Injini, mota muchina unogona kushandura mamwe mafomu esimba kuita magetsi emagetsi, anosanganisira injini dzinopisa dzemukati (peturu, nezvimwewo), injini dzinopisa dzekunze (Stirling engines, steam engines, etc.), mota dzemagetsi, etc. , injini dzinopisa mukati dzinowanzoshandura simba remakemikari kuita simba remagetsi.Injini inoshanda kune ese ari maviri emagetsi ekugadzira mudziyo uye muchina wese kusanganisira mudziyo wemagetsi.Injini yakatanga kuberekwa muEngland, saka pfungwa yeinjini inobvawo kuChirungu.Chirevo chayo chepakutanga chinoreva "muchina wemuchina unogadzira simba."

Muviri ndiwo skeleton yeinjini uye hwaro hwekuisa kune akasiyana masisitimu uye masisitimu ejini.Zvese zvikamu zvikuru uye zvishongedzo zveinjini zvakaiswa mukati nekunze kwayo, uye inotakura mitoro yakasiyana siyana.Nokudaro, muviri unofanirwa kuva nesimba rakakwana uye kusimba.Iyo injini block inonyanya kuumbwa cylinder block, cylinder liner, cylinder head, cylinder gasket uye zvimwe zvikamu.

Nheyo yekushanda yeinjini yakakamurwa kuita 4 sitiroko zvikamu: kutora sitiroko, compression sitiroko, simba sitiroko, uye kupera simba.FAW-Volkswagen Star kugadzirisa nyanzvi yakataura kuti munguva yechando, mafuta einjini, mafuta ebhureki uye antifreeze mukamuri yeinjini zvinofanirwa kuongororwa nguva nenguva kuona kana oiri yacho yakakwana, kana yadzikira, uye kana yave nguva yekutsiviwa.Mafuta aya akafanana neropa remota yako.Iyo yekutsiva kutenderera inofanirwa kutsiviwa kuti ive nechokwadi chekutenderera kwemafuta.

Injini dzakajairika muhupenyu hwedu hwezuva nezuva injini dzemotokari;dzakakamurwa kuva injini dzepeturu uye injini dzedhiziri maererano nemafuta akasiyana.Iri rudzi rweinjini rinowanzo kuumbwa ne "makitani maviri makuru uye masisitimu makuru mashanu", anoti, crank yekubatanidza tsvimbo, chitima chevharuvhu, system yekugovera mafuta, yekutanga system, yekutonhodza system, lubrication system, uye ignition system.Injini yedhiziri haina hurongwa hwekudzima moto.Inozvipisa pachayo pasi pekushisa kwepamusoro uye kumanikidzwa nekupinza mafuta muimba yekupisa nenzira yehuputi hwepamusoro.
