Te mahi a te wira tohu o te crankshaft.
Ko te mahi matua a te wira tohu porowhita he whakatau tika i te tūranga me te koki o te porowhita, tae atu ki te tere o te miihini. He maha ngā wā ka mahi tahi me ngā pūoko tūranga porowhita hei whakarite kia pumau te mahi a te miihini, kia pai ake ai te mahi. Hei whakarāpopototanga:
Whakatauhia te tūranga o te toki porowhita: Mā te wira tohu o te toki porowhita, mā tōna hoahoa me tōna tūranga motuhake, ka taea e te pūoko te kite tika i te tūranga o nāianei me te koki o te toki porowhita, he mea nui mō te whakahaere i te wā mura me te werohanga wahie.
Te mahi tahi me te pūoko tūnga camshaft: Ka mahi tahi te wira tohu crankshaft me te pūoko tūnga camshaft ki te whakatau i te wā mura taketake. Mā tēnei mahi tahi ka taea te tahu i te mīhini i te wā tika mō te mahi maeneene me te whai hua.
Ko te wira tohu o te toki porowhita e whakamahia whānuitia ana mō te wira tohu niho 60-2, mēnā he wāhanga niho ngaro, mā te pūoko e ai ki te āhua o te niho me te tohu taumata teitei me te iti o te wāhanga niho ngaro hei aromatawai i te wāhanga toki porowhita 1. Mā tēnei hoahoa ka taea e te pūoko te aromatawai tika i te tūranga me te wāhanga o te toki porowhita mā te āhua o te niho me ngā tohu taumata teitei me te iti o te niho ngaro, , ā, ka tutuki ai te whakahaere tika o te āhua o te mahi a te miihini. ko te hoahoa motuhake o te wira tohu toki porowhita, me te tukatuka i te tohu toki porowhita e te ECU ( wae whakahaere hiko), tētahi o ngā hangarau matua hei whakatutuki i te mahi pai me te pumau o te miihini.
Te aro turuki i te tere o te miihini: Ka aro turukihia hoki e te wira tohu o te crankshaft te tere o te miihini, ka tukuna ngā raraunga ki te ECU (wae whakahaere hiko) hei whakahaere tika i te wā mura me te wā werohanga, he mea nui tēnei hei whakapai ake i te pai o te wahie me te whakaiti i ngā tukunga.
I roto i te poto, he wāhanga nui te wira tohu o te crankshaft i roto i ngā miihini hou, e āwhina ana i ngā pūnaha whakahaere miihini ki te arotau i te mahi me te whakarite kia haumaru te mahi mā te whakarato i ngā mōhiohio tika mō te tūranga me te tere.
He aha ngā āhuatanga o te rahunga o te kōpae tohu o te crankshaft?
Ki te kore e mahi te kōpae tohu o te porowhita, ka pāngia te mahi noa o te motuka e ngā pānga e whai ake nei:
Tuatahi, ka tiaho te tohu hapa, koinei te urupare tika a te pūnaha tātaritanga-ā-roto o te waka i muri i te kitenga i te raruraru. Tuarua, i te tīmatanga o te waka, tera pea ka kitea he roa ake te tukanga tīmatanga i te tikanga, nā te mea kei te ngana te miihini ki te tīmata noa mā te pūoko tūnga camshaft, engari nā te hapa o te kōpae tohu, ka aukatia te tukanga tīmatanga. I te wā e taraiwa ana, tera pea ka pāngia te mahi tere ōrite o te waka, ā, kāore e taea te mahi noa. Hei tāpiri, tera pea ka puta he wiri koretake o te miihini, ā, ka puta he paoa mā.
Ko te mahi matua o te pūoko tūranga o te crankshaft he aroturuki i te tere o te miihini, ā, e ai ki ēnei mōhiohio, ka whakatauhia te nui o te werohanga wahie me te koki whakamua o te mura. Mā tēnei ka taea te tahu me te tīmata i te miihini i te wā tino pai, ā, ka whakaitihia te kino o te motuka. Heoi, ina he raruraru kei te papa tohu o te crankshaft, ka pāngia pea tēnei raupapa o ngā mahi aroturuki me te whakatikatika, ka hua ake he mahi kore pumau o te miihini.
Ko te pūoko tūnga o te porowhita crankshaft ka tāutahia ki roto i te distributor, he wāhanga nui tēnei mō te kimi i te tūnga TDC o te piston, nō reira i ētahi wā ka kiia ko te pūoko TDC. Kia rahua tēnei pūoko, me tirotirohia, me whakatika tonu kia kore ai e horapa te rahunga, kia nui ake ai te kino ki te waka.
