I-injini ye-diesel emnyama yomsi inezizathu ezimbalwa.ngokweengxaki eziqhelekileyo ezifunyenweyolandela izizathu:

1.ingxaki yenkqubo yokutofa ngamafutha

2.Ingxaki yokutshisa inkqubo

3.Ingxaki yenkqubo yokuthatha

Ingxaki ye-4.Exhaust system

5.Others umzekelo ingxaki umgangatho diesel, iindawo ezihambelana nengxaki

Indlela yokuqinisekisa ngokuchanekileyo isizathu kunye nokulungisa?

1) Unikezelo lwamafutha engile engalunganga.I-engile yonikezelo lwamafutha kwangaphambili ye-injini ye-diesel yeyona engile yangaphambili yokuqinisekisa ukutsha okupheleleyo kwamafutha emva kokungena kwi-cylinder.I-angle engaphambili nayo yahlukile kwiimodeli ezahlukeneyo.I-engile engalunganga yesitofu iya kukhokelela ekutshisweni kwamafutha angonelanga kunye nokungaphelelanga kwe-injini ye-diesel, okuya kukhokelela kumsi omnyama we-injini ye-diesel.a.I-engile yonikezelo lwamafutha kwangaphambili inkulu kakhulu.Ukuba i-engile yonikezelo lwamafutha kwangaphambili ye-injini ye-diesel inkulu kakhulu, uxinzelelo loxinzelelo kunye nobushushu kwi-cylinder iphantsi kakhulu, eya kuchaphazela ngokuthe ngqo ukusebenza kokutsha kwamafutha.Ukutsha kwangaphambili kwe-injini ye-diesel kuyenyuka, ukutsha kwepetroli akugqibelelanga, kwaye injini ye-diesel ikhupha umsi omnyama omkhulu.Ukongeza kwimpazamo yomsi omnyama we-injini ye-diesel ebangelwa yi-angle enkulu yonikezelo lwamafutha kwangaphambili, kukwakho ezi ziganeko zilandelayo:.Kukho ingxolo emandla yokutsha, amandla e-injini ye-diesel ayonelanga, kunye nokusetyenziswa kwamafutha kunyuka kakhulu.Ujongano lombhobho wokukhupha umanzi okanye ioli ethontsizayo Ubushushu bombhobho bunokuba phezulu, kwaye umbhobho wokukhupha ungatshisa ubomvu.B. i-engile yonikezelo lwe-oyile yangaphambili incinci kakhulu Ukuba i-engile yonikezelo lwe-oyile kwangaphambili ye-injini ye-diesel incinci kakhulu kwaye ixesha elingcono lilahlekile xa i-fuel igalelwe kwisilinda, ukutshiswa kwesithuba se-injini ye-diesel kuya kwanda, kwaye a umthamo omkhulu wamafutha uya kukhutshelwa kwisilinda phambi kokuba utshiswe ngokupheleleyo, kwaye injini yedizili iya kukhupha umsi omnyama kakhulu.Ukongeza kwimpazamo yomsi omnyama we-injini ye-diesel ebangelwa yi-angle encinci yonikezelo lwamafutha kwangaphambili, kukwakho ezi ziganeko zilandelayo:.Iqondo lokushisa liphezulu kwaye umbhobho wokukhupha ubomvu
.Iqondo lobushushu lilonke le-injini ye-diesel liphezulu, i-injini ye-diesel ishushu kakhulu ngenxa yokwanda kokutshiswa emva kokutsha, amandla e-injini ye-diesel ayonelanga, kunye nokusetyenziswa kwamafutha kunyuka kakhulu.
Ukusombulula ingxaki: ukuba kuqinisekisiwe ukuba umsi omnyama we-injini ye-diesel ubangelwa yi-engile engachanekanga yonikezelo lwamafutha kwangaphambili, impazamo inokupheliswa ukuba nje i-engile yonikezelo lwamafutha kwangaphambili ilungelelaniswe kwi-engile yoyilo.

