Puas yog lub diesel xav tau lub catalytic converter?

Lub luag haujlwm ntawm lub catalyst yog txo cov emissions ntawm cov pa phem, nrog rau cov emissions los ntawm ib tug diesel cav.

Tau ntau tshaj 20 xyoo, cov tuam txhab tsheb tau siv cov catalytic converters nyob rau hauv lub tshuab tso pa ntawm roj av cav. Txij li thaum lub catalytic converter yog ib qho cuab yeej siv los txo cov emission ntawm cov khoom tsis zoo rau hauv cov pa roj, nws kuj tseem siv rau hauv cov cav tov diesel. Lub cav diesel emissions kua qaub, hydrocarbons, sulfur dioxide, nitrogen oxides thiab hlau: calcium, magnesium, hlau thiab zinc vim lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab cov roj siv. Cov oxidation catalyst siv dav siv 98 feem pua ​​​​ntawm cov pa roj carbon dioxide emissions thiab ntau tshaj 80 feem pua ​​​​ hydrocarbon thiab carbon monoxide emissions. Los ntawm 2005, thaum lub Euro IV tus qauv los rau hauv lub zog nyob rau hauv lub tso pa system ntawm diesel xyaw, nws yuav tsim nyog rau nruab catalysts thiab ib tug particulate lim, tejzaum nws yuav ntxiv ib tug ntxiv catalyst rau neutralize nitrogen oxides.
