Kungani injini ye-diesel inentuthu emnyama, futhi ungayixazulula kanjani?

1

Injini kadizili intuthu emnyama inezizathu ezimbalwa.ngokwezinkinga ezivame ukuvela, ziba nazolandela izizathu:

1.inkinga yesistimu yomjovo kaphethiloli

2.Inkinga yesistimu yokushisa

3.Inkinga yesistimu yokungenisa

4.Inkinga yesistimu yokukhipha amandla

5.Abanye ngokwesibonelo inkinga yekhwalithi yedizili, inkinga ehambisana nezingxenye

Ungasiqinisekisa kanjani isizathu futhi usixazulule?

1) I-engeli engalungile yokunikezwa kukaphethiloli.I-engeli yokunikezwa kukaphethiloli kusengaphambili yenjini ye-diesel iyi-engeli ehamba phambili yokuqinisekisa ukuvutha okuphelele kukaphethiloli ngemva kokufaka isilinda.I-engeli engaphambili nayo ihlukile kumamodeli ahlukene.I-engeli engalungile yomjovo izoholela ekushisweni kukaphethiloli okunganele nokungaphelele kwenjini kadizili, okuzoholela kuntuthu omnyama wenjini kadizili.a.I-engeli yokunikezwa kukaphethiloli kusengaphambili inkulu kakhulu.Uma i-engeli engaphambili yokunikezwa kukaphethiloli yenjini ye-diesel inkulu kakhulu, ukucindezela kokucindezela kanye nezinga lokushisa kusilinda kuncane kakhulu, okuzophazamisa ukusebenza kokusha kukaphethiloli.Injini kadizili iqala ukusha, ukushiswa kukaphethiloli akuphelele, futhi injini kadizili ikhipha intuthu emnyama embi kakhulu.Ngaphezu kwephutha lentuthu emnyama yenjini kadizili elibangelwa i-engeli enkulu yokunikezwa kukaphethiloli kusengaphambili, kukhona nezimo ezilandelayo:.Kunomsindo ovuthayo, amandla enjini kadizili awanele, nokusetshenziswa kukaphethiloli kukhuphuka kakhulu.isixhumi esibonakalayo sepayipi le-exhaust limanzi noma amafutha aconsayo Izinga lokushisa le-exhaust lingase libe phezulu, futhi ipayipi yokukhipha ingashisa ibe bomvu.B. i-engeli yokunikezwa kukawoyela ngaphambi kwesikhathi incane kakhulu Uma i-engeli engaphambili yokunikezwa kukaphethiloli yenjini kadizili incane kakhulu futhi kugejwa isikhathi esingcono kakhulu lapho uphethiloli ujovwa kusilinda, ukusha kwenjini kuzokwanda, futhi Inani elikhulu likaphethiloli lizokhishwa kusilinda ngaphambi kokuba lishiswe ngokuphelele, futhi injini yedizili izokhipha intuthu emnyama.Ngaphezu kwephutha lentuthu emnyama yenjini kadizili elibangelwa i-engeli encane yokunikezwa kukaphethiloli kusengaphambili, kukhona nezimo ezilandelayo:.Izinga lokushisa le-exhaust liphezulu futhi ipayipi lokukhipha libomvu
.izinga lokushisa eliphelele lenjini kadizili liphezulu, injini yedizili ishisa ngokweqile ngenxa yokwanda kokusha, amandla enjini kadizili awanele, nokusetshenziswa kukaphethiloli kukhuphuka kakhulu.
Ukuxazulula inkinga: uma kuqinisekiswa ukuthi intuthu emnyama yenjini kadizili idalwa i-engeli engalungile yokuphakela uphethiloli kusengaphambili, iphutha lingaqedwa inqobo nje uma i-engeli yokunikezwa kukaphethiloli ilungiselwe i-engeli yokuklama.

