Yini okudingeka uyazi mayelana nokusebenzisa uphethiloli?

Yini enquma ukusetshenziswa kukaphethiloli

Ziningi izinto ezithinta ukusetshenziswa kukaphethiloli. Okokuqala, yi-aerodynamics, amandla kanye nenjini okugxilwe kuma-revs aphansi. Kanye nokumelana komphezulu womgwaqo. Amandla amaningi asetshenziselwa ukusheshisa ngaphambi kokushintsha isivinini, kepha amandla asetshenziswa kuphela ekunqobeni ukumelana nalokho. Ngakho-ke, ukunciphisa ukukhishwa kwezinto ezinobungozi ezivela kumbhobho wokuqothula, abezemvelo batusa ukusebenzisa indlela elula yokusebenza nepheduli ye-accelerator. Ungayicindezela ekuqaleni kuphela, kepha ngemuva kwejubane lamakhilomitha angama-30 ngehora, kulula ukuthinta. Lapho-ke injini ngeke ijikeleze ngenhla kwama-2500 rpm. Futhi lokho kwanele empilweni yasedolobheni. Izinjini zesimanje zisebenza kahle. Ngenxa yomjovo oqondile, u-80% we-torque ngo-1200 rpm ungatholakala.

Ukusetshenziswa komoya

Uma injini ifakwe i-valve system eguquguqukayo, khona-ke u-80% we-thrust utholakala ngo-1000 rpm. Lokhu kusho ukuthi ayikho igesi edingekayo ekuqaleni okuthambile nokusheshisa. Ngendlela, ngokusho kwezinkambiso zomjikelezo waseYurophu Ephakathi, ukusheshisa kwamakhulu kwenziwa ngemizuzwana engama-30, futhi amandla afanayo afanayo kwenzeka ngaphakathi kwezinguquko ezingama-2000. Akulula ukugcina injini ingagijimi ngokweqile. Uma imoto ifakwe ukudluliswa okwenziwa ngesandla, khona-ke ungakhululeka ngokushelela i-pedal engenzi lutho, futhi injini uqobo, ifakwe umjovo we-elekthronikhi, inyusa kancane i-clutch ukuze ingami. Izinhlobo ezintsha zeBMW neMINI manje zinohlelo lokuqala olungashayeli. Uyihlola kanjani imoto ngaphambi kokushayela? Kodwa-ke udinga ukungena egiyeni eliphezulu ngokushesha okukhulu.

Iyiphi igiya imoto ethola ukusetshenziswa okuhle kukaphethiloli

Ngesivinini esingamakhilomitha angama-30 ngehora, kuyadingeka ukuvula igiya lesine, futhi ngesivinini esingamakhilomitha angama-60 ngehora - eyesithupha. Khona-ke injini izosebenza ngaphansi kuka-2000 rpm, ukusetshenziswa kukaphethiloli kuzokwehla kakhulu. Isibonelo, i-3000 rpm idla izikhathi ezingu-3,5 ezingaphezu kuka-1500 rpm. Ngakho-ke, ukushayela ngesivinini samakhilomitha angama-50-60 ngehora ngegiya eliphezulu kuzonciphisa ukusetshenziswa kwenjini engu-1,6 litre ibe amalitha angama-4-5. Le ndlela iyasiza lapho izinga likaphethiloli liyi-zero, lapho kudingekile ukubekezelela umzamo wokugcina esiteshini segesi esiseduze. Ngaphezu kwalokho, izimoto zesimanje zisebenzisa i-Start-Stop system evala injini ngokuzenzakalelayo ngesikhathi sokuma kwezimo eziphuthumayo.

Ukusetshenziswa kwephethiloli injini icishiwe

Ukuma esiminyaminyeni sezimoto naphambi kwamarobhothi ngaphandle kwamandla okusebenza kunikeza isamba esingu-5% ukonga uphethiloli. Kodwa lapha kufanele sikhumbule ukuthi ukuqala njalo kuyingozi kumakhenikha, futhi kungcono ukucisha injini ezitobhini ezihlala isikhathi eside kunomzuzu owodwa. Amathayi kanye ne-aerodynamics. Amathayi aphefumulelwe kahle asiza ukonga uphethiloli. Abakhiqizi abaningi batusa ukufaka umoya amathayi angaphambili abe yibha engu-2,2 kanye namathayi angemuva abe yibha engu-2,3 ngaphansi kwezimo ezijwayelekile. Lena yingcindezi enethezekile yamathayi angu-R16 no-R17. Kodwa abaningi abawaqapheli amathayi izinyanga, bavumele ukuthi banciphise ingcindezi futhi bakhohlwe ukuthi isondo liyacwila emotweni eshajiwe. I-patch yokuxhumana iyakhula, okuholela ekwenyukeni kokugqoka nokusetshenziswa kukaphethiloli. Ngakho-ke, ukuze uhambe nomndeni ezweni lonke ngezinto ezijwayelekile esiqwini, udinga ukwandisa umfutho wesondo.

Amathiphu Okwehla kwamandla emali eTire

Ngemodeli ngayinye yemoto nosayizi wesondo, inani laso linqunywa. Isibonelo, kwiFocus II enamasondo angama-205/55 R 17, kunconywa ukusebenzisa ibha engu-2,8 kumasondo angemuva. NakuFord Mondeo kunconywa ukuthi unyuse amasondo angemuva u-215/50 R 17 uye ku-2,9 bar. Futhi lokho kungu-10% womnotho kaphethiloli. Kepha ngaphambi kokuvula amasondo, udinga ukufunda imiyalo. Ingcindezi enconyiwe yomshini othize ingatholakala kuzinqumo ezithile. Lezi zivame ukutholakala kusikhwama sethangi likaphethiloli. Ukulandela izincomo zomkhiqizi kuzoba nomthelela omuhle ekusebenzeni kwamathayi. Ukudonswa, ukundiza olwandle, ukusebenza kahle kukaphethiloli kanye nemayili yesondo. Kepha okubaluleke kakhulu, ukuze kugwenywe ukwanda kokusetshenziswa kukaphethiloli, amandla okushayela umoya wemoto akufanele aphazanyiswe.
