HEI-RUA
Ko te kupu huringa rua-whiu te tikanga ka hanga e te miihini te mana im-pulse ia wa ka heke te piston ki raro.Ko te tikanga he rua nga tauranga o te puoto, he waahanga ranei, kotahi (e kiia ana ko te tauranga whakauru) hei whakauru i te ranunga hau me te wahie, ko tetahi hei tuku i nga hau wera kia rere ki te hau.Ko enei tauranga ka kapi, ka hurahia e te piston i a ia e neke whakarunga ana ki raro.
Ka neke whakarunga te piston, ka noho korehau te waahi e nohoia ana i te taha o raro o te poraka miihini.Ka rere te hau ki roto ki te whakaki i te koretake, engari i mua i te kuhu ki roto, me haere ma te ngota e kiia nei ko te carburetor,
i reira ka kohia e ia nga pata wahie.Ka panaia e te hau he kopa whakarewa puna ki runga i te kohao i roto i te pouaka crankcase ka uru te wahie ki roto ki te pouaka crankcase.
Ka heke te piston ki raro, ka panaia e ia ki runga i te rakau hono me te crankshaft, me te ranunga hau-wahie hoki, ka kopeke tetahi wahi.I tetahi wa, ka hurahia e te piston te tauranga whakauru.Ko tenei tauranga ka ahu mai i te
te pouaka crankcase ki te rango i runga ake i te piston, ka tuku i te ranunga wahie hau kōpeke i roto i te crankcase kia rere ki roto i te cylinder.
Inaianei me titiro tatou ki tetahi huringa hiko i roto i te 1-2, ka tiimata mai i te piston i te waahanga iti rawa o tana whiu ki runga-a-raro i roto i te rango.Kei te rere te ranunga hau me te wahie ka timata ki te turaki i nga hau wera
ki waho i te tauranga whakapau, ka hura hoki.

 

Ka timata te piston ki te neke ake, i te wa kotahi ka oti te mahi ki te pana i nga hau remu kua tahuna ki waho o te tauranga ngongo, me te kopiri i te ranunga hau-wahie i roto i te rango.Ka tae te piston ki runga o te
rango, kei te hipoki te piston i nga tauranga e rua, me te ranunga hau-wahie ka tino paopao.I tenei wa ka puta mai he korakora, he miro ki roto i te ruma ngingiha, ka mura te ranunga.Ko te nui ake o te pupuhi, ka nui ake te kaha o te pahūtanga, me te nui ake o te pehanga whakararo o te piston.
Ka pehia te piston ki raro, ka whakawhiti i te kaha ma te rakau hono ki te crankshaft, ka huri.Ka hurahia e te piston whakararo te tauranga ngongo, katahi ka timata ano te tauranga whakauru
he mahi whakakopeke i te ranunga hau-wahie i roto i te pouaka crankcase, kia kaha te rere ki roto i te rango o runga.
Ahakoa ko te nuinga o nga miihini e rua-huringa e whakamahi ana i te kakaho kakaho, e kiia nei he kakaho, i roto i te pouaka crankcase, kaore etahi o nga miihini.He tauranga tuatoru kei a ratou, ka hipokina, ka hurahia e te piston, ka taea e te ranunga hau me te wahie kia rere ki roto
kua kore i roto i te pouaka crankcase i hangaia e te piston neke whakarunga.Tirohia te 1-3.
