He aha ngā pānga ki te motuka mēnā ka pakaru te pūoko o te camshaft?
Ka raru pea te whakaoho mīhini i te pūoko camshaft kua pakaru, ka wiri i te wā e whakamahia ana, ka heke te mana, ka nui ake te kai wahie, ā, ka puta pea he rama whakaoho hapa.
Ngā Whakaoho me ngā Āhuatanga Rerekē o te Mīhini
Te uaua ki te tīmata me te whakakā pōrearea: I muri i te pakaru o te pūoko, kāore e taea e te ECU te whakatau tika i te āhua o ia rango me te wāhanga camshaft, ka hua ake he pōrearea o te wā whakakā, e whakaatuhia ana ko te hiahia kia maha ngā ngana ki te tīmata, te whakaroa rānei i te tīmatanga, te kore rānei e taea te tīmata. I ngā take kino, i te wā o te tīmatanga, tera pea ka puta he huringa o te crankshaft me te hokinga whakamuri o te manifold whakauru.
Te hekenga o te pumau o te noho mangere me te mahi:
Wiri nui o te noho puku: He rite ki te tohu o te kore e mura te miihini, he mārama te wiri.
Te maha o ngā wā e tū ana te mīhini i te wā e taraiwa ana: Ina koa i te wā e whakamahana ana, ka tū pea te waka i te wā e taraiwa ana, e whakakī ana rānei i te hinu.
Te urupare whakatere puhoi: Whai muri i te takahi i te whakatere, ka mutu te whakaputanga mana, ā, i te nuinga o te wā, me neke ake te tere o te miihini i te 2500 rpm hei whakapai ake.
Te Hekenga o te Mahi Pūngao me te Whakaora Wahie
Hekenga nui o te putanga mana: Nā te korenga o te ECU e whiwhi i ngā tohu wāhanga camshaft tika, kāore e taea te tukutahi i te werohanga wahie me te wā mura ki te mahi o te rango, ka hua ake he ngoikore o te miihini, he puhoi te whakatere, me te puhoi o te urupare i te wā e piki ana, e hipa ana rānei. Tērā pea ka whakawhāitihia e te ECU o ētahi tauira te tere mōrahi o te miihini hei tiaki i te miihini.
Te pikinga ake o te whakapaunga wahie me te tukunga: Kāore i te tika te whakahaere a te ECU i te werohanga wahie, ka nui rawa te werohanga wahie, ka kore rānei e tika te werohanga wahie, ā, ka piki ake pea te whakapaunga wahie i inehia mā te 15%-30%. I taua wā anō, ka puta he paoa pango mai i te paipa putanga hau mēnā kāore i oti te tahunga, ka nui ake te haunga putanga hau, ā, ka piki ake pea te kawenga ki te pūoko hāora me te kaitahuri whakatere toru-ara, me te mōrearea o te kino i te wā roa o te mahi.
Te Tiakitanga Pūnaha me ngā Mōrearea Ā-Mīhini Pea
Te whakahohenga o te aratau tiaki hapa: Kei te kā tonu te rama hapa o te miihini (e rite ana ki ngā waehere hapa pēnei i te P0340), ā, ka uru te ECU ki te aratau, ka whakawhāiti i te putanga mana, ā, ka whakakore pea i ngā mahi pēnei i te wā takirere rerekē (VVT). I tēnei wā, ka taea e te waka te haere i ngā tawhiti poto noa iho, engari he tino iti te mahi.
Ngā tūponotanga kino ā-mīhini pea:
Te hē o te wā mura: Ka pā te pahūtanga, ā, i roto i te wā, ka pakaru te rango, te piston, me ētahi atu wāhanga.
Te pikinga ake o te pakaru o te tikanga takirere: Kāore e taea e te ECU te whakahaere tika i te wāhanga takirere, ka nui ake pea te pakaru o ngā wāhanga miihini e pā ana.
Mēnā he nui rawa ngā wā ka hē te pūoko o te porowhita hurihuri, ka kore pea te waka e tīmata, e tū rānei i te wā e whakamahia ana.
Kei waenganui i te rama-whakaputa rama (LED) me te transistor whakaahua-hiko (photodiode rānei) te kōpae tohu. Ina huri te kōhao tuku rama i runga i te kōpae tohu i waenganui i te LED me te transistor whakaahua-hiko, ka whiti te rama e tukuna ana e te LED ki runga i te transistor whakaahua-hiko, ā, i taua wā ka rere te rama o te transistor whakaahua-hiko, ā, ka puta te rama iti (0.1-0.3V) i tana kaikohi; ina huri te wāhanga atarangi o te kōpae tohu i waenganui i te LED me te transistor whakaahua-hiko, kāore e taea te whiti te rama e tukuna ana e te LED ki runga i te transistor whakaahua-hiko, ā, i taua wā ka mate te transistor whakaahua-hiko, ā, ka puta te rama teitei (4.8-5.2V) i tana kaikohi. Mēnā ka huri tonu te kōpae tohu, ka whakawhiti te kōhao tuku rama me te wāhanga atarangi i waenganui i te LED me te transistor whakaahua-hiko, ā, ka whakawhiti te kaikohi o te transistor whakaahua-hiko ki ngā taumata teitei me ngā taumata iti. Ina huri te rakau pūoko me te poro crankshaft me te poro cam valve, ka haere te kōhao tuku mārama me te wāhanga atarangi i runga i te kōpae tohu i waenganui i te LED me te transistor photoelectric, ka whiti te mārama e tukuna ana e te LED ki runga i te transistor photoelectric o te kaihanga tohu, ā, ka whakaputa te pūoko tohu i ngā tohu pāhekoheko e rite ana ki te tūranga o te poro crankshaft me te tūranga o te poro cam valve.
I te mea e rua ngā hurihanga katoa o te porowhita hurihuri, ka whakaputahia e te pūoko tohu G he 6 ngā tohu pāorooro. Ka whakaputahia e te pūoko tohu Ne he 360 ngā tohu pāorooro. Nā te mea ko te pewa wāwāhi o te kōhao tuku mārama o te tohu G he 60. Mō ia 120 nekehanga o te hurihanga o te porowhita hurihuri, ka whakaputahia he tohu pāorooro. Nō reira, ka kiia te tohu G ko te tohu 120. Mā te hoahoa me te tāutanga ka whakarite kia whakaputahia te tohu 120. 70. (BTDC70.) i mua i te pokapū mate o runga o te rango miihini. Ko te tohu i whakaputaina e te whakatuwheratanga tapawhā rite me te taha whānui roa ake e rite ana ki te 70. 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. I te mea ko te tawhiti i waenganui i te kōhao tuku mārama mō te tohu Ne he 1. (0.5 te kohao tuku mārama, ā, 0.5 te kohao atarangi), i ia huringa pāorooro, ka nohoia e ngā taumata teitei me ngā taumata iti he koki hurihanga 1. o te toki porowhita, ā, ko ngā tohu 360 e tohu ana i te hurihanga 720. o te toki porowhita. Ia hurihanga 120. o te toki porowhita, ka whakaputahia e te pūoko tohu G tētahi tohu, ā, ka whakaputahia e te pūoko tohu Ne he 60 tohu.
