Ithayile evuthayo ye-injini ikwabizwa ngokuba yi-tile yokukrwela, ukubamba ithayile. Ukuba iithayile zokuthwala i-crankshaft kunye nokuthwala intonga zokudibanisa azithanjiswanga kakuhle, oko kuya kubangela ukuguga kunye nokunye okwenzekayo, okuyimpazamo enkulu neyingozi kakhulu. Imikrwelo, iimeko ezinzima ziya "kubamba i-shaft" kwaye ziphule i-crankshaft.
Oku kulandelayo luhlalutyo olufutshane lwezizathu ezininzi eziqhelekileyo zokuba injini ibambe ithayile.
Kwiimeko ezininzi, injini itshixiwe ngenxa yokungathanjiswa kakuhle kwe-oyile ye-injini. Iimeko zokusebenza ze-injini zimbi kakhulu, kwaye umthwalo wobushushu be-injini kunye nobushushu obuphezulu buqhele ukwenzeka. Ukuba ibakala elifanelekileyo leoli alinakukhethwa ngokwemigaqo yokusetyenziswa okanye i-oyile engeyonyani nengaphantsi ayinakusetyenziselwa ukubonelela ngokuthambisa okulungileyo kwisihlahla esithwalayo, ukunxiba okungaqhelekanga kwesihlahla esithwalayo kuya kwenzeka, kwaye ukusebenza kwexesha elide kuya kukhokelela ekugqibeleni. ukusilela kwesihlahla esithwalayo.
Ezinye ii-injini zinokusilela ngenxa yobude obungonelanga bokulayisha kwangaphambili xa ukuthwala kudityaniswa. Ukuba ukuphakama komthwalo wetyholo elithweleyo akwanelanga, ukulingana phakathi kwetyholo elithweleyo kunye nomngxuma wesihlalo kumzimba wesihlalo kuya kunganelanga, nto leyo engabandakanyi ukutshatyalaliswa kobushushu behlathi elithweleyo, eliya kubangela ukuba ukubanjwa, kwaye ityholo elithwalayo liya kujikeleza kumngxunya wesihlalo, okukhokelela ekugugeni okungaqhelekanga kwesitulo esinesihlahla. Ukujikeleza kubangela ukuba umgodi weoli uvalwe, kwaye ukushisa kwehlathi elithwalayo kuphakama kuze kube yilapho kutshisa kwaye ukungaphumeleli kokubamba ihlathi kwenzeka.
Ukuba ukuphakama kokulayisha kwangaphambili kwesihlahla esithwalayo kukhulu kakhulu, kuya kubangela ukuba isihlahla esithwalayo. Ukuba ukuphakama komthwalo wetyholo elithweleyo likhulu kakhulu, isihlahla esithwalayo siya konakala emva kokuhlanganisana, umphezulu wetyholo elithweleyo uya kushwabana, kwaye umsantsa ohambelanayo phakathi kwesihlahla esithwalayo kunye ne-crankshaft uya konakaliswa, oya kuthi ekugqibeleni ukhokele. ukusilela kwetyholo elithwalayo.
