Umlomo wombhobho izifutho - futhi isiqu kudivayisi

Izifutho umlomo wombhobho - kukhona imishini yakhelwe fafaza injector amafutha kanye diesel. Supply uphethiloli noma diesel uma wenziwa khona ngaphansi kwengcindezi okusezingeni eliphezulu. Ngokuphawulekayo, ngo-likaphethiloli izinjini ukhiqiza atomization ukucindezela 3-5 izikhathi eziphindwe, ngesikhathi udizili umjovo Kwenziwa at 1000-1200 atm.

Kuqakatheke ngani?

Le nto yenza imisebenzi eminingana e uhlelo uphethiloli supply. Okokuqala, emashalofini liyinike abantu isilinganiso esifanele fuel ukuze injected. Okwesibili, umlomo wombhobho sprayer (KAMAZ-5460 kuhlanganise) enze umsebenzi ukulawula nokupheka fuel jet. Futhi okwesithathu, idivayisi ehlukanisa uqobo kusukela uhlelo umjovo we egumbini injini amandla omlilo.

Ngokuvamile, yesimanje udizili spray Imibhobho esemzimbeni aqukethe isiteshi esisodwa noma ezimbili (Imibhobho esemzimbeni), okuyothi fuel ihlinzekwa okukhishwayo futhi kamuva wafutha ekamelweni amandla omlilo. nto qualitative kufanele uhlinzeke bushelelezi Isigaxa emise spray ketshezi.

zinhlobo

Okwamanje kunezinhlobo ezimbili kuphela izinhlobo izindlela:

• kudivayisi Pin.
• Multijet (besshtiftovye).

Esimweni sokuqala, imiklamo umlomo wombhobho izifutho pin zisetshenziswa e vortex futhi precombustion diesel. amadivaysi Multi unomsebenzi ikakhulukazi izimoto, nge ngqo fuel injection, kuhlanganise imishini nge "Common Ryle" izinhlelo. Bobabili izindlela babe Nokho, design yabo ethile, abo isimiso yokusebenza Umsebenzi oyinhloko ayiguquki.

algorithm

Lapho spray Imibhobho esemzimbeni zisendaweni evulekile, woketshezi injected ekamelweni amandla omlilo. Kusukela ubuningi bayo kanye nekhwalithi okuphakelayo ke kuncike ezintweni eziningi kangaka, ezisukela amandla injini nesiphetho petrol. Uma sputtering kwenzeka ngokungalungile, imoto uqala ukuba ngibheme, ulahlekelwe umfutho futhi ngaleyo ndlela uqede ngophethiloli. Kukhona injector njalo zakoksovka engaholela ukwehluleka wako kohlelo. kudivayisi yobunzima usesimweni avaliwe, ihlinzeka kufanelekile Friend ichopho inaliti sehhashi yomzimba nebulizer. Lapho spray Imibhobho esemzimbeni zisendaweni avaliwe, lokhu inaliti aphethwe isiphethu ekhethekile lapho enza izinto Ukuvalwa Isigaxa zedivayisi. Futhi uzinake ukuthi ohlelweni umjovo "Common Ryle" esikhundleni isiphethu ingcindezi isicelo uketshezi oluvutha kalula kakhulu.

Ngaphambi fuel ifinyelela egumbini amandla omlilo, it is akhishwa ukuze umlomo wombhobho, bese sidlula iziteshi ekhethekile ngaphakathi atomizer (esikhuluma ngawo okukhulunywe ngaye esethulweni). Kancane kancane, nophethiloli is injected idivayisi, lapho ingcindezi ekhiqizwa ohlelweni. Njengoba nje ukubaluleka ifinyelela ukubaluleka ofiselekayo, inaliti entwasahlobo umlomo wombhobho kuvula kanye nophethiloli umjovo inqubo iqala isilinda. Lapho induku ukuvula ugijimela idivayisi ngaphakathi umhlahlandlela wesiteshi ku injector izindlu.
