A ƙarshen ƙarar fitowar wutar lantarki, watau, gefen inda gearbox da kayan aikin ke haɗawa. Babban aikin jirgin sama shine adana kuzari da rashin kuzari a wajen bugun ƙarfin injin. Ga injin mai-bugun jini huɗu, makamashi ne kawai don tsotsa, matsewa, da shaye shaye don bugun jini ɗaya ya fito ne daga kuzarin da ke cikin kwandon jirgi. An gyara ma'auni ba daidai ba. Daidaita injin din ya dogara ne da ma'aunin ma'auni akan shaft. Injin silinda guda yana da madaidaicin ma'auni na musamman.
Jirgin sama yana da babban lokacin rashin ƙarfi. Tunda aikin kowane silinda na injin yana daina aiki, saurin injin shima yana canzawa. Lokacin da saurin injin ya karu, kuzarin kuzarin abin hawa ya tashi, adana makamashi; lokacin da saurin injin yake raguwa, kuzarin kuzarin jirgi yakan tashi, yana sakin kuzari. Ana iya amfani da kwandon jirgi don rage saurin hawa da sauka a yayin aikin injiniya.
An shigar a ƙarshen ƙarshen crankshaft na injin kuma yana da rashin aiki. Aikinta shine adana kuzarin injin, shawo kan juriya da wasu abubuwan, kuma sanya crankshaft ya juya dai-dai; haɗa injin da watsa motar ta hanyar kamalanda aka sanya akan keken; kuma farawa Injin yana aiki don sauƙaƙe farawa injin. Kuma shine hadewar yanayin crankshaft da hangen nesa da abin hawa.
A cikin bugun wuta, kuzarin da injin ke aikawa zuwa crankshaft, ban da fitarwa na waje, wani ɓangare na kuzarin yana shaƙuwa da ƙwanƙwasa, don haka saurin crankshaft ba zai ƙara yawa ba. A cikin bugun shanyewa guda uku na shaye shaye, cin abinci da matsewa, ƙwallon kwando yana sakin kuzarin da yake ajje don biyan aikin da waɗannan bugun bugun uku suka cinye, don haka saurin crankshaft baya raguwa sosai.
Kari akan haka, tsuntsayen tashi sama suna da ayyuka kamar haka: kazar-kazar wani bangare ne mai aiki na damke rikici; kayan aikin zobe na zoben tashi don farawa injin an saka su a kan bakin jirgi; Hakanan an zana mafi girman alamar matattu a saman jirgi don daidaita lokacin ƙwanƙwasawa ko lokacin shigar da mai, da kuma daidaita bawul.
