Injini 2ZR-FE
Okuqukethwe
Izinjini zochungechunge lwe-ZR zavela ekwindla ka-2006. Ehlobo elilandelayo, zaqala ukukhiqizwa kwazo kwe-serial nge-Valvematic. Omunye wabo, injini 2ZR-FE, eyasungulwa ngo-2007, esikhundleni imodeli 1ZZ-FE.
Idatha yobuchwepheshe nensiza
Le moto iyi-in-line "ezine" futhi izici ze-2ZR-FE zimi kanje:
| Ububanzi | I-1,8 l. |
| Amandla | 132-140 l. Nge. ngo-6000 rpm |
| I-Torque | 174 Nm ku-4400 rpm |
| Isilinganiso sokucindezela | 10.0:1 |
| Inani lama-valve | 16 |
| Ububanzi besilinda | 80,5 mm |
| Ukushaya kwesibhamu | 88,3 mm |
| Isisindo | I-97 kg |
Izici zeyunithi zihlanganisa:
- Uhlelo lwe-DVVT;
- inguqulo nge-Valvematic;
- ukuba khona kwama-hydraulic lifters;
- ukuchithwa kwe-crankshaft.
Insiza ye-Toyota 2ZR-FE ngaphambi kwe-bulkhead ingaphezu kwezinkulungwane ezingama-200 km, ngokuvamile ehlanganisa ukufaka amasongo e-piston agugile noma anamathele.
Idivayisi
I-cylinder block ifakwe ku-aluminium alloys. Imikhono inohlangothi lwangaphandle olunezimbambo, ezihlanganiswa nezinto zebhulokhi ukuze kuxhunywe okuqinile nokuthuthukiswa kokushisa kokushisa. Ngenxa yobukhulu bodonga obungu-7 mm phakathi kwamasilinda, akukho ukulungisa okubonwa kusengaphambili.
I-axis ye-longitudinal ye-crankshaft isuswa ngo-8 mm uma kuqhathaniswa nezimbazo zamasilinda. Lokhu okubizwa nge-desaxage kunciphisa ukungqubuzana phakathi kwe-piston kanye ne-liner lapho ukucindezela okukhulu kwakhiwa kusilinda.
Ama-camshaft abekwe endaweni ehlukile ebekwe ekhanda lebhulokhi. Ukucaciswa kwama-valve kulungiswa iziphakamisi ezingama-hydraulic kanye nama-roller tappets/ama-rocker. Idrayivu yesikhathi iyiketango lomugqa owodwa (8 mm pitch) eline-hydraulic tensioner efakwe ngaphandle kwekhava.
Isikhathi se-valve sishintshwa ama-actuator afakwe kuma-valve camshafts. Ama-engeli azo ahluka phakathi kuka-55° (i-inlet) kanye no-40° (i-outlet). Ama-valve okungenisa ashintshwa ngokuqhubekayo ekuphakameni kokuphakama kusetshenziswa isistimu (Valvematic).
Iphampu kawoyela isebenza kusukela ku-crankshaft isebenzisa isekethe ehlukile, enhle uma iqala ebusika, kodwa yenza umklamo ube nzima. Ibhulokhi ifakwe amajethi kawoyela apholile futhi agcobe amapiston.
Izinzuzo nezingozi nebubi
Umnotho wemoto enenjini engu-2ZR-FE ukalwe kahle. Inokusetshenziswa okuphansi emgwaqeni onguthelawayeka, noma kunjalo, kuye ngezinga lokushisa langaphandle. Ukusetshenziswa kuphinde kuthinteke ukuhlanganisa nge-variator esebenza kahle kakhulu kulokhu, futhi kubhangqiwe nokudluliswa okuzenzakalelayo, injini ikhombisa ukusebenza kahle "okumaphakathi".
Ngokunyuka kwejubane, i-camshaft ihamba ngendlela ye-angular ngokuphathelene ne-pulley. Amakhamera anesimo esikhethekile, lapho i-shaft iphendulwa, ama-valve okungena avuleka kancane kancane, futhi avale kamuva, okwandisa i-N ne-Mcr ngesivinini esikhulu.
Injini ine-piston stroke engu-88,3 mm, ngakho-ke i-Vav yayo = 22 m / s ngomthwalo olinganiselwe. Ngisho nama-piston alula awakhulisi impilo yemoto. Yebo, futhi ukwanda kwemfucuza yamafutha nakho kuhlotshaniswa nalokhu.
Kulo modeli, kuyadingeka ukushintsha uchungechunge lwesikhathi ngemva kwamakhilomitha ayizinkulungwane ezingu-150, kungaba ngcono kanye nezinye izingxenye, ngoba ama-sprockets amadala aguga ngokushesha iketango elisha. Kodwa njengoba ama-sprockets e-camshaft enziwa ngasikhathi sinye ngamadrayivu e-VVT abizayo futhi awashintshiwe ngokuhlukana, ukushintsha kuphela iketango akwenzi okuncane.
Indawo evundlile yesihlungi sikawoyela ayijabulisi, ngoba uwoyela ugeleza usuka kuwo uye ku-crankcase lapho injini icishiwe, okwandisa isikhathi sokunyusa umfutho kawoyela ekuqaleni okusha.
Kukhona futhi ukungalungi okunjalo:
- ukuqala okunzima nokungaphumeleli;
- amaphutha endabuko EVAP;
- ukuvuza kanye nomsindo wepompo yokupholisa;
- izinkinga nge-XX ephoqelelwe;
- ubunzima bokuqala obushisayo, njll.
Irejista yezimoto ezinenjini engu-2ZR-FE
Izimoto ezilandelayo zinalesi sikhungo sikagesi:
- Toyota Allion?
- Toyota Premium;
- Toyota Corolla, Corolla Altis, Axio, Fielder;
- Toyota Auris;
- Toyota Yaris;
- Toyota Matrix / Pontiac Vibe (USA);
- I-Scion XD.
Le njini iyathembisa: izofakwa kwiToyota Corolla entsha kanye nohlobo lwe-2ZR-FAE.
