Icyitegererezo cyingirakamaro gitanga gahunda ya tekiniki ikurikira: compressor ihuza ikirere itagira amavuta igizwe na crankcase, crankshaft ihinduranya mukuzunguruka, impera imwe ya crankshaft ihujwe na moteri, urundi ruhande rwa crankshaft rwashyizweho hamwe umufana, blokte yo kwishyiriraho ihuriweho hejuru yigitereko, silinderi ishyizwe kumurongo wimbere, piston yumuyaga ucyeye itunganijwe muri silinderi, hanyuma piston iratwarwa kandi igahuzwa na crankshaft, Crankcase ni silindrike , umufana uherereye muri crankcase kandi ni coaxial hamwe na crankcase, blokte ya mitingi ihabwa umwobo uyobora ikirere cyo gukonjesha urukuta rwinyuma rwa silinderi, umwobo uyobora ikirere uhujwe nu mwobo w'imbere wa crankcase no hejuru ubuso bwahagaritswe, urukuta rwuruhande rwa silinderi rutangwa nubushyuhe, hashyirwaho umuyoboro wo gukwirakwiza ubushyuhe hagati yumuriro wubushyuhe nurukuta rwinyuma rwa silinderi, nu mwobo uyobora ikirereni guhangana n'umuyoboro wo gukwirakwiza ubushyuhe.

Ibyatoranijwe mubyitegererezo byingirakamaro: silinderi ni umuzenguruko, umuhanda uzamuka ni urukiramende, hagati yikibanza cyo guhagarara gitangwa na silinderi ihuza umwobo, umwobo uyobora ikirere uherereye kumpande zombi z'umwobo uhuza, hamwe nuyobora ikirere umwobo utangwa na stiffeners.

Icyitegererezo cyingirakamaro nibyiza bifite ibyiza bikurikira: uburebure bwurukuta kumpande zombi zuyoboye ikirere bingana.

Ibyatoranijwe muburyo bwingirakamaro ni uko igikonjo na silinderi bikozwe muri aluminium.

Ugereranije nubuhanzi bwabanjirije iki, ingaruka zingirakamaro zingero zingirakamaro ni uko igikonjo ari silindrike, umufana uherereye muri crankcase na coaxial hamwe na crankcase, kandi umufana ashyirwaho kumpera imwe yigitereko.Iyo igikonjo kizunguruka, piston yo gutwara irazamuka ikamanuka muri silinderi kugirango ihoshe umwuka.Muri icyo gihe, umuyaga ushyizwe kuri crankshaft nawo uzunguruka hamwe kugirango utange umwuka, Umuyaga uhuha ukonje urukuta rwo hanze rwa silinderi unyuze mu mwobo uyobora ikirere.Ikariso ni silindrike.Ugereranije na crankcase y'urukiramende, trapezoidal nubundi buryo, kurwanya biterwa numuyaga mwinshi ni bito.Umufana uherereye muri crankcase na coaxial hamwe na crankcase.Intera kuva kumpera yinyuma yumufana kugeza kurukuta rwimbere rwikariso irasa kandi yoroshye kugenzura murwego ruto, rushobora kuzamura umuvuduko wimyuka yumuyaga, Urukuta rwinyuma rwa silinderi rwakonje neza, kandi umwobo uyobora ikirere uhujwe neza no gukwirakwiza ubushyuhe bwa silinderi

Umwuka uhumeka utangwa nabafana urashobora gukoreshwa cyane mugukonjesha urukuta rwinyuma rwa silinderi.
