Freightliner Cascadia Evolution: Ngā Āhua o te Whakamātautau me ngā Huinga Hāngā Mātauranga

Ko te Cascadia Evolution a Freightliner e whakamāhinga ana i ngā āhuatanga o te whakamāhua i ngā tāwhai rere kia pai ake te whakamāhua i ngā waka rere tāwhai. Kua mahi i ēnei mahi mātauranga ki te ara o te hau e rere mai ana i ngā waka nui nei. Ko ngā āhuatanga o te waka ko ngā kōpae āhua, ā, ngā pūrere iti i runga i te tuanui, ngā pānā o te tāwhai i te tāwhai, me ngā rākau e whakamāmā i te wāhi i waenganui i te waka me te waka tāwhai. I tēnei katoa, ko ngā āhuatanga o te whakamātautau i ngā āhuatanga o te hau e whakamāmā i te hau i te 15% i te whakamāhua i ngā tau kua pahure, ā, i tā SAE. I tēnei whakamātautau i te motō Detroit DD15, ka whakamāhinga i ngā pukapuka GPS me ngā kōrero mō te whenua kia whakamāhinga i te hāere o te waka i te wāhi e taea ana, ā, kia tū tonu te motō i ngā RPM iti. Ka whakamārama ngā kaiwhakamāhi i te whakamāhua i ngā utu rere i te 10% i tēnei hanga. Ko ngā wāhanga aluminium i te waka katoa, tātai hoki ngā rākau rere e māmā ake te rere, e whakamāhinga ana i ngā whakamāhua. Kua kitea e ngā kamupani tāwhai nui i ngā waka o rātou e tāwhai ana i te 7.2 ki te 8.1 mīra i te galone i ngā hāpua rere rere, ā, he mātua rawa te kitea i ngā piko o ngā maunga. Heoi anō, hei whakamāmā i ngā mahi kia tika, he whakamāmā tonu i ngā āhuatanga o te hau me ngā whakamāmā i ngā āhuatanga o te hau, ā, ko ngā mahi whakamāmā nei he wāhanga o ngā whakamātautau a Freightliner mō ngā kaiwhakamāhi.

Kenworth T680 Advantage tātai whakamātautau i te whakamātautau o te whakamāhi i te kōpū hiko i te ao pūrākau vs. Peterbilt 579

Ko ngā T680 Advantage o Kenworth me ngā Peterbilt 579 he rerekē ngā whakamātautau, engari e rua nei ngā waka tāwhai i te whai hua pai rawa i te diesel. Ko ngā āhua o te T680 ko te whare kāpae mātātoko, ngā pākākā kōpū kaha, me ngā tapa roa, ā, ānei ngā āhua e āki ana i te tāwhai i te 7 ki te 8 mīhini i te gālone i ngā whakamātau tāwhai roa. I tēnei anō, ko te pūnaha whakamātautau awhina e whakamārama ana i te hinga o te hiko i ngā whakamātautau. I te tuarua, ko te 579 he āhua āna, pērā i tana upoko rorohiko, ngā kākahu āwhina i ngā tapa hei whakamātautau āwhina, ā, he waka e rere ana i te mōhini PACCAR MX-13 e whakamārama ana i te whakamātautau. Ko ēnei waka e tāwhai ana i ngā tauira ōrite i te tāwhai, ā, e whakamāmao ana i te whakamātautau o te mōhini i te wā iti i te 18%, ā, he rongoā mai i ngā whakamātau EPA SmartWay. I te whakamātau i ngā waka tāwhai SmartWay certified, e rua ngā tauira e tāwhai ana i ngā tauira o te rāngai i te 12 ki te 15%. He aha te mea nui? Ko te āhua o te whakamāhi a ngā kaiwhakamāhi i a rātou. Ko ngā rōpū e whakamāhi ana i ngā kaiwhakamāhi i ngā mahi pērā i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i te whakamāhi i......

