• Ko ngā kaitirotiro hau hapa ka piki ake ngā whakaputanga e 30-50%
• Ko ngā hapa o ngā kaitirotiro wera ka piki ake ngā whakaputanga NOx e 20%

Mā ēnei kaiwhakarongo e tūhono ana ngā waka hou ki ngā paerewa whakaputanga kaha, i te nuinga i te mahi i te performance.

Te Pānui i te Mārama Taki i te Injini me Ētahi Atu Tohu Whakatūpato i te Papamātā

Ko ngā waka i ēnei rā e horoi ana ki ngā tohu papamātā kia mōhiotia ai ngā kaitakaro ka hekenga tētahi mea ki ngā kaiwhakarongo. Ka pumautia te mārama taki i te inihini, ko te tikanga he iti noa te raru o tētahi kaiwhakarongo. Engari mēnā ka timata te titirotiro, ko te tohu reka mō te raru nui me ngā whakatika tere. E kī ana ngā toa i BeemerPros ko te nuinga o ngā tāngata e kitea ana ko te mārama taki i te inihini kei te pūmau kei te raru anō hoki i te kaiwhakarongo hau o te hau, ā, ko te kaiwhakarongo māmā hoki e ai ki tā rātou tātai tukutuku. Kei te tino whai whakaaro hoki ki ētahi atu tohu whakatūpato. Ko te tohu arataki ake kua tōmuri ki ngā raru o te kaiwhakarongo tere karu, i te wā e tohua ana te whakatūpato hinu ko te kaiwhakarongo hiko hinu e kore e mahi tika ana. Āwhina ēnei tohu i ngā toa kia mōhiotia ai he aha pea te raru kei raro i te takotoranga.

Ngā Tohu Hei Tinihanga o ngā Kaitirotiro Mōhiotia: Te Paunu, Te Whakatakaritanga Kore Pai, me te Iti ake i te Whai Take Kaukau

Ina timata ngā kaitirotiro motokā ki te heke, ka pā tērā ki te arataki i te rere o te waka. Ko te kaitirotiro maha o te hau e hanga ai i ngā hinu ki te paunu ina arataki ana ki te tere iti, ā, mēnā kei te whakawhiti te rongo te kaitirotiro tūnga toto, ka ngaro te mana noa iho ngā kaiwhakamahi ina whakapau ana i te tere. E ai ki ētahi tātaritanga hou mai i te ao tiaki auno, ka taea e ngā motokā me ngā kaitirotiro hau kore e kauaia ana i waenganui i te 12% ki te 18% atu anō hoki te kaukau nā te hē o te rorohiko hinu e hāngai ana ki te whakakī atu i te hau me te kaukau. Ko ētahi atu raru ko te pahu kākākura e tohu ana ki ngā raru ki te kaitirotiro tūnga karu, i te wā e māmā ana te pāpāriu i muri i te pā ki te pēke kaukau, e tohu ana ki te raru ki te kaitirotiro tūnga tapatoru.

Tīmia tīata tātou i te titiro mā te karapoti i ngā rarae katoa me ngā konehine e pā ana ki ngā kaitirotiro. Kia mataara ki ngā mea pērā i te paraihe paru, ngā pakaru o te kārei, i te mea kākāriki e āhua ana ki ngā pito e tohu ana i te 38% o ngā raru katoa e pā ana ki ngā kaitirotiro e ai ki ngā tauāitanga whakatika aunoa mai i te Rōpū Whakatika Aunoa CarCare i te 2023. Me tirotiro ngā kaitirotiro oksihana tinihia no te mea kei tērā wāhi rawa atu ngā rarae ki ngā wāhi hohoro o te pūnaha whakaputa para. Kaua hoki e wareware ngā kaitirotiro rauemi hau nui, e noho ana marino i tētahi wāhi o te wāhi tītoko i reira ka hui te pāpori me te waimarie i te wā roa kore korikori, kia tae mai te raru ki te timata i te mōhinu.

Whakamātautau i te takotoranga o te kaitirotiro oksihana me te urupare ki te pūnaha whakaputa para

Whakamātau ka whakaurua ngā kaiwhakaaro oksikine i roto i ngā tawhiti e tohua ana e te kaihanga mai i te kaiwhakarereke kaiwhakapai (hei tauira, 6-10 piria ki te tōkei). Whakamahia tētahi mīhini hau hei rāwekenga ranei i te wai sapo hei rapu ngā wāhi pūkaha kei te parirau e āwhina ai i ngā panonitanga o te ūnga hau-kai. Ko te whakaurunga tika ka whakarite kia pono ngā ine i ngā uara lambda e matua herekore ana mō te whakahaere i ngā putanga.

Te ine i te volta me te whakatūpato i ngā porowhita kaiwhakaaro hau maha ki tētahi mīhini volta

Whakamātau i te mahi a te kaiwhakaaro MAF mā:

• Te whakatakoto i ngā mīhini volta ki te aratau volta DC (te kupenga ON/injini OFF)
• Te tirotiro mō te volta tuhuratanga 12V ki te wiri mana
• Te tirotiro i ngā panonitanga volta waitohu i waenganui i te 0.5V (noho) me te 4.75V (WOT)
