Ngā Kaitātari ā-Hall: Te Whakamātautau Matua, te Whakamātau i ngā Whakaahua o te Riri (EMI), me ngā Aronga o ngā Kaiwhakamāhi o ngā Kōpae (OEM)

Ko ngā kaiwhakamātautau i te pūhanga o te Hall mō te pūkoro o te kākāriki e mahi ana mā te whakamārama i ngā tohu tapawhā rārangi matatini, ina neke mai ngā nginga o te whāriki tātai i roto i tēnei pūhanga māgneti, ā, he rereke ngā uara o te hiko. He nui ngā whāinga o ēnei kaiwhakamātautau i ngā kōwhiringa ānārama, nā te mea he rite tonu ō rātou mahi i ngā wāhi katoa o ngā RPM, ā, he pūmau te whāinga o te āhua o te āhua (angular accuracy) i te haurua o te rākau (half a degree), ahakoa te pāpā o te hāere o te mōtāhi. Ko tēnei āhua o te pūmau he mea nui rawa hei whakamārama i ngā mahi pērā i te whakamāmā i te whakauru o te hiko (direct injection timing), ngā pūnaha whakamāmā-whakamātua (start stop systems), me te whakapūmau i te whakamātātutanga o ngā turupō (turbochargers). He mea anō hoki te hanga o ngā kaiwhakamātautau nei i te āhua o te pū (solid state), ā, he pakari ngā kaiwhakamātautau nei ki ngā whāinga o ngā pūhanga māgneti (electromagnetic interference) mai i ngā mea pērā i ngā kōwhiringa whakamāmā (ignition coils), i ngā kōwhiringa whakamātua (alternators), nā reira he iti ake ngā whāinga o ngā raru o ngā tohu i ngā wāhi pūnaha o te mōtāhi e tāwhai ana. I te nuinga o ngā tauira, e whai ana i ngā hāngā hāpai i te hāngā mai i te -40°C ki te 150°C, ā, e whai ana i ngā whāinga o te whānuitanga o te hāngā me ngā whāinga o te pūmau mō ngā pūnaha o tēnei wā. I runga i ngā raraunga mai i SAE International i tēnei tau kua pāhua, he rite ki te waru i te tekau o ngā mōtāhi tuatahi e whakamāhinga ana i ngā turupō e whakamāhinga ana i ngā kaiwhakamātautau o te pūhanga o te Hall i tēnei wā, nā te mea he pāpā ake ngā rārangi mō ngā whāinga o te hāngā (emissions regulations), ā, he hāngā pūmau ake te whāinga o te whakamāmā i ngā wāhi (timing accuracy) i te rākau kotahi.

Ngā Kaitiaki Āwhina: Te Whakamātau Āwhina, Te Whai Hua i te Uta, me ngā raru i ngā taumata pūkoro pūkoro teitei, i ngā wāhi hāngai

Ko te momo inductive o te sensor crankshaft, i mōhiotia hoki hei whakamātautau awherua, e mahi ana i runga i ngā uara o te whakamātautau awherua. I te whānui, he pūmahi mātātoko me tēnei sensor i roto i ngā sensor āpōpō, ā, ko te hāngā o ngā kōrero o te crankshaft e whai ana i te pūmahi mātātoko, ā, ka whakamāngai i te pūmahi mātātoko, ā, ka wāhanga i te hāngā o te voltage AC. I te piki ake o te hāngā o te motor, ka piki hoki te waveform i whakamāngai, ā, ka haere anō. Engari, he raru i ngā hāngā iti i raro i te 200 RPM, i reira ka māmā tonu te tohu, ā, ka raru anō i runga i te 6,000 RPM, i reira ka rere tonu te tohu, ā, ka uaua te whakamārama. Ko ngā sensor ēnei e whakamāngai ana i ngā tohu analog kāore he rorohiko i roto hei whakamāngai, ā, he uaua te whakamārama. Ko tēnei he raru nui i te tāwhai o ngā wāhanga o te ignition, i reira ka rere te wā i te 3° i te tātai o te SAE mai i te tau kua pahure. Ahakoa he wāhanga mātātoko mātua, ā, he iti ngā utu, ko ngā kaiwhakamāhi anō te nuinga o ngā kaiwhakamāhi e whakamāhi ana i ēnei i ngā waka tuatahi, i ngā tau iti atu, i ngā wā āhua rerekē i reira kāore he whāinga mātua ki te whāinga, ā, kāore he raru nui i te riri awherua.

