Cov teeb meem tshwm sim nrog Automobile Exhaust Systems

1. Thaum lub sij hawm siv lub tsheb, vim muaj kev ua txhaum ntawm cov khoom siv roj, lub tshuab hluav taws xob, thiab lwm yam, lub cav overheats thiab backfires, ua rau lub sintering thiab tev tawm ntawm peb-txoj kev catalytic converter cab kuj thiab nce pa tawm tsis kam; 2. Vim yog siv cov roj los yog cov roj lubricating, cov catalyst yog tshuaj lom thiab nws cov haujlwm txo qis, cov catalytic conversion efficiency cuam tshuam, thiab sulfur thiab phosphorus complexes thiab sediments yog generated nyob rau hauv peb-txoj kev catalytic converter, uas nyob rau hauv lem deteriorates lub kev ua tau zoo ntawm lub tsheb, ua rau txo qis kev ua haujlwm, kev siv roj ntau ntxiv, thiab ua rau cov pa phem phem.
