I-valve yenaliti yomjovo kaphethiloli ayivalwanga ngokuqinile nomzimba we-valve futhi iyabanjwa
Izimpawu zokwehluleka: isekethe kawoyela enengcindezi ephansi ayivinjiwe, injini yedizili ijikeleziswa ngemuva kokuthi isibambo sokulawula isivinini sibekwe endaweni yokuhlinzeka uwoyela, umsindo womjovo kaphethiloli womjovo kaphethiloli awuzwakali kwamanye amasilinda, kanti intuthu emhlophe ephuma epayipini lokukhipha umoya, ngakho-ke kunzima ukubamba umlilo. Lapho injini ye-diesel ivutha, ipayipi le-exhaust lisakhipha intuthu, isivinini sokuzinza asizinzile, sihambisana nomsindo ophefumulayo we-"Teng, Teng", futhi kuzwakala umsindo ongqongqozayo ngesivinini esikhulu kanye ne-throttle. Lapho izinga lokushisa lenjini ye-diesel likhuphuka, ipayipi yokukhipha ikhipha intuthu emnyama, i-injector yamafutha iyashisa, futhi umlilo "ulahlekelwa imilenze". Nqamula ipayipi likawoyela elinomfutho ophezulu wesilinda somlenze ongekho. Ipayipi le-exhaust lenjini kadizili alisakhiphi intuthu, nomsindo wokungqongqoza kwesilinda nawo uyanyamalala. Kodwa-ke, kunento yokukhipha umoya endaweni ehlangene yepayipi likawoyela elinomfutho ophezulu womjovo, futhi igwebu liyakhishwa.
Ukuhlaziywa kwembangela yokwehluleka: (1) Phakathi nenqubo yokusebenza kwenjini kadizili, uwoyela we-diesel womfutho ophezulu ompontshelwa empompini yomjovo kaphethiloli uthwala ukungcola okuthile okusemishinini, ingene kumjovo kaphethiloli futhi ibambelele endaweni yekhoni yokuvala yomzimba wevalvu yenaliti. , okubangela ukuphina, ukugoba, kanye nokuxhumana Akunzima (2) Ngenxa yokukhishwa kwegesi enomfutho ophezulu kanye nezinga lokushisa eliphezulu egumbini elivuthayo, okuhambisana nokuguguleka okuvamile kokungcola kwemishini kuphethiloli, imigodi nemigodi kuvela eringini yokuvala phakathi kwevalve yenaliti nomzimba wevalvu yenaliti, okubangela i-valve yenaliti kanye ne-valve Ukusebenza kokuvala phakathi kwemizimba kuyawohloka, futhi okwenzekayo ukuthi umthamo wokubuyisela uwoyela emgodini wokubuyisela uwoyela we-injector uyakhula. Ngale ndlela, i-high-pressure kanye ne-high-temperature gas ekamelweni elivuthayo lizongena ekamelweni lamafutha le-annular le-injector ngesikhathi sokusebenza. Ngaphansi kwesenzo sokushisa okuphezulu, i-valve yenaliti yomjovo kanye nomzimba we-valve kuyashiswa futhi kwandise futhi kulumane kuze kube sekufeni. (3) Kuningi kakhulu ukungcola kwemishini kuwoyela udizili, okuzophinde kubangele ukuthi ukungcola kungene phakathi kwevalvu yenaliti kanye nendawo ewumhlahlandlela ye-valve yomzimba bese iluma ize ife. Ngenxa yokuthi i-valve yenaliti yomjovo inamathele emzimbeni we-valve, ukusebenza kwe-atomization kawoyela we-diesel kuyancipha, isikhathi somjovo kaphethiloli sifushane kakhulu futhi sibuyela emuva kancane, okuholela esilinganisweni esifushane kakhulu sokuvutha kanye nesikhathi sokuvutha, okwenza Injini kadizili isebenza kanzima, ngakho injini kadizili ikhipha " I-Teng, i-Teng umsindo kanye nomsindo ozwakalayo wokungqongqoza wesilinda. (4) Ngoba i-valve yenaliti yomjovo ayivalwanga ngokuqinile ngomzimba we-valve noma ibambeke endaweni evulekile, igesi ephezulu yokushisa ekamelweni elivuthayo ingena ekamelweni lamafutha le-annular le-injector, Izokwenza ukuthi i-injector ishise Uma injini ye-diesel iguqulwa kulokhu isimo, umoya ocindezelwe okhiqizwe kusilinda uzongena egunjini likawoyela eliyi-annular kanye nephaseji likawoyela ngembobo yomlomo evulekile, futhi ukhishwe kuwoyela wengcindezi ephezulu. ipayipi, ngaleyo ndlela wethula ukukhishwa kwepayipi likawoyela elinengcindezi ephezulu.
