Injini dzepeturu dzinoshandisa peturu sehuni kushandura simba remukati kuita kinetic simba. Nekuti peturu ine viscous uye inoputika nekukurumidza, peturu inogona kubaiwa mucylinder ine jekiseni repeturu. Mushure mekudzvanywa kwasvika kune imwe tembiricha uye kudzvanywa, inobatidzwa ne spark plug kuita kuti gasi riwedzere uye riite basa.

Advantage:
1. Mutengo wepetroli version inenge yakachipa, uye kugadzirisa kwakanyatsonaka uye kusina dambudziko. Zviri nyore kutsiva zvikamu paRV peturu pane dhiziri.
2. Kumhanya kweinjini yepeturu kwakakwira (ikozvino, kumhanya kweinjini yepeturu kumarori kazhinji 3000-4000R/MIN, uye kumhanya kwakanyanya kweinjini yepeturu yemotokari dzinotakura vanhu inogona kusvika 5000-6000R/MIN), kuchinjika kwakanaka, kugadzikana uye kupfava kushanda, kuri nyore uye kushanda-kuchengetedza kushanda, yemhando yepamusoro Chiedza, ruzha rwakaderera, mutengo wakaderera, nyore kutanga, nezvimwe, saka inoshandiswa zvakanyanya mumotokari, marori madiki uye epakati nepakati uye mauto asiri munzira mota.

Zvisina kukwana:
Mwero wemafuta ekushandisa wakakwira, hupfumi hwakashata, uye iyo exhaust gasi yekuchenesa index yakaderera. Nekuti mota dzemota dzepeturu dzakaita semota nemota dzevatakuri dzinowanzotyairwa muguta, dzinogara dziri padanho rekumira nekuda kwekusangana kwemigwagwa, uye injini inowanzo mhanya nekumhanya, uye tembiricha yakadzikira. Kunyangwe pasi pemamiriro ekushanda akajairika, tembiricha nekumanikidzwa kweinjini dzepeturu zvakaderera pane zveinjini dzedhiziri. Naizvozvo, pasi pemamiriro ekushanda einjini yepeturu, oiri yeinjini inokwanisa kugadzira yakaderera-tembiricha sludge, saka peturu injini oiri inodiwa kuti ive yakanaka yakaderera-tembiricha sludge dispersion.

Injini yedhiziri injini inopisa dhiziri yekuburitsa simba. Yakagadzirwa nemuumbi wekuGermany Rudolf Diesel muna 1892. Mukukudza muvambi, dhiziri inomiririrwa nezita rake rekuti Diesel, uye injini dzedhiziri dzinonziwo Diesel engines.

Advantage:
1. Hupenyu hurefu, hwehupfumi uye hunogara kwenguva refu. Kumhanya kweinjini yedhiziri kwakadzikira, zvikamu zvine hukama hazvisi nyore kuchembera, kupfeka kwezvikamu kwakaderera pane kweinjini yepeturu, uye hupenyu hwesevhisi hwakareba. Iko hakuna hurongwa hwekudzima, uye kune mashoma ebetsero magetsi emagetsi, saka mwero wekutadza kweinjini yedhiziri wakadzikira zvakanyanya pane weinjini yepeturu.
2. Kuchengetedzwa kwepamusoro. Kana ichienzaniswa nepeturu, hainyanyi kunyungudika, ine poindi yekubatidza yakakwira, uye haisi nyore kubatidzwa kana kuputika netsaona, saka kushandisa dhiziri kwakagadzikana uye kwakachengeteka pane kushandisa peturu.
3. High torque pa low speed. Injini dzedhiziri dzinowanzowana torque yakakwirira nekumhanya kudiki, zviri nani pane injini dzepeturu mumigwagwa yakaoma, kukwira, uye mitoro inorema. Nekudaro, haina kunaka semota yepeturu maererano nekumhanyisa uye kutyaira kwakanyanya mumugwagwa mukuru.

Zvisina kukwana:
1. Iyo nzira yekubatidza yeinjini dzedhiziri ndeye compression ignition. Kana ichienzaniswa nemota dzepeturu, haina spark plug chimiro. Dzimwe nguva magasi ane muchetura anogadzirwa nekuda kwekushaikwa kweokisijeni, senge magasi ane muchetura akadai seNOX. mhepo, zvichikonzera kusvibiswa. Nekuda kweizvi, mota dzedhiziri dzine matangi eurea anogona kumisa gasi rine muchetura iri kudzivirira kusvibisa mhepo.
2. Ruzha rweinjini yedhiziri yakakura, iyo inokonzerwa nechimiro chayo, iyo inokanganisa kutasva kunyaradzwa kwevatakuri. Nekudaro, nekumwe kufambira mberi kwehunyanzvi, kudzora ruzha rweinjini dzedhiziri pakati-kusvika-yepamusoro-yekupedzisira mhando dzakafanana neiyo yeinjini dzemotokari.
3. Kana kutonhora kwakaderera munguva yechando, kana dizeli isina kururama yakasarudzwa, pombi yemafuta inotonhora, izvo zvichaita kuti injini ye dizeli ishande zvisina kunaka.
