Nissan KA20DE cav
Lub KA20DE roj av cav nrog ib tug ntxaib-ncej lub tog raj kheej taub hau tshwm nyob rau hauv 1991 raws li ib tug hloov rau 2,0-liter Z20 (OHC NA20S nyob rau hauv lub thib ob tiam Nissan Atlas). Cov saw hlau yog siv rau hauv kev tsav tsheb ntawm nws cov roj faib tshuab (lub sijhawm) (lub tshuab saw hlau, uas yog qhov txawv ntawm kev hnav tsis kam, kev ua haujlwm ntsiag to, tsis kam mus rau qhov kub thiab txias, tsis muaj kev ntseeg siab ntau dua li cov roj hmab toothed siv).
Nws qhov kev hloov pauv yog qhov tshwm sim tsis tshua muaj tshwm sim, feem ntau tshwm sim tom qab kev khiav ntau dua 300 txhiab km (nws raug nquahu kom ua qhov kev tiv thaiv tom qab 100 txhiab km). Qhov tseem ceeb hnav manifests nws tus kheej nyob rau hauv daim ntawv ntawm:
- suab nrov,
- tensioner qws qhov hluav taws xob
- valve sij hawm ua haujlwm vim cov saw dhia los ntawm 1 - 2 cov hniav (tshwj xeeb los ntawm computer diagnostics).
Kev hloov ntawm cov saw hlau yuav tsum tau ua raws li kev sib tw ntawm lub sijhawm sib tw (kev teeb tsa nrog cov cim ntawm cov saw txuas offset txheeb ze rau cov cim ntawm lub zog ntawm lub crankshaft thiab camshafts tuaj yeem ua rau lub cav tsis ua haujlwm).
Npav
Lub npe KA20DE sawv cev rau:
KA - Cav series (los ntawm kab hauv kab 4-lub tog raj kheej),
20 - Ntim (2,0 litres),
D - Lub cav nrog ob lub taub hau camshafts (DOCH),
E - Hluav taws xob txhaj tshuaj.
Nissan KA series yog sawv cev los ntawm KA20DE, KA24E thiab KA24DE units. Ntawm qhov zoo, nws yog tus cwj pwm los ntawm kev yooj yim, kev ntseeg siab, ua haujlwm ntev, ntawm qhov tsis zoo - kev siv roj kuj tseem ceeb (rau KA20DE, 100 - 12 litres roj av tau hlawv ib 15 km hauv nroog hom, 8 - 9 litres hauv kev loj. hom, nyob rau hauv sib xyaw (10/15) - 10,5 l) thiab complexity ntawm kev kho thiab tu (tshwj xeeb tshaj yog nyob rau hauv kev sib piv nrog rau Toyota), uas yog txuam nrog ib tug heev ntom "packing" ntawm nodes nyob rau hauv lub hood.
Cov peev txheej ntawm lub cev muaj zog hais txog kev ntseeg siab thiab ua haujlwm ntev ntawm lub cav - nws tsis tuaj yeem nrhiav cov ntaub ntawv ntawm lub Hoobkas, hauv kev xyaum, piv txwv li, rau Nissan Caravan, nws hloov tawm ntau dua 300 txhiab kilometers (txoj kev kho uas tshem tawm txog 200. hp los ntawm lub log - txhim kho cov khoom noj khoom haus, throttle dampers, camshafts nrog springs, lub tog raj kheej taub hau porting, lub teeb yuag forged pistons rau siab dua (~ 11) compression piv thiab txuas rods, injectors ... - nws hloov tawm ntau tshaj 350 txhiab km ).
Lub cav ntsuas raws li drive2.ru yog 4+.
Tsheb nrog KA20DE cav
Lub cav combustion sab hauv (ICE) KA20DE tau teeb tsa rau ntawm Nissan cov qauv hauv qab no (tus naj npawb raug xuas nrig los ntawm sab ntawm lub tso pa tawm ntawm qhov sib txuas ntawm lub cav thiab lub thawv):
- Atlas 10 2000 Super Low GE-SH4F23 (1999-2002), TC-SH4F23 (2003-2005), H2F23 (1999-2003);
- Caravan GE-VPE25 (2001 г.), LC-VPE25 (2005 г.);
- Datsun GC-PD22 (1999 - 2001);
as well as on Isuzu COMO GE-JVPE25-S48D 2001 - 2003, Isuzu ELF ASH2F23, Isuzu Fargo JVPE24.
Tag nrho cov tsheb uas tau teev tseg yog tus cwj pwm los ntawm cov ntsiab lus tsis tshua muaj teeb meem hauv cov pa roj - lub cav yog nruab nrog LEV system (E-LEV Performance index - emissions yog 50% huv dua li 2000, 2005 qauv). Chav tsev khiav ntawm qhov sib xyaw ntawm huab cua thiab roj av nrog qhov sib piv ntawm 40: 1.

Lub ntim ntawm curled roj yog 4,1 litres. Kev hloov pauv tau pom zoo tom qab 7 - 500 km (kev siv yog kwv yees li 15 g ib 000 km). Lub cav yog rhiab heev rau qhov zoo - koj yuav tsum xaiv tus thawj los ntawm "rau roj av" series nrog viscosity ntawm 500W-1000, 5W-30, 5W-40, 10W-30.
Yog tias KA20DE ua tsis tiav, koj tuaj yeem hloov kho mus rau 2.0-liter NP300 nrog 114 hp, tsim los ntawm 2008 mus rau niaj hnub no.