(2) I-plunger noma ivalvu yokudiliva yepompo yomjovo kaphethiloli igugile kakhulu
Ukuguga okujulile komuntu ngamunye noma wonke ama-plunger epompo yomjovo kaphethiloli noma ama-valve aphumayo kuzoholela ekwehleni komfutho kawoyela wephampu wephampu yomjovo kaphethiloli, ukuze ingcindezi eyakhelwe phezulu yomjovo kaphethiloli (nozzle) isale ngemuva, ukushiswa kukaphethiloli akwanele, futhi i-aftercobustion iyanda, ngakho injini kadizili ikhipha intuthu emnyama engathi sína.I-plunger nevalve yokuphuma yamasilinda ngamanye anezinkinga, ezingeke zibe nomthelela omkhulu ekusetshenzisweni kwenjini kadizili ngaphandle kwentuthu emnyama yenjini kadizili.Kodwa-ke, uma i-plunger nevalve yokuphuma yepompo yomjovo kaphethiloli igugile kakhulu, kunezigigaba ezilandelayo ngenkathi ibangela intuthu emnyama embi kakhulu yenjini kadizili:.Kunzima ukuqala injini kadizili
.inani lamafutha okugcoba enjini ye-diesel lingakhuphuka.Amandla enjini kadizili awanele
.izinga lokushisa le-exhaust lenjini ye-diesel liphezulu, futhi ipayipi yokukhipha ingashisa ibomvu.Injini kadizili ingase ishise kakhulu ngenxa yokwanda kokusha ngemva komlilo Indlela eyisisekelo yokuqinisekisa ukuthi intuthu emnyama yenjini kadizili ibangelwa ukuguga kwe-plunger noma i-valve yokukhipha uwoyela imi kanje:
A. khipha ipayipi lokukhipha umoya lenjini kadizili, qala injini yedizili ngesivinini esiphansi, qaphela ngokucophelela isimo sokuphuma kwentuthu kwechweba ngalinye lenjini kadizili, thola isilinda esikhipha intuthu enkulu, bese ubuyisela isijojo sikaphethiloli i-cylinder (engakwazi ukushintshaniswa nesilinda ngaphandle kwentuthu emnyama).Uma isilinda sisakhipha intuthu emnyama kanti enye isilinda ingakhiphi intuthu emnyama, Kungaqinisekiswa ukuthi kunenkinga nge-plunger noma i-outlet valve yepompo yokujova uphethiloli yalesi silinda.  
B. ngaphandle kokukhipha ipayipi lokukhipha umoya, sebenzisa isilinda esisodwa indlela yokucima umlilo ukuze uqinisekise kuqala ukuthi ingabe ikhona inkinga nge-plunger / ivalve yokukhipha uwoyela noma isijojo sikaphethiloli (umbhobho).Indlela eqondile iwukuqala injini kadizili ngesivinini esiphansi, unqamule isilinda sikawoyela ngesilinda, futhi ubheke ukushintsha kwentuthu lapho uphuma ipayipi le-exhaust.Isibonelo, uma intuthu yenjini ye-diesel iyancipha ngemva kokuba uwoyela unqanyuliwe ku-cylinder, Lokhu kubonisa ukuthi kunenkinga ngohlelo lokuhlinzeka ngophethiloli (i-plunger / outlet valve noma i-injector) yesilinda.Ukuxazulula izinkinga: uma lezi zinkinga zenzeka ngesikhathi sokusebenza kwenjini ye-diesel, ipompo yomjovo kaphethiloli kufanele ihlolwe.Uma kuqinisekiswa ukuthi iphutha libangelwa ukuguga okukhulu kwe-plunger ne-valve yokuphuma, iphutha lingaqedwa ngemva kokulungiswa kabusha kwephampu yomjovo kaphethiloli.  
Inothi elikhethekile: lapho ulungisa kabusha iphampu yomjovo kaphethiloli, buyisela i-plunger, ivalvu yokukhipha uwoyela kanye namagasket afanele ngesethi ephelele (konke), hlola i-engeli yokunikezwa kukawoyela yesilinda ngasinye bese ulungisa ukunikezwa kukawoyela njengoba kudingeka.

(3) Inkinga yomjovo wesibaseli (nozzle).
A. ukungasebenzi kahle kwe-atom, ukuminyana noma ukuconsa kawoyela okungathi sína komlomo womjovo kaphethiloli
Lapho umjovo kaphethiloli (ubhobhosi) wosilinda owodwa wonakalisiwe, okungukuthi, lapho umjovo kaphethiloli (ubhobhosi) wesilinda wenziwe kabi i-athomu, ubambeke noma uconsa kakhulu, kuzodala ukushiswa kukaphethiloli okungaphelele kwesilinda futhi kubangele intuthu emnyama embi kakhulu. yesilinda.Uma kunenkinga ngomjovo kaphethiloli (umbhobho), ngaphezu kokubangela intuthu emnyama enjinini kadizili, kunezimo ezilandelayo:
.isixhumi esibonakalayo sepayipi le-exhaust simanzi, futhi uwoyela wedizili ungase wehle ezimweni ezimbi kakhulu.Ipiston yesilinda eliwisayo lingashisa phezulu noma lidonse isilinda.Isilinda singaba nomsindo wokusha onamandla {B kanye nomfutho womjovo ongalungile
Ingcindezi yomjovo engalungile (enkulu kakhulu noma encane kakhulu) izophazamisa isikhathi sokwakha ingcindezi yomjovo, ibambezeleke noma iqhubekisele phambili i-engeli yokunikezwa kukaphethiloli, futhi yenze injini kadizili ikhiphe intuthu emnyama ngesikhathi sokusebenza.Umfutho omningi womjovo ungase ubambezele isikhathi sokuqala komjovo futhi kwandise ukusha kwenjini kadizili.Ingcindezi yomjovo
Kungani i-fuel burner ihlale icishiwe

Buka umbhalo ogcwele
Amandla mancane kakhulu, angase aqhubekisele phambili isikhathi sokuqala komjovo kaphethiloli futhi kwandise ukusha kwenjini kadizili ngaphambi kwesikhathi.Izinkinga nezimo ezibangelwa yilokhu okubili kufana ne-engeli engalungile yokunikezwa kukawoyela okukhulunywe ngenhla.  
Indlela yokuqinisekisa ukuthi ingabe ikhona yini inkinga ngomjovo (nozzle) wesilinda ngokuyisisekelo iyafana nendlela yokuqinisekisa ukuthi ikhona yini inkinga nge-valve yokukhipha ipayipi / yokuphuma, ngaphandle kokuthi ngemva kokushintshaniswa komjovo, inombolo yesilinda. isikhathi eside sikhipha intuthu emnyama futhi enye isilinda ikhipha intuthu emnyama, okukhombisa ukuthi kunenkinga ngomjovo (nozzle).Ukuxazulula inkinga: buyisela umjovo kaphethiloli noma ukuhlanganiswa komjovo kaphethiloli we-cylinder.Lapho ushintsha umjovo kaphethiloli, qiniseka ukuthi uwumkhiqizo ofanelekayo wohlobo olufanayo, hlola futhi ulungise umfutho womjovo kaphethiloli njengoba kudingekile, qaphela ngokucophelela ikhwalithi ye-atomization yesijovo sikaphethiloli noma ukuthi zikhona yini izinkinga njengokuconsa uwoyela wejubane eliphansi. , ukuze kuqinisekiswe ukuthi i-fuel injector (nozzle) enekhwalithi ephezulu isetshenziswa.
