I-Cetane corrector. Indlela yokwenza uphethiloli we-diesel wekhwalithi ephezulu?
Okuqukethwe
Yini eyenza ukwanda kwenani le-cetane?
Isifaniso nophethiloli siphelele. Njengoba nje i-octane corrector izothuthukisa izinga lokushiswa kukaphethiloli, i-cetane corrector izokwenza okufanayo ngophethiloli wedizili. Izinzuzo ezingokoqobo zalokhu yilezi:
- Kunciphise kakhulu umfutho wokuphuma kwenjini ye-sooty.
- Ukusebenza kwenjini namandla ayo okuqala kuzokhula.
- Ukubambezeleka kokuthungela kuzoncishiswa.
- Inciphe kakhulu umule emibhobolweni.
- Umsindo okhishwa injini uzokwehla, ikakhulukazi lapho kubanda kuqala.
Ngenxa yalokho, ukushayela imoto enjalo kuba ntofontofo.
Ukushiswa kukaphethiloli ezinjinini zedizili kufezwa ukushisa okukhiqizwa ukucindezelwa komoya, njengoba ukunyakaza kwepiston kusilinda kuhambisana nokuncipha komthamo we-cylinder ngesikhathi sokucindezela. Uphethiloli owengeziwe uyajovwa ukuze kuqinisekiswe ukuthungela ngokuphazima kweso. Lapho ukuthungela kubambezeleka, lokho okubizwa ngokuthi "i-diesel blow" kwenzeka. Lesi simo esibi singavinjelwa ngokukhulisa inombolo ye-cetane kaphethiloli. Izinkomba zokulawula zekhwalithi enhle kaphethiloli we-diesel - inombolo ye-cetane ebangeni lama-40 ... 55, enokuqukethwe okuphansi kwesibabule (ngaphansi kuka-0,5%).
Izindlela zokwandisa inombolo ye-cetane
Abakhiqizi bakhulisa ukukhiqizwa kwengxenyana ye-distillate ephakathi, lapho inombolo ye-cetane yemvelo yehliswa khona. Ngokukhula kokusetshenziswa kanye nenani lezinjini zedizili ezinezinga elincishisiwe lokukhipha umoya, ukuthuthukiswa kanye nokusetshenziswa kwama-corrector e-cetane asebenzayo kuphethiloli wedizili kubaluleke kakhulu.
Ukwakhiwa kwama-correctors e-cetane kuhlanganisa ama-peroxides, kanye nezinto eziqukethe i-nitrogen - i-nitrate, i-nitrites, njll. Ukukhethwa kunqunywa izinga lokungabi nabungozi kwe-vapor yalezi zinhlanganisela, ukungabi khona komlotha ngesikhathi somlilo, nezindleko eziphansi.
Ukwanda kwenombolo ye-cetane kungabangelwa ezinye izici:
- Ukulandelwa okuqinile kwezimo zokugcina udizili;
- Ukugcinwa kwe-fuel density ephezulu emazingeni okushisa aphansi;
- Ukuhlunga kwekhwalithi;
- Okuhlukile yinsimbi enani lezinsimbi ezisetshenziselwa ukwakha amathangi namapayipi kaphethiloli kadizili.
Imikhiqizo ethandwa kakhulu ye-cetane correctors
Inani labanikazi abanolwazi lwezimoto zikadizili ngokuzimela bakhulisa inombolo ye-cetane ngokungeza izinto ezifana ne-toluene, i-dimethyl ether noma i-2-ethylhexyl nitrate kuphethiloli wedizili. Inketho yokugcina iyona eyamukelekayo kakhulu, ngoba ngesikhathi esifanayo ukumelana kwezingxenye ezihambayo zenjini kuyathuthukiswa. Kodwa-ke, kungani ubeka engcupheni uma kunenani elanele lemikhiqizo yezilungisi ezikhethekile ze-cetane ezithengiswayo. Nazi ezidume kakhulu:
- I-Diesel Cetane Boost kusukela kuphawu lokuhweba lwe-Hi-Gear (USA). Inikeza ukwanda kwenombolo ye-cetane ngo-4,5 ... amaphuzu angu-5. Ikhiqizwe ngendlela egxilile, inikeza ukwanda kokuqina kwenjini. Ithuthukisa ikhwalithi yokuthungela kukadizili, ikhulise amandla atholakalayo, ithuthukise ukuqala, ishelela ukungenzi lutho, inciphisa intuthu nokukhipha umoya. Okubi kuphela yinani eliphezulu.
- I-AMSOIL kusukela kumkhiqizo ofanayo. Kunconyelwe amafutha edizili esibabule asezingeni eliphansi kakhulu nalapho injini ibaswa nge-biodiesel. Ayiqukethe utshwala, inyusa amandla enjini, ukwanda kwenombolo ye-cetane kufinyelela amaphuzu ayi-7.
- I-Lubrizol 8090 ne-Kerobrizol EHN - izithasiselo zokulungisa i-cetane, ezikhiqizwa yi-BASF yaseJalimane yokukhathazeka. EYurophu, bathola izilinganiso eziphakeme kakhulu ezivela kubasebenzisi, kodwa azivamile eRussia, ngoba ngesikhathi sokuqala okubandayo bandisa inani le-nitrogen dioxide emagesi okukhipha ngaphezu kwemingcele evumelekile.
- Isengezo sikadizili wesikebhe kusuka kumkhiqizo waseJalimane i-Liqui Moly. Eqinisekisiwe ezweni lakithi, inomphumela wokulwa namagciwane kanye nokugcoba. Uma sibheka ukubuyekezwa, i-Liqui Moly Speed Diesel Zusatz ingcono nakakhulu, kodwa ungakwazi kuphela uku-oda isengezo esinjalo ezitolo ze-inthanethi.
- I-Cetane-corrector Ln2112 kusukela kuphawu lokuhweba lwe-LAVR (eRussia) - indlela yesabelomali kakhulu yokwandisa inombolo ye-cetane. Isici sohlelo lokusebenza - umkhiqizo kufanele uthele ethangini ngokushesha ngaphambi kokugcwalisa i-refueling.
- Isidakamizwa saseRussia I-BBF ishibhile. Kodwa-ke, yenza imisebenzi yayo kahle, ukupakishwa kuphela kuncane (yenzelwe ama-50 kuphela ... 55 amalitha we-diesel fuel).
