Injini yemotokari ndiyo mudziyo unopa simba kumotokari, uye ndiwo moyo wemotokari, unosarudza simba, hupfumi, kugadzikana uye kuchengetedzwa kwezvakatipoteredza kwemotokari. Zvichienderana nemagetsi akasiyana, mainjini emotokari anogona kukamurwa kuita mainjini edhiziri, mainjini epeturu, mainjini emagetsi uye simba rehybrid.
Injini dzepeturu nedzedhiziri dzinoshandiswawo muinjini dzinopisa mafuta dzinochinja simba remakemikari remafuta kuita simba remuchina rekufamba kwepiston nesimba rekubuda kwemafuta. Injini yepeturu ine zvakanakira zvekumhanya kwakanyanya, mhando yakaderera, ruzha rushoma, kutanga kuri nyore uye mutengo wakaderera wekugadzira; Injini yedhiziri ine chiyero chepamusoro chekumanikidzwa, kushanda zvakanaka kwekupisa, kushanda zvakanaka kwehupfumi uye kushanda zvakanaka kwemhepo kupfuura injini yepeturu.
Injini iyi ine nzira mbiri huru, dzinoti nzira yekubatanidza tsvimbo yemagetsi (crank connecting rod mechanism) uye nzira yekuvhara vharuvhu, pamwe chete nedzimwe nzira huru shanu, dzakadai sekutonhodza, kunyorovesa, kupinza, kupa mafuta uye kutanga. Zvinhu zvikuru i cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel nezvimwewo. Kamuri rekushanda reinjini ye reciprocating piston internal combustion inonzi cylinder, uye pamusoro pe cylinder iri cylindrical. Piston inodzosera mu cylinder yakasungirirwa nemucheto mumwe wetsvimbo inobatanidza kuburikidza nepiston pin, uye mumwe mugumo wetsvimbo inobatanidza wakabatana ne crankshaft, iyo inotsigirwa ne bearing iri pa cylinder block uye inogona kutenderedzwa mu bearing kuti igadzire nzira yekubatanidza tsvimbo yemagetsi (crank connecting rod mechanism). Kana piston ichifamba ichidzokera shure nemberi mu cylinder, tsvimbo inobatanidza inosunda crankshaft kuti itenderere. Kusiyana neizvi, kana crankshaft ichitenderera, journal yetsvimbo inobatanidza inofamba yakatenderera mu crankcase uye inotyaira piston kumusoro nekudzika mu cylinder kuburikidza netsvimbo inobatanidza. Kutenderera kwega kwega kwecrankshaft, piston inomhanya kamwe chete nguva imwe neimwe, uye vhoriyamu yecylinder inogara ichichinja kubva padiki kuenda pakuru, uye kubva pakuru kuenda padiki, zvichingodaro. Pamusoro pecylinder pakavharwa nemusoro wecylinder. Mavharuvhu ekupinda nekubuda anopihwa pamusoro wecylinder. Kuburikidza nekuvhurwa nekuvharwa kwemavharuvhu ekupinda nekubuda, zvinoonekwa kuti zvinochaja mukati mecylinder nekubuda kunze kwecylinder. Kuvhurwa nekuvharwa kwemavharuvhu ekupinda nekubuda anofambiswa necamshaft. Camshaft inofambiswa necrankshaft kuburikidza nebhandi rine mazino kana giya.
