Kutheni iilori zaseKhaya zingajongi iMibhobho yazo yokukhupha phezulu?

Usenokuba wabona umMelikaiiloringezo mfumba ziphakamileyo ezithe nkqo kwaye bacinga ukuba zibonakala zinamandla—mhlawumbi “zihambele phambili” ngakumbi. Kulula ukucinga ukuba imibhobho yokukhupha ejonge phezulu kufuneka ibe luyilo olungcono.

Kodwa eneneni, imibhobho yokukhupha ejonge ezantsi ngumgangatho wehlabathi, kwaye uyilo oluya phezulu lunqabile kwaye alusebenzi kakhulu.

Jonga kwihlabathi jikelele-iYurophu, iJapan, iChina, kunye neminye imimandla yonke isebenzisa inkqubo yokuphuma ezantsi. I-US ivelele, kwaye isizathu sinayo yonke into yokwenza nesakhiwo selori, kungekhona iteknoloji.

Kutheni ezinye iilori zidinwe phezulu ngelixa ezinye zidiniwe zijonge ezantsi

Kwiindlela zaseMelika, ilori yakudala luhlobo lwempumlo ende (yesiqhelo). Ikhangeleka intle, kodwa ine-drawback enkulu:

Ukusebenza kakuhle kwendawo.

I-chassis yelori ifuna ukuthwala okuninziizixhobo ezikhulu:

l iitanki ezinkulu zamafutha

l iimithombo zomoya

l iibhokisi zebhetri

l iimufflers

l kunye nezinto ezifana neetanki zegesi yendalo okanye iinkqubo zokutshiza ngamanzi

Ikhabhathi enempumlo ende sele ithatha indawo enkulu yefreyimu. Oko kushiya indawo encinci kula malungu.

Inkqubo yokukhupha ifuna ngokukodwa: ukugcina ingxolo kunye nobushushu phantsi, idinga umbhobho omde kunye ne-muffler enkulu. Ngesithuba esilinganiselweyo phantsi kwelori, iinjineli azinakwenza nto ngaphandle kokunyusa inkqubo yokukhupha umoya ukuya phezulu, emva kwekhebhu. Umbhobho uphuma usiya esibhakabhakeni. Lo mda wesithuba sesona sizathu sokwenyani iilori zaseMelika zihlala zinemfumba ephuma phezulu.

Ukudinwa Okuya Phezulu “Akuko “Advanced”—Yinto yokuHluba

Uyilo oluphezulu lukhangeleka lunamandla, kodwa lunamazantsi amaninzi:

l I-exhaust kunye ne-muffler ihlala kufuphi ne-cab, ngoko ingxolo, ubushushu, kunye nokungcangcazela kufikelela kumqhubi ngokulula.

l Umbhobho ovuthela phezulu uyonakalisa i-aerodynamics kwaye kwandisa ukutsalwa.

l Uthuthu luyakwazi ukungcolisa imithwalo emva kwekhebhu.

l Amanzi emvula angangena kumbhobho.

l I-Soot kunye ne-particulates ayiphumeleli ngokulula, okwenza ukuvala ukuvala kunokwenzeka ngakumbi.Ngamafutshane, i-point-upward design ayikhethwanga ukusebenza-ikhethwe ngenxa yokuba akukho ndawo yokuyibeka.

Kutheni uninzi lwamazwe lungasebenzisi iExhausts ephezulu

Uninzi lweengingqi zisebenzisa iilori ze-cab-over, apho i-cab ihlala ngokuthe ngqo phezu kwe-injini. Olu yilo lusebenzisa indawo ngokufanelekileyo kakhulu. Indawo esemva kwekhabhi ivulekile kwaye ivulekile, okwenza kube lula ukufaka izixhobo phantsi kwelori.

Oku kwenza umbhobho ojonge ezantsi ube yinketho yendalo.

Izibonelelo ziquka:

l indlela emfutshane yokukhupha, uthintelo oluncinci

l lula ukukhutshwa kwe-particulate

l ulondolozo olulula

l akukho kungcoliseka kwempahla

l ingxolo kunye nobushushu obugcinwe kude nomqhubiNgaphandle kokukhaba uthuli ngamaxesha athile, umsi ongezantsi uphezulu phantse ngandlela zonke.

Kutheni i-US ithanda iilori ze-Long-Nose kunye nabanye abayithandi

Akunjalo malunga nokukhethwa kobunjineli-kumalunga nemimiselo kunye neemeko zendlela.

E-U.S., imida yobude belori isebenza kuphela kwinqwelwana, hayi itrektara.

Ke i-cab ende ayinciphisi umthamo wempahla kwaphela. Akukho sohlwayo sokusebenzisa ilori enempumlo ende.

Kodwa eTshayina, eYurophu, eJapan nakweminye imimandla emininzi, isithuthi siphela sibalwa.

Ukusebenzisa i-design yempumlo ende kuya kunciphisa ibhokisi yempahla, ukusika ukusebenza kakuhle-ngoko akuthandeki ngokwemvelo.

Iimeko zendlela nazo zibalulekile:

l I-US ineendlela ezibanzi, ezivulekileyo apho izithuthi ezide kulula ukuziqhuba.

l Amanye amazwe amaninzi anezitalato ezimxinwa kunye neekona ezixineneyo, nto leyo eyenza ukuba iilori ezimfutshane zibe yimfuneko.

Ngoko ke umahluko ufika kwimithetho kunye nejografi, kungekhona iteknoloji.

I-Long-Nose vs. Cab-Over: Nganye IneeNgxaki zayo kunye neConsLong-nose iilori

IiPros:

I-aerodynamics engcono koohola bendlela

l ukhuseleko oluphezulu lwengozi

Ndikhululekile ukuqhuba umgama omde

Ububi:

l ukusebenza kakuhle kwendawo

Andilunganga kwiinguqu eziqinileyo

l igumbi elilinganiselweyo lamacandelo afana neenkqubo zokukhupha

Iilori zeCab-over

IiPros:

l usetyenziso oluhle kakhulu lwendawo

Ndiyalawuleka kakhulu

I-chassis eguquguqukayo (elula ukuyiguqulela kwiilori zokulahla, ii-flatbeds, njl.)

Ububi:

Ngokwesiko andikhuselekanga kancinci-nangona uyilo lwangoku luphucuke kakhulu

Kwiminyaka embalwa edlulileyo, imeko yehlabathi iye yafudukela kuyilo olusebenzayo kwindawo. NaseU.S., iilori ezingaphaya kwee-cab-over ziya zixhaphaka kwakhona, kwaye xa zivela, iinkqubo zazo zokuphuma zikhomba ezantsi njengayo yonke enye indawo.
