Udizili ku-LPG - ubani ozuzayo ngokufakwa kwegesi enjalo? Umhlahlandlela
Ukwenyuka kwakamuva kwentengo kadizili kwenyuse inzalo ezinjinini ezisebenza ngegesi. Hlola ukuthi hlobo luni lwenguquko.
Umbono wokushisa i-LPG enjinini yedizili awumusha. E-Australia, lobu buchwepheshe busetshenziswe ezimotweni zezentengiselwano iminyaka eminingi. Ngakho, izindleko zokusebenza ziyancipha.
Esikhathini lapho intengo kadizili ilingana nentengo kaphethiloli, i-autogas refueling nayo isiqala ukwenza inzuzo ezimotweni zabagibeli zikadizili. Nokho, isimo mileage okusezingeni eliphezulu.

Amasistimu amathathu
Izinjini zikadizili zingasebenza ku-LPG ngezindlela ezahlukahlukene. Enye yazo ukuguqulwa kweyunithi ye-diesel ibe injini yokuthungela inhlansi, i.e. isebenza njengeyunithi kaphethiloli. Lolu uhlelo lwe-mono-fuel (uphethiloli owodwa) - olusebenza kuphela ku-autogas. Kodwa-ke, lokhu kuyisixazululo esibiza kakhulu, ngoba kudinga ukulungiswa okuphelele kwenjini. Ngakho-ke, isetshenziselwa kuphela imishini yokusebenza.
Isistimu yesibili i-dual-fuel, eyaziwa nangokuthi i-gas-diesel. Injini inikwe amandla ngokunciphisa ukujova kukadizili bese ifaka i-LPG. Uphethiloli wedizili unikezwa ngenani elivumela ukuvutha okuzenzakalelayo kusilinda (kusuka kumaphesenti angama-5 kuye kwangama-30), enye igesi. Nakuba lesi sixazululo ishibhile kune-monopropellant, sihlotshaniswa nezindleko ezibalulekile. Ngaphezu kokufakwa kwemboni yegesi, uhlelo lokukhawulela umthamo kaphethiloli we-diesel nalo luyadingeka.

Uhlelo lwesithathu futhi oluvame kakhulu igesi kadizili. Kulesi sixazululo, i-LPG iyisengezo kuphela kuphethiloli we-diesel - ngokuvamile ngesilinganiso: amaphesenti angu-70-80. diesel fuel, 20-30 amaphesenti autogas. Lolu hlelo lusekelwe embonini yegesi, efana naleyo esetshenziselwa izinjini zikaphethiloli. Ngakho, ikhithi yokufaka ihlanganisa i-evaporator reducer, i-injector noma imibhobho yegesi (kuye ngokuthi amandla enjini) kanye neyunithi yokulawula ye-elekthronikhi enezintambo.
Isebenza kanjani?
Umthamo omkhulu kaphethiloli we-diesel ujovwa emakamelweni avuthayo enjini, futhi ingxenye eyengeziwe yegesi ijovwa ohlelweni lokuthatha. Ukuthungela kwawo kuqalwa umthamo wokuzithungela kawoyela. Ngenxa yokwengezwa kukaphethiloli onegesi, ukusetshenziswa kukaphethiloli kadizili kuyehla, okunciphisa izindleko zikaphethiloli ngamaphesenti angaba ngu-20. Lokhu kungenxa yokuthi ukungezwa kwegesi kuvumela uphethiloli wedizili ukuthi ushise kangcono. Enjinini ye-diesel evamile, ngenxa ye-viscosity ephezulu ye-OH nomoya oweqile, ukuvutha okuphelele kukaphethiloli cishe akunakwenzeka. Isibonelo, kumayunithi anohlelo lwe-Common Rail, amaphesenti angama-85 kuphela. ingxube yamafutha edizili nomoya isha ngokuphelele. Okusele kuguqulwa kube amagesi akhipha umoya (i-carbon monoxide, ama-hydrocarbon kanye ne-particle matter).
Njengoba inqubo yokushiswa kwegesi ye-diesel isebenza kahle, amandla enjini kanye ne-torque nawo ayanda. Umshayeli angakwazi ukulawula ukushuba komjovo wegesi enjinini ngokucindezela i-accelerator pedal. Uma eyicindezela kakhulu, igesi eyengeziwe izongena ekamelweni elivuthayo, futhi imoto izohamba ngesivinini esingcono.
Bheka futhi: Uphethiloli, udizili, i-LPG - sibale ukuthi iyiphi idrayivu eshibhe kakhulu
Ukunyuka kwamandla okungafika ku-30% kungenzeka kwezinye izinjini ezine-turbocharged. ngaphezu kwamandla alinganiselwe. Ngesikhathi esifanayo, ukuthuthukiswa kwemingcele yokusebenza kwenjini akuphazamisi kabi insiza yayo, ngoba iwumphumela wokushiswa okuphelele kophethiloli. Imiphumela yokusha ethuthukisiwe kumasilinda angenayo i-carbon namaringi e-piston. Ngaphezu kwalokho, ama-valve okukhipha umoya, i-turbocharger ihlanzekile, futhi ukuphila kwama-catalysts nezihlungi ze-particle kunwetshwa kakhulu.
Kubiza malini?
E-Poland, okuvame ukusetshenziswa kakhulu amayunithi amathathu asebenza ohlelweni lwegesi kadizili. Lena i-DEGAMix ka-Elpigaz, i-Solaris ye-Car Gaz kanye ne-Oscar N-Diesel yase-Europegas.

Izintengo zokufakwa kwalaba bakhiqizi, ezenzelwe izimoto namaveni amaningi, ziyefana futhi zisukela ku-PLN 4 kuye ku-5. i-zloty. Ngakho-ke, izindleko zokuhlanganisa uhlelo lwe-LPG lwenjini ye-diesel azincane. Ngakho-ke, intshisekelo kulezi zinhlelo phakathi kwabasebenzisi bezimoto iphansi.

- Ukusebenzisa injini ngedizili negesi yemvelo kuwuhlelo olusebenza kahle kakhulu. Lokhu akugcini nje ngokusindisa izindleko zokusebenza, kodwa futhi kuhlanzekile endaweni ezungezile. Ukusebenza kahle kwenjini (ukwenyuka kwamandla netorque) nakho kubaluleke kakhulu. Ngesikhathi esifanayo, ukuqina nokuthembeka kokusebenza kwedrayivu kuphakeme, ngoba ukufakwa akuphazamisi ukusebenza kwezilawuli zezimoto. Nokho, ukufaka i-HBO enjinini kadizili kunenzuzo kuphela uma imoto inebanga elihamba phambili lonyaka futhi kungcono kakhulu ukuba ayishayele ngaphandle kwedolobha. Ukucaciswa kwalezi zinhlelo ukuthi zisebenza kahle kakhulu uma injini isebenza nomthwalo ofanayo. Ngalesi sizathu, izitshalo zikadizili ze-LPG zisetshenziswa ekuthuthweni komgwaqo.
