Mota yedhiziri imhando yemotokari inofambiswa neinjini yedhiziri, iyo inogadzira simba kuburikidza nekudzvanywa kwemhepo uye jekiseni remafuta. Diesel injini dzinozivikanwa nepamusoro-soro torque uye yakaderera rpm, izvo zvinoita kuti dzive dzakanyatsokodzera kushandiswa mumotokari dzinorema-basa uye marori.
Nhau yemotokari dzedhiziri inotangira muzana remakore rechi19, apo injini yedhiziri yokutanga yakaumbwa naFerdinand Porsche muna 1892. Zvisinei, pakanga pasati pave kutozosvikira muzana ramakore rechi20 apo injini dzedhiziri dzakavamba kuwana mukurumbira muindasitiri yemotokari.
Mumakore ekuma1930, German automaker BMW yakagadzira imwe yemotokari dzedhiziri dzekutanga dzakabudirira, BMW 220. Mota iyi yaive ne 2.2-litre four-cylinder four-cylinder diesel engine iyo yaiburitsa yakanyanya kubuda 75 马力。BMW 220 yakabudirira, uye zvakabatsira kumisikidza mota dzedhiziri senzira inoshanda kune vanogadzira mota.
Kubva ipapo, mota dzedhiziri dzave kuwedzera mukurumbira muindasitiri yemotokari. Magadzirirwo emotokari dzedhiziri akashandukawo nekufamba kwenguva. Mota dzedhiziri dzekutanga dzakagadzirwa neinjini yecylinder imwe chete, asi sezvo tekinoroji yakavandudzwa, magadzirirwo emotokari dzedhiziri akawedzerawo. Nhasi, mota dzedhiziri dzinowanzo kuve dzakashongedzerwa neakawanda-cylinder injini dzinopa kuvandudzwa kwekuita uye kugona.
Imwe yemabhenefiti akakosha emotokari dzedhiziri ndeyekugona kwemafuta. Injini dzedhiziri dzinozivikanwa nekudzika rpm uye torque yakakwira, izvo zvinoita kuti dzive dzakanyatsokodzera kushandiswa mumotokari dzinorema uye marori. Izvi zvinobvumira mota dzedhiziri kuti dziwane yakakwira mafuta ekufambisa ichiri kupa simba uye rakavimbika ruzivo rwekutyaira.
Pamusoro pekushanda kwavo, mota dzedhiziri dzinopawo mamwe mabhenefiti akati wandei. Vanowanzova nesimba kupfuura vamwe vavo vane peturu, uye havanawo ruzha uye vane hushamwari. Mota dzedhiziri zvakare dzine hupenyu hurefu hwesevhisi kupfuura mota dzepeturu, sezvo dzakagadzirirwa kutsungirira tembiricha yepamusoro uye kumanikidzwa kunowanikwa mukupisa.
Pakazere, mota dzedhiziri isarudzo ine simba uye inoshanda kune vatyairi vanoda yakavimbika uye ine simba yekutyaira ruzivo. Ne torque yavo yakakwirira uye yakaderera rpm, motokari dzedhiziri dzakanyatsokodzera kushandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira motokari dzinorema uye marori. Kubudirira kwavo uye kuderedzwa kwehutsi kunoita kuti vave sarudzo ine hushamwari kwezvakatipoteredza zvakare.