(2) I-plunger okanye ivalve yokuhambisa yempompo yokutofa ngamafutha igugile kakhulu
Ukunxitywa okunzulu komntu ngamnye okanye zonke iipungeli zempompo yokutofa ngamafutha okanye iivalvu zokuphuma ziya kukhokelela ekwehleni koxinzelelo lweoyile yempompo yempompo yokutofa ngamafutha, ukuze uxinzelelo olwakhiweyo lwesitofu samafutha (umbhobho) lube ngasemva, ukutsha kwepetroli akwanelanga, kwaye i-aftercombustion iyanda, ngoko ke injini ye-diesel ikhupha umsi omnyama omnyama.Ivalve ye-plunger kunye ne-outlet ye-cylinders nganye ineengxaki, ezingayi kuba nempembelelo enkulu ekusebenziseni injini ye-diesel ngaphandle komsi omnyama we-injini ye-diesel.Nangona kunjalo, ukuba i-plunger kunye nevalve yokuphuma yempompo yokutofa ngamafutha zigugile kakhulu, kukho ezi ziganeko zilandelayo ngelixa zibangela umsi omnyama omnyama we-injini ye-diesel:.Kunzima ukuqalisa injini yedizili
.isixa se-oyile yokuthambisa ye-injini ye-diesel inokunyuka.Amandla enjini yedizili ayonelanga
.iqondo lobushushu lokukhupha le-injini ye-diesel liphezulu, kwaye umbhobho wokukhupha ungatshisa ubomvu.I-injini ye-diesel inokutshisa ngokugqithisileyo ngenxa yokwanda kokutshiswa emva kokutshiswa Indlela esisiseko yokuqinisekisa ukuba umsi omnyama we-injini ye-diesel ubangelwa kukuguga kwe-plunger okanye ivalve yokukhupha i-oyile ngolu hlobo lulandelayo:
A. susa umbhobho wokukhupha we-injini ye-diesel, qalisa injini ye-diesel ngesantya esiphantsi, qwalasela ngenyameko imeko yokukhupha umsi kwi-port yokukhupha nganye ye-injini ye-diesel, fumana i-cylinder enombhobho wokukhupha umsi omkhulu, kwaye ubeke indawo yesitofu se-fuel. i-cylinder (enokuthi itshintshe kunye ne-cylinder ngaphandle komsi omnyama).Ukuba i-cylinder isakhupha umsi omnyama kwaye enye i-cylinder ayikhuphi umsi omnyama, kunokuqinisekiswa ukuba kukho ingxaki kwi-plunger okanye ivalve yokuphuma yempompo yokutofa kwamafutha yale cylinder.  
B. ngaphandle kokususa umbhobho wokukhupha, sebenzisa indlela yokucima umlilo ye-cylinder enye ukuze uqinisekise kwangaphambili ukuba kukho ingxaki nge-plunger / ivalve yokukhupha i-oyile okanye isitofu se-fuel (umlomo).Indlela ekhethekileyo kukuqalisa injini ye-diesel ngesantya esiphantsi, ukusika i-cylinder yeoli nge-cylinder, kwaye uqaphele utshintsho lomsi ekuphumeni kombhobho wokukhupha.Ngokomzekelo, ukuba umsi we-injini ye-diesel uyancipha emva kokuba ioli inqunyulwe kwi-cylinder, oku kubonisa ukuba kukho ingxaki kwindlela yokubonelela ngamafutha (i-plunger / i-valve yokuphuma okanye i-injector) ye-cylinder.Ukuxazulula iingxaki: xa ezi ngxaki zisenzeka ngexesha lokusebenza kwe-injini ye-diesel, i-fuel injection pump pump kufuneka ihlolwe.Ukuba kuqinisekiswa ukuba impazamo ibangelwa ukuguga okunzulu kwe-plunger kunye ne-valve yokuphuma, impazamo inokupheliswa emva kokugqithisa impompo yokutofa kwe-fuel.  
Inqaku elikhethekileyo: xa ulungisa impompo ye-injection ye-fuel, buyisela i-plunger, i-valve yokukhupha i-oyile kunye ne-gaskets efanelekileyo kwisethi epheleleyo (zonke), khangela i-angle yokubonelela nge-oyile ye-cylinder nganye kwaye ulungelelanise ukunikezelwa kweoli njengoko kufuneka.