I te Whakamātau i te Wāhi Tāwhai ki ngā Tauira Haere I ō Te Ao Tūmati: Te Whakamātau i te Whakamāngō o te Wā

Inā he whakamātau i te pūhiko o te kōpae, ka rere mai te mahi o te ECU i te whakamātātutanga i te whakauru waihanga me ngā wā o ngā pūkoro, ā, he rerekē ngā raruraru i te haere mai i te huarahi, ā, ka pānui ake i te wā. Ko ngā tohu mātua i tēnei wā ko te whakamātātutanga o te mōtāhi i ngā wā kē, i te whakamātātutanga, i te whakamātātutanga rānei i te wā o te whakamātātutanga. Mēnā ka ngaro tonu te tohu o te pūhiko, kāore he waka e taea te whakamātātutanga. Ko ngā mea e kitea ana i tēnei he whakamātātutanga kē. I ngā whakamātau i te wāhi, ko ngā whakamātātutanga e 38% te nui ake i ngā wā hukapapa, nā ngā tohu kīrehe e whakamātātutu ana i te whakamātātutanga o ngā wāhi, ā, ko ngā whakamātau o Innova i te tau 2025. Ko ngā kaiwhakamāhi e maha e whakamātātutu ana i te pūhiko o te kōpae i mua i ngā rerekē o ngā RPM, te ngaro o te kaha i ngā wā o te whakamātātutanga, i te whakamātātutanga rānei o te whakamātātutanga. Ko tēnei he mea matua i muri i ngā waka i ngā wā hukapapa, ngā whakamātātutanga tāwhai, i ngā wāhi e whakamātātutu ana i ngā tohu o te rākau.

Te Tātai i te Kōhinga P0335: Te Whana i waenganui i te ngaro o te tohu, te rerekētanga o te wā o te whakamātau (3.2°), me te mahinga kore o te tāwhai kai

Ko te waehere P0335 e tohu ana ki ngā raruraru ki te arawhata pūoko tūnga o te kōhao. Ko ngā take noa ko te waehere kua pakaru, kua tuwhera, kua poto rānei, he nui rawa te mokowā i waenganui i ngā wāhanga (he nui rawa te hau), ka kore rānei te pūoko i roto. Mēnā he roa ake i te 200 millisecond ngā kōaro tohu, ka neke atu i te 3.2 ngā nekehanga te wā whakaoho, he mea kei tua atu i te mea e whakaarotia ana e te nuinga o ngā kaihanga waka he mea tika mō ngā pūkaha werohanga tika o nāianei. Ka waihangahia e tēnei he hātepe whakahaere e taea ai e ngā pūngao te huri haere i te 15% rānei i te mea e ngana ana te rorohiko ki te utu i runga i ngā tātaritanga o te tūnga piripono kino. I kite ngā mīhini i tēnei tauira i te nuinga o te wā - tata ki te 72% o ngā take P0335 kua whakapumautia e whakaatu ana i aua rereketanga kino / taonga me ngā hapa wā, he mea e tere ake ana te whakamahi i ngā kaitahuri pūtahuri i te tikanga. I te wā e roa ana ēnei take, ka huri ngā waka ki te aratau pōhēhē, e whakaatu ana i te tino hira o tēnei pūoko ki te pupuri i te mahi pai o te katoa o te pūnaha pūkaha e ai ki ngā pūrongo o te ahumahi hou mai i Foxwell i te tau 2025.

