Toyota 2S, 2S-C, 2S-E, 2S-ELU, 2S-EL, 2S-E
Ma injini a Toyota 1S anali otchuka ku Japan ndi mayiko ena ambiri. Koma pamsika waku America, Canada, Australia, magalimoto okhala ndi injini zamphamvu kwambiri adafunikira. Pankhani imeneyi, mu 1983, mofanana ndi injini 1S, anayamba kupanga injini ndi linanena bungwe apamwamba pansi dzina 2S. Akatswiri opanga ma Toyota Corporation sanasinthe kwenikweni pamapangidwe a kholo lomwe limakhala lopambana, kudziletsa kukulitsa kuchuluka kwa ntchito.
Kupanga injini ya 2S
Chipangizocho chinali injini yamasilinda anayi okhala ndi mphamvu ya 1998 cm3. Kuwonjezeka kunachitika powonjezera kukula kwa silinda mpaka 84 mm. pisitoni sitiroko anasiyidwa chimodzimodzi - 89,9 mm. Galimotoyo idakhala yocheperako nthawi yayitali, sitiroko ya pisitoni idayandikira pafupi ndi m'mimba mwake. Kukonzekera uku kumapangitsa kuti injiniyo ifike ku ma RPM apamwamba ndikusunga mphamvu zolemetsa pama RPM apakati.
Injini idayikidwa motalika. Zida zamutu wa block ndi aluminiyamu alloy. Chidacho chimapangidwa ndi chitsulo chonyezimira. Silinda iliyonse ili ndi ma valve awiri, omwe amayendetsedwa ndi camshaft imodzi. Ma compensators a hydraulic amaikidwa, zomwe zimapangitsa kuti injiniyo isakhale ndi phokoso ndikuchotsa kufunikira kwa kusintha kwanthawi ndi nthawi kwa ma valve.
Dongosolo lamphamvu ndi poyatsira limagwiritsa ntchito carburetor yachikhalidwe komanso yogawa. Kuyendetsa nthawi kumayendetsedwa ndi belt drive. Kuwonjezera pa camshaft, lamba ankayendetsa mpope ndi pampu yamafuta, chifukwa chake idakhala yayitali kwambiri.
Injini yoyaka mkati idatulutsa 99 ndiyamphamvu pa 5200 rpm. Mphamvu yochepa ya injini ya-lita-lita ndi chifukwa cha chiwerengero chochepa cha psinjika - 8,7: 1. Izi zimatheka chifukwa cha zotsekera m'munsi mwa pistoni, zomwe zimalepheretsa ma valve kukumana ndi pistoni pamene lamba wathyoka. Makokedwe anali 157 N.m pa 3200 rpm.
Mu 1983 yemweyo, gawo la 2S-C lokhala ndi chosinthira chosinthira mpweya wotulutsa zidawonekera mugawo. ICE imagwirizana ndi miyezo ya kawopsedwe yaku California. Kutulutsidwa kunakhazikitsidwa ku Australia, komwe Toyota Corona ST141 idaperekedwa. Magawo a injini iyi anali ofanana ndi a 2S.
Kusinthidwa kotsatira kunali injini ya 2S-E. Carburetor yasinthidwa ndi jekeseni wamagetsi wa Bosch L-Jetronic. Chipangizocho chinayikidwa pa Camry ndi Celica ST161. Kugwiritsa ntchito jekeseni kunapangitsa kuti injiniyo ikhale yotanuka komanso yotsika mtengo kuposa carburetor, mphamvu yowonjezereka mpaka 107 hp.
Injini yomaliza pamndandandawu inali 2S-ELU. Galimotoyo idayikidwa mopingasa pa Toyota Camry V10 ndipo ikugwirizana ndi miyezo yapoizoni yomwe idakhazikitsidwa ku Japan. Mphamvu iyi idapangidwa ndi 120 hp pa 5400 rpm, yomwe inali chizindikiro choyenera pa nthawiyo. Kupanga injini kunatenga zaka 2, kuyambira 1984 mpaka 1986. Kenako panabwera mndandanda wa 3S.
Ubwino ndi kuipa kwa mndandanda wa 2S
Ma motors a mndandandawu adatengera mbali zabwino ndi zoyipa za omwe adawatsogolera, 1S. Mwa ubwino, iwo amaona gwero wabwino (mpaka 350 zikwi Km), maintainability, bwino ndi ntchito yosalala, kuphatikizapo zikomo onyamula hayidiroliki.
Zoyipa zake ndi:
- lamba lalitali kwambiri komanso lodzaza, lomwe limatsogolera kusweka pafupipafupi kapena kusamuka kwa lamba pokhudzana ndi zikhomo;
- zovuta kusamalira carburetor.
Ma motors anali ndi zofooka zina, mwachitsanzo, wolandila mafuta wautali. Zotsatira zake - njala yamafuta ochepa a injini panthawi yozizira imayamba.
