2RZ-E thiab 2RZ-FE cav
Txheem
Lub 2-liter plaub-lub tog raj kheej 2.4RZ cav pib muab ntsia rau Toyota HIACE WAGON tsheb nyob rau hauv lub yim hli ntuj 1989. Thaum tsim lub hwj chim units ntawm RZ series nrog serial tooj 1 thiab 2, ib tug technical platform tau siv. Kev nce hauv lub zog hauv 2RZ cov cav tau ua tiav los ntawm kev ua kom lub ntim ntawm cov combustion chambers thiab siv cov kab loj dua pistons.
Xyoo 1995, lub cav 2RZ tau hloov kho kom siv lub tog raj kheej kheej kheej kheej kheej, ua rau 16-valve 2RZ-FE ICE. Kev siv qhov kev npaj no ua rau nws muaj peev xwm ua tiav qhov tseem ceeb ntawm lub zog thiab kev sib tw ntawm lub cev muaj zog.
Lub coding ntawm 2RZ-E thiab 2RZ-FE cav muaj yuav luag tiav cov ntaub ntawv hais txog tus tsim nta thiab hom hwj chim units:
- "2" yog tus naj npawb ntawm lub cav nyob rau hauv ib series;
- "R" yog qhov kev xaiv dav dav ntawm koob, uas txiav txim siab hom cav: nyob rau hauv-kab plaub-lub tog raj kheej sab hauv combustion engine nrog lub sij hawm saw tsav;
- "Z" - ib tug kos npe rau ntawm ib tug roj av cav;
- "E" - ib tug kos npe rau ntawm lub internal combustion engine zog system: hluav taws xob multi-point txhaj;
- "F" yog ib tug kos npe rau ntawm tus naj npawb ntawm li qub thiab layout ntawm lub camshafts nyob rau hauv lub tog raj kheej taub hau: 4 li qub rau ib lub tog raj kheej, tus qauv "nqaim" layout nrog ib tug saw tsav ib camshaft.

Kev siv tau ntawm cov tsheb
Lub cav 2RZ-E tau siv rau hauv cov qauv hauv qab no Toyota:
- HIACE WAGON 08.1989-08.1995 thiab 08.1995-07.2003;
- HIACE ROYAL 08.1995-07.2003;
- HIACE COMMUTER 08.1998-07.2003.
Lub cav 2RZ-FE tau siv rau Toyota tsheb destined rau European thiab North American lag luam:
- HILUX 08.1997-08.2001 (Tebchaws Europe);
- TACOMA 01.1995-09.2004 (USA)
Cov yam ntxwv ntawm kev ua haujlwm thiab kev saib xyuas
Nyob rau hauv Russia, 2RZ-E thiab 2RZ-FE cav yog heev tsawg, yog li nws yog ib qhov nyuaj rau nrhiav tau tej yam tseem ceeb xyuas rau lawv. Hauv tsev, hauv Nyij Pooj, cov cav no tseem tsis tau nthuav dav, txawm tias qee qhov nce hauv lub zog piv rau thawj cov qauv ntawm cov koob hauv qab cov lej 1RZ. Feem ntau, qhov no yog vim qhov nce qib ntawm kev co hauv 2RZ motors, cuam tshuam nrog cov qauv tsim ntawm plaub inline. Nyob rau hauv peb cov qauv ntawm cov series ntawm 2.7-liter engine, qhov teeb meem no tau raug tshem tawm los ntawm kev siv ib tug complex balancing mechanism nyob rau hauv lub taub hau ntawm lub BC, thiab nyob rau hauv lub ICE nrog ib tug ntim ntawm 2.4 litres, Toyota designers tsis muab rau xws li cov nyiaj them.
Txij li thaum lub 2RZ thiab 1RZ xyaw yog structurally ze heev thiab tau tsim yuav luag ib txhij, lawv cov yam ntxwv nta yeej coincide. Qhov zoo ntawm 2RZ lub cav, zoo li cov 1RZ, suav nrog kev siv roj, kev ntseeg siab, kev ua haujlwm yooj yim thiab kev saib xyuas, thiab lub neej ua haujlwm ntev. Qhov tsis zoo, ntxiv rau qhov nce qib ntawm kev vibrations, yog qhov tseem ceeb ntawm cov cav no rau qhov zoo thiab qhov xwm txheej ntawm cov roj cav thiab qhov kev pheej hmoo ntawm kev puas tsuaj rau li qub thiab pistons thaum lub voj voog tawg.
Qhov tsis ua tiav ntawm txoj kev loj hlob thiab qhov kawg tuag ntawm kev txhim kho ntxiv ntawm 2RZ lub cav tsev neeg kuj yog pov thawj los ntawm qhov tseeb tias cov cav ntawm RZ series nrog lub ntim ntawm 2.0 litres (1RZ) thiab 2.7 litres (3RZ) tau hloov los ntawm cov cav. ntawm TR series tshiab, zoo sib xws hauv kev tsim, ntxiv los ntawm cov khoom siv niaj hnub thiab cov khoom siv, tab sis qhov no tsis tshwm sim nrog 2.4 l kab.
