1. Tautanga mowhiti piston:

Ko te mowhiti piston tohu ka taea te whakauru ki te piston i muri i te tirotiro. Me aro nui ki te waahi whakatuwhera me te ahunga o te mowhiti i te wa e whakauruhia ana. Ko te tikanga, he pere whakarunga, he tohu TOP ranei kei te taha o te mowhiti piston. Me whakanoho tenei mata ki runga. Mena ka huri ke, ka kore e wera te hinu; Me whakarite kia whakanekehia nga waahi tuwhera o nga mowhiti mai i a raatau (te nuinga o te 180 ° mai i tetahi atu) Ka tohatohahia, i te wa ano, kia kore e rite te whakatuwheratanga ki te waahi o te kohao pine piston; ka whakamahia nga taputapu motuhake i te wa e whakauruhia ana ki runga i te piston, kaore i te tūtohuhia te whakauru a-ringa; kia whai whakaaro ki te whakauru mai i raro ki runga, ara, whakauruhia te mowhiti hinu i te tuatahi, katahi ka whakauru i te Ringa hau tuarua, he mowhiti hau, kia tupato kia kaua e waiho te mowhiti piston kia pakaru te paninga o te piston i te wa o te whakaurunga.

2. Kua whakauruhia te huinga hononga piston ki runga i te miihini:

Horoia rawatia te riipene rango i mua i te whakaurunga, ka pania he kahu angiangi o te hinu miihini ki runga i te pakitara rango. Hoatu etahi hinu miihini ki te piston me te whakakai piston me te rakau hono e mau ana i te ngahere, katahi ka whakamahi i tetahi taputapu motuhake hei kopaki i te mowhiti piston me te whakauru i te whakahiato pou hono ki roto i te miihini. Whai muri i te whakaurunga, whakamauhia te wiri rakau hono kia rite ki te taipana kua tohua me te tikanga whakamau, ka huri i te crankshaft. Ko te crankshaft e hiahiatia kia huri noa, me te kore e kitea te stagnation, me te aukati hurihuri me kaua e nui rawa.