(3) Ingxaki yesitofu samafutha (umbhobho).
A. Ukungafezeki kakuhle kwe-atom, ukuxinana okanye ukuthontsiza kwe-oyile evuzayo kumbhobho wenaliti yamafutha
Xa isitofu samafutha (umbhobho) sombhobho othile sonakalisiwe, oko kukuthi, xa isitofu se-fuel (umlomo) sesilinda singasebenzi kakuhle, sibambekile okanye sithontsize kakhulu, siya kubangela ukutsha kwepetroli okungaphelelanga kwesilinda kwaye kubangele umsi omnyama onzulu. ye cylinder.Xa kukho ingxaki ngesitofu se-fuel (umlomo), ngaphezu kokubangela umsi omnyama ophuma kwi-injini ye-diesel, kukho ezi ziganeko zilandelayo:
.I-interface yombhobho wokukhupha imanzi, kwaye ioli ye-diesel inokuhla kwiimeko ezinzima.Ipiston yesilinda inokutshisa ngaphezulu okanye itsale isilinda.I-cylinder inokuba nesandi esinamandla sokutsha {B kunye noxinzelelo lwenaliti engalunganga
Uxinzelelo lwenaliti olungafanelekanga (olukhulu kakhulu okanye luncinci kakhulu) luya kuchaphazela ixesha lokwakha uxinzelelo lwe-injector, ukulibaziseka okanye ukuqhubela phambili i-engile yonikezelo lwamafutha kwangaphambili, kwaye yenze injini yedizili ikhuphe umsi omnyama ngexesha lokusebenza.Uxinzelelo oluphezulu lwenaliti lunokulibazisa ixesha lokuqala lokutofa kunye nokwandisa ukutsha kwe-injini yedizili emva kokutshiswa.Uxinzelelo lwesitofu
Kutheni isitshisi samafutha sisoloko sicinyiwe

Jonga isicatshulwa esipheleleyo
Amandla mancinci kakhulu, anokuthi aqhubele phambili ixesha lokuqala lokutofa kwamafutha kwaye anyuse ukutsha kwangoko kwenjini yedizili.Iingxaki kunye neziganeko ezibangelwa zezi zimbini zifana ne-oyile engachanekanga echazwe ngasentla.  
Indlela yokuqinisekisa ukuba kukho ingxaki nge-injector (nozzle) ye-cylinder ngokusisiseko iyafana nendlela yokuqinisekisa ukuba kukho ingxaki kwi-plunger / ivalve yokuphuma, ngaphandle kokuba emva kokuba i-injector itshintshiwe, i-cylinder no. ixesha elide likhupha umsi omnyama kwaye enye i-cylinder ikhupha umsi omnyama, ebonisa ukuba kukho ingxaki kwi-injector (nozzle).Ukusombulula ingxaki: buyisela i-injector ye-fuel okanye i-fuel injector assembly ye-cylinder.Xa utshintsha isitofu se-fuel, qinisekisa ukuba iyimveliso yohlobo olufanayo, jonga ngokungqongqo kwaye uhlengahlengise uxinzelelo lwenaliti yamafutha njengoko kufuneka, jonga ngononophelo umgangatho we-atomization yesitofu samafutha okanye ukuba kukho iingxaki ezinjengokuthontsiza kweoyile enesantya esiphantsi. , ukuze kuqinisekiswe ukuba isitofu samafutha (umlomo) esinomgangatho ophezulu siyasetyenziswa.
