Me pēhea te Whakaiti Whakaiti Mirumiru e Whakaiti ai i te Whakamaumahara Mirumiru?

Me pēhea te mahi a ngā kaituku kora me tā rātou tūwānanga ki te pāmahana pātai

Te Mahi Tuatahi a ngā Kaituku Kora ki ngā Mōhini Hōu

Ko ngā inihana kora pūngao e mahi ana i te tino whakahaere tika e whai hua ana i ā raatau tohutohu mai i te waihanga whakahaere mōhini, te ECU māmā noa. Ka tāia e kē atu ngā karu iti rawa o te kora pūngao ki roto i ngā tatau tāwhai, kaua ko ngā karu ki te kātata ake. Ko te mea nui ko te rerekētanga mai i ngā karu tātā ake o mua. Ā, ēnei ngā inihana hou ka taea te whakarereke i te rahi o te kora pūngao e puta mai ana, me te āhua o te āhua e rite ki te huarahi e hia hoki te wā ia hēkona. Ka pā atu ēnei whakarereke ki ngā korero e pā ana ki te tere o te mōhini, ki te kaha o te mahi a te waka, ā, me te rerekētanga o te wāhi noho. Nā te tino whakarereke tēnei, ka pai ake te mahi a ngā waka kaua ko te āhua noa o te taraiwa. Ka toa tonu te mahi ake, ā, ka pai ake hoki te whakamahi i te kora pūngao.

Te Peke Kaha o te Inihana me te Tika o te Tuku Kora Pūngao

Ko ngā pūnaha toto-āwhio kaha e whakahaere ana i ngā mōhini inaoti tūmau i waenganui i te 1,500 ki te 3,000 PSI, ka whakatoa i te kora hau ki roto i ngā tātata iti nei i te rahi o te micron hei waihanga i ngā karu he 5-10 ngakau iti ake i te makawe tangata. Ko ngā kaihoko maha-hōanga e wehe ai te kora hau tōtika ake i ngā hoahoa kotahi-hōanga, e iti ake ai ngā waahi tōkaha pāpaku, he 18-22%, ka pai ake te tōtika o te kaihoko.

Te Wehenga Kora Hau Me Tana Pakaru Ki Te Whakauru Whakauru

Ko te wehenga iti o te kora hau e iti ai i te 30% ngā whakaputanga hāora kāore i te kaihoko, ka whakapai ake i te kaha o te kaha 8-12% (SAE International, 2022). Ko ngā karu iti ka rere ke te wai, e waihanga ana i te hononga hau-kora hau anō rānei e tautoko ana i ngā aronga kaihoko iti - he tino whai hua ina wātea ana te whakahaere i te wā e iti ana te kaha kia mōhiato te kora hau.

Te Whakapai ake i te Hononga Hau-Kora Hau Trūnga Te Whakauru Tika o te Wā Kātata

Ko te tika o te wā pānui ki roto i te 1-2 o te tāwhai pōroto e whakaiti i te pakaru i ngā mōhini turupōroto. Ko te tuku tōrōwhārite, e rite ana ki te rere o te hau o ia silinda, e whakauru ana i ngā ōwehenga hau-motuka ki roto i te ± 0.03 o te lambda 1.0 i raro i te 95% o ngā tikanga mahi, e whakapumautia ana i te kākara tūturu me te rite pai.

Whakauru Tika vs. Whakauru Huarahi Motuka: Whāwhātata i te Mahinga me ngā Whakakaha

Me pēhea te whakauru tika i te motuka (DFI) e whakapai ake i te mahinga motuka

Ko te whakauru māmā hui aratau e mahi ana mā te whakaputu i te kora hui aratau ki te kāmera kaiwhakarewa o te motuka ki raro i te pēhi tino nui, i te wā kotahi e eke ana ki te 3,000 psi. Ko tēnei ka hua ai te wehenga iti ake o te kora, he 20% pai ake i te āhua e kitea ana ki ngā pūnaha whakauru tūranga. Ko te wehenga pai ake ka taea ai ngā motuka te whakahaere ki ngā tauwhātanga pakeke ake hoki. Ina ko ngā whakauru tūranga tuku iho e eke ana ki te 10:1 tauwhātanga, ka taea e te whakauru tīmatanga te eke atu ki te 12:1. E ai ki ngā rangahau hou i 2024 mō te whai rawa kaiwhakarewa, kei te iti ake hoki te kora kāore i te kaiwhakarewa e 9% ki te 15%. A, ina tāpirihia e ngā kaihanga te whakauru māmā hui aratau ki ngā turupō, ka pai ake hoki ngā oranga kora. Kua whakamahia ngā whakamātautau e te EPA kua whakapai ake i te oranga kora ki te 11% ki te 18% i ngā whakamātautau tukutuku tuku iho.

