Peratra piston
Ny peratra piston dia amboarina ary sokajiana araka ny fiasa sy ny fampiasana azy.Ny fampiasana voalohany ny peratra piston dia ny famehezana ny efi-trano (izay ihetsehan'ny piston), izay mety ho efitrano fandoroana amin'ny motera 2 na 4 stroke.Ny motera an-dranomasina dia manana karazana peratra telo na maromaro napetraka eo amin'ny manodidina ny piston.
Ny tahirin-tsarimihetsika dia mifanaraka amin'ny fanatsarana ara-teknika tany am-boalohany.Izahay dia manome peratra piston mifono tany am-boalohany (indrindra fa ny ALU COAT (TOP RING)) toy ny DAROS, NPR, PP sy ny sisa, mety amin'ny modely misy ny MC, MC-C, ME-C, FLEX (RTA48T-B，RT-FLEX50- D，RT-FLEX50-B，FLEX RTA58TB，5RT-FLEX58T-D，RTA48T-B，RTA68T-B sns.), andiany RTA, sns.
Ho fanampin'ireo peratra voarakotra etsy ambony, dia mitahiry peratra tsy misy fonony ihany koa izahay.Tsy misy coated peratra varotra manokana, ny lisitra manokana dia toy izao manaraka izao:
