Koiri mura.
I te whanaketanga o te miihini penehīni motuka ki te huarahi tere, ōwehenga kōpeketanga teitei, mana teitei, iti te whakapaunga wahie me te iti o te tukunga, kāore i taea e te taputapu mura tuku iho te whakatutuki i ngā whakaritenga o te whakamahinga. Ko ngā wāhanga matua o te taputapu mura ko te koiri mura me te taputapu whakawhiti, e whakapai ake ana i te kaha o te koiri mura, ka taea e te mono mura te whakaputa i te kaha mura e ranea ana, koinei te āhua taketake o te taputapu mura hei urutau ki te mahi a ngā miihini hou.
kaupapa
E rua ngā huinga koiri i roto i te koiri mura, ko te koiri tuatahi me te koiri tuarua. He waea matotoru ake te koiri tuatahi, he waea 0.5-1 mm te roa, tata ki te 200-500 hurihanga; he waea angiangi ake te koiri tuarua, he waea 0.1 mm te roa, tata ki te 15000-25000 hurihanga. Ka honoa tetahi pito o te koiri tuatahi ki te pūtake hiko iti-ngaohiko (+) i runga i te waka, ā, ka honoa tetahi pito ki te taputapu whakawhiti (kaiwawao). Ka honoa tetahi pito o te koiri tuarua ki te koiri tuatahi, ā, ka honoa tetahi pito ki te pito putanga o te raina ngaohiko teitei hei whakaputa i te ngaohiko teitei.
Ko te take e taea ai e te koiri mura te huri i te ngaohiko iti ki te ngaohiko teitei i runga i te motuka he rite tonu te āhua ki te whakawhiti hiko noa, ā, he nui ake te ōwehenga hurihanga o te koiri tuatahi i te koiri tuarua. Engari he rerekē te aratau mahi o te koiri mura i te whakawhiti hiko noa, ko te auau mahi o te whakawhiti hiko noa he 50Hz pumau, e mōhiotia ana ko te whakawhiti hiko auau mana, ā, ko te koiri mura kei roto i te āhua o te mahi pātītī, ka taea te kī he whakawhiti pātītī, e ai ki te tere rerekē o te miihini i ngā auau rerekē o te rokiroki me te tukunga pūngao auau.
Ina whakakāhia te pōkai tuatahi, ka puta he papa aukume kaha huri noa i a ia i te pikinga o te iahiko, ā, ka rongoatia te kaha o te papa aukume ki roto i te matua rino. Ina momotuhia te ara iahiko pōkai tuatahi e te taputapu whakawhiti, ka tere te pirau o te papa aukume o te pōkai tuatahi, ā, ka rongo te pōkai tuarua i te ngaohiko teitei. Ko te tere o te ngaronga o te papa aukume o te pōkai tuatahi, ko te nui ake o te iahiko i te wā e momotu ana te iahiko, ā, ko te nui ake o te ōwehenga hurihanga o ngā pōkai e rua, ko te teitei ake o te ngaohiko i puta mai i te pōkai tuarua.
Momo koiri
E ai ki te ara iahiko aukume, ka wehea te koiri mura ki te momo aukume tuwhera me te momo aukume kati tuarua. Ko te koiri mura tuku iho he momo aukume tuwhera, ā, ko tōna matua rino he mea whakarārangi ki ngā rau maitai silicon 0.3mm, ā, he koiri tuarua me te tuatahi e karapoti ana i te matua rino. Ko te momo aukume kati e whakamahi ana i te matua rino rite ki te Ⅲ e karapoti ana i te koiri tuatahi, kātahi ka takai i te koiri tuarua ki waho, ā, ka hangaia te rārangi aukume e te matua rino. Ko ngā painga o te koiri mura aukume kati ko te iti o te turuturu aukume, te iti o te ngaronga pūngao me te iti o te rahi, nō reira ko te pūnaha mura hiko e whakamahi ana i te koiri mura aukume kati.
Te mura o te mana tau
I roto i te miihini penehīni tere-teitei o ngā motuka hou, kua whakamahia te pūnaha mura e whakahaerehia ana e te tukatuka iti, e mōhiotia ana ko te pūnaha mura hiko mamati. E toru ngā wāhanga o te pūnaha mura: te rorohiko iti (rorohiko), ngā pūoko me ngā kaiwhakaoho mura.
