He aha te mahi a te pūoko camshaft o te waka?
He taputapu mōhio te pūoko tūnga camshaft, e mōhiotia ana ko te pūoko tohu tukutahi. He taputapu tautuhi tūnga rango e whakauru ana i te tohu tūnga camshaft ki te ECU, ā, koia te tohu whakahaere matua mō te whakahaere mura.
Ngā Āhuatanga Hanganga
Ko ngā pūoko tūnga porowhita hiko me te porowhita kame i hangaia e Nissan he putanga whakapai ake o ngā kaituku. Ko te nuinga o ēnei he kōpae tohu (arā, te rotor tohu), he kaihanga tohu, he kaituku, he whare pūoko, me te hononga taura waea.
Ko te kōpae tohu te hurihuri tohu o te pūoko, ā, ka pēhia ki te kakau pūoko. I te taha tata ki te kōpae tohu, e rua ngā mowhiti porowhita o ngā kōhao tuku mārama me ngā āputa ōrite. I roto i ēnei, e 360 ngā kōhao tuku mārama (缝隙) o te mowhiti o waho, me te pewa āputa o te 1. (Ko ngā kōhao tuku mārama he 0.5, ā, ko ngā kōhao atarangi he 0.5.) Ka whakamahia ēnei hei whakaputa tohu koki hurihuri me te tere o te toki porowhita; e 6 ngā kōhao tuku mārama (ngā kōhao tapawhā) o te mowhiti o roto, me te pewa āputa o te 60, hei whakaputa tohu pokapū mate o runga o ia rango. I roto i ēnei, kotahi te kōhao tapawhā he taha roa ake te whānui, hei whakaputa tohu pokapū mate o runga o te rango 1.
Kei runga i te whare pūoko te kaihanga tohu. Kei roto ko te kaihanga tohu Ne (tohu tere me te koki hurihuri), he kaihanga tohu G (tohu pokapū mate o runga), me te ara iahiko tukatuka tohu. Ko ngā kaihanga tohu Ne me te tohu G he mea tito mai i te LED me te phototransistor (photodiode rānei), me ngā LED e rua e anga atu ana ki ngā phototransistor e rua. Te mātāpono mahi
Ka tāutahia te kōpae tohu ki waenganui i te diode tuku mārama (LED) me te transistor whakaahua-tairongo (photodiode rānei). Ina huri te kōhao tuku mārama i runga i te kōpae tohu ki te tūranga i waenganui i te LED me te transistor whakaahua-tairongo, ka whiti te mārama e tukuna ana e te LED ki runga i te transistor whakaahua-tairongo. I tēnei wā, ka rere te transistor whakaahua-tairongo, ā, ka whakaputa tana kaikohi i te taumata iti (0.1 - 0.3V). Ina huri te wāhanga atarangi i runga i te kōpae tohu ki te tūranga i waenganui i te LED me te transistor whakaahua-tairongo, kāore e taea te whiti te mārama e tukuna ana e te LED ki runga i te transistor whakaahua-tairongo. I tēnei wā, ka tapahia te transistor whakaahua-tairongo, ā, ka whakaputa tana kaikohi i te taumata teitei (4.8 - 5.2V).
Ki te huri tonu te kōpae tohu, ka huri te kōhao tuku mārama me te wāhanga whakamarumaru i te LED kia mārama, kia atarangi rānei. Ka huri te kaikohi o te transistor whakaahua-tairongo i ngā taumata teitei me ngā taumata iti. Ina huri te pou pūoko me te toki porowhita me te pou kamepa wā takirere, ka huri te kōhao tuku mārama me te wāhanga whakamarumaru i runga i te kōpae tohu i te LED. Ka whiti te mārama e tukuna ana e te LED ki runga i te transistor whakaahua-tairongo o te kaihanga tohu nā te pānga tuku mārama me te atarangi o te kōpae tohu. Nō reira, ka whakaputaina he tohu pāhekoheko e rite ana ki te tūranga o te toki porowhita me te pou kamepa wā takirere i roto i te pūoko tohu.
I te mea e rua ngā hurihanga o te porowhita hurihuri, ka panaia e te porowhita pūoko te kōpae tohu kia huri i te porowhita kotahi. Nō reira, ka whakaputahia e te pūoko tohu G ngā tohu pāoro e 6. Ka whakaputahia e te pūoko tohu Ne ngā tohu pāoro e 360. Nā te mea he 60 nekehanga te pewa wāwāhi o te kōhao tuku mārama o te tohu G, ka whakaputahia he tohu pāoro i ia 120 nekehanga o te hurihanga o te porowhita hurihuri. Nō reira, ka kiia te tohu G ko te tohu 120. Mā te whakaurunga hoahoa ka whakarite kia whakaputahia te tohu 120 i te 70 nekehanga i mua i te pokapū mate o runga (BTDC70). Ko te tohu i whakaputaina e te kōhao tuku mārama me te whānui tapawhā roa ake e rite ana ki te 70 nekehanga i mua i te pokapū mate o runga o te rango 1 o te miihini, kia taea ai e te ECU te whakahaere i te koki whakamua werohanga wahie me te koki whakamua mura. Nā te mea he 1 nekehanga te pewa wāwāhi o te kōhao tuku mārama o te tohu Ne (he 0.5 nekehanga te noho o te kōhao tuku mārama, ā, he 0.5 nekehanga te noho o te kōhao atarangi), i ia huringa pāoro, ka nohoia e ngā taumata teitei me ngā taumata iti te kotahi koki porowhita hurihuri. E tohu ana ngā tohu 360 i te hurihanga o te 720 nekehanga o te porowhita. Ia 120 nekehanga o te hurihanga o te porowhita, ka whakaputahia e te pūoko tohu G tētahi tohu, ā, ka whakaputahia e te pūoko tohu Ne e 60 ngā tohu.
