Ibanga Lokuhlola IDrayivu Ye-Audi - Ingxenye 3: 2.0 TFSI, 2.5 TFSI, 3.0 TFSI

Ukuqhubeka kochungechunge lwamayunithi wokushayela we-brand

Namuhla, abaklami bezinjini zesimanje zikaphethiloli bafuna izindlela eziningi ezihlukahlukene zokwandisa ukusebenza kahle kwazo. Kuyiqiniso ukuthi udizili eminyakeni yakamuva nawo ahlangabezane nokwehliswa kwezinga lokwehla kwezinga lokufuduka, ukwanda komfutho womfutho kanye nesistimu yomjovo, futhi ngezinye izikhathi nokusetshenziswa kwesistimu yokushaja i-cascade turbocharging. Kodwa-ke, sekuyisikhathi eside besebenzisa ukugcwaliswa okuphoqelekile futhi, ngokungafani nabalingani babo bakaphethiloli, sebevele beqa isigaba sokuziphendukela kwemvelo sokusuka emkhathini kuya ekugcwalisweni okuphoqelelwe. Isimiso sokusebenza kwe-diesel ngokucindezela okukhulu kumasilinda kanye nokungabikho kwe-valve ye-throttle kwenza ukuthi baqale baphumelele. Ngakho-ke, ukwehla kwezinjini zikaphethiloli kuthatha uhlamvu oludlulele kakhulu ngokuncipha kwevolumu nenani lamasilinda kanye nokushintshela ekugcwalisweni ngempoqo. Kodwa-ke, izinga lokushisa eliphezulu lamagesi akhipha umoya uma kuqhathaniswa nodizili lisakwenza ukuthi ukusetshenziswa kwama-turbocharger aguquguqukayo ejometri (ngaphandle kwamayunithi e-BorgWarner ePorsche 911 Turbo), i-throttle valve iyaqhubeka nokwakha ukumelana komoya, futhi abaklami bafuna konke. ezinye izindlela ezingenzeka zokuthuthukisa ukusebenza kahle kwazo. Eminyakeni eyishumi edlule, i-Audi yethula okokuqala inhlanganisela ye-turbocharging kanye nomjovo kaphethiloli oqondile nge-TFSI yayo, futhi manje ngeyunithi yayo entsha ye-2.0 TFSI, onjiniyela benkampani babuyele kumjikelezo owaziwayo weMiller - kuphela ngendlela eguquliwe. Ukumaketha kwenkampani kubiza ifilosofi yokudala yemoto entsha enamandla angu-190 hp. kanye ne-torque engu-320 Nm "rightsizing", ngomqondo "wevolumu yokusebenza ekhethwe kahle". Nokho, leli gama lihluke kakhulu emyalezweni wozakwabo bakwaMazda, ababhekisela kulokhu ekugwemeni ukugcwaliswa ngenkani.

Ngokuphambene nalokho, kwa-Audi, ukwenza ama-turbocharging kuyisici esibalulekile kucebo lokuhamba kwenjini entsha, njengoba nje i-compressor iyimfanelo engenakulinganiswa yemishini yomjikelezo kaMiller, ejwayelekile kunazo zonke iMazda Millenia yama-90s. Lo mgomo wokusebenza uhilela ukugcina i-valve yokudla ivulekile isikhathi eside ngemuva kokuthi i-piston isiqalile ukusuka phansi iye esikhungweni esiphezulu esifile. Njengoba umoya uqala ukubuyela ezinhlakeni eziningi zokungenisa, i-compressor yemishini, edala ingcindezi yangemuva, inakekela ukugcinwa kwayo. Ekuboneni kokuqala, lokhu kubonakala kungenangqondo, kepha empeleni amandla okugeleza okuthi kuleli cala athole ukumelana okuncane kunokucindezelwa kusilinda uqobo. Ngakolunye uhlangothi, izinga lokushaywa unhlangothi likhuphuka ngezinga elijwayelekile lokucindezelwa ngaphandle kwengozi yokuqhuma. Lokho wukuthi, umgomo kaMiller uvumela ukuthi kufinyelelwe ezingeni elihlukile lokucindezelwa nokukhuliswa, kunokufana nenjini ejwayelekile ye-Otto. Umphumela omuhle futhi uyikhono lokusebenza nge-valve mpintsha evulekile evulekile.