Port fuel injection (PFI) efficiency and reliability benefits

Whakaratia ana ngā punaha PFI i te whakapono tika ake i te roa, e whakauru ana i te 97.8% o ngā waahanga o ngā waahanga i muri i te 100,000 mīni - tino ake ake i te 89.3% o DFI (SAE International, 2023). Kei te arataki ngā kora kai ki runga i ngā taura whakauru e hāngai ana, e here ana i te 83% o te hanga pāpaku kāriroa e pāngia ana hoki ngā punaha DFI, ā, e whakauru ana i te rere o te hau kāore he tino whakahaerenga motuhake.

Te mahi me ngā whakaputanga: DFI vs. PFI ngā whakapiringa o te ao hono

Ko ngā punaha DFI e 6-9% te nui ake o te whakauru o te wera i te wā e haere ana i te tiriti engari he 34% te nui ake o ngā pāpaku itiiti (2.5 µm). I te tuarangi, ko te PFI e whakauru ana i ngā ara whakarewa (EGR) o te hau whakarewa, e iti ake ana i ngā whakaputanga pāpaku 28%, ahakoa ko te 7% he iti ake te kaha ki te rere i ngā RPMs.

Te takotoranga o te ahumoni: Te nui ake o te whakauru ki DFI vs. te nui ake o ngā whakaputanga pāpaku

Ahakoa kei te āki ai te DFI i te whakawhitinga o CO ki te 12% ia kilometre, kei te whakaputangia e ana tikanga kā ngota PM2.5 e 41% atu ake i te PFI. Ina pakari ake ngā tāura whakawhitinga o te ao, me whakapiri ngā kaihanga waka i ngā kāpure huinga parakiru—ka piki ake ngā utu huihuinga ki te $240-$390 ia waka—kia whakakaha tēnei take.

Ngā Kauta Rīwai Kiru, Kiru Hāpūtia: Ngā Pānga ki te Ora o te Kora, ki te Mahi

Me pēhea ngā taapiri e iti ake ai i te kaha o te Kauta Kora, e whakararu i ngā tauira whakaputangia

Ko ngā taapiri karbona mai i te kora kāore i te kounga teitei, i ngā kiru rānei e iti ake ai i te 30% (Kaiwhakawhanake Autōmōhine, 2021). Kātahi ka whakararu ngā here i ngā tauira whakaputanga, ka arahina ki te hanga kōaro kāore i te āhua māro. Ko te iti noa o te kora e āki ai te kāinga, e ono ki te 10-15% (Pukapuka Kaiwhakahaere Waka, 2022).

Ngā Tohu o ngā Kauta Kino: Iti noa te Ora o te Kora, Kaha Kāore, Me ngā Kauta Kāore

Ko ngā kauta kua rīwai he whakaputanga e toru ngā take matua:

• 12-15% te iti ake o te kaha o te kora na te tukatuka hauhake i te urupare ki te kaiwhakamahi korekau
• Te noho pōpōpō rānei te kaha o te inu paraihe mai te tukatuka paraihe korewhaitua ki ngā RPMs pāpaku
• Kātata Kātata me ngā whakapōkai e ai ki ngā mātāpuna hau-huinga paraihe i te wā e whakamahia ana te rereparaihe

Te Pānga o ngā Whakauru Kauta ki te Taurite Hau-Paraihe me te Mahi a te Mōhinu

Ko ngā tauira whakaputanga kua whakarereke i te ECU kia rereke i waenganui i ngā whakatika raihania me te ariu tāpua, e whakapai ake i ngā whakapapa o te hauropi e 20-40% (Pūrongo Kaihoko, 2021). Kua āki ake tēnei whakapapa i te hanga pounamu, e whakaroa ake i te mahi me te iti ake i te ora o te hinu mēnā kāore i te whakatika.

