NGĀ TAIPITOPITO O TE HUA
whakaahuatanga hua
1. Te Whai Hua: Ko ngā miihini 4-whiu he nui ake te whai huatanga o te wera i ō rātou hoa 2-whiu nā te mea he uaua ake, engari he pai ake te huringa tahunga. Ka hurihia e rātou he ōrau nui ake o te pūngao wahie hei mahi whai hua, ka hua ake he pai ake te penapena wahie me te iti ake o ngā utu whakahaere i roto i te wā.
2. Te whakaiti i ngā tukunga: Mā te huringa 4-whiu ka taea te tahu pai ake o te wahie, ka āwhina i te whakaiti i ngā tukunga hau kino pērā i te hauota waro (CO), ngā hauwaiwai kāore i tahuna (HC), me ngā waikura hauota (NOx). Ehara i te mea ka pai ake te taiao, engari ka taea hoki te whakatutuki i ngā ture tukunga kaha i roto i te maha o ngā whenua.
3. Te iti o te whakamahinga hinu: He rerekē ngā miihini 2-whiu, e hiahia ana kia whakaranua te hinu ki te wahie, kia werohia tika rānei ki roto i te rūma mura, he pūnaha whakahinuhinu motuhake tā ngā miihini 4-whiu. Ka wehea te hinu mai i te wahie, ka whakaiti i te whakapaunga hinu, ā, ka roa ake te ora o te miihini. Ka hua ake hoki he hau putanga ma, ā, ka kore e hiahiatia te whakawhiti hinu pinepine.
4. Mahi maeneene: Mā te huringa 4-whiu, me ōna huringa whakauru, kōpeketanga, mana, me te putanga hau motuhake, ka maeneene ake, ka marino ake te mahi ki te whakataurite ki ngā miihini 2-whiu. Ka pai ake te wheako o te kaiwhakamahi, inā koa i roto i ngā mahi pēnei i ngā motuka me ngā motopaika.
5. Te pakari me te pono: He iti ake ngā wāhanga neke me te hoahoa māmā ake i ngā miihini tīhiera, he māmā ake, he iti ake, he ngāwari ake hoki te tiaki i ngā miihini penehīni 4-whiu. He roa hoki te wā e mau ana, e pono ana hoki, inā koa ka tiakina tika.
6. Whānui te whānuitanga o te mana: Ka taea te hanga i ngā miihini penehīni 4-whiu hei whakaputa i te whānuitanga o ngā putanga mana, mai i ngā waeine iti, māmā mō ngā taputapu kari me ngā kuta ki ngā miihini mahi teitei mō ngā motuka hākinakina me ngā tono reihi. Nā tēnei whānuitanga o te whakamahinga ka pai ai mō ngā momo ahumahi me ngā hiahia o te kaiwhakamahi.
7. Te wātea me te utu tika o te wahie: He whānuitia te wātea o te penehīni puta noa i te ao, ā, he iti ake te utu i te wahie tīhiera, i ngā pūtake pūngao rerekē rānei pērā i te hau māori kōpeke (CNG) me te hiko. Nā tēnei ka waiho ngā miihini penehīni 4-whiu hei kōwhiringa e pai ana mō te tini o ngā kaihoko me ngā pakihi.
8. Te whakaurunga hangarau matatau: He maha ngā whanaketanga hangarau e whai hua ana mō ngā miihini penehīni 4-whiu hou, pērā i te werohanga wahie hiko (EFI), te wā takirere rerekē (VVT), te werohanga tika, te turbocharging, me ngā pūnaha ranu. Ka whakarei ake ēnei hangarau i te mahi, te whai huatanga, me ngā tukunga, ka tino whakataetae ngā miihini 4-whiu i te mākete o ēnei rā.
