Injini yeHonda J32A
Okuqukethwe
Ngo-1998, onjiniyela abavela e-American Division of Honda bakha injini entsha kaphethiloli engu-3.2-litre, ebhalwe ukuthi J32A. Lapho uyidala, iyunithi yamandla ye-J30 V6 ene-block block ye-235 mm ithathwe njengesisekelo, lapho ububanzi besilinda buye banda ku-89 mm. Ubukhulu bezintambo zokuxhuma buhlala bufana (162 mm), kanye nokuphakama kokucindezelwa kwama-pistons (30 mm). Ngokushintsha usayizi amasilinda, Mechanics wakwazi ukunciphisa isisindo injini futhi uthole ukwanda 200 cm3 ivolumu.
Ulayini wenjini engu-6-cylinder V emise okwe-BC i-J32A (enamavalvu amane isilinda ngasinye) ibonakala ngokuba khona kwamakhanda amabili e-SOHC, ane-camshaft eyodwa kwelinye. Njengokwandulelayo, uchungechunge lwe-J32A lwamayunithi lufakwe uhlelo lwe-VTEC, kodwa ububanzi be-valve banda (kufika ku-34 no-30 mm, ukungenisa nokukhipha, ngokulandelana). Baphinde basebenzise izigaba ezimbili zokungenisa kanye ne-exhaust manifolds ebuyekeziwe.
Ukulungiswa kwe-J32A kwafakwa ku-Honda kuze kube ngu-2008, okwathi ngemva kwalokho kwashintshwa iyunithi ye-J35 enevolumu engu-3.5 amalitha.
Ukushintsha kwe-J32A
Ngemva kokulungiswa okumbalwa kwesitsha sokuqala sikagesi se-J32A, esinamandla okuqala aphezulu afinyelela ku-225 hp, onjiniyela bakwazi ukukhama okungaba ngu-270 hp enjinini.
Imodeli eyisisekelo yenjini ye-J32A, eqokwe i-A1, enamandla afinyelela ku-225 hp. futhi i-VTEC, esebenza ku-3500 rpm, ifakwe ku-Inspire, Acura TL kanye ne-Acura CL.
I-J32A2, efinyelela ku-260 hp, ukukhishwa kwekhanda lesilinda elithuthukisiwe kanye namakhamera anolaka, i-sport exhaust kanye ne-VTEC esebenza ngo-4800 rpm, ifakwe ku-Acura CL Type S kanye ne-TL Type S.
I-analogue ye-J32A2, iyunithi engaphansi kophawu A3, enamandla angu-270 hp, ebamba ukushisa okubandayo kanye nesistimu yokukhipha umoya, kanye ne-VTEC esebenza ngo-4700 rpm, itholakala ku-Acura TL 3.
Izinombolo zenjini zitholakala kumabhulokhi wesilinda kwesokudla, ngaphansi kwentamo yokugcwalisa uwoyela.
Izici eziyinhloko zokuguqulwa kwe-J32A:

Izinzuzo nezinkinga ze-J32A1/2/3
Ngobuchwepheshe, i-J32A iyi-analogue ephelele ye-J30A, ngakho izinzuzo nezinkinga zabo nazo ziyefana.
Плюсы
- I-BC emise okwe-V;
- Amakhanda amabili e-SOHC;
- I-VTEC.
Минусы
- amajika antantayo.
Izinjini eziningi ze-J32 namuhla sezindala futhi sezihambe amakhulu ezinkulungwane zamakhilomitha, ngakho-ke zingase zibe nezinye izinkinga.
Imbangela ye-rpm entantayo ngokuvamile i-valve ye-EGR engcolile noma umzimba we-throttle odinga ukuhlanzwa. Uma kungenjalo, ukugcinwa okufika ngesikhathi kwenjini, ukugcwalisa ngephethiloli ephezulu namafutha afanelekile, kanye nezinjini zochungechunge lwe-J32 ngeke kubangele noma iyiphi inkinga.