Ina hoki, i roto i ngā miihini hou, ko ngā pūnaha werohanga penehīni me ngā pūnaha mura e whakahaerehia ana e te ECU kotahi, e whai wāhi tahi ana ki tētahi huinga pūoko. He rite tonu te pūoko ki te pūoko i roto i te pūnaha werohanga penehīni e whakahaerehia ana e te hiko, pērā i te pūoko tūranga crankshaft, te pūoko tūranga camshaft, te pūoko tūranga throttle, te pūoko pēhanga manifold whakauru, te pūoko tango pahūtanga, me ētahi atu. I roto i ēnei, ko te pūoko tango pahūtanga he pūoko tino nui e whakatapua ana ki te mura e whakahaerehia ana e te hiko (ina koa te miihini me te taputapu turbocharging hau putanga), ka taea te aroturuki i te tango pahūtanga o te miihini me te nui o te tango pahūtanga, hei tohu urupare hei whakahau i te ECU kia tutuki te mura i mua, kia kore ai te miihini e tango pahūtanga, kia pai ake ai te mura.
E rua ngā momo o te pūnaha mura hiko matihiko (ESA) e ai ki tōna hanganga: te momo tohatoha me te momo kore-tohatoha (DLI). Kotahi noa te koiri mura e whakamahia ana e te pūnaha mura hiko momo tohatoha hei whakaputa i te ngaohiko teitei, kātahi ka tahuna e te tohatoha te mono mura o ia rango i te wā kotahi e ai ki te raupapa mura. Nā te mea ko te mahi whakaweto o te koiri tuatahi o te koiri mura ka mahia e te ara iahiko mura hiko, kua whakakorehia e te tohatoha te taputapu pakaru, ā, ko te mahi tohatoha ngaohiko teitei anake te mahi.
Te mura o ngā puoto e rua
Ko te tikanga o te mura e rua-puoto he kotahi te koiri mura e whakamahia ana e ngā puoto e rua, nō reira ka taea anake te whakamahi i tēnei momo mura i runga i ngā miihini he taurite te maha o ngā puoto. Mena kei runga i te mīhini 4-puoto, ina tata ngā piston puoto e rua ki te TDC i te wā kotahi (ko tētahi he kōpeketanga, ko tētahi he putanga hau), e rua ngā mono mura e whakamahi ana i te koiri mura kotahi, ā, ka mura i te wā kotahi, ko tētahi he mura whai hua, ko tētahi he mura kore hua, ko te mea tuatahi kei roto i te ranunga o te pēhanga teitei me te pāmahana iti, ko te mea tuarua kei roto i te hau putanga o te pēhanga iti me te pāmahana teitei. Nō reira, he tino rerekē te ātete i waenga i ngā irahiko mono mura o ngā mea e rua, ā, kāore te kaha e puta mai ana i te ōrite, ka hua ake he nui ake te kaha mō te mura whai hua, e 80% pea o te kaha katoa.
Whakakā motuhake
Mā te tikanga whakakā motuhake ka tohaina he koiri whakakā ki ia rango, ā, ka tāutahia te koiri whakakā ki runga tonu i te mono mura, ka whakakorea hoki te waea hiko teitei. Ka tutukihia tēnei tikanga whakakā mā te pūoko camshaft, mā te aroturuki rānei i te pēhanga rango kia tika ai te whakakā, he pai mō ngā miihini rango katoa, inā koa mō ngā miihini e 4 ngā takirere mō ia rango. Nā te mea ka taea te whakairi i te koiri whakakā mono mura ki waenganui o te camshaft takirua o runga (DOHC), ka whakamahia katoatia te āputa. Nā te whakakorenga o te raina tohatoha me te hiko teitei, he iti noa te ngaronga o te kawe hiko me te ngaronga turuturu, kāore he kakahu miihini, ā, ka huihuia te koiri whakakā me te mono mura o ia rango, ā, ka tino whakaitihia e te takai whakarewa o waho te pokanoa hikohiko, ka taea ai te whakarite i te mahi noa o te pūnaha whakahaere hiko miihini.
