Kungani Amaloli Asekhaya Engawakhombi Amapayipi Awo Okukhipha Igesi phezulu?

Kungenzeka ukuthi uke wabona umMelikaamalolinalezo zitaki zikagesi ezimile eziphakeme futhi becabanga ukuthi zibukeka zinamandla—mhlawumbe “zithuthuke kakhulu” nakakhulu. Kulula ukucabanga ukuthi amapayipi wokukhipha abheke phezulu kufanele abe umklamo ongcono.

Kodwa empeleni, amapayipi wokukhipha umoya abheke phansi ayindinganiso yomhlaba wonke, futhi umklamo obheke phezulu empeleni uyivelakancane futhi awusebenzi kakhulu.

Bheka emhlabeni wonke—iYurophu, iJapane, iChina, nezinye izifunda eziningi zonke zisebenzisa amasistimu wokukhipha umoya okwehlayo. I-U.S. igqamile, futhi isizathu sihlobene nakho konke ukwakheka kwamaloli, hhayi ubuchwepheshe.

Kungani Amanye Amaloli Ephela Ephezulu kuyilapho Amanye Ephelela Phansi

Emigwaqweni yaseMelika, iloli lakudala liwuhlobo lwekhala elide (oluvamile). Kubukeka kukuhle, kepha kunesihibe esikhulu:

Ukusebenza kahle kwesikhala.

I-chassis yeloli idinga ukuthwala okuningiimishini emikhulu:

l amathangi amakhulu kaphethiloli

l amachibi omoya

l amabhokisi ebhethri

l ama-mufflers

l kanye nezinto ezifana namathangi egesi yemvelo noma amasistimu wokufafaza amanzi

Ikhebhu enekhala elide isivele ithatha ingxenye enkulu yesikhala sozimele. Lokho kushiya isikhala esincane salezi zingxenye.

I-exhaust system idinga kakhulu: ukugcina umsindo nezinga lokushisa phansi, idinga ipayipi elide kanye ne-muffler enkulu. Njengoba indawo elinganiselwe ngaphansi kweloli, onjiniyela akukho okunye abangakwenza ngaphandle kokukhuphula i-exhaust system phezulu, ngemuva kwekhebhu. Umsi umane uphumela esibhakabhakeni.Lokhu kukhawulelwa kwendawo yisona sizathu sangempela sokuthi amaloli aseMelika avamise ukuba nezitaki zokukhipha umoya ezikhuphukayo.

Ukukhathala Okuphezulu “Akuthuthuki”—Kuyi-Compromise

Idizayini ebheke phezulu ibukeka inamandla, kepha inobubi obuthile:

l I-exhaust ne-muffler kuhlala eduze nekhebhu, ngakho umsindo, ukushisa, nokudlidliza kufinyelela kumshayeli kalula.

l Ipayipi elikhipha umoya liya phezulu lilimaza i-aerodynamics futhi kwenyusa ukuhudula.

l Umsizi ungangcolisa impahla engemuva kwetekisi.

l Amanzi emvula angangena epayipini.

l I-soot nezinhlayiya aziwi kalula, okwenza ukuvala kube lula.

Kungani Amazwe amaningi Engasebenzisi Ama-Exhausts Aphezulu

Izifunda eziningi zisebenzisa amaloli e-cab-over, lapho i-cab ihlala khona ngqo phezu kwenjini. Lesi sakhiwo sisebenzisa isikhala kahle kakhulu. Indawo engemuva kwekhebhu ivulekile futhi ivulekile, okwenza kube lula ukufaka imishini ngaphansi kweloli.

Lokhu kwenza indlela ephumayo ebheke phansi ibe yinketho yemvelo.

Izinzuzo zihlanganisa:

l indlela emfushane yokukhipha umoya, ukuvinjelwa okuncane

l lula ukukhipha izinhlayiya

l ukugcinwa okulula

l akukho ukungcoliswa kwempahla

l Umsindo nokushisa kuqhelelene nomshayeliNgaphandle kokukhahlela uthuli ngezikhathi ezithile, umoya ophumayo obheke phansi uphezulu cishe ngazo zonke izindlela.

Kungani i-US Ithanda Amaloli Anekhala Emide Kanti Abanye Bengawathandi

Akukhona mayelana nezintandokazi zobunjiniyela-kumayelana nemithetho kanye nezimo zomgwaqo.

E-U.S., imikhawulo yobude beloli isebenza kuphela ku-trailer, hhayi ugandaganda.

Ngakho-ke itekisi ende ayiwehlisi nhlobo umthamo wezimpahla. Asikho isijeziso sokusebenzisa iloli elinekhala elide.

Kodwa e-China, eYurophu, eJapane, nakwezinye izindawo eziningi, yonke imoto ibalwa.

Ukusebenzisa umklamo wekhala elide kungafinyeza ibhokisi lempahla, ukusika ukusebenza kahle-ngakho-ke akuthandeki ngokwemvelo.

Izimo zomgwaqo nazo zibalulekile:

l I-U.S. inothelawayeka obanzi, ovulekile lapho izimoto ezinde kulula ukushayela khona.

l Amanye amazwe amaningi anemigwaqo emincane namakhona aminyene, okwenza amaloli amafushane abe yisidingo.

Ngakho-ke umehluko ufika emithethweni kanye nezwe, hhayi ubuchwepheshe.

I-Long-Nose vs. Cab-Over: Ngayinye Inezinzuzo zayo kanye ne-ConsLong-nose amaloli

Okuhle:

I-aerodynamics engcono emigwaqweni emikhulu

l ukuphepha kokuphahlazeka okuphezulu

ngikhululekile ukushayela amabanga amade

Ububi:

l ukusebenza kahle kwesikhala

Angilungile ekushintsheni okuqinile

l indawo elinganiselwe yezingxenye ezifana nesistimu yokukhipha umoya

Amaloli e-Cab-over

Okuhle:

l ukusetshenziswa kahle kwendawo

l iyalawuleka kakhulu

l i-chassis eguquguqukayo (kulula ukuyiguqula ibe amaloli okulahla, ama-flatbed, njll.)

Ububi:

Ngiphephile ngokwesiko kancane—yize imiklamo yesimanje isithuthuke kakhulu

Emashumini ambalwa eminyaka adlule, inkambiso yomhlaba wonke iye yathuthela kumiklamo eyonga isikhala. Ngisho nase-U.S., amaloli adlula ama-cab-over aqala ukuvama futhi, futhi lapho evela, amasistimu awo e-exhaust akhomba phansi njengayo yonke indawo.