Ukushuna i-J32A
Cishe zonke izinjini ezishibhile ngokwemvelo zomndeni wakwa-"J" ziphakathi kwezinketho ezingcono kakhulu zokushintshwa noma ukushuna.
Ngokusekelwe ku-J32A, ungakwazi ukuhlanganisa iyunithi enhle kakhulu ngokuthatha, isibonelo, ukudla okuvela ku-J37A nokufaka i-damper ekhulisiwe kuyo. Yiqiniso, ukuthuthwa okuphelele kwekhanda le-cylinder kuzothuthukisa kakhulu ukusebenza kwamandla, kodwa mhlawumbe kwabanye kuzoba lula ukufaka amakhanda e-shaft eyodwa kusuka ku-J35A3 nama-camshafts avela ku-J32A2; ngaphezu kwalokho, abhekwa njengenye yezindlela ezinhle kakhulu zokulungisa i-J. - izinjini. Ngaphezu kwalokho, uzodinga iziphethu ezilungisiwe, ama-valve namapuleti (isibonelo, kusuka ku-Kovalchuk Motor Sport), kanye nokugeleza okuya phambili kwipayipi engu-63 mm. Konke lokhu kuzonikeza "amahhashi" angaphezu kuka-300 ku-flywheel.
Kungenzeka ukufeza ukusebenza okungcono nakakhulu usebenzisa i-crankshaft kanye nezinduku zokuxhuma ezivela ku-J37A1, kanye namapiston enjini ye-J35A8.
Kukhona inketho yokugcwalisa injini yefekthri futhi, ngokulungiswa okufanele, uthole ngaphezu kwe-400 hp, kodwa-ke kufanele usebenzise ukuqamba.
I-Turbocharged J32 Uhlobo S
Iphrojekthi yokushaja iyunithi ye-V6 yomugqa we-J32 ihilela imithwalo yesikhathi eside ngesivinini esikhulu, ngakho-ke kungcono ukuthatha i-J32A2 ku-Type-S njengesisekelo. Amandla agcinwe kule injini ikuvumela ukuba uzame futhi ukhulise kakhulu izici zobuchwepheshe.
Ibhulokhi kumele ifakwe ulayini, ifongwe ngezansi, amabhawodi kanye nezigxivizo zekhanda le-cylinder kanye ne-crankshaft zivela ku-ARP, isilawuli sikaphethiloli singesepompo elihle likaphethiloli, induku yokuxhuma nama-bearings ayinhloko ashuniwe, kanye nendawo yokubeka uphethiloli ene. ama-injection.
Kuyafaneleka ukucabangela ukuthi ithegi yentengo yama-piston kanye nezinduku zokuxhuma ze-compression ratio ye-~9 izoba ngu-50% ngaphezu kwenjini engu-4-boiler.
Ngemuva kokuthwala amakhanda, i-multiple ubude obulinganayo, i-FullRace exhaust, i-intercooler, ama-wastegates ashisa kakhulu, ama-blowoff, amapayipi, ama-turbines amabili (isibonelo, i-Garrett GTX28), izinzwa ze-EGT K-Type, ne-Hondata Flashpro zifakiwe ku- ECU.
isiphetho
Uchungechunge lwe-J32 lwaluhloselwe kuphela izimoto ezibiza kakhulu ze-Honda, noma izinguqulo eziphezulu zamamodeli athandwa kakhulu okuhloswe ngawo emakethe yase-US (phela, abantu baseMelika bathanda izinjini ezinjalo ngaphezu kwabanye). Kodwa-ke, ngokuhamba kwesikhathi, izinjini zomndeni "J" ezinevolumu yamalitha angu-3.2 ziye zazibonakalisa kahle emhlabeni wonke futhi isidingo sazo sisaqhubeka kuze kube yilolu suku, futhi lokhu akusona isizathu.
Kusukela ngo-1998 kuya ku-2003, akukho izinguquko ezibalulekile ezenziwe ekucushweni kwezinjini ezivuthayo zangaphakathi zomugqa we-J32, osebenza njengokuqinisekisa okungcono kakhulu kokuthembeka kokuphila kwabo isikhathi eside.
