Urutoki rw'urutoki rw'urwasaya runini rukoreshwa na Pistons ebyiri, buri piston ihujwe n'urutoki na roller na hyperboloid kugirango ikore igice kidasanzwe. Menya ko intoki zihora zigenda hejuru yikigo, kandi buri rutoki ntirushobora kumenwa ryigenga. Niba urutoki rugenda muburyo bunyuranye, Piston yabagabwe mbere irahindurwa kandi izindi piston irasuzumwa. Hano haribintu bibangikanyeho ubwoko bwumuyaga mwinshi hamwe nubunini bufite imbaraga zibangikanwa no gufunga ubwoko bwikirere.
Uburyo bwibikorwa byurutoki rwintoki.
Inzozi zo gufungura no gufunga zigenwa hakurikijwe imiyoboro itandukanye ya silinderi: 4, 6, 10, 14, 14, 22, 30mm.
Imbaraga zishimangiwe zimigabane ibiri yintoki zigabanijwemo: imbaraga zo hanze za diameter ni 3.3n kugeza 254n; N'imbaraga z'imbere zidasanzwe ni 6.1n kugeza 318n.
Urutoki rusanzwe Cylinder Cyliser na Byihariye ni: Ibikorwa-bikora MHZ2
Ubwoko bwa silinderi ibangikanye byigabanyijemo: Umuhengeri usanzwe; muremure mu buryo bworoshye umwuka; hamwe nigituba cyumukungugu
