Technical field
The utility model relates to motor-vehicle tail-gas to be administered and environmental protection technical field, in particular, relates to a kind of on-line evaluation device that is used for motorcycle exhaust exhaust system catalyzer.
Background technology
Be used for the general synthetic gases that adopt of evaluating apparatus of the catalyzer of motor-vehicle tail-gas more, be about to CO
2, CO, NOx etc. constitute the main constitutional chemistry gas of motor-vehicle tail-gas, by the synthetic analog gas of certain physical control structure, carries out the evaluation experimental of performances such as catalyst activity, permanance according to certain ratio.
The analog gas appraisement system advantage of synthetic is: performances such as activity that can more accurate ground evaluate catalysts, permanance, generally be used to inquire into the theoretical question relevant with catalyst reaction mechanism, and be suitable for the laboratory study use.But the analog gas appraisement system of synthetic not only needs to dispose special source of the gas (or adopting the bottled source of the gas that regularly replaces), and requires the very strictness of flow control to gas, to satisfy the proportioning that is maintained fixed between the forming gas.Therefore, the analog gas appraisement system of synthetic not only pipeline structure and gaseous mass (or flow) operation valve piece is very complicated, and gaseous mass purity is had certain requirement.In addition, the analog gas of synthetic is not the real emission gases of motorcycle after all, and the correlated performance of the catalyzer of its sign has certain limitation.In addition, on characterization method, the analog gas appraisement system of synthetic is most to be adopted accurate and gas chromatograph complexity.Gas chromatograph not only price is more expensive, the cost height, and need very long one section equilibration time in use, therefore, gas chromatograph just is restricted at applied technical field.
The utility model content
The purpose of this utility model provides a kind of motorcycle exhaust catalyst on-line evaluation device, and this device is a kind of physical unit that can directly utilize common multifunctional engine exhaust gas analysis diagnostic equipment motorcycle catalyst effect to be carried out on-line evaluation.
The utility model motorcycle exhaust catalyst on-line evaluation device, be achieved by following technical proposals, described device comprises multifunctional engine exhaust gas analysis diagnostic equipment, adds electrothermal stove, air inlet position sampling pipe, exhaust position sampling pipe, gas direction control valve, air inlet pipeline, in line pipeline; Described air inlet pipeline connects air inlet position sampling pipe respectively, adds electrothermal stove, and bypass line, the described electrothermal stove that adds connects exhaust position sampling pipe and in line pipeline respectively, described exhaust position sampling pipe connects multifunctional engine exhaust gas analysis diagnostic equipment, and above-mentioned each pipeline is respectively arranged with gas direction control valve.
The electrothermal stove that adds described in the utility model is provided with temperature controller.Described in line pipeline is provided with flowmeter.Described multifunctional engine exhaust gas analysis diagnostic equipment can be single channel sampling or binary channels sampling.
The utility model directly adopts motorcycle emission tail gas as research object, by the gas sample thief hatch of reserving, directly utilize common multifunctional engine exhaust gas analysis diagnostic equipment to carry out the analysis and the comparison of catalyzer front and back gas componant, draw more real evaluation result.
The major advantage of the utility model evaluating apparatus: system is simple and practical, evaluation result is intuitive and reliable.The utility model evaluating apparatus does not have the distribution pipeline and the operation valve piece of complexity of the analog gas of synthetic, directly adopt motorcycle emission tail gas as the analysis and research object, directly utilize common multifunctional engine exhaust gas analysis diagnostic equipment to carry out the analysis and the comparison of catalyzer front and back gas componant, the result comes into plain view.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises multifunctional engine exhaust gas analysis diagnostic equipment 7, adds electrothermal stove 5, temperature controller (case) 6, air inlet position sampling pipe 3, exhaust position sampling pipe 8, gas direction control valve 2,4,9 and 13, flowmeter 10, air inlet pipeline 1, in line pipeline 11, bypass line 12; Air inlet pipeline 1 is connected with air inlet position sampling pipe 3 respectively, adds electrothermal stove 5, bypass line 12; Air inlet position sampling pipe 3, bypass line 12 are provided with gas direction control valve 2,13 respectively; Add electrothermal stove 5 and connect exhaust position sampling pipe 8 and in line pipeline 11 respectively, exhaust position sampling pipe 8 is provided with gas direction control valve 9; Add electrothermal stove 5 and be provided with temperature controller 6, in line pipeline 11 is provided with flowmeter 10; Exhaust position sampling pipe 8 is plugged with multifunctional engine exhaust gas analysis diagnostic equipment 7.
Air inlet pipeline 1 directly is connected on the motorcycle exhaust pipe by ring flange.During experiment, gas direction control valve 4 is opened, and gas is flowed through through pipeline the electrothermal stove that adds of catalyzer is housed, and passes through flowmeter 10 again, discharges experiment waste gas through in line pipeline 11.
As adopt single-channel multi-functional engine exhaust analyzing and diagnosing instrument, after the experiment beginning, the sampling probe with multifunctional engine exhaust gas analysis diagnostic equipment inserts air inlet position sampling pipe 3 earlier, opens gas direction valve 2, sample, analyze motor exhaust key component and feature then without catalyzer; Then, close gas direction valve 2, take out sampling probe and insert exhaust position sampling pipe 8, open gas direction valve 9, sampling analysis is through motorcycle waste gas key component and feature behind the catalyst reaction.Contrast fore-and-aft survey result draws related conclusions.
If adopt double-channel multifunctional engine exhaust analyzing and diagnosing instrument, two sampling probes can be inserted air inlet position sampling pipe 3 and exhaust position sampling pipe 8 respectively, directly detect and analyze through motorcycle waste gas key component and feature before and after the catalyst reaction, directly contrast fore-and-aft survey result draws related conclusions.
The structure of experimental stand and size be according to adding the size of electrothermal stove, and can guarantee to be convenient to the installation of motor exhaust evaluation pipeline and fix.
As when the laboratory experiment, in order to guarantee safety, in line pipeline 11 and bypass line 12 must be connected the pipelines of same inner diameter sizes to outdoor.
