Abstract
The utility model discloses a ternary catalytic converter, comprising a tube and purificant for ternary catalysis in the tube, wherein the front end and the back end of the tube are respectively arranged with a connection flange by an end cover with a center through-hole and a gasket layer is arranged between the purificant and the tube. The ternary catalytic converter is arranged behind an air vent of an engine. Compared with the prior technique, the ternary catalytic converter increases the exhaust gas conversion efficiency when starting the engine, in addition, the purificant for ternary catalysis is prevented from being scraped when the engine exhaust pipe is damaged and the utilization rate of the rare metal is increased.
Description
Technical field
The utility model relates to the engine tail gas purification equipment technical field, particularly a kind of three-way catalytic converter that is contained on the engine exhaust pipeline.
Technical background
Existing three-way catalytic converter all is that purifying agent is contained in neutral position in the engine exhaust pipe body, is a part of engine exhaust pipe assembly, and is inseparable with other parts.There is following problem in the engine exhaust pipe of this band three-way catalytic converter: cause related the scrapping of purifying agent that is worth expensive three-element catalytic when 1, outlet pipe damages; 2, the purifying agent of three-element catalytic is far away apart from motor, and when engine cold-start, the time that reaches its initial temperature of bringing into play catalysis is longer, and its efficient to the engine exhaust conversion is low before the engine cold-start.
Summary of the invention
A kind of can being contained on the engine exhaust port to closer distance and the three-way catalytic converter that can be connected of providing to be solved in the utility model with tool outlet pipe convenience.
In order to address the above problem, this three-way catalytic converter, include body and be contained in the purifying agent that is used for three-element catalytic in this body, described body front end is connected with a front cover with central through bore, the front end of this front cover and one are connected to an adpting flange, the rear end of described body is connected with a rear end cover with central through bore, and the rear end of this rear end cover and one are connected to an adpting flange, between described purifying agent and the described body laying are housed.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, owing to this three-way catalytic converter directly can be connected with engine exhaust outlet tracheae by adpting flange, therefore, the catalyzed conversion function of this three-way catalytic converter can be when engine cold-start, started fast, thereby the waste gas transformation efficiency of engine cold-start can be improved.
2, owing to be equipped with adpting flange in the front-end and back-end of this three-way catalytic converter body, this three-way catalytic converter is connected with outlet pipe by adpting flange, therefore, when the outlet pipe silencing apparatus damages, can reduce the loss that three-way catalytic converter is together scrapped.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
This three-way catalytic converter shown in Figure 1 is made of front end flange 1, the front cover 2 with central through bore, liner 3, body 4, purifying agent 5, the rear end cover 6 with central through bore and back end flange 7.The wherein front end of the central through bore edge of front end flange 1 and front cover 2 welding, the rearward end of front cover 2 is welded on outside the front end of body 4, the rear end outside weld of body 4 is connected to the front end of rear end flange 6, the rearward end of back end flange 6 is welded on the central through bore edge of back end flange 7, purifying agent 5 is contained in the inside of body 4, between purifying agent 5 and body 4 liner 3 is housed.
