Honda J32A injini
Zamkatimu
Mu 1998, injiniya ku division American Honda anapanga latsopano 3.2-lita mafuta injini otchedwa J32A. Pamene analengedwa, J30 V6 mphamvu unit ndi chipika kutalika 235 mm anatengedwa monga maziko, imene yamphamvu m'mimba mwake chinawonjezeka 89 mm. Miyeso ya ndodo zolumikizira zidasiyidwa chimodzimodzi (162 mm), monganso kutalika kwa ma pistoni (30 mm). Ndi kusintha kukula kwa masilindala, minders anatha kuchepetsa kulemera kwa injini ndi kuwonjezeka 200 cm3 voliyumu.
Ma injini a J6A 32-cylinder V amtundu wa V a injini ya J32A (yokhala ndi ma valve anayi pa silinda) amadziwika ndi kukhalapo kwa mitu iwiri ya SOHC, yokhala ndi camshaft imodzi iliyonse. Monga momwe zimakhalira, mayunitsi a J34A anali ndi dongosolo la VTEC, koma kukula kwa ma valve kunawonjezeka (mpaka 30 ndi XNUMX mm, kudya ndi kutulutsa, motero). Amagwiritsidwanso ntchito potengera magawo awiri ndikuwonjezera kutulutsa kowonjezera.
Zosintha za J32A zidayikidwa pagalimoto ya Honda mpaka 2008, kenako zidasinthidwa ndi unit J35 ndi buku la malita 3.5.
Zithunzi za J32A
Pambuyo pakusintha kangapo pagawo loyamba lamagetsi la J32A, lokhala ndi mphamvu zoyambira mpaka 225 hp, mainjiniya adatha "kufinya" mpaka 270 hp kuchokera mu injini.
Chitsanzo choyambira cha injini ya J32A pansi pa index A1, ndi mphamvu mpaka 225 hp. ndi VTEC, yomwe imagwira ntchito pa 3500 rpm, inayikidwa pa Inspire, Acura TL ndi Acura CL.
J32A2 yokhala ndi 260 hp, kuwongolera mitu ya silinda ndi ma camshaft ankhanza kwambiri, utsi wamasewera ndi 4800 rpm VTEC idalumikizidwa ku Acura CL Type S ndi TL Type S.
Analogue ya J32A2, unit yomwe ili pansi pa index A3, yokhala ndi mphamvu ya 270 hp, yokhala ndi kuzizira kozizira komanso makina opopera osinthidwa, komanso VTEC ikugwira ntchito pa 4700 rpm, imapezeka pa Acura TL 3.
Nambala za injini zili pazitsulo za silinda kumanja, pansi pa khosi lodzaza mafuta.

Ubwino ndi mavuto a J32A1/2/3
Pa mbali luso, J32A ndi analogue wathunthu J30A, kotero ubwino ndi mavuto ndi ofanana.
Плюсы
- BC wooneka ngati V;
- Mitu iwiri ya SOHC;
- Chithunzi cha VTEC.
Минусы
- Zosintha zoyandama.
Ma injini ambiri a J32 masiku ano ali kale ndi zaka zabwino ndipo amatha kuyenda makilomita mazana masauzande, kotero akhoza kusonyeza mavuto ena.
Chifukwa cha rpm yoyandama nthawi zambiri imakhala valavu ya EGR yakuda kapena thupi lopumira lomwe limayenera kutsukidwa. Apo ayi, kukonza injini yake mwachizolowezi, refueling ndi mafuta apamwamba ndi mafuta abwino, ndi injini J32 mndandanda sangabweretse vuto lililonse.
Kusintha kwa J32A
Pafupifupi mainjini onse omwe amafunidwa mwachilengedwe a banja la "J" ndi amodzi mwa njira zabwino kwambiri zosinthira kapena kusintha.
Kutengera J32A, mutha kusonkhanitsa gawo labwino kwambiri potenga, mwachitsanzo, cholowera kuchokera ku J37A ndikuyika chowonjezera chowonjezerapo. Zachidziwikire, kuyika bwino kwa mutu wa silinda kumathandizira kwambiri mphamvu zamagetsi, koma zitha kukhala zosavuta kuti wina aike mitu ya shaft imodzi kuchokera ku J35A3, ndi ma camshafts ochokera ku J32A2, kuphatikiza apo, amatengedwa kuti ndi imodzi mwazabwino kwambiri pakuwongolera J. -injini. Komanso, muyenera anachunidwa akasupe, mavavu ndi mbale (mwachitsanzo, Kovalchuk Motor Sport), komanso otaya patsogolo pa chitoliro 63 mm. Zonsezi zidzapereka "akavalo" oposa 300 pa flywheel.
Kuchita bwino kwambiri kungapezeke ndi crankshaft ndi ndodo zolumikizira kuchokera ku J37A1, komanso ma pistoni a injini ya J35A8.
Pali mwayi woti mufufuze mu injini ya fakitale ndipo, ndi makonzedwe oyenera, pezani ma hp opitilira 400, koma ndikofunikira kugwiritsa ntchito kupanga.
Turbocharged J32 Mtundu S
Pulojekiti yopangira turbocharge unit ya V6 ya mzere wa J32 ikutanthauza njira yolemetsa yanthawi yayitali pa liwiro lalikulu, kotero ndikwabwino kutenga J32A2 kuchokera ku Type-S ngati maziko. Mphamvu yosungirako injini iyi imakupatsani mwayi woyesera ndikuwonjezera mawonekedwe aukadaulo nthawi zina.
Chidacho chiyenera kukhala chokhala ndi manja, chopukutira pang'ono, ma bolts ndi zipilala za silinda mutu ndi crankshaft zimachokera ku ARP, chowongolera mafuta ndi pampu yabwino yamafuta, ndodo yolumikizira ndi mayendedwe akuluakulu amakonzedwa, komanso njanji yamafuta yokhala ndi majekeseni. .
Ndikoyenera kulingalira kuti mtengo wa pistoni ndi ndodo zolumikizira za chiŵerengero cha psinjika ~ 9 zidzakhala 50% kuposa injini ya 4-boiler.
Pambuyo ponyamula mitu, kutalika kofanana, kutulutsa kwa FullRace, intercooler, zinyalala zotentha kwambiri, zophulika, mapaipi, ma turbines (mwachitsanzo, Garrett GTX28), masensa a EGT K-Type, ndi Hondata Flashpro ku ECU. amaikidwa.
Pomaliza
Mndandanda wa J32 unapangidwira magalimoto okwera mtengo kwambiri a Honda, kapena mitundu yapamwamba kwambiri yamitundu yotchuka kwambiri yomwe ikupita ku msika waku US (pambuyo pake, aku America amakonda injini zotere kuposa wina aliyense). Komabe, m'kupita kwa nthawi, injini za banja "J" ndi voliyumu ya malita 3.2 adzitsimikizira okha padziko lonse ndi kufunika kwa iwo akupitiriza mpaka lero, ndipo palibe chifukwa.
Kuchokera mu 1998 mpaka 2003, palibe kusintha kwakukulu kwa kasinthidwe ka mzere wa J32 wa injini zoyaka mkati, zomwe zimatsimikizira kudalirika kwa nthawi yawo yogwira ntchito.
