Catalytic Converter

Peb txoj kev catalystyog qhov tseem ceeb tshaj plaws sab nraud purification ntaus ntawv ntsia rau hauvtsheb tso qhov system.Nws yog thaum kawg sintered los ntawm cov txheej txheem tshwj xeeb txheej nrog hlau los yog ceramic li cov cab kuj, nws tus kheej-ua tsis tshua muaj lub ntiaj teb coupling oxide ua auxiliary tivthaiv thiab ib tug me me ntawm precious hlau.Cov khoom no tsis haum rau kev txo qis.

Cov catalyst tau siv tag nrho cov kev sib koom ua ke ntawm cov hlau muaj txiaj ntsig thiab tsis tshua muaj lub ntiaj teb coupound oxide, nyob rau hauv kev cuam tshuam ntawm Carbon Oxide (CO), Hydrocarbon (HC) thiab Oxynitride (Nox) nyob rau hauv cov roj av ntawm autos yog oxidized thiab deoxidized.Ua li no, peb cov pa phem tau hloov mus rau carbon dioxide (CO2), H2O thiab Nitrogen uas tsis muaj teeb meem rau huab cua.

Tom qab 100 teev ntawm lub rooj ntev zaum kev laus sai nyob rau hauv lub tsheb engineering department ntawm Tsinghua University, cov fractional conversion tus nqi ntawm CO, HC thiab Nox yog 96.3%, 94% thiab 90.5% feem.Qhov qis tshaj qhov pib kub ntawm cov catalyst yog 235 ℃, 272 ℃ thiab 230 ℃ ℃ uas tau nce los ntawm 45 ℃, 53 ℃ thiab 40 ℃ feem, piv nrog cov catalysts tshiab tom qab kev laus cov tshuaj tiv thaiv thiab cov laus coefficient yog 1.2 raws li.Tom qab kuaj ntawm autos, nws tau ua pov thawj tias tau ntsib EuⅡEmission Standard.

Nrog rau kev tswj hwm ntawm Eu Ⅲ Emission Standard thiab Eu Ⅳ Emission Standard nyob rau hauv Tuam Tshoj, Tuam Tshoj tau optimized cov khoom xyaw thiab tsim ib tug series ntawm catalysts tshiab nrog qis intial ignition kub, siab conversion efficiency thiab siab dua resistant index nyob rau hauv sintering thiab ces thov rau lub National Patent. rau invention.Kev hloov pauv ntawm cov cav tov raws li CCC + UCC lossis UCC Program ua kom muaj cov khoom siv roj av kom tau raws li Eu Ⅲ Emission Standard thiab EU Ⅳ Emission Standard.Nyob rau hauv 2006, cov khoom xyaw ntawm tus Tsov tus tw roj tau soj ntsuam nyob rau hauv lub teb chaws zoo soj ntsuam chaw ntawm autos thiab cov cotents ntawm CO, HC thiab Nox yog 1.0g/km, 0.6g/km thiab 0.08g/km raws li, uas tau ntsib Eu Ⅲ Emission Standard.
