ʻO ka inoa ʻepekema o ka urea kaʻa ʻo ia ka wai hoʻomaʻemaʻe hoʻoheheʻe diesel, ka mea maʻamau i hoʻohana ʻia i nā ʻenekini diesel.He wai ia i hoʻohana ʻia i ka ʻenehana SCR e hōʻemi i ka pollution nitrogen oxide i ka pauku diesel.He 32.5% ka urea maʻemaʻe kiʻekiʻe a me 67.5% ka wai deionized.ʻO ke kumu e hoʻemi i nā mea haumia nitrogen oxide i hoʻokuʻu ʻia e ka ʻenekini diesel, no laila ua ʻike ʻia ʻo ia ʻo Euro IV maʻamau ma Kina.

ʻOkoʻa ka mālama ʻana i nā kaʻa ke koho ʻia nā ʻano hopena urea ʻokoʻa.Ke 'a'ole lawa ka ma'ema'e o ka ho'onā urea i wae 'ia a aia nā mea haumia e like me nā ʻāpana a me nā ion metala kaumaha, e hoʻopilikia nui ia i ka nozzle, kānana a me nā ʻāpana ʻē aʻe o ka ʻōnaehana SCR kaʻa, a lawe mai i nā poho waiwai ʻole.Inā ʻaʻole kiʻekiʻe ka hoʻohui ʻana o ka hopena urea haʻahaʻa, a aia nā metala kaumaha a me nā mea kemika ʻē aʻe, e hana ia me ka catalyst e hōʻemi i ka hopena o ka hoʻololi ʻana o ka huelo kinoea, a i ʻole nalo i kāna hana.

Loaʻa i ka ʻōnaehana SCR ka pahu urea (hoʻopiha ʻia me ka wai lapaʻau hoʻopau diesel) a me SCR catalytic reaction tank.ʻO ke kaʻina hana o ka ʻōnaehana SCR: i ka wā e loaʻa ai ka nitrogen oxide i loko o ka paipu exhaust, e hoʻoheheʻe ʻia ka pahu urea i ka wai hoʻoheheʻe diesel, a ʻo ka wai hoʻomaʻamaʻa diesel a me ka nitrogen oxide e hana i ka oxidation a me ka hoʻohaʻahaʻa ʻana i ka SCR catalytic reaction tank. e hana i ka naikokene pollution-free a me ka mahu wai no ka hoʻokuʻu ʻana.

Inā ʻaʻole i hoʻouka ʻia ka wai hoʻomaʻemaʻe o ka mīkini diesel, a ʻaʻole lawa ka maʻemaʻe, a i ʻole he hoʻopunipuni ka maikaʻi, e hoʻemi koke ka mīkini kaʻa.I ka manawa like, e hoʻohaumia ʻia ka wai hoʻomaʻemaʻe kinoea huelo mīkini diesel me ka maikaʻi haʻahaʻa i ka catalyst i loko o ka tank catalytic reaction tank, e hoʻoulu ai i nā hopena koʻikoʻi.
