He aha te mita rere hau waka
Ko te pūoko rere hau, e mōhiotia ana ko te mita rere hau, tētahi o ngā pūoko nui i roto i ngā miihini werohanga wahie hiko. Ka hurihia e ia te rere o te hau e manawahia ana hei tohu hiko, ka tukuna ki te waeine whakahaere hiko (ECU), e mahi ana hei tētahi o ngā tohu taketake mō te whakatau i te werohanga wahie, ā, he pūoko hoki mō te ine i te rere o te hau e manawahia ana ki roto i te miihini.
I runga i tētahi taputapu werohanga wahie e whakahaerehia ana e te hiko, ko te pūoko e ine ana i te nui o te hau e manawahia ana e te mīhini, arā, ko te pūoko rere hau, tētahi o ngā wāhanga nui e whakatau ana i te tika o te whakahaere o te pūnaha. Ina tohua te tika o te whakahaere o te ōwehenga hau-wahie (A/F) o te hau me te ranunga e ngongohia ana e te mīhini ki roto ko ±1.0, ko te hapa e whakaaetia ana o te pūnaha ko ±6% ki te 7%. Ina tohatohahia tēnei hapa e whakaaetia ana ki ia wāhanga o te pūnaha, ko te hapa e whakaaetia ana o te pūoko rere hau ko ±2% ki te 3%.
Ko te ōwehenga o te rere hau whakauru mōrahi ki te iti rawa o te miihini penehīni, mōrahi/min, he 40 ki te 50 i roto i te pūnaha manawa ā-taiao, me te 60 ki te 70 i roto i te pūnaha turbocharged. I roto i tēnei awhe, me taea e te pūoko rere hau te pupuri i te tika ine o te ±2 ki te 3[%]. Ko te pūoko rere hau e whakamahia ana i roto i te taputapu werohanga wahie e whakahaerehia ana e te hiko, kaua e pupuri noa i te tika ine i roto i te awhe ine whānui, engari me tino pai te urupare ine, me kaha ki te ine i te rere hau e pupuhi ana, ā, me ngāwari te tukatuka i te tohu putanga.
E ai ki ngā āhuatanga rerekē o te pūoko rere hau, ka whakarōpūtia te pūnaha whakahaere wahie ki te mana whakahaere momo-L e ine tika ana i te rahinga whakauru me te mana whakahaere momo-D e ine ā-kore ana i te rahinga whakauru i runga i te tikanga ine o te rahinga whakauru. Ka ine ā-korehia te rahinga whakauru i runga i te pēhanga kino o te manifold whakauru me te tere o te miihini. I roto i te aratau whakahaere momo-D, ka rongoa mua te ROM rorohiko iti i te rahinga hau whakauru i raro i ngā āhua rerekē me te tere miihini me te pēhanga i roto i te paipa whakauru hei tawhā. I runga i te pēhanga me te tere whakauru i inehia i ia āhua whakahaere me te whakamahi i te rahinga hau whakauru e maumahara ana ki te ROM, ka taea e te rorohiko iti te tatau i te whakapaunga wahie. Ko te mita rere hau e whakamahia ana i roto i te mana whakahaere momo-L he rite tonu ki te pūoko rere ahumahi whānui. Heoi, ka taea e ia te urutau ki te taiao uaua o ngā motuka, engari me aro atu hoki ki ngā huringa ohorere o te rere ina pēhia te whakateretere me te hiahia kia kitea te tino tika i roto i te rere koretake i puta mai i te āhua o ngā manifold whakauru i mua me muri i te pūoko.
Kāore i whakamahia e te pūnaha whakahaere werohanga wahie hiko tuatahi ngā rorohiko iti. Engari, he ara iahiko anaro. I taua wā, i whakamahia he pūoko rere hau momo takirere, engari i te whakamahinga o ngā rorohiko iti hei whakahaere i te werohanga wahie, ka puta mai anō ētahi atu momo pūoko rere hau.
Ko te hanganga o te pūoko rere hau momo takirere.
Kei runga i te mīhini penehīni te pūoko rere hau momo takirere, i waenganui i te tātari hau me te pūwero. Ko tana mahi he kite i te nui o te hau e tomo ana i roto i te mīhini, ā, ka huri i ngā hua kitenga hei tohu hiko, ka whakaurua ki roto i te rorohiko iti. E rua ngā wāhanga o tēnei pūoko: he mita rere hau me te potentiometer.
