Mahi pūoko pēhanga whakauru waka
Ko ngā mahi matua a te pūoko pēhanga hau whakauru waka ko ēnei āhuatanga e whai ake nei:
Whakarato tohu kawenga miihini : Ka tukuna e te pūoko pēhanga whakauru te tohu kawenga miihini ki te ECU (Wāhanga Whakahaere Miihini) mā te ine i te huringa pēhanga i roto i te manifold whakauru. Ka āwhina ēnei tohu i te ECU ki te whakahaere tika i te whānui o te pā o te werohanga me te whakatuwheratanga o te throttle kia pai ai te mahi miihini me te penapena wahie .
Whakahaere i te werohanga wahie me te wā mura : Ka hurihia e ngā pūoko ngā huringa pēhanga i roto i te manifold whakauru hei tohu hiko mā te ECU hei whakatika i te koki werohanga wahie me te wā mura. Ina piki ake te kawenga o te miihini, ka heke te pēhanga i roto i te manifold whakauru, ka piki ake te tohu putanga o te pūoko, ā, ka whakanuia e te ECU te nui o te werohanga wahie me te whakaroa i te koki whakamua o te mura. Ki te kore, ka whakaitihia te werohanga wahie, ā, ka nekehia te mura .
Whakatikatika i te wā whakatuwheratanga o te takirere whakauru me te werohanga wahie : I roto i tētahi mīhini me te pūnaha whakahaere takirere hiko, ka kitea e te pūoko pēhanga whakauru te huringa pēhanga i roto i te paipa whakauru, ā, ka tatau tika i te rōrahi hau i roto i ia rango hei whakatikatika i te wā whakatuwheratanga o te takirere whakauru me te rōrahi werohanga wahie. Ka āwhina tēnei ki te whakapai ake i te whai huatanga me te putanga mana o te mīhini .
tiaki i te miihini : Ka taea hoki e te pūoko pēhanga whakauru te kite i ngā āhuatanga mahi rerekē o te miihini, pērā i ngā huringa pēhanga rerekē, me te tuku tohu ki te pūnaha whakahaere hei tiaki i te miihini. Ka āwhina tēnei ki te ārai i te kino o te miihini nā te taumaha rawa, nā ētahi atu raruraru rānei .
Mātāpono Mahi : Ko te pūoko pēhanga whakauru ka honoa ki te pūoko whakauru mā te ngongo korehau, ā, ka rongo i te huringa korehau i roto i te pūoko whakauru. I te huringa o te tere me te kawenga o te miihini, ka rerekē te pēhanga i roto i te pūoko whakauru, ā, ka rerekē anō hoki te ātete i roto i te pūoko, ka puta he tohu ngaohiko. Ka whiwhi te ECU i tēnei tohu, ā, ka whakamahia hei whakarite i te werohanga wahie me te wā mura.
Pānga hapa : Ki te pakaru te pūoko pēhanga whakauru, ka arahi pea ki te tere kore pumau, te whakaterenga ngoikore, te uaua ki te tīmata, te pikinga o te whakapaunga wahie me ētahi atu raruraru o te waka. I taua wā anō, ka tahuna te rama hapa o te miihini, ā, ka rongoatia te waehere hapa e rite ana.
Nō reira, he mea nui te tirotiro me te tiaki i te pūoko pēhanga whakauru i ia wā, kia pai ai te mahi a te waka.
He wāhanga nui te Pūoko Pēhanga Mutunga (MAP) i roto i te miihini motuka e aroturuki ana i ngā huringa pēhanga i roto i te manifold whakauru, ā, ka hurihia ēnei huringa hei tohu hiko kia tika ai te whakahaere mā te waeine whakahaere hiko (ECU) o te miihini. Ka honoa te pūoko pēhanga whakauru ki te manifold whakauru mā te ngongo korehau, ā, ka taea te rongo i te huringa korehau i roto i te manifold whakauru. Mēnā he rerekē te tere me te kawenga o te miihini, ka rerekē te ātete i roto i te pūoko, ka hurihia hei tohu ngaohiko mā te ECU hei whakatika i te nui o te werohanga wahie me te wā mura.
Te kaupapa mahi
Ko te kaupapa whakahaere o te pūoko pēhanga whakauru e ahu mai ana i te huringa ātete i puta mai i te huringa pēhanga. Hei tauira, tangohia te pūoko pēhanga whakauru momo varistor, ko tōna wāhanga matua he diaphragm silicon i hangaia mai i te pānga piezoresistive o te semiconductor. Ina pā te pēhanga o te manifold whakauru ki te diaphragm silicon, ka rerekē te diaphragm, ka hua ake he huringa i roto i tōna uara ātete. Ka hurihia tēnei huringa hei tohu hiko, ka whakanuia, ka tukuna ki te ECU. I runga i te ngaohiko tohu i whiwhihia, ka whakahaere tika te ECU i te werohanga wahie taketake kia rite ki ngā hiahia taraiwa rerekē.
Ngā momo me ngā tono
He maha ngā momo pūoko pēhanga whakauru, ko ngā mea noa ko te varistor semiconductor, te bellows korehau me te capacitive. I roto i ēnei, he whānuitia te whakamahinga o te varistor semiconductor i roto i te pūnaha werohanga momo-D nā te mea he tere te urupare, he tino tika, he iti te rahi me te ngāwari o te tāutanga. Ka whakamahia e te pūoko capacitive te diaphragm hei hanga i tētahi huānga tairongo pēhanga me te uara capacitance rerekē, ā, ka hurihia te huringa pēhanga hei tohu hiko mā te ine i te ara iahiko.
Te tiaki me te tautuhi hapa
Ko te tātaritanga hapa o te pūoko pēhanga whakauru ko te tirotiro mēnā kei roto i te awhe noa te tohu putanga. Mena he rerekē te tohu putanga o te pūoko, tera pea ka heke te mahi a te miihini, ka kore rānei e pumau. I te wā tiaki, tirohia te hononga me te hiri o te pūoko i ia wā kia tika ai te mahi.
