Iinjini zepetroli zisebenzisa i-petroli njengesibaso ukuguqula amandla angaphakathi abe ngamandla e-kinetic. Ngenxa yokuba i-petroli i-viscous kwaye iphuma ngokukhawuleza, i-petroli inokutofwa kwi-cylinder ngenkqubo yokutofa kwepetroli. Emva kokuba uxinzelelo lufikelele kubushushu obuthile kunye noxinzelelo, luvutha ngeplagi ye-spark ukwenza igesi yande kwaye yenze umsebenzi.

I-advanteji:
1. Ixabiso lenguqu yepetroli lincinci, kwaye ukugcinwa kulula kakhulu kwaye akunangxaki. Kulula kakhulu ukutshintsha iindawo kwiRV yepetroli kunedizili.
2. Isantya se-injini yepetroli siphezulu (okwangoku, isantya se-injini yepetroli kwiilori ngokuqhelekileyo yi-3000-4000R / MIN, kunye nesantya esiphezulu se-injini yepetroli kwiimoto zomkhweli zinokufikelela kwi-5000-6000R /MIN), Ukuguquguquka okuhle, ukusebenza okuzinzileyo kunye nokuthambileyo, ukusebenza ngokufanelekileyo kunye nokugcina abasebenzi, ukukhanya okuphezulu, ingxolo ephantsi, ixabiso eliphantsi, kulula ukuqala, njl., isetyenziswa kakhulu kwiimoto, iilori ezincinci kunye neziphakathi kunye neenqwelo zomkhosi ezingekho endleleni.

Ukusilela:
Izinga lokusetyenziswa kwepetroli liphezulu, uqoqosho luhlwempuzekileyo, kwaye isalathisi sokucoca igesi ephumayo siphantsi. Ngenxa yokuba iimoto ze-injini yepetroli ezifana neemoto kunye neemoto zabakhweli zihlala ziqhutywa esixekweni, zihlala zikwisimo sokumisa ngenxa yokuxinana kwendlela, kwaye injini ihlala ibaleka ngesantya esingenamsebenzi, kwaye nobushushu buphantsi. Naphantsi kweemeko eziqhelekileyo zokusebenza, ubushushu kunye noxinzelelo lwee-injini zepetroli zingaphantsi kuneenjini zedizili. Ke ngoko, phantsi kweemeko zokusebenza ze-injini yepetroli, i-oyile ye-injini ithanda ukuvelisa i-sludge yobushushu obuphantsi, ngoko ke i-oyile ye-injini yepetroli iyafuneka ukuze kubekho ukusasazwa kodaka olunobushushu obuphantsi.

I-injini ye-diesel yi-injini etshisa idizili ukuze ikhuphe amandla. Yaqanjwa ngumqambi waseJamani uRudolf Diesel ngowe-1892. Ukuhlonipha umenzi wayo, idizili imelwa yifani yakhe ethi Diesel, kwaye iinjini zedizili zikwabizwa ngokuba ziinjini zeDizili.

I-advanteji:
1. Ubomi obude, uqoqosho kunye nokuqina. Isantya se-injini ye-diesel siphantsi, iindawo ezinxulumene nazo akulula ukuguga, ukunxiba kwamacandelo kungaphantsi kwe-injini yepetroli, kwaye ubomi benkonzo bude. Akukho sixokelelwano sokutshisa, kwaye zimbalwa izixhobo zombane ezincedisayo, ngoko ke izinga lokusilela kwe-injini ye-diesel lingaphantsi kakhulu kunelo le-injini yepetroli.
2. Ukhuseleko oluphezulu. Xa kuthelekiswa nepetroli, ayiguquguquki kangako, inendawo yokutshisa ephezulu, kwaye akulula ukuyitshisa okanye ukugqabhuka ngengozi, ngoko ke ukusebenzisa idizili kuzinzile kwaye kukhuselekile kunokusebenzisa ipetroli.
3. Itorque ephezulu ngesantya esiphantsi. Iinjini zedizili zihlala zifumana itorque ephezulu ngesantya esincinci, esingcono kuneenjini zepetroli kwiindlela ezintsonkothileyo, ukunyuka, kunye nemithwalo enzima. Nangona kunjalo, ayilunganga njengemoto yepetroli malunga nokukhawuleza kunye nokuhamba ngesantya esiphezulu kuhola wendlela.

Ukusilela:
1. Indlela yokutshisa iinjini zedizili kukucinywa komlilo. Xa kuthelekiswa neenqwelo zepetroli, ayinayo iplagi yentlantsi. Ngamanye amaxesha iigesi ezinobuthi ziveliswa ngenxa yokungonelanga kweoksijini, njengeegesi ezinobuthi ezifana ne-NOX. umoya, okukhokelela kungcoliseko. Ngenxa yoku, iinqwelo zedizili zixhotyiswe ngamatanki eurea anokuyithothisa le gesi inetyhefu ukuyithintela ekungcoliseni umoya.
2. Ingxolo ye-injini ye-diesel inkulu, ebangelwa isakhiwo sayo, esichaphazela ukukhwela kwabakhweli. Nangona kunjalo, ngenkqubela phambili yetekhnoloji, ulawulo lwengxolo yeenjini zedizili kwiimodeli eziphakathi ukuya kwinqanaba eliphezulu ngokusisiseko luyafana nolo lweenjini zeemoto.
3. Xa iqondo lokushisa liphantsi ebusika, ukuba i-diesel engafanelekanga ikhethiwe, umbhobho weoli uya kubanda, okuya kubangela ukuba injini ye-diesel isebenze ngokungaqhelekanga.
