Chii chinonzi cetane number?
Imwe yemhando huru yemhando yepamusoro yemafuta edhiziri ndiko kuramba kwayo kuzvibatidza. Ndiyo parameter iyi inotsanangurwa uchishandisa nhamba yecetane. Mune mamwe mashoko, nhamba yecetane yemafuta edhiziri inoratidza nguva yenguva iyo mvura inopinda muhumburumbira isati yatungidza. Iyo yakakwirira nhamba yecetane, nguva shoma inotora kupisa. Saizvozvowo, iyo inokurumidza injini inotanga uye nguva shoma inotora iyo inonzi "white utsi".
Usakanganwa kuti yakakwirira yecetane nhamba parameter inokanganisa kukurumidza kwekushanda kwechikwata chemagetsi chemotokari uye inoita kuti ive yakarongeka yehukuru hune simba.
Sei uchiziva nhamba yecetane?
Kuziva iyo cetane nhamba parameter, zvinokwanisika kuona dhigirii rehushamwari hwezvakatipoteredza hwemafuta, nekuti kuumbwa kwehydrocarbon kunokanganisa kugona kwemvura kuzvipisa.
Semuyenzaniso, makemikoro ane parafini anogona kupfuta kupfuura mahydrocarbon anonhuwirira. Saizvozvo, iyo isinganyanyi kunhuhwirira ma hydrocarbons mukuumbwa kwemafuta, iyo yakakura iyo cetane nhamba parameter.
Kana iyo nhamba iri mubvunzo mumafuta edhiziri isingasviki makumi mana, ipapo injini yemotokari ichashanda pamuganho wekugona kwayo. Kazhinji kazhinji mumodhi yakaoma kudaro pane kugogodza kwakagomara pakusaita, uye kune zvakare nekukurumidza kupfeka kwese zvikamu zvemashini.
Ndezvipi zviyero zvinogamuchirwa munyika dzeEU, uye ndedzipi muRussia?
Nhamba yepamusoro yecetane haisi chiratidzo chepamusoro-soro yemafuta. Iko kukosha kwakaringana kuri muchikamu kubva pamakumi mashanu kusvika makumi matanhatu. Aya maitiro akajairwa nemafuta anokurudzirwa kumota dzine injini yeEuro 50.
Kana kukosha kwenhamba yecetane ichipfuura miganhu inoratidzwa kumusoro, ipapo mafuta anogona kunzi "supersaturated". Ndiko kuti, kuwedzera kwega kwega kunotevera kweparameter hakuzoiti zvine musoro.
Maererano nezvinodiwa zveGOSTs dzomumba, kukosha kwenhamba yecetane inofanira kuva inenge 45. Iyi muganhu ndiyo yakaderera inobvumirwa kukosha. Zvinoenderana nezviyero zvenyika dzeEU, iyo yakaderera chikumbaridzo iri panosvika makumi mana nemasere.
Nzira yekuwedzera sei kukosha kwenhamba yecetane?
Ehe, kunaka kweinjini yedhiziri kunokanganisa kwete chete nenhamba yecetane. Dambudziko rekuvandudza kunaka kwemafuta edhiziri rinoramba riri rimwe revanotyaira motokari. Haisi chakavanzika kuti vazhinji vekunatsa kwenyika vari kuyedza kugadzira mafuta ane cetane nhamba kukosha pamuganho wakaderera unobvumidzwa nezviyero.
Kuti uwedzere nhamba yecetane, zvinodikanwa kushandisa yakakosha cetane correctors inogona kubhadhara zvinhu zvisipo.
Zvigadzirwa zverudzi urwu zvinokanganisa kuvandudzwa kwekupisa kwehuni, uku uchiona kusarwadza kwekutanga kweinjini kunyangwe mumamiriro ekupisa kwakashata. Uye zvakare, zvinowedzera zvinokanganisa kushanda kweinjini, zvichiita kuti iite mushe, pamwe nekuderedza kuburitsa kwemhepo uye kuderedza injini ruzha.
