Honda H22A injini
Mu 1991, Honda anapezerapo m'badwo wachinayi wa coupe ake okhala anayi Prelude, amene anali okonzeka ndi H22A ICE watsopano. Ku US, unit iyi idayamba mu 1993 ngati H22A1, pambuyo pake idakhala injini yosayina ya Prelude mpaka kumapeto kwa kupanga kwake mu 2000. Zosiyanasiyana zidayikidwa pa Accord SiR pamsika waku Japan ndi Accord Type R pamsika waku Europe.
Mu 1994, H22A, yochepetsedwa mpaka 2.0 malita, idagwiritsidwa ntchito ngati injini ya Formula 3. Kenaka, kuchokera ku 1997-2001, H22 inasinthidwa ndi Mugen Motorsports ndipo inadziwika kuti F20B (MF204B). Kuchokera ku 1995-1997, Honda Team MSD, yomwe inachita nawo mpikisano wa BTCC International Touring Car Championship, idakhala ndi malo amphamvu mu H22A-powered Accord. Komanso, mu 1996-1997 Honda ntchito wagawo yemweyo pa Mogwirizana mu mpikisano dziko mndandanda "JTCC" ndipo anapambana zaka ziwiri zotsatizana.
Mpaka 1997, onse H22A injini mafuta ndi kusamuka kwa malita 2.2 anali chatsekedwa zinayi yamphamvu zotayidwa chipika ndi kutalika kwa 219.5 mm, ndipo pambuyo, ndipo mpaka mapeto a kupanga anali otseguka. Mkati mwa chipika anaikidwa: crankshaft ndi pisitoni sitiroko (m'mimba mwake 87 ndi psinjika kutalika - 31 mm) - 90.7 mm; ndodo zolumikizira, 143 mm kutalika ndi mitsinje yokwanira.
Mutu wamapasa-shaft H22A wa silinda wokhala ndi ma valve 4 pa silinda amagwiritsa ntchito VTEC yonse, yogwira ntchito pa 5800 rpm. Kutalika kwa mavavu olowera ndi kutulutsa ndi 35 ndi 30 mm, motsatana. Pambuyo pa 1997, majekeseni a 345cc adasinthidwa ndi 290cc. Zosintha zonse za H22A (kupatula H22A Red pamwamba) zinali ndi chowongolera cha 60 mm.
Mofanana ndi magetsi a mzere wa H, injini zofananira za banja la F zidapangidwa. Komanso, pamaziko a H22A, 23-lita H2.3A ICE idapangidwa. Mu 2001, Honda anasiya ake mkulu-ntchito H22A injini, m'malo amene Mogwirizana anayamba kukhazikitsa K20 / 24A.
H22A voliyumu ya malita 2.2, ndi mphamvu mpaka 220 hp. (pa 7200 rpm) ndi makokedwe pazipita 221 Nm (pa 6700 rpm), anaika pa Mogwirizana, Prelude ndi Torneo.

Ubwino ndi zovuta za H22A
Kuti muchepetse mavuto ndi H22A, ndikofunikira kuyang'anira momwe zinthu ziliri ndikuzitumikira nthawi zonse, komanso kukumbukira kugwiritsa ntchito mafuta opangidwa ndi wopanga, apo ayi moyo wa injini ukhoza kuchepetsedwa kwambiri.
Плюсы
- Aluminiyamu ya XNUMX-cylinder BC yokhala ndi makoma a silinda okhala ndi FRM.
- Pangani khalidwe.
Минусы
- Kugwiritsa ntchito kwambiri komanso kutulutsa mafuta.
- Kutayikira mu makina ozizira chifukwa cha mipope kwakanthawi kochepa.
- Kuchedwetsedwa kukanikiza chonyamulira chothamangitsira.
"Maslozhor" ndizofala kwambiri pa injini zotere, ndipo poipa kwambiri, malaya a BC kapena kugula injini yatsopano yoyaka moto amafunika kuchotsa mafuta ambiri. Ponena za kutuluka kwa mafuta, tikhoza kunena kuti nthawi zambiri chifukwa chake chimakhala muzitsulo zamafuta ozizira kapena VTEC, komanso DDM kapena pulagi ya camshaft.
Ngati antifreeze ikuyenda, muyenera kuyang'ana valve ya EGR, mwinamwake vuto liri mmenemo ndipo KXX imangofunika kutsukidwa.
