Kune mhando mbiri dzakasiyana dzeV8 injini zvinoenderana ne crankshaft.

Ndege yakatwasuka yakajairika V8 chimiro mumotokari dzemuAmerica. Kona iri pakati pegirengi rega rega muboka (boka re4) uye rakapfuura iri 90 °, saka inomira yakamira kana ichionekwa kubva kune imwe mugumo we crankshaft. Iyi nzvimbo yakatwasuka inogona kuwana chiyero chakanaka, asi inoda huremu hunorema simbi. Nekuda kweiyo hombe inotenderera inertia, iyo V8 injini ine iyi yakamira chimiro ine yakaderera kukurumidza, uye haigone kukurumidza kana kudzika nekukurumidza kana ichienzaniswa nemamwe marudzi einjini. Kutevedzana kwekudzima kweinjini yeV8 ine chimiro ichi kubva pakutanga kusvika kumagumo, izvo zvinoda dhizaini yekuwedzera exhaust system yekubatanidza mapombi ekuburitsa kumagumo ese. Iyi yakaoma uye inoda kuomesera exhaust system ikozvino yave musoro mukuru kune vanogadzira mota dzemujaho wemujaho mumwe chete.

Ndege zvinoreva kuti crank iri 180°. Chiyero chavo hachina kunyatsokwana, kunze kwekunge shaft yechiyero ichishandiswa, kudengenyeka kwakakura kwazvo. Nekuti hapana kudikanwa kwesimbi inopikisa, crankshaft ine huremu hwakaderera uye yakaderera inertia, uye inogona kuve nekumhanya kukuru uye kukurumidza. Chimiro ichi chakajairika mumotokari yemazuva ano ye1.5-litre Coventry Climax. Injini iyi yakashanduka kubva kundege yakatwasuka kuenda pachimiro chakati sandara. Mota dzine V8 chimiro Ferrari (Dino injini), Lotus (Esprit V8 injini), uye TVR (Speed ​​Eight injini). Chimiro ichi chakanyanya kuwanda mumijaho injini, uye inozivikanwa kwazvo Cosworth DFV. Kugadzirwa kwechimiro chechimiro chakaoma. Nechikonzero ichi, mazhinji ekutanga V8 injini, kusanganisira De Dion-Bouton, Peerless uye Cadillac, akagadzirwa ane sandara chimiro. Muna 1915, iyo vertical design concept yakaonekwa pamusangano weAmerican automotive engineering, asi zvakatora makore masere kuti gungano riitwe.
