have greatly increased compared with conventional exhaust systems；
After heat and power system is arranged in three-way emission control silencer, not only heat and power system influences the temperature that three-element catalytic reacts
The energy for being preferably minimized, and heat and power system effective use vehicle exhaust being made to release in redox.
Detailed description of the invention
Fig. 1 is the rough package drawing of one embodiment of the invention.
Fig. 2 is the structural schematic diagram of the three-way emission control silencer of one embodiment of the invention.
Specific embodiment
For a better understanding of the invention, the invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of exhaust system applied to electrothermic type hybrid vehicle, including exhaust manifold 1, close idol are urged
Change device 2, three-way emission control silencer 3 and heat and power system 4, it is net that close even catalyst converter, three-element catalytic are successively laid on exhaust manifold
Change silencer and heat and power system, forms a concatenated gas exhaust piping.
The exhaust gas of engine discharge flows through close even catalyst converter by exhaust manifold, and close idol catalyst converter carries out oxygen to the HC in tail gas
Change and purify and inhibit the oxidation reaction of CO, on the one hand can protect excessive heat that catalyst is not released by CO oxidation reaction by
On the other hand damage can be such that CO aoxidizes in the three-way emission control silencer in downstream and release heat to guarantee the normal work of catalyst converter
Temperature required for making.Close idol catalyst converter master is to solve HC emission problem when engine cold-start, it can be lower
At a temperature of work.What the work of tail gas clean-up was mainly undertaken by three-way emission control silencer, tail gas passes through close even catalysis
Enter three-way emission control silencer after device, the remaining HC in tail gas, CO, NOx in three-way emission control silencer into
The redox reaction that one step carries out generates CO2, N2 and the H2O of environmental sound, and by three-way emission control silencer
Muffling unit carries out the noise elimination of the first step, and oxidation reaction can release a large amount of heat and collect for heat and power system in this step.Finally
Tail gas is discharged into atmosphere by heat and power system, and heat and power system is collected heat entrained by tail gas and is converted into electric energy confession
Automobile uses, and carries out second to tail gas by heat and power system and eliminate the noise.Due to there is no the silencer in conventional exhaust systems, although
It is mounted with heat and power system, the back pressure of the exhaust system will not vary widely.
As shown in Fig. 2, three-way emission control silencer include outer tube 5, preceding three-way catalyst 6, rear three-way catalyst 7,
Front apron 8 and rear baffle 9, forward and backward baffle interval are set in outer tube, noise elimination cavity before, during and after outer tube is divided into, first three
First catalyst is installed in preceding noise elimination cavity front end, and rear three-way catalyst installs the noise elimination cavity rear end after described, is distinguished on forward and backward baffle
Level wears preceding hush tube 14 and rear hush tube 15.
Forward and backward hush tube is the tube body of another end opening closed at one end, and preceding hush tube is arranged in the center of front apron, after
Hush tube circumferentially install by uniform intervals, and the closed end of forward and backward hush tube is located at forward and backward noise elimination cavity, and open end is respectively positioned on
Middle noise elimination cavity, forward and backward hush tube are located on the tube wall of the part of forward and backward noise elimination cavity uniformly distributed sound attenuation hole 10.
Forward and backward three-way catalyst is ceramic honeycomb block, and preceding lining is equipped between preceding three-way catalyst and outer sleeve inner wall
Pad 11 pads 12 after being equipped between rear three-way catalyst and outer sleeve inner wall, the rear end of preceding liner and the front end padded afterwards pass through
Setting element 13 is connected with outer tube.
After vehicle exhaust is entered by the entrance of three-way emission control silencer, air-flow is by flowing through first three after expansion enlargement of pipe
First catalyst carries out first time catalytic purification to the HC in tail gas, CO, NOx, and the gas after being cleaned is by preceding noise elimination tube wall
Noise elimination cavity in sound attenuation hole entrance, gas wears the aperture on noise elimination tube wall into rear noise elimination cavity after noise elimination after passing through, and rear hush tube is
The six roots of sensation is distributed on rear baffle with 60 ° of angle, since rear hush tube is multiple and uniformly distributed, the speed of the gas after making noise elimination
It is distributed relatively uniform, is conducive to rear three-way catalyst to second of catalytic purification of tail gas.In this way, vehicle exhaust is by twice three
First catalytic purification and the outlet discharge by collapsible tube by three-way emission control silencer later of eliminating the noise twice, into following heat
Electric system.