Kuchedwerapo kukanikiza chonyamulira chothamangitsira kungakhale chifukwa cha wogawa, masensa kutentha, mpweya, kapena kuphulika. Komanso, pangakhale kofunikira kusintha ma valve kapena lamba lamba.
Vavu kusintha ikuchitika pambuyo 40-50 zikwi Km. Mipata yozizira: kulowa - 0.15-0.19 mm; maphunziro - 0.17-0.21 mm.
Kukonzekera kwa injini ya Honda H22A
Ma cylinder anayi H22A okhala ndi 220 hp mukhoza "kumasula" kwambiri, ndipo ziribe kanthu kuti kusinthidwa kwa injiniyi kuti mutenge ngati maziko, chifukwa mumayenera kusintha ma shafts ndikusintha mutu wa silinda.
Kuti mutsitsimutse H22 yakale, mutha kukhazikitsa manifold a Euro R blackhead, kuzizira, 70mm throttle, 4-2-1 manifold ndi 63mm utsi. Mwinanso kukonzanso kwina (komwe kwafotokozedwa pansipa) sikuli koyenera, pokhapokha ngati pali chikhumbo chogwiritsa ntchito ndalama moyenera.
Ngati tipita patsogolo pakukonzekera, ndiye kuti ndi bwino kuganizira kuti ngakhale pa "mutu-wofiira" H22A7 / 8 Red pamwamba m'pofunika kuchita kunyamula. Mavavu ndi ndodo zolumikizira sizingasinthidwe, koma muyenera kuzimitsa mafuta ndikuyika ma shafts. Chotsatira ndi ma pistoni a Type S (11 compression), maupangiri amkuwa, ma poppet a titaniyamu, ma camshaft a Skunk2 Pro2, magiya, akasupe a valve a Skunk2, majekeseni a 360cc, ndi ubongo wa Hondata. Pambuyo kusintha komaliza, "mphamvu pa flywheel" adzakhala pafupifupi 250 hp.
Zachidziwikire, mutha kupita patsogolo ndikuzungulira 9000+ rpm, koma zonsezi ndizokwera mtengo ndipo kwa ambiri zimakhala zotsika mtengo kusintha galimoto kukhala yatsopano.
Chithunzi cha H22A
Pambuyo pa chingwe chovomerezeka cha silinda, kuyika kwa compression ratio ya 8.5-9 kumayikidwamo, ndodo zolumikizira zopepuka zokhala ndi zingwe zowoneka bwino, zotchingira zamkuwa za mavavu ndi akasupe ochokera ku Supertech, popanda mitsinje yolumikizana. Mufunikanso: makina opangira turbine, zida zamphamvu za ARP, pampu yamafuta ya Walbro 255, radiator ya mizere itatu yolumikizidwa ndi cholumikizira chakutsogolo, njanji yamafuta yokhala ndi chowongolera ndi majekeseni okhala ndi mphamvu ya 680 cc, valve blowoff, mapaipi, kutopa pa chitoliro cha 76 mm, ShPZ, sensor yamphamvu kwambiri komanso "ubongo" wa Hondata + cylinder head porting. Pamsonkhano womwewo, turbine ya Garrett T04e imatha kukwezedwa pansi pa 350 hp. ku 1 bar.
Pomaliza
H22A ndi gawo loyenera lamasewera lomwe lili ndi zovuta zake. Zovuta zoyamba zimayambira pamtunda wautali, pambuyo pa 150 kapena kupitilira makilomita zikwizikwi. Panthawi imodzimodziyo, zizindikiro zoyamba za "chowotcha mafuta" zimawonekera, ndipo chifukwa cha kuvala kwa injini, mphamvu zake zimatayika.
Pankhani ya maintainability, ndiyenera kunena kuti H-mndandanda si yabwino kwambiri pankhaniyi, komanso pafupifupi mzere wonse wa F-injini, kokha pa nkhani ya H22A n'zovuta kupeza galimoto m'malo. komanso magawo osowa komanso otsika mtengo kwambiri.
Pakukwanira kwake pakukonzekera, mzere wa H ndi wachiwiri kwa B-mndandanda ndipo kusiyana kwakukulu apa kuli mu bajeti. Kupatula apo, mutha kupanga H300A 22-ndiyamphamvu, koma mtengo wakukonzekera koteroko udzakhala kangapo kuposa zotsatira zomaliza pa injini zofananira za B.
