Subaru Impreza engines
Zamkatimu
Mtundu womwe mafani ambiri amalumikizana nawo kwambiri ndi masewera agalimoto ndi Subaru Impreza. Ena amawona ngati chitsanzo cha kukoma kotsika mtengo, ena - maloto omaliza. Komabe, kuwirikiza kwa mfundo sikutsutsana ndi mfundo yaikulu yakuti sedan yodziwika bwino ili ndi khalidwe lapadera.
The kuwonekera koyamba kugulu m'badwo woyamba Impreza (ngolo ndi sedan) zinachitika mu 1992. Zaka ziwiri pambuyo pake, chitsanzo cha coupe chinaperekedwa ku khoti la oyendetsa galimoto, ngakhale kuti chinali chochepa kwambiri. Pamndandanda wa Subaru, Impreza idatenga mwachangu niche yopanda kanthu yomwe idapangidwa pakati pa mitundu ya Justy ndi Legacy.
Mapangidwewo adachokera pa nsanja yofupikitsidwa ya omwe adatsogolera - "Cholowa" chomwe chatchulidwa kale. Poyamba, cholinga chachikulu cha ntchitoyi chinali kupanga galimoto yopanga - "m'munsi" wophunzira, ndipo mwina ngwazi ya WRC World kusonkhana. Zotsatira zake, galimoto yowala komanso yosakhala yachilendo idawonekera, mawonekedwe ake odziwika bwino omwe adamupatsa kuzindikira kwakukulu kwa ogula.
Subaru Impreza engines
Magalimoto ali ndi injini za boxer four-cylinder za kusintha kwa EJ m'mitundu yosiyanasiyana. Mabaibulo osavuta a "Impreza" adalandira 1,6-lita "EJ16" ndi 1,5-lita "EJ15". Mitundu yapamwamba kwambiri, yotchedwa "Impreza WRX" ndi "Impreza WRX STI", inali ndi turbocharged "EJ20" ndi "EJ25", motsatira. Pa zitsanzo ofooka a m'badwo wachitatu anaika mphamvu ya EL15 lita imodzi ndi theka kapena awiri lita boxer injini dizilo.
Mtundu wachinayi wa Subaru Impreza "okhala ndi zida" 2-lita "FB20" ndi 1,6-lita "FB16", ndi zosintha masewera a galimoto - "FA20" ( "WRX") ndi "EL25" / "EJ20" ("WRX STI") motsatana. Momveka bwino zambiri izi zaperekedwa mu tebulo 1-5.

Zojambulajambula ndi zovuta zomwe zimachitika
Magawo amagetsi omwe amaikidwa pamagalimoto a Impreza, monga makina aliwonse ovuta, ali ndi zofooka zomwe zimangokhala:
- Pafupifupi zosintha zonse za EJ20, posakhalitsa kugogoda kumawonekera mu silinda yachinayi. Chifukwa cha zochitika zake ndi kupanda ungwiro kwa mapangidwe a dongosolo lozizira. Chofunika kwambiri ndi nthawi ya kugogoda. Chiwonetsero chachifupi cha chizindikirochi mkati mwa mphindi zitatu mutayamba ndizochitika nthawi zonse, pamene kugwedeza kwa mphindi 3 kwa injini yotenthedwa bwino ndi chizindikiro cha kukonzanso kumene kuli pafupi.
- Mipando yakuzama ya mphete za pistoni, kuyambitsa kuchuluka kwamafuta (mumitundu yokhala ndi turbocharger).
- Kuwonjezeka kwa kuvala ndi kusewera kwa zisindikizo za camshaft ndi zophimba za valve zomwe zimapangitsa kuti mafuta azituluka. Kuchotsa mosayembekezereka kwavuto lotere kungayambitse kutsika kwamafuta m'dongosolo, motero, njala yamafuta ya injini.
- Magawo amagetsi a EJ25 ali ndi makoma ocheperako poyerekeza ndi mitundu ina ya injini zoyatsira mkati, zomwe zimawonjezera chiwopsezo cha kutenthedwa, kupunduka mutu wa silinda ndi kutayikira kwa gasket.
- Zosintha EJ257 ndi EJ255 nthawi zambiri "zimavutika" kutembenuza ma liner.
- Ma FB20 ndiwodziwikiratu pakuwonongeka kothandizira chifukwa chakukhudzidwa kwambiri ndi kuchuluka kwamafuta komanso mtundu wamafuta. Komanso, injini chopangidwa pamaso 2013 nthawi zambiri ndi zolakwika zazikulu mu chipika yamphamvu.
Zothandizira ndi kudalirika
Ubwino waukulu wa magetsi a Subaru Impreza ndiwokhazikika bwino, mphamvu zambiri, kugwedezeka kochepa komwe kumayenderana ndi ntchitoyo, komanso chida chachitali. Zochita zimasonyeza kuti ambiri mwa injini kuyaka mkati anaika pa "Impreza" popanda kukonzanso lalikulu 250 - 300 makilomita zikwi.
Komabe, tisaiwale kuti mawu amenewa si ntchito turbocharged masewera magalimoto injini. Zosintha zonse za mayunitsiwa zimayendetsedwa ndi katundu wambiri, zomwe nthawi zambiri zimatsogolera ku bulkhead pambuyo pa 120 - 150 zikwi zikwi. Palinso milandu yovuta kwambiri pamene kubwezeretsa galimoto sikutheka mwaukadaulo.
Mlingo wapamwamba kwambiri wodalirika uli ndi magetsi, kuchuluka kwa ntchito komwe sikufika malita awiri: EJ18, EJ16 ndi EJ15. Komabe, injini za malita awiri ndizodziwika kwambiri chifukwa zimakhala zamphamvu kwambiri.
Malinga ndi mainjiniya - opanga nkhawa ya Subaru, mitundu ya FB imapatsidwa gwero lowonjezeka ndi lachitatu.
Pomaliza - zotsatira za kafukufuku wa akatswiri ndi mafani a Subaru Impreza magalimoto, cholinga kudziwa injini yabwino. Gawo lalikulu kwambiri lazomwe zakwera kwambiri zidapezedwa ndi injini za SOHS za malita awiri: EJ20E, EJ201, EJ202.
