Ulwelo lwe-urea yemoto yasebusika luya kuba ngumkhenkce? Kuthekani ngokukhenkceza? Ngaba uyafuna ukongeza i-antifreeze yobushushu obuphantsi urea?
Ngokukhawuleza xa iqondo lokushisa lihla ebusika, abaninzi abanini beemoto, ngokukodwa emantla, baya kuba nexhala malunga nokukhenkceza kwetanki ye-urea, baya kubuza ukuba i-urea yemoto iya kukhenkceza, indlela yokuyikhenkceza, nokuba ukongeza umnini-mhlaba ubushushu obuphantsi. urea kunye nezinye iingxaki, kwaye abanye abanikazi beemoto batshintshe ngokuthe ngqo isisombululo se-urea esiqhelekileyo kunye nesisombululo se-urea -35 ° C, becinga ukuba oku kulula, enyanisweni, akunjalo. Ayibizi mali kuphela kodwa iyonakalisa ngokulula inkqubo yonyango lwasemva kwesithuthi. Ngoku makhe sandise ingqiqo esisiseko.
Kutheni ukongeza isisombululo se-urea?
Yintoni embi ngokungongezi?
Into ebizwa ngokuba yisisombululo se-urea yemoto, eyaziwa ngokuba yi-diesel exhaust treatment liquid, ibhekisela kwisisombululo se-urea kunye ne-urea yoxinaniso lwe-32.5% kunye ne-solvent yamanzi e-ultra-pure, kunye nezinto zayo eziluhlaza ziyi-crystals ze-urea kunye ne-ultra-pure water. Ifakwe kwi-tank ye-urea, xa umbhobho wokukhupha ufunyaniswa une-nitrogen oxide, itanki ye-urea ikhupha ngokuzenzekelayo isisombululo se-urea yesithuthi, kunye neempendulo ezimbini ze-REDOX zenzeke kwi-tank ye-SCR yokusabela, ukuvelisa i-nitrogen engenazo ukungcola kunye nokukhutshwa kwamanzi, ukunciphisa izinto ezikhutshwayo.
Umgaqo wokusebenza kwenkqubo ye-SCR: Ngokuthandwa kweemoto zesizwe ezine, zesizwe ezintlanu, kwaye kamva iimoto ezintandathu zelizwe, i-urea yeemoto inokutshiwo njengesongezo esibalulekileyo se-SCR, kwaye iyimveliso ebalulekileyo yezithuthi zedizili ezifana neelori kunye neebhasi. ukuhlangabezana nemigangatho yesizwe emihlanu nemithandathu ekhutshwayo.
Ukungafaki isisombululo se-urea ixesha elide, okanye ukusebenzisa amanzi ahlambulukileyo okanye amanzi ompompo endaweni yoko, kuya kubangela umonakalo omkhulu kwi-nozzle ye-urea kunye nenkqubo yonke yasemva kokunyanga. Ukwazi ukuba ukutshintshwa kwe-nozzle ye-urea ngokuqhelekileyo ngamawaka e-yuan, inkqubo yonke idinga i-30,000 ukuya kwi-50,000 ye-yuan.
Yintoni -35℃ isisombululo se-urea yesithuthi?
Ngaba uyafuna ukongeza isisombululo se-urea sobushushu obuphantsi?
Isisombululo se-urea yesithuthi esichazwe ngamazwe amane esizwe imigangatho yokukhupha imigangatho emihlanu iqala ukukhenkceza kwiqondo lokushisa eliqhelekileyo elingaphantsi kwe-11 ° C. Abavelisi ngabanye basebenzisa izongezo (i-ethanol okanye i-ethylene glycol) ukunciphisa indawo yokukhenkceza ye-urea yemoto, ukuze bafezekise injongo yokunqanda ukukhenkceza. Nangona kunjalo, i-ethanol kwi-additives iyatsha kwaye iqhume, kwaye umbhobho wokukhupha isithuthi ukwiqondo lokushisa eliphezulu, ukuba i-concentration ye-ethanol iphezulu kakhulu, iya kubangela umonakalo kumbhobho wokukhupha. Ngaphantsi kweemeko ezithile zokushisa, i-ethylene glycol iya kuvelisa izinto ze-asidi, eziza kubangela ukubola kwipayipi yokukhupha kwaye kubangele ukuvuza. Ngoko ke, akukho mfuneko yokusebenzisa into ebizwa ngokuba yi--35 ° C isisombululo se-urea yemoto, kwaye okona kubaluleke kakhulu, isisombululo se-urea yemoto -35 ° C malunga ne-40% ebiza ngaphezu kwesiqhelo kwimarike.
Ngaba isisombululo se-urea siyaba ngumkhenkce ebusika?
Kuthekani ukuba ndiyagodola?
Ngaba isisombululo se-urea siyaba ngumkhenkce ebusika? Kuthekani ukuba ndiyagodola? Enyanisweni, ezi ngxaki, abavelisi kudala beqwalasela, ngokubanzi kufuneka ukuba i-antifreeze inguqu esemantla ye-SCR yesithuthi ixhotyiswe nge-urea tank nyibilikisa umsebenzi wokufudumeza, xa ubushushu bamanzi e-injini bufikelela kuma-degrees angama-60, ubushushu bolwelo lwe-urea bungaphantsi kwe-5 degrees. I-Celsius, ukusuka kwimpompo ye-injini ukuya kwisipholileyo se-injini ye-urea iya kuvula ukuhamba komjikelezo, ukuze kunyibilike icrystallization yolwelo lwe-urea kwitanki ye-urea.
Ekubeni i-SCR idinga iqondo lobushushu lokukhupha i-injini ukuze ifikelele ngaphezu kwe-200 ° C ukuze ingene emsebenzini, ulwelo lwe-urea aluyi kutshizwa kwiqondo lobushushu eliphantsi, ukuze kunikwe ixesha elaneleyo lolwelo olunyibilikisiweyo lwe-urea.
Ngoko ke, akukho mfuneko yokukhathazeka malunga nokuba isisombululo se-urea siya kubanda, kunye nendlela yokwenza emva kweqhwa. Ukongezelela, nakwiindawo ezibanda kakhulu, akukho mfuneko yokongeza into ebizwa ngokuba yisisombululo se-urea ephantsi.