Tuatahi, me titiro tātou ki te tukanga mahi a te pūoko rere hau. Ka tere te hau e kumea ana e te tātari hau ki te takirere. Ka mutu te takirere i te tūranga e taurite ana te rōrahi whakauru ki te puna whakahoki. Arā, he rite tonu te nui o te whakatuwheratanga o te takirere ki te nui o te whakauru. Kua tāutahia hoki he potentiometer ki te pou hurihuri o te takirere. Ka huri tahi te ringa reti o te potentiometer me te takirere. Ka whakamahia te maturuturunga ngaohiko o te ātete reti hei huri i te nui o te whakatuwheratanga o te pereti ine hei tohu hiko, ka whakaurua ki te ara iahiko whakahaere.
Pūoko rere hau vortex Kaman
Hei whakakore i ngā ngoikoretanga o te pūoko rere hau momo takirere, arā, hei whakawhānui i te whānuitanga ine me te whakarite i te tika o te ine me te whakakore i ngā hononga reti, kua whakawhanakehia he pūoko rere hau iti, māmā hoki, arā, ko te pūoko rere hau vortex Karman. He āhuatanga ā-tinana te vortex Karman. Kāore he pānga o te tikanga kimi o te vortex me te ara iahiko whakahaere hiko ki te tika o te kimi. Ko te horahanga o te ara hau me te huringa rahi o te pou whakaputa vortex te mea e whakatau ana i te tika o te kimi. Waihoki, nā te mea ko te putanga o tēnei momo pūoko he tohu hiko (auau), ina whakauru ana i ngā tohu ki te ara iahiko whakahaere o te pūnaha, ka taea te waiho he kaitahuri AD. Nō reira, ko te tikanga, he tohu e tika ana te pūoko rere hau vortex Karman mō te tukatuka rorohiko iti. E toru ngā painga o tēnei pūoko: te tika o te whakamātautau, te kaha ki te whakaputa tohu raina, me te tukatuka tohu ngāwari; Kāore te mahi e rerekē ahakoa te whakamahinga roa. Nā te mea he mea mō te kimi i te tere rere rōrahi, kāore he take ki te whakatika i te pāmahana me te pēhanga hau.
Ina puta he awhiowhio Karman, ka rerekē me te rerekētanga o te tere me te pēhanga. Ko te kaupapa matua o te kite rere ko te whakamahi i te huringa o te tere i roto. Ko ngā tohu he ngaru tapawhā me ngā tohu matihiko. Ko te nui ake o te rōrahi whakauru, ko te teitei ake o te auau o te awhiowhio Karman, ā, ko te teitei ake o te auau o te tohu putanga o te pūoko rere hau.
Ko te pūoko rere hau whakaōrite pāmahana me te pēhanga te mea e whakamahia nuitia ana mō te ine rere o ngā momo pāpāho i roto i ngā paipa ahumahi, pērā i te hau, te wai, te mamaoa, me ētahi atu. Ko ōna āhuatanga ko te iti o te ngaronga pēhanga, te whānuitanga ine, te tino tika, ā, kāore e pāngia e ngā tawhā pērā i te kiato wai, te pēhanga, te pāmahana me te matotoru i te wā e ine ana i te tere rere rōrahi i raro i ngā āhuatanga mahi. Kāore he wāhanga miihini e neke ana, nō reira he tino pono, ā, he iti noa te tiaki e hiahiatia ana. Ka taea e ngā tawhā taputapu te noho pumau mō te wā roa. Ka whakamahia e tēnei taputapu ngā pūoko ahotea piezoelectric, he tino pono, ā, ka taea te mahi i roto i te awhe pāmahana mahi mai i te -10℃ ki te +300℃. He tohu paerewa anaro me ngā tohu pao mamati e puta ana, kia ngāwari ai te whakamahi tahi me ngā pūnaha mamati pērā i te rorohiko. He tere rere matatau, he pai hoki.
Ko te painga nui o ngā pūoko rere hau ko te kore e pāngia te tauwehenga taputapu e ngā āhuatanga ā-tinana o te reo inehia, ā, ka taea te whakawhānui mai i tētahi reo noa ki tētahi atu reo. Heoi, nā te rerekētanga nui o ngā awhe tere rere o te wai me te hau, ka rerekē rawa hoki ngā awhe auau. I roto i te ara iahiko whakakaha mō te tukatuka i ngā tohu tiriti vortex, he rerekē te awhi whakawhiti o te tātari, me ngā tawhā ara iahiko. Nō reira, kāore e taea te whakamahi i te tawhā ara iahiko kotahi hei ine i ngā atanga rerekē.
