He aha te wira tohu o te crankshaft motuka?
Ko te wira tohu o te toki porowhita o te motuka, e mōhiotia ana ko te pūoko tūranga o te toki porowhita, ko tōna mahi matua ko te aroturuki i te tere me te koki o te toki porowhita o te miihini, kia tika ai te whakatau i te tūranga o te toki porowhita. Ka tukuna ngā raraunga kua kohia ki te Wāhanga Whakahaere Miihini (ECU) me ētahi atu pūnaha rorohiko e tika ana kia tika ai te whakahaere i te wā mura o te miihini.
Te kaupapa mahi
Ko te wira tohu o te porowhita he mea hanga i te nuinga o te wā hei wira me ngā niho maha. Ina haere te wira tohu mā te pūoko, ka puta he ngaohiko AC, ā, ka rerekē te auau o tēnei ngaohiko me te huringa o te tere. Mā tēnei hoahoa ka taea e te pūoko te ine i te tere o te miihini mā te whakamahi i te tohu pā.
Momo me te wāhi tāutanga
E ai ki te kaupapa whakaputa tohu, ka taea te wehewehe i te wira tohu o te porowhita crankshaft ki ngā momo e toru: te momo aukume, te momo whakaahua-hiko, me te momo Hall. Ko ngā pūoko Hall noa e whakamahi ana i te hoahoa waea-toru, tae atu ki te taura hiko, te taura tohu AC me te taura tiaki tohu AC. Ko te wāhi tāutanga kei roto i te tohatoha, i runga i te whare mamau tuku, i te pito o mua, o muri rānei o te porowhita crankshaft, me ētahi atu, i runga i te momo pūoko me te hoahoa miihini.
Mahi tahi me ētahi atu wāhanga
Ko te wira tohu o te crankshaft e mahi tahi ana me te pūoko tūranga camshaft hei whakatau i te wā mura taketake. Mā te whakarato i ngā mōhiohio tūranga tika, ka whakarite kia taea e te miihini te mahi i runga i te raupapa mura kua whakaritea, kia pai ai te mahi, kia maeneene hoki.
Ko te mahi matua o te wira tohu o te toki porowhita o te motuka he kite i te tere me te koki o te toki porowhita o te miihini, te whakatau i te tūranga o te toki porowhita, me te tuku i ngā hua kua kitea ki te waeine whakahaere miihini (ECU) me ētahi atu pūnaha rorohiko e tika ana kia tika ai te whakahaere i te wā mura o te miihini.
Ina koa, ko ngā mahi a te wira tohu o te crankshaft (e mōhiotia ana ko te pūoko tūnga o te crankshaft, ko te pūoko tere rānei o te miihini):
Tirohia te tere o te miihini: Whakatauhia te āhua mahi o te miihini mā te kimi i te tere o te porowhita.
Whakatauhia te tūranga TDC o te piston : Tāutuhia te tūranga TDC o ia piston rango. He mea nui tēnei mō te whakahaere i te wā mura me te wā werohanga wahie. Hei tauira, ka taea e ia te whakarato tohu TDC takitahi o te rango hei whakahaere i te mura me ngā tohu TDC o te rango tuatahi hei whakahaere i te werohanga wahie raupapa.
e whakarato ana i te tohu koki o te toki porowhita : Mā te kimi i te koki o te toki porowhita, kia tika te wā whakakā o te miihini me te wā werohanga wahie.
mahi tahi me te pūoko tūranga camshaft : I te nuinga o te wā ka mahi tahi me te pūoko tūranga camshaft hei whakarite kia tika te wā mura taketake o te miihini. Ka whakatauhia e te pūoko tūranga camshaft ko tēhea piston rango kei te whiu kōpeketanga, ko te pūoko tūranga crankshaft ia ka whakatauhia ko tēhea piston rango kei te TDC .
Hei tāpiritanga, ko ngā āhuatanga hoahoa o te wira tohu porowhita he wira me ngā wāhanga niho maha. Ina haere te wira tohu mā te pūoko, ka puta he ngaohiko AC e rerekē ana te auau me te tere.