Te whakahaere i te hinu kia pai ai te whakamahi i te hinu

Ngā painga o te parakuihi paraiheanu mā te hinu kia pai ai te whakamahi i te hinu

Ko ngā kaihoko pākoka e iti ai te pāmahana o te 58%, e whakaiti ai i te kaha o te kaihoko (SAE, 2023). Ko te whakamātau pāmahana e whakarewa ana i ngā tauira whakaputanga o ngā kaihoko, e whakatika ana i ngā uaua e ngaro ai te 6-12% o te kaihoko. Ko te Whirihau Tūmau 2024 i kitea ko ngā waka e whai whirihau ana i te tau e rua ka tūmanako ki te 4.2% te kaha ake o te kaihoko i ērā anō.

Ngā Tikanga Whirihau Kua Huihui Katoa hei Whakarere i te Kōhao

1. Whakamahia te kaihoko Top Tier® hei whakaiti i te hanga o ngā kaihoko
2. Whakakapi i ngā kiriata kaihoko i ia 30,000 maero (e rite ana ki ngā tohutohu a te kaihanga)
3. Kaua e whakahaere tonu i raro i te kaupeka kaupeka kia iti ake ai te kaihoko
4. Tango i ngā huarahi hauhautanga o te huarahi (15+ meneti) i ia wiki hei āwhina i te whakakore i ngā kaihoko iti

Ngā Kaihoko Kaihoko me te Whakamātau Pāmahana: Kei te Whakapono Rātou i te Kaupeka?

Ko ngā kaiwhakakaha toa toa e iti ake ai te whakaputanga taapiri 34-41% ina whakamahia ngā hui. E āwhina ana ngā taapiri kia pakari te mahi, ka whakakaha hoki i te wai hoki te whakakaha e 89% o ngā taapiri pāpaku e kore e taea e ngā kaiwhakakaha. E whakamōhiotia ana e te Roopu Mahi Mōhiotia o te Motuka o Aotearoa te whakakotahi i te whakamahi i ngā taapiri mā ngā marama me te whakamahi i te whakakaha o te tohunga i ngā wā e rua i te tau kia pakari ai te tere o te manawa.

Kei te Whakapai ake i te Whakamahinga Manawa ina Whakakapi i ngā Kaituku Manawa?

Ina Mea Tika te Whakakapi: Ngā Kaituku Kua Tino Whakamahia, Kua Pakaru rānei

Ina tīmata ngā kaihoko kora toa ki te pāpaku, ka whakarupea e rātou te ara e kī ana te kora ki te mōhinu māka, ka pā ki te taurite o te hau me te kora. Ko te nuinga o te wā ka hinga te kaha o te kora i te 10 ki te 15 ōrau nā te mea kāore i te katoa te kora e singe. Ko te nuinga o ngā kaitakaro ka kitea e rātou ngā raru tuatahi tru ngā mahi pōpō, ngā wehenga ina hōunautia ana, te wehenga rānei i te mōhinu māka. He tohu tino ata no te mea kāore ngā kaihoko kora e mahi ana ki roto i ngā whakaritenga o te toa. I tētahi wā, ka pakaru noa i te horoi i ngā raru, ina ko ngā waka tawhito ake i te 100,000 mīni. I muri i te nuinga o ngā mīni, ka pakaru ngā kiriata mira, ka ngoikera ngā hononga hiko nā te whakamahinga tata.

Tuhinga Arataki: Nga Oranga Tāpoi i muri i te Whakakapi I Ngā Kaihoko Kora i Ngā Waka Hauanu

Kātā i te tiro ki ngā raraunga mai i ngā waka e 47 nei me te nui o ngā kīromita, i kitea e mātou ko te whakakapi i ngā kōpiko kaukau kua whakapai ake i te ōrau tūmomo kaukau ki te 12% i runga i te tatauranga. Mō ngā waka ki ngā pūnaha kaukau tōrino, i hoki mai te kaha hōiho ki waenganui i te 8 ki te 14. I kitea hoki e ngā mōhini pūkaukau tūroro he pai ake te mahi, kaukau iti ake i te 5 ki te 9% ina whakatū ake i te makariri. Ina whakaurua e ngā toa tā te kōpiko kaukau hou me te tika te whirihau, i whakatika i te aronga o te taumaha hau kaukau i te pakeke 9 ki te 10 take e ai ki te Pūrongo Whakauru Tūmomo a Fleet mai i te tau ki muri. Kua iti ake te 20% o ngā karawhita whara. Nō reira, he aha te tikanga o katoa ēnei? Ko te whakauru tūmatanui pērā i te whakakapi kōpiko he nui te āwherenga mō ngā mōhini tawhito e whawhai ana ki ngā aronga ōrau.
