Toyota 2S, 2S-C, 2S-E, 2S-ELU, 2S-EL, 2S-E izinjini
Okuqukethwe
Izinjini ze-Toyota 1S zazidumile eJapane nakwamanye amazwe amaningi. Kodwa emakethe yaseMelika, eCanada, e-Australia, kwakudingeka izimoto ezinenjini enamandla kakhulu. Kulokhu, ngo-1983, ngokuhambisana nezinjini ze-1S, kwaqala ukukhiqizwa injini enezinga eliphakeme ngaphansi kwegama elithi 2S. Onjiniyela bakwaToyota Corporation abenzanga izinguquko eziyisisekelo ekwakhiweni kokhokho abaphumelela ngokuvamile, bazibekela umkhawulo ekwandiseni umthamo wokusebenza.
Ukwakhiwa kwenjini ye-2S
Iyunithi bekuyinjini ye-four-cylinder enevolumu yokusebenza engu-1998 cm3. Ukwenyuka kufinyelelwe ngokukhuphula ububanzi besilinda bufinyelele ku-84 mm. Ukushaywa kwe-piston kwasala okufanayo - 89,9 mm. I-motor ayizange ibe ne-stroke emide, i-piston stroke yasondezwa eduze kobubanzi besilinda. Lokhu kulungiselelwa kuvumela injini ukuthi ifinyelele ama-RPM aphezulu futhi igcine umthamo womthwalo kuma-RPM aphakathi.
Injini yafakwa ngobude. I-block head material i-aluminium alloy. Ibhulokhi lenziwe ngensimbi eyinsimbi. Isilinda ngasinye sinama-valve amabili, ashayelwa i-camshaft eyodwa. Izinxephezelo ze-Hydraulic zifakiwe, okwenza imoto ingabi nomsindo futhi iqede isidingo sokulungiswa ngezikhathi ezithile kokucaciswa kwama-valve.
Amandla kanye nesistimu yokuthungela isebenzise i-carburetor yendabuko kanye nomsabalalisi. Ukushayela isikhathi kwenziwa nge-belt drive. Ngaphandle kwe-camshaft, ibhande lalishayela iphampu kanye nepompo likawoyela, yingakho liphenduke lide kakhulu.
Injini evuthayo yangaphakathi ikhiqize amandla angu-99 ku-5200 rpm. Amandla aphansi enjini enamalitha amabili ngenxa yesilinganiso esiphansi sokucindezela - 8,7: 1. Lokhu ngokwengxenye kubangelwa ukushona phansi kwamapiston, okuvimbela ama-valve ukuthi angahlangani namapiston lapho ibhande ligqashuka. I-torque yayingu-157 N.m ku-3200 rpm.
Ngawo lowo 1983, iyunithi 2S-C ifakwe exhaust gas catalytic Converter kwavela iyunithi. I-ICE ingena ezindinganisweni zobuthi zaseCalifornia. Ukukhishwa kwasungulwa e-Australia, lapho iToyota Corona ST141 yethulwe khona. Amapharamitha ale motor ayefana nalawo e-2S.
Ukuguqulwa okulandelayo kwaba injini ye-2S-E. I-carburetor ithathelwe indawo umjovo we-elekthronikhi we-Bosch L-Jetronic. Iyunithi yafakwa ku-Camry naku-Celica ST161. Ukusetshenziswa kwe-injector kwenza injini ikwazi ukunwebeka futhi iyonga kakhulu kune-carburetor, amandla akhuphukela ku-107 hp.
Injini yokugcina ochungechungeni kwakuyi-2S-ELU. Injini yafakwa ngokuphambana kwiToyota Camry V10 futhi yangena ezindinganisweni zobuthi ezamukelwa eJapan. Le yunithi yamandla ikhiqize i-120 hp ku-5400 rpm, okwakuyinkomba efanele ngaleso sikhathi. Ukukhiqizwa kwemoto kwathatha iminyaka engu-2, kusukela ngo-1984 kuya ku-1986. Kwabe sekufika uchungechunge lwe-3S.
Izinzuzo kanye nokubi kochungechunge lwe-2S
Amamotho alolu chungechunge azuze izinhlangothi ezinhle nezingezinhle zomanduleli wawo, i-1S. Phakathi kwezinzuzo, baphawula insiza enhle (kufika ku-350 XNUMX km), ukugcinwa, ibhalansi nokusebenza okubushelelezi, okuhlanganisa ukubonga kwama-hydraulic lifters.
Okubi yilezi:
- ibhande elide kakhulu futhi elilayishiwe, eliholela ekuqhekekeni noma ekuthuthweni kwebhande elihlobene namamaki;
- kunzima ukugcina i-carburetor.
Ama-motor ayenamanye amaphutha, isibonelo, isamukeli samafutha eside. Ngenxa yalokho, indlala yesikhashana kawoyela yenjini ngesikhathi esibandayo iqala.
