Injini yeToyota 1ZZ
IMVELISO INTSHAYELELO
IToyota ye-1.8-litha1ZZ-FEInjini yaveliswa kwiplanti yaseKhanada ukusuka ngo-1997 ukuya ku-2009 kwaye yafakwa kwiimodeli zenkampani zaseJapan ezidumileyo njengeCorolla, Matrix kunye neAvensis. Kukho inguqulelo yeyunithi yamandla ye-ethanol kwimarike yaseBrazil kunye nesalathisi 1ZZ-FBE.
Le njini yaphuhliswa i-American Corolla yaza yadityaniswa eKhanada ukusuka ngo-1997 ukuya ku-2009. Uyilo lwaluqhelekile: ibhloko ye-aluminiyam eyi-4-cylinder ene-cast-iron liners, i-16-valve ye-aluminium block head with two camshafts and no hydraulic lifters. Ukuqhuba ixesha lenziwa ngekhonkco, kwaye ngo-1999 umlawuli wesigaba sohlobo lweVVT-i wabonakala kwindawo yokungena.
Iinjineli zazama ukwenza idizayini ibe lula ngokusemandleni, kunye nejacket yokupholisa evulekileyo, i-T-piston encinci ye-long-stroke kunye ne-alloy block ene-crankcase eyahlukileyo. Konke oku ngokwemvelo akubangeli igalelo ekuthembekeni kweyunithi yamandla kunye nokunciphisa ubutyebi bayo.
Injini yeToyota 1ZZ-FED yaveliswa kwiShimoyama Plant ukusuka ngo-1999 ukuya ku-2007 kwiimodeli ezinophawu lwezemidlalo, olufana noCelica okanye uMR2. Le yunithi yahluke kwinguqu eqhelekileyo ye-1ZZ-FE ngentloko ye-cylinder eyahlukileyo kunye necandelo elikhulu lomnqamlezo.

Iingxaki rhoqo
1.Injini itya ioyile eninzi. Isizathu - amakhonkco e-oil scraper ephukile (ingakumbi ukukhululwa ngaphambi kwe-2002). I-Decarbonization, njengomthetho, ayisombululi ingxaki.
2.Nqonkqoza ngaphakathi kwiyunithi. Ikhonkco lexesha likhululiwe, okubalulekileyo emva kokudlula ngaphezu kwe-150 yeekhilomitha eziliwaka. Isixhobo sokuthambisa ibhanti sisenokuba nesiphene. Iivalvu azinkqonkqozi.
3.Iinguqu zandanda. Gubha i-throttle-gate kunye ne-valve compartment ngesantya esingasebenziyo.
4.Ukungcangcazela. Mhlawumbi i-cushion yangasemva inetyala, okanye oku kukodwa kwemoto ye-1ZZ.
Ukongezelela, iyunithi isabela kakubi ekugqithiseni. Ngenxa yoko, isakhiwo se-cylinder block siyancipha, esifuna ukutshintshwa kwayo ngokupheleleyo (umgca kunye nokugaya akwenziwanga ngokusemthethweni). Iinguqulelo ze-injini ezikhutshwe emva ko-2005, ngakumbi ngeekhilomitha ezingaphantsi kwama-200 amawaka eekhilomitha, zineempawu ezintle kakhulu zokusebenza.
