Cetane corrector. Momwe mungapangire mafuta a dizilo apamwamba kwambiri?
Zamkatimu
Kodi chimapangitsa kuchuluka kwa cetane ndi chiyani?
Fanizo la petulo ndi lathunthu. Monga momwe octane corrector angapangire kuchuluka kwa kuyaka kwa petulo, cetane corrector idzachitanso chimodzimodzi ndi mafuta a dizilo. Ubwino wa izi ndi:
- Kuchepetsa kwambiri mphamvu ya injini ya sooty.
- Ntchito ya injini ndi mphamvu yake yoyamba idzawonjezeka.
- Kuchedwa kwa kuyatsa kudzachepetsedwa.
- Kuchepetsa mwaye pa nozzles.
- Phokoso lotulutsidwa ndi injini lidzachepa, makamaka panthawi yozizira.
Zotsatira zake, kuyendetsa galimoto yotere kumakhala kosavuta.
Kuwotcha kwamafuta mu injini za dizilo kumatheka chifukwa cha kutentha komwe kumapangidwa ndi kuponderezedwa kwa mpweya, popeza kuyenda kwa pisitoni mu silinda kumayendera limodzi ndi kuchepa kwa voliyumu ya silinda panthawi ya psinjika. Mafuta owonjezera amabayidwa kuti aziyaka nthawi yomweyo. Pamene kuyatsa kuchedwa, zomwe zimatchedwa "kuwomba kwa dizilo" zimachitika. Chodabwitsa ichi chikhoza kupewedwa mwa kuwonjezera nambala ya cetane ya mafuta. Zizindikiro zowongolera zamafuta abwino a dizilo - nambala ya cetane mu 40 ... 55, yokhala ndi otsika (osakwana 0,5%) sulfure.
Njira zowonjezera nambala ya cetane
Opanga akuwonjezera kupanga kagawo kakang'ono ka distillate, komwe nambala yachilengedwe ya cetane imatsitsidwa. Ndi kukula kwa mowa komanso kuchuluka kwa injini za dizilo zokhala ndi mpweya wocheperako, kukulitsa ndi kugwiritsa ntchito ma cetane correctors amafuta a dizilo ndikofunikira kwambiri.
Mapangidwe a okonza cetane amaphatikizapo peroxides, komanso zinthu zomwe zili ndi nayitrogeni - nitrates, nitrites, ndi zina zotero. Kusankhidwa kumatsimikiziridwa ndi kuchuluka kwa kusavulaza kwa nthunzi ya mankhwala oterowo, kusakhalapo kwa phulusa panthawi yoyaka, ndi mtengo wotsika.
Kuwonjezeka kwa chiwerengero cha cetane kungayambitsidwe ndi zifukwa zina:
- Kutsatira mosamalitsa zosungiramo mafuta a dizilo;
- Kusungidwa kwa mafuta ochuluka kwambiri pa kutentha kochepa;
- Kusefera kwabwino;
- Kupatulapo ndi zitsulo zokhala ndi malata pa kuchuluka kwa zitsulo zomwe zimagwiritsidwa ntchito popanga akasinja ndi mapaipi amafuta a dizilo.
Mitundu yotchuka kwambiri ya cetane correctors
Eni ake odziwa zambiri zamagalimoto a dizilo amangowonjezera nambala ya cetane powonjezera zinthu monga toluene, dimethyl ether kapena 2-ethylhexyl nitrate kumafuta a dizilo. Njira yotsiriza ndiyo yovomerezeka kwambiri, chifukwa nthawi yomweyo kukana kwa magawo osuntha a injini kumawonjezeka. Komabe, bwanji kukhala pachiwopsezo ngati pali mitundu yokwanira ya ma cetane correctors omwe akugulitsidwa. Nawa otchuka kwambiri:
- Dizilo Cetane Boost kuchokera ku chizindikiro cha Hi-Gear (USA). Amapereka kuwonjezeka kwa chiwerengero cha cetane ndi 4,5 ... 5 mfundo. Kupangidwa mu mawonekedwe okhazikika, kumapereka kuwonjezeka kwa kulimba kwa injini. Imawonjezera mphamvu yoyatsira dizilo, imakulitsa mphamvu yomwe ilipo, imawongolera poyambira, imathandizira kukhazikika, imachepetsa utsi ndi mpweya. Choyipa chokha ndichokwera mtengo.
- Zotsatira AMSOIL kuchokera ku mtundu womwewo. Akulimbikitsidwa mafuta a dizilo otsika kwambiri a sulfure komanso injini ikatenthedwa ndi biodiesel. Lilibe mowa, limawonjezera mphamvu ya injini, kuchuluka kwa cetane kumafika 7 mfundo.
- Lubrizole 8090 ndi Kerobrizole EHN - zowonjezera zowonjezera za cetane, zomwe zimapangidwa ndi nkhawa yaku Germany BASF. Ku Ulaya, amalandira chiwerengero chapamwamba kwambiri kuchokera kwa ogwiritsa ntchito, koma ku Russia ndi osowa, chifukwa panthawi yozizira amawonjezera kuchuluka kwa nitrogen dioxide mu mpweya wotuluka pamwamba pa malire ovomerezeka.
- Boti zowonjezera dizilo kuchokera ku mtundu waku Germany Liqui Moly. Wotsimikiziridwa m'dziko lathu, ali ndi antibacterial ndi lubricating effect. Tikayang'ana ndemanga, Liqui Moly Liwiro Dizilo Zusatz ndi bwino, koma inu mukhoza kuyitanitsa zowonjezera m'masitolo Intaneti.
- Cetane-corrector Ln2112 kuchokera ku chizindikiro cha LAVR (Russia) - njira yabwino kwambiri yowonjezera chiwerengero cha cetane. Mbali ya ntchito - mankhwala ayenera kutsanuliridwa mu thanki nthawi yomweyo refueling.
- Russian mankhwala Zamgululi ndi wotsika mtengo. Komabe, imagwira ntchito zake bwino, zotengerazo ndizochepa (zopangidwira 50 ... 55 malita a dizilo).