Ngā Tārua Hāere Āwhina Āhua Hōu: Ngā Whakamātautau Ūkui, ngā āhuatanga o te whakamāhi

Tesla Semi: Ngā Whakaahua mō te MPGe, ngā here o ngā rākau whakauru hiko, me ngā whakamāngō i ngā kaha o te tārua

I tā Tesla whakamārama, ka taea e tēnei Semi haere i te rōrahi o ngā mīle 500 i tēnei wā i tāwhai i tēnei kaha i ngā āhuatanga tino pai i runga i ngā whakamātautau o te 2024 EPA. Ko ngā tau o te MPGe e whakaatu ana he whakamāhi i te hiko i te rōrahi o te 2.5 i te iti ake i ngā waka tukutuku diesel tūturu. Engari, he pērā ngā take i te wā e tāwhai ana ngā waka nei i ngā ara tūturu. Ko ngā pākete hiko mātua e whakamāmā i te wāhanga o ngā mea e whakamāhi ai i te 15 ki te 20 ōrau, ā, he nui ngā whāinga mō ngā kamupani e whakamāhi ana i te tātai i runga i te tāmata, i te wāhanga rānei o ngā taonga. He hāngā hāngā āwhina hāngā 750V ngā wāhi whakamāhi hiko, engari ko ngā wāhi e 200 anō noa i te katoa o te whenua i tēnei wā, i runga i ngā raraunga o te Tari Hiko o te Tāone o Amerika mai i te 2024. Ā, anō hoki, he 45 meneti te wā e tāwhai ai i te 80 ōrau o te whakamāhi hiko, ā, he toru ngā wā te iti ake i te wā e whakamāhi ai i te tākoha diesel. Ko tēnei wā atu e whakamānui ana i ngā ara e hiahiatia ana te whakamāhi tūturu i waenganui i ngā tāwhai. Ko ngā whakamāhi he pai i te paparanga i te $0.25 i te mīle i te whakamāhi i ngā utu hiko, engari ko te whakamāhi i tēnei i te āhua o te moni he whāinga nui o te whakamāhi i tēnei waka i ia rā. Ko ngā kamupani i whakamāhi i tēnei i mua i kite i ngā putanga pai ake i ngā haerenga iti i raro i ngā mīle 300 i reira e whakamāhi ai i ngā wāhi whakamāhi hiko o rātou i ia wā.

Volvo VNL Electric me ngā Tāwhai eMV o Navistar: Ngā Hāere Ā-Regiona me ngā Whaiwainga o te Whakamāngō i te Pūhanga

Ngā Hāngā o te Hoahoa me ngā Mahi e Whakamāhua ana i te Pakaru o te Rere o ngā Waka Hāngā

Te Āhua o te Rere, te Whakamātātari i ngā Waka Tāwhai, me ngā Pūkenga o ngā Kaiwhakamāhi i te Tāwhai o te Rere

I ngā hāere i ngā huarahi tūmatanui, ko te whakamāngō o te āki ā-hau he nui ake i te haurua o ngā mahinga kaha e whakamahinga ana ngā waka, ā, ko tēnei i tā SAE International i whakamātau i te tau 2022. Hei whakamāmā i tēnei whakamāngō, me titiro ngā kamupani ki tō rātou katoa te whakamāhinga o te kāpae me te pākete waka. Ko ngā mea pērā i ngā kāpae o runga, ngā kāpae tāwhai i ngā tapa o te kāpae, ā, ngā kāpae whakamāmā i ngā wāhi wāhi i waenganui i ngā waka, me ngā whakawhitinga o muri (boat-tail) e whakamāmā ai te whakamāngō o te āki ā-hau, ā, i āhua hāere tonu pea te whakamāmā i te āki ā-hau, i āhua 25% pea. Ā, ko tēnei e whakamāmā ai te whakamāhinga o ngā mīra i ia galone. He hiranga hoki te whakamāhinga tika o te waka. Inā he rahi ake i ngā inchi e rua te wāhi wāhi i waenganui i te tuanui o te waka me te tuanui o te waka, ka whakapāngia te āki ā-hau, ā, ka pakaru te kaha, ā, pea he 3–7% te pakaru kaha, ā, ko tēnei i tā SmartWay. Engari, ahakoa kua whakamahinga ngā taputapu tika katoa, ko ngā kaiwhakamāhi anō hoki he wāhi nui. Ko ō rātou tikanga e whakamāhinga ana i te kaha e 30% pea. Ko ngā kaiwhakamāhi e whakamāhinga ana i te kaha, e whakamāhinga ana i ngā hāere i raro i te 65 mph i ngā wā e taea ana, me te whakamāhinga pai i te rārangi haere, ka tātai ai i ngā whakamāmā mai i te 10–20%. Ko ngā kamupani e whakamahi ana i ngā rārangi whakamāhi mō ō rātou waka, e whakamāhinga ana i ngā kōrero whakamātautau i te wā, i taea nei te whakamāmā i ngā wā kore mahi o te waka i te toru hauā, ā, ko tēnei e whakamāmā ai te kaha e toru hauā o te galone i ia hāora e whakamāhinga ana te waka.
