Engine 2ZR-FE
Zamkatimu
Ma injini a ZR adawonekera kumapeto kwa 2006. M'chilimwe chotsatira, adayamba kupanga ndi Valvematic. Mmodzi wa iwo, injini 2ZR-FE, anayamba mu 2007, m'malo chitsanzo 1ZZ-FE.
Deta yaukadaulo ndi zothandizira
injini iyi ndi mzere "anayi" ndi makhalidwe a 2ZR-FE ndi motere:
| Chiwerengero | 1,8 l. |
| Kugwiritsa ntchito mphamvu | 132-140 l. Ndi. pa 6000 rpm |
| Mphungu | 174 Nm pa 4400 rpm |
| Chiyerekezo cha kuponderezana | 10.0:1 |
| Chiwerengero cha mavavu | 16 |
| Cylinder m'mimba mwake | 80,5 мм |
| Kupweteka kwa pisitoni | 88,3 мм |
| Kulemera | 97 makilogalamu |
Makhalidwe a unit ndi awa:
- DVVT dongosolo;
- mtundu ndi Valvematic;
- kukhalapo kwa hydraulic lifters;
- kuchepa kwa crankshaft.
Chida cha Toyota 2ZR-FE pamaso pa bulkhead ndi makilomita oposa 200 zikwi, zomwe nthawi zambiri zimakhala ndi m'malo mwa mphete zapistoni zolema kapena zomata.
chipangizo
Chophimba cha silinda chimapangidwa kuchokera ku ma aluminiyamu. Manja ali ndi nthiti zakunja, zomwe zimasakanikirana ndi zinthu za chipika kuti zikhale zogwirizana kwambiri ndi kutentha kwabwino. Chifukwa cha makulidwe a khoma la 7 mm pakati pa masilindala, palibe kukonzanso komwe kumawonekeratu.
The longitudinal axis wa crankshaft imachotsedwa ndi 8 mm pokhudzana ndi nkhwangwa za masilinda. Izi zotchedwa desaxage zimachepetsa kukangana pakati pa pisitoni ndi liner pamene kuthamanga kwakukulu kumapangidwa mu silinda.
Ma camshafts amayikidwa m'nyumba yosiyana yomwe imayikidwa pamutu wa block. Kuloledwa kwa ma valve kumasinthidwa ndi zonyamula ma hydraulic ndi tappets / rocker. Kuyendetsa nthawi ndi unyolo wa mzere umodzi (8 mm pitch) wokhala ndi hydraulic tensioner yomwe imayikidwa kunja kwa chivundikirocho.
Nthawi ya valve imasinthidwa ndi ma actuators omwe amaikidwa pa ma valve camshafts. Makona awo amasiyana pakati pa 55 ° (kulowetsa) ndi 40 ° (kutuluka). Ma valve olowera amasinthidwa mosalekeza pakukweza kwake pogwiritsa ntchito makina (Valvematic).
Pampu yamafuta imagwira ntchito kuchokera ku crankshaft pogwiritsa ntchito dera losiyana, lomwe ndilabwino kuyambira nthawi yozizira, koma limasokoneza kapangidwe kake. Bwaloli lili ndi ma jet amafuta omwe amaziziritsa komanso amapaka ma pistoni.
Zochita ndi Zochita
Chuma chagalimoto chokhala ndi injini ya 2ZR-FE chimavoteledwa bwino. Imakhala ndi mowa wochepa pamsewu waukulu, komabe, malingana ndi kutentha kwa kunja. Kumwa kumakhudzidwanso ndi kuphatikizika komwe kumakhala kosintha bwino kwambiri pankhaniyi, ndikuphatikizidwa ndi kufala kwamotoko, injiniyo ikuwonetsa "chapakati" bwino.
Ndi kuwonjezeka kwa liwiro, camshaft imayenda mozungulira motsatana ndi pulley. Makamera a mawonekedwe apadera, pamene shaft imatembenuzidwa, ma valve olowetsa amatsegula pang'ono, ndikutseka pambuyo pake, zomwe zimawonjezera N ndi Mcr pa liwiro lalikulu.
Injini ali ndi sitiroko pisitoni 88,3 mm, kotero Vav wake = 22 m / s pa katundu oveteredwa. Ngakhale ma pistoni opepuka samawonjezera moyo wagalimoto. Inde, ndipo kuchuluka kwa mafuta ochulukirapo kumalumikizidwanso ndi izi.
Pachitsanzo ichi, m'pofunika kusintha unyolo wa nthawi pambuyo pa makilomita 150, zingakhale bwino pamodzi ndi mbali zina, popeza ma sprocket akale amatha msanga unyolo watsopano. Koma popeza ma sprockets a camshaft amapangidwa nthawi imodzi ndi ma drive a VVT okwera mtengo ndipo samasinthidwa padera, kusintha unyolo kokha kumachita pang'ono.
Malo opingasa a fyuluta yamafuta ndizachisoni, chifukwa mafuta amayenda kuchokera pamenepo kupita ku crankcase injini ikazimitsidwa, zomwe zimawonjezera nthawi yokweza kukakamiza kwamafuta poyambira kwatsopano.
Palinso kuipa kotere:
- zovuta zoyambira ndi kusokoneza;
- zolakwika zachikhalidwe za EVAP;
- kutayikira ndi phokoso la pampu yozizira;
- mavuto ndi kukakamizidwa XX;
- Kuvuta koyambira kotentha, etc.
Kulembetsa magalimoto okhala ndi injini ya 2ZR-FE
Magalimoto otsatirawa ali ndi magetsi awa:
- Toyota Allion?
- Toyota Premium;
- Toyota Corolla, Corolla Altis, Axio, Fielder;
- Toyota Auris;
- Toyota Yaris;
- Toyota Matrix / Pontiac Vibe (USA);
- Scion XD.
Injini iyi ikulonjeza: idzakhazikitsidwa pa Toyota Corolla yatsopano pamodzi ndi chitsanzo cha 2ZR-FAE.
