2SZ-FE injini
2SZ-FE ndi injini yamagetsi yamagetsi anayi, yomwe ili pamzere, yoziziritsa m'madzi yamafuta oyaka mkati. Makina ogawa gasi 16-vavu, ma valve anayi pa silinda, amasonkhanitsidwa molingana ndi dongosolo la DOHC.
Kusuntha kozungulira kuchokera ku crankshaft kumatumizidwa ku ma camshafts anthawi pogwiritsa ntchito unyolo. "Anzeru" VVT-I valavu dongosolo nthawi yawonjezeka kwambiri mphamvu ndi makokedwe poyerekeza ndi injini woyamba m'banja. Mulingo woyenera kwambiri pakati pa mavavu olowera ndi kutulutsa (chilembo F m'dzina), ndi makina ojambulira amagetsi amagetsi (chilembo E), adapanga 2SZ-FE kukhala ndalama zambiri kuposa zomwe zidalipo kale.

Ubwino ndi kuipa
Injini ya Toyota 2SZ-FE imakhalabe ndi mawonekedwe owoneka bwino omwe amafanana ndi mapangidwe a Daishitsu kuposa Toyota. Kumayambiriro kwa zaka za m'ma 2000, ambiri adapeza midadada yokhala ndi aluminiyamu yokhala ndi zipsepse zoziziritsa mpweya. Ubwino wosakayikitsa wa yankho lotere - kuphweka, choncho mtengo wotsika wa kupanga, komanso kulemera kochepa poyerekeza ndi injini za mpikisano, zinatipangitsa kuiwala chinthu chimodzi. Za maintainability.
2SZ-FE cast iron cylinder block block yapangidwa ndi mphamvu zokwanira komanso zakuthupi kuti zithe kukonzanso kwathunthu. Kutentha kochulukirapo kopangidwa ndi kugunda kwakutali kwa pistoni kumathetsedwa bwino ndi nyumba yayikulu ya injini. Nkhwangwa zazitali za silinda sizimalumikizana ndi olamulira a crankshaft, zomwe zimakulitsa kwambiri moyo wautumiki wa piston-cylinder pair.
Zowonongeka zimagwirizanitsidwa makamaka ndi mapangidwe osapambana a makina ogawa gasi. Zingawoneke kuti kuyendetsa unyolo kuyenera kupereka kudalirika kwakukulu komanso moyo wautali wautumiki, koma zonse zinasintha mosiyana. Kutalika kwa galimotoyo kunkafuna kuti pakhale maupangiri awiri am'maketani pamapangidwe, ndipo chotsitsa cha hydraulic chidakhala chokhudzidwa modabwitsa ndi mtundu wamafuta. Unyolo wamasamba wa kapangidwe ka Morse, pakumangika pang'ono, umalumphira pamapule, zomwe zimapangitsa kuti ma valve a valve pa pistoni akhudze.
Kukweza magalimoto okwera siwofanana ndi Toyota, koma mafunde opangidwa panyumba ya silinda. Zotsatira zake, zida zonse sizimalumikizana ndi mitundu ina ya injini, zomwe zimasokoneza kwambiri kukonza.
Chiwerengero cha ntchito
Mosiyana ndi injini zambiri za Toyota, 2SZ-FE idapangidwa kuti igwiritsidwe ntchito m'mabanja awiri okha - Toyota Yaris ndi Toyota Belta. "Omvera" opapatiza kwambiri amawonjezera mtengo wa injini yokhayokha komanso zida zosinthira. Ma injini a mgwirizano omwe amapezeka kwa eni ake ndi lotale, kupambana komwe kumadalira kwambiri mwayi kusiyana ndi zina, zodziwikiratu, makhalidwe.
Mu 2006, chitsanzo chotsatira cha mndandanda, injini ya 3SZ inatulutsidwa. Pafupifupi mofanana kwambiri ndi kuloŵedwa m'malo ake amasiyana voliyumu kuchuluka kwa malita 1,5 ndi mphamvu 141 ndiyamphamvu.