Ukuchazwa kuka-Audi ngomjikelezo kaMiller

Abaklami be-Audi bahumusha le timu ngendlela yabo. Ngokungafani nenqubo eyisisekelo, nokho, esikhundleni sokubamba i-valve yokungena ivuleke ukuze kuncishiswe isilinganiso sokucindezela, bavele bayivale kusenesikhathi - ngaphambi kokuba i-piston ifinyelele ngisho nendawo efile. Esikhundleni sokuthi isikhathi sokuvula sibe amadigri angu-190-200 wokujikeleza kwe-crankshaft njengenjwayelo, i-valve ihlala ivulekile kuphela ama-degree angu-140. Kodwa-ke, ekusebenzeni, lokhu kufeza umphumela ofanayo wokunciphisa isilinganiso sokucindezela. Ukunxephezela isikhathi esincishisiwe sokuvula kwenziwa ngokwandisa umfutho we-boost usebenzisa i-turbocharger. Ngakho-ke, injini ifinyelela ukusetshenziswa kwenjini yokunciphisa, futhi uma ilayisha ngokugcwele inokusebenza okunamandla komshini omkhulu. Emsebenzini wokulayisha ingxenye, umjovo owengeziwe kaphethiloli wenziwa ekushayeni phezulu kwepiston kusetshenziswa uhlelo lomjovo oqondile, oluhambisana nolunye uhlelo lomjovo kuma-manifolds wokudla. Ukwengeza, i-Audi Valvelift System (AVS) yesikhathi se-valve eguquguqukayo ivumela isigaba sokuvula sama-valve wokungenisa ukuba senyuke sibe ngama-degree angu-170 ngaphansi komthwalo ogcwele. Ukwengezwa kulokhu ukuphathwa kokupholisa okuhlakaniphile, i-exhaust eningi ehlanganiswe nekhanda kanye nokunciphisa ukungqubuzana okuqhubekayo ngokusebenzisa uwoyela we-viscosity ephansi (0W-20). Ngenxa yezixazululo eziningi zobuchwepheshe obuphezulu, i-2.0 TFSI entsha ine-torque ephezulu ebangeni lika-1450 kuya ku-4400 rpm futhi idla uphethiloli omncane.

3.0 TFSI: Mechanical esikhundleni se-turbocharger

Ozakwethu basePorsche bakhetha ukugcwaliswa kwebiturbo ngenjini yabo engu-litre amathathu i-V6 ene-420 hp. Kwi-3.0 TFSI, i-Audi isebenzisa umshini wokuqhafaza ngomshini (isizukulwane sesithupha se-Eaton, u-R1320) esifakwa phakathi kwamanzi / nomoya. Inqubo yokudala injini ibimfishane ngokwedlulele, okungenzeka ukuthi ingesinye sezincazelo zalesi sinqumo, yize abakwa-Audi bethi lo mqondo uyathandwa ngenxa yezinye izinzuzo - njengokuthandwa kwalolu hlobo lokugcwaliswa ngenkani e-United States. Imininingwane yesixazululo se-Audi ifaka i-compressor etholakala ngemuva kwe-valve mpintsha, ekhulisa kakhulu ukusebenza kahle kokugcwalisa. Kumthwalo omncane, i-valve ekhethekile esezindlini ze-compressor ibuyisela omunye umoya ocindezelwe ekungeneni kwayo, ngaleyo ndlela kunciphise ukulahleka namandla adingekayo ukuwuzungezisa. Ngokwenza, kuze kube kumamodi athile, iyunithi isebenza cishe njengemoto yasemkhathini futhi umthwalo omkhulu kuphela lapho i-compressor iqala ukusebenza ngokugcwele.

2.5 TFSI: Amasilinda ayisihlanu wezinguqulo zemidlalo ezihlangene

Lolu phiko lulandela izinkulumo eziningi zezinye izinjini zale nkampani, kubhekwa imininingwane yezinjini ezinamasilinda amahlanu. I-2.5 TFSI, nokho, inomkhakha olinganiselwe wokusebenzisa futhi inika amandla amamodeli kuphela njenge-Audi RS 3, TT RS kanye ne-RS Q3. Enguqulweni ye-Audi TT RS plus, injini ene-displacement engu-2,48 amalitha inamandla angu-360 hp. – efanayo nenjini entsha ye-AMG enamasilinda amane ye-A-Class kanye nokuphuma kwayo. Nokho, injini ezinhlanu-cylinder inikeza torque yayo esiphezulu 465 Nm ngaphambili kakhulu (in uhla 1650 kuya 5400 rpm) kuka umshini ozakwabo Stuttgart.
