Izinjini zikaphethiloli zisebenzisa uphethiloli njengophethiloli ukuguqula amandla angaphakathi abe amandla e-kinetic. Ngenxa yokuthi uphethiloli une-viscous futhi uhwamuka ngokushesha, uphethiloli ungajovwa kusilinda ngohlelo lomjovo lukaphethiloli. Ngemva kokuba ukucindezela kufinyelele ezingeni elithile lokushisa nokucindezela, kuthungelwa ngepulaki yenhlansi ukuze igesi yande futhi yenze umsebenzi.

Inzuzo:
1. Intengo yenguqulo kaphethiloli ishibhile, futhi ukugcinwa kulula kakhulu futhi akunazinkathazo. Kulula kakhulu ukushintsha izingxenye ku-RV kaphethiloli kunodizili.
2. Ijubane lenjini kaphethiloli liphezulu (okwamanje, ijubane lenjini kaphethiloli lamaloli ngokuvamile liyi-3000-4000R/MIN, futhi isivinini esikhulu senjini kaphethiloli ezimotweni zabagibeli singafinyelela ku-5000-6000R/MIN), ukuguquguquka okuhle, ukusebenza okuzinzile nokuthambile, ukusebenza okulula nokonga abasebenzi, ukukhanya kwekhwalithi ephezulu, umsindo ophansi, izindleko eziphansi, kulula ukukuqala, njll., ngakho-ke isetshenziswa kakhulu ezimotweni, emalolini amancane naphakathi nendawo nasezimotweni zamasosha angekho emgwaqeni.

Okushodayo:
Izinga lokusetshenziswa kukaphethiloli liphezulu, umnotho uphansi, futhi inkomba yokuhlanza igesi ephumayo iphansi. Ngenxa yokuthi izimoto zenjini kaphethiloli njengezimoto nezimoto zabagibeli zivame ukushayelwa edolobheni, zivame ukuba sesimweni sokuma ngenxa yokuminyana komgwaqo, futhi injini ivamise ukuhamba ngesivinini esiphansi, futhi izinga lokushisa liphansi. Ngisho nangaphansi kwezimo ezivamile zokusebenza, izinga lokushisa nomfutho wezinjini zikaphethiloli liphansi kunaleso sezinjini zikadizili. Ngakho-ke, ngaphansi kwezimo zokusebenza zenjini kaphethiloli, uwoyela wenjini uthambekele ekukhiqizeni udaka olunezinga lokushisa eliphansi, ngakho-ke uwoyela wenjini kaphethiloli uyadingeka ukuze ube nokuhlakazeka okuhle kwe-sludge kwezinga lokushisa eliphansi.

Injini kadizili iyinjini eshisa udizili ukuze ikhiphe amandla. Yasungulwa umsunguli ongumJalimane uRudolf Diesel ngo-1892. Ukuze kuhlonishwe umsunguli, udizili umelelwa yisibongo sakhe sikaDizili, kanti izinjini zikadizili zibizwa nangokuthi izinjini zikaDizili.

Inzuzo:
1. Impilo ende, eyongayo futhi ihlala isikhathi eside. Ijubane lenjini ye-diesel liphansi, izingxenye ezihlobene akulula ukuguga, ukuguga kwezingxenye kungaphansi kwenjini kaphethiloli, futhi impilo yesevisi yinde kakhulu. Alukho uhlelo lokuthungela, futhi zimbalwa izinto zikagesi ezisizayo, ngakho izinga lokuhluleka kwenjini kadizili liphansi kakhulu kunelenjini kaphethiloli.
2. Ukuvikeleka okuphezulu. Uma uqhathaniswa nophethiloli, awuguquguquki kangako, unendawo yokuthungela ephakeme, futhi akulula ukuvutha noma ukuqhuma ngengozi, ngakho ukusebenzisa udizili kuzinzile futhi kuphephe kakhulu kunokusebenzisa uphethiloli.
3. I-torque ephezulu ngesivinini esiphansi. Izinjini zikadizili ngokuvamile zithola i-torque ephezulu ngesivinini esincane, esingcono kunezinjini zikaphethiloli emigwaqweni eyinkimbinkimbi, ekhuphukayo, nemithwalo esindayo. Nokho ayifani nemoto kaphethiloli ngokwejubane nokushayela ngesivinini esiphezulu emgwaqeni omkhulu.

Okushodayo:
1. Indlela yokuthungela yezinjini zikadizili iwukubasa ngokucindezela. Uma iqhathaniswa nezimoto zikaphethiloli, ayinaso isakhiwo se-spark plug. Ngezinye izikhathi amagesi anobuthi akhiqizwa ngenxa yokuntuleka kwe-oxygen eyanele, njengamagesi anobuthi njenge-NOX. umoya, okuphumela ekungcoleni. Ngenxa yalokhu, izimoto zikadizili zifakwe amathangi e-urea angakwazi ukwenza le gesi enobuthi ingabi namandla ukuze ingangcolisi umkhathi.
2. Umsindo wenjini ye-diesel mkhulu kakhulu, obangelwa isakhiwo sayo, esithinta ukunethezeka kokugibela abagibeli. Kodwa-ke, ngokuthuthuka okuqhubekayo kwezobuchwepheshe, ukulawula umsindo wezinjini zikadizili kumamodeli aphakathi kuya kwephezulu kuyefana nowenjini yezimoto.
3. Uma izinga lokushisa liphansi ebusika, uma kukhethwa udizili ongafanele, ipayipi likawoyela liyoba yiqhwa, okuzokwenza injini ye-diesel isebenze ngendlela engavamile.
