Iyini i-bi-turbo noma i-parallel boost? [ukuphatha]

Abaklami bezinjini ze-V bangaba nenkinga enkulu yokubacindezela nge-turbocharger eyodwa. Yingakho i-parallel boost system ivame ukusetshenziswa, i.e. i-bi-turbo. Ngiyachaza ukuthi kuyini.

I-turbocharger ngayinye ine-inertia ngenxa yobuningi be-rotor, okumele isheshiswe ngamagesi okukhipha umoya. Ngaphambi kokuthi amagesi e-exhaust afinyelele isivinini esanele ukuvuselela injini, kwenzeka lokho okwaziwa ngokuthi i-turbo lag. Ngabhala okwengeziwe ngalesi senzakalo embhalweni mayelana nejometri eguquguqukayo ye-turbocharger. Ukuze siqonde lesi sihloko esingezansi, kwanele ukwazi ukuthi amandla amaningi esiwafunayo noma ubukhulu benjini enkulu, i-turbocharger enkulu esiyidingayo, kodwa inkulu, kuba nzima kakhulu ukuyilawula, okusho ukubambezeleka okwengeziwe. ukuphendula igesi.

Ezimbili esikhundleni sokukodwa, i.e. i-bi-turbo

KwabaseMelika, inkinga ye-supercharging V-injini yaxazululwa kudala, ngoba basebenzisa isisombululo esilula kunazo zonke, i.e. i-compressor eshayelwa ngokuqondile ku-crankshaft. Idivayisi enkulu yamandla aphezulu ayinazo izinkinga ze-turbo lag ngoba ayiqhutshwa amagesi e-exhaust. Enye into ukuthi, naphezu supercharging enjalo, injini namanje izici omunye emkhathini, ngoba ijubane compressor landa ngendlela efanayo ijubane injini. Kodwa-ke, amayunithi aseMelika awanazo izinkinga ngamaqoqo ngesivinini esiphansi ngenxa yamandla amakhulu.

Isimo sasihluke ngokuphelele eYurophu noma eJapane, lapho amayunithi amancane abusa phezulu, ngisho noma kuyi-V6 noma i-V8. Basebenza ngokuphumelelayo nge-turbocharger, kodwa lapha inkinga itholakala ekusebenzeni kwamabhange amabili amasilinda ane-turbocharger eyodwa. Ukuze unikeze inani elifanele lomoya kanye nomfutho wokukhulisa, udinga nje ukuba mkhulu. Futhi njengoba sesivele sazi, enkulu isho inkinga nge-turbo lag.

Ngakho-ke, inkinga yaxazululwa ngesistimu ye-bi-turbo. Iqukethe icubungula amakhanda amabili enjini ye-V ngokuhlukana futhi ijwayelanisa i-turbocharger efanelekile ngayinye. Enjinini efana ne-V6, sikhuluma nge-turbocharger esekela amasilinda amathathu kuphela ngakho incane uma kuqhathaniswa. Umugqa wesibili wamasilinda unikezwa i-turbocharger yesibili, efanayo.

Ngakho-ke, ngokufingqiwe, uhlelo lomjovo oluhambisanayo alulutho ngaphandle kwama-turbocharger afanayo amabili asebenzisa umugqa owodwa wamasilinda ezinjini ezinamakhanda amabili (amise okwe-V noma aphikisiwe). Kuyenzeka ngokobuchwepheshe ukusebenzisa ukushaja okuhambisanayo kweyunithi yomugqa, kodwa ezimweni ezinjalo, isistimu yokushaja efanayo, i-twin-turbo, isebenza kangcono. Kodwa-ke, ezinye izinjini ze-BMW 6-cylinder zine-parallel supercharged, i-turbocharger ngayinye isebenzisa amasilinda amathathu.

Inkinga yesihloko

I-bi-turbo nomenclature isetshenziselwa ukushaja okufanayo, kodwa abakhiqizi bezimoto nezinjini abawulandeli lo mthetho ngaso sonke isikhathi. Igama elithi bi-turbo libuye lisetshenziswe kaningi esimweni sokulandelana kwe-topping up, okuthiwa. Izinhlelo ze-TV. Ngakho-ke, akunakwenzeka ukuthembela kumagama ezinkampani zezimoto ukuqaphela uhlobo lwe-supercharging. Okuwukuphela kwegama lamagama okungangabazeki ukuthi izengezo ezilandelanayo nezihambisanayo.