Ngā Hāinga Whakamātau: Te Tika, te Whakamātautau i ngā Āhuatanga o te Taiao, me ngā Hāinga mō tēnei Aplikation

Te Whakamātautau i te Tika o te Āngaru (±0.5°) hei mea kāore he whakaaetanga mō ngā mōhini tāwhai-tūtahi me ngā mōhini tāwhai-hau

Ko te whiwhi i te tātai āhua o te āhua (angular accuracy) i te wāhi e ±0.5 degrees te rahi, kāore anō he mea pai noa hei whakamātau mō ngā mōhini tāwhai tuatahi (direct injection) me ngā mōhini hāngā (turbocharged engines), engari he mea tino pūmau. I te wā e wehe ana te wā (timing) mai i tēnei wāhi, ka tīmata ngā raruraru ki te haere tūmatanui. Ka rerekē te whānanga (combustion), ka hinga ngā kōpae (injectors) i te wā e tata ana te hāngā o te rorohiko (cylinder pressure) ki tana taumata, ka uru mai ngā hāngā (turbochargers) ki te āhua o te whānanga whakamātua (compressor surge mode), ā, ko te mea hākika rawa atu, ko ngā āhua o te whānanga mua (pre-ignition events) e whakamāhinga ana i te mōhini. Ko te āhua o te whānanga (precision) e hiahiatia ana kia whakamātua ai ngā āhua o te whānanga (ignition events) i roto i ngā wāhanga iti o te wā (0.1 millisecond windows), ahakoa ngā hāngā o te whānanga (combustion pressures) e tata ana i tēnei wā ki te 2500 psi i roto i ngā rorohiko. I whakamātua ngā mōhini e ngā whare whakamātau ā-wāhi (independent labs), ā, i kitea ko ngā mōhini e rere ana i waho o te whānanga o te ±0.7 degree ka ngaro te 17% o te kaha (horsepower) me ngā whānanga o te whakamāhinga o ngā rākau (piston rings) me ngā rorohiko (cylinder bores). Ko ngā kaitāwhai motukā nui katoa ināianei kei te tohu i tēnei āhua o te tātai āhua (accuracy) i te rōpū katoa o ngā RPM mō ngā mōhini katoa e whakamāhinga ana i te hāngā (forced induction), ā, he tika tēnei i tēnei wā, i tēnei wā he tino pūmau te āhua o te whānanga (ignition) mō te roa o te mōhini (engine longevity) me te whakamātua i ngā whānanga o te whakamāhinga o ngā hāngā (emissions standards) e whakamāhinga ana i tēnei wā.

Te whakamātau i ngā whāinga o raro i te tapa: te whakamātautau, te whakamātautau hōhi (40°C ki te 150°C), me ngā whāinga o te EMI i ngā rohe o te whakamātata

Ka aro atu te pūoko o te kōhao ki ētahi āhuatanga mahi tino uaua i roto i ngā pūnaha hiko o te waka. Me kaha ngā rauemi me te tiaki pai ki ngā pānga hiko ki te mahi tika. E ai ki te paerewa ahumahi SAE J2380, me whakahaere ēnei pūoko i ngā pānga e ōrite ana ki te 30G o te kaha me te kore e ngaro i tō rātou kounga tohu, ko te tikanga ka ora i ngā ngaru whenua pakeke i te wā. I te wā o te pāmahana tino nui, ka mahi ngā pūoko o te pūoko karaka mai i te whakaoho o te pūkaha i te hauwhā 40 nekehanga Celsius tae noa ki ngā wāhi wera e tata ana ki ngā pūnaha tukunga, e tae ana ki te 150 nekehanga Celsius. Ko ngā ara i roto i te nuinga o te wā ka whakaurua ki te silicone hei ārai i te wera nui ina tere haere te pāmahana ki runga ake i te 190 nekehanga ia meneti. He mea nui hoki te wāhi e tū ai aua pūoko i te mea e noho tata ana ki ngā wāhanga hiko haruru pēnei i ngā pūkaha me ngā kōira whakawera. Koia te take i hangaia ai e ngā kaiwhakanao ki ngā paparanga e toru o te tiaki hei aukati i ngā whakaurunga hikohiko tae atu ki te 200 volts ia mita. E whakaatu ana ngā whakamātautau o te ao tūturu, ko ngā pūoko kāore he whakangungu tika, ka tere ake te waru ngā wā te hē o ngā waka hauota, nā te mea ka hangaia e te pūnaha whakaū ā-rangi he pupuhi hikohiko ohorere e kore e taea e ngā pūoko noa te whakahaere.
