Umutwe w'Icyuma
Ibaze ko wosubira inyuma mu misi ya mbere y’imiduga. Ford Model T, ikimenyetso c’isi y’imiduga, yari ifise umutwe w’ibara ry’agahama. Ubwo bwoko bw’umutwe w’icuma burangwa n’uko woroshe kandi nk’uko izina ryawo rivyerekana, ukaba uteye neza. Mu moteri y’umutwe ugororotse, uzosanga amavalve ari mu gice ca moteri atandukanye n’umutwe w’icylindre, ivyo bikaba bituma habaho umubumbe ugororotse.

Umutwe w'umuvuduko wo hejuru (OHV)
Uko imodoka zagenda zitera imbere kandi zisaba ubushobozi bwinshi n’ubushobozi bwinshi, umutwe w’ibarabara ry’imbere (OHV) waraserutse nk’ikintu gihindura urukino-. Mu gishushanyo ca OHV, izo valve zishirwa hejuru cane y’igice c’umubiri, mu mutwe w’igice c’umubiri. Ivyo bituma umuntu ashobora kugenzura neza igihe n’ingene amavalve akora, ivyo bikaba bituma moteri ikora neza kandi igakoresha neza amavuta.

Umutwe w'Igikoresho co hejuru (OHC) Umutwe w'Icyuma
Mu kurondera mbere n’ubushobozi n’ubushobozi bwinshi kuruta, abahinga barashizeho umutwe w’icyuma wo hejuru (OHC). Mu buryo butandukanye n’imigero ya OHV, imitwe y’ibipimo vya OHC ishiramwo umugozi w’ibipimo mu mutwe w’ibipimo ubwavyo, igakoresha ata guca ku ruhande amavalve. Iyo ndinganizo ituma umuntu ashobora kugenzura neza neza amavalve be n’igihe akoresha, ivyo bikaba bituma moteri ikora neza kandi igakoresha neza amavuta.

Umutwe w'igice c'umubumbe (Hemi)
Ijambo Hemi ryacitse ijambo rimwe na moteri zikora cane-, bivuye ku moteri za Hemi zakozwe na Chrysler. Imitwe y’ibice vy’umubiri ifise ubuhinga budasanzwe bw’igice c’umubumbe, ifise amavalve ashizwe mu mfuruka, asa n’igice-umubumbe.

Umutwe w'Ikigega c'Ikigega
Naho umutwe w’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara. Mu guhingura amavalve azunguruka, aho gukoresha amavalve asanzwe y’ibipope, amavalve azunguruka akoreshwa mu kugenzura imyuka yinjira n’isohoka. Izo valve zirazunguruka kugira ngo zifungure canke zifunge ivyuho, zigacungera ingene umuyaga ugenda be n’ingene umuyaga usohoka.

Umutwe w'Icyuma c'Ivyuma vyinshi-
Mu gukurikirana gufyonda ounce yose y’ububasha buva muri moteri, abahinga barahindukiriye umutwe w’icylindre ufise -valve nyinshi. Mu buryo butandukanye n’imiterere ya kera y’amavalve abiri-, imitwe y’amavalve menshi-ifise amavalve atatu, ane canke mbere atanu kuri cylindre, bivanye n’ingene itunganijwe.

Umutwe w'Icyuma
Umutwe w’igisenge c’inzu ufise izina ryawo kubera ukuntu giteye, kikaba gisa n’igisenge c’inzu giteye nk’igisenge. Iyi nzira iboneka kenshi mu moteri ziri mu murongo-zine-, aho umwanya ugabanutse. Igishushanyo c’ipentroof kiratuma habaho uburyo bukomeye ariko bukora neza bw’amavalve n’amabuye y’umuriro.

Umutwe w'Icyuma c'Imirongo Ibiri (DOHC)
Ushingiye ku nyungu z’umugambi wa OHC, umutwe w’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara ry’ibarabara. Mu ntunganyo ya DOHC, uzosanga hariho ama camshafts abiri, imwe ikaba ari iyo kugenzura ama valve y’inzira y’amazi, iyindi ikaba ari yo yonyene igenzura ama valve y’amazi asohora. Izo camshafts zikora zidakora, zituma umuntu ashobora kugenzura neza valve no guhindura igihe. Ivyo bituma umuntu ashobora mbere kumenya neza igihe n’ugucungera neza ivy’ivalve.
