Nissan KA20DE injini
Injini ya petulo ya KA20DE yokhala ndi mutu wa silinda yamapasa awiri idawonekera mu 1991 ngati m'malo mwa 2,0-lita Z20 (OHC NA20S mum'badwo wachiwiri wa Nissan Atlas). Poyendetsa galimoto yake yogawa gasi (nthawi), unyolo umagwiritsidwa ntchito (makina a unyolo, omwe amasiyanitsidwa ndi kukana kuvala, kugwira ntchito mwakachetechete, kukana kusintha kwadzidzidzi kwa kutentha, mosakayika kumakhala kodalirika kuposa malamba a mano a mphira).
m'malo ake ndi zochitika osowa, zimachitika makamaka pambuyo kuthamanga makilomita oposa 300 zikwi (ndi bwino kuchita mayeso zodzitetezera pambuyo 100 zikwi Km). Kuvala kwakukulu kumawonekera mu mawonekedwe a:
- phokoso lalikulu,
- tensioner ndodo potulukira
- kusintha kwa nthawi ya valve chifukwa cha kudumpha kwa unyolo ndi mano 1 - 2 (okhazikitsidwa ndi diagnostics pakompyuta).
Kusintha kwa unyolo kuyenera kutsatiridwa motsatira kufananiza kwanthawi yayitali (kuyika ndi zikwangwani pamakina a unyolo kutsika poyerekeza ndi magiya a crankshaft ndi ma camshafts angayambitse kulephera kwa injini yamagalimoto).
Kulemba
Dzina la KA20DE limayimira:
KA - Mndandanda wa injini (kuchokera pa mzere wa 4-silinda gawo),
20 - Voliyumu (2,0 malita),
D - Injini yokhala ndi ma camshaft awiri apamwamba (DOCH),
E - jakisoni wamafuta amagetsi.
Mndandanda wa Nissan KA ukuimiridwa ndi mayunitsi a KA20DE, KA24E ndi KA24DE. Kumbali yabwino, imadziwika ndi kuphweka, kudalirika, kulimba, kumbali yolakwika - kugwiritsira ntchito mafuta ambiri (kwa KA20DE, 100 - 12 malita a petulo amawotchedwa pa 15 km mumayendedwe a mzinda, 8 - 9 malita mumsewu waukulu. mode, mu osakaniza (10/15) - 10,5 l) ndi zovuta kukonza ndi kukonza (makamaka poyerekeza ndi Toyota), kugwirizana ndi wandiweyani "kulongedza" mfundo pansi pa nyumba.
Nzeru yamagalimoto imanena za kudalirika kwakukulu ndi kulimba kwa injini - sikunali kotheka kupeza deta ya fakitale, muzochita, mwachitsanzo, kwa Nissan Caravan, makilomita oposa 300 (malingana ndi ikukonzekera, omwe amachotsa pafupifupi 200). hp kuchokera kumawilo, - kuyika ma intake manifold, ma throttle dampers, camshafts okhala ndi akasupe, ma cylinder head porting, ma pistoni opepuka opepuka okwera (~ 11) ndi ndodo zolumikizira, majekeseni ... - amapitilira 350 km zikwi).
Mulingo wa injini malinga ndi drive2.ru ndi 4+.
Magalimoto okhala ndi injini ya KA20DE
Injini yoyatsira mkati (ICE) KA20DE idayikidwa pazitsanzo zotsatirazi za Nissan (chiwerengerocho chimakhomeredwa kuchokera kumbali ya utsi wambiri pamphambano ya injini ndi gearbox):

Magalimoto onse omwe adatchulidwa amakhala ndi zinthu zowononga kwambiri pamagetsi otulutsa mpweya - injini ili ndi dongosolo la LEV (E-LEV index - zotulutsa ndi 50% zoyera kuposa 2000, 2005). Chigawochi chimayenda pa chisakanizo cha mpweya ndi petulo ndi chiŵerengero cha 40: 1.
Zolemba zamakono
Zigawo zazikulu zaukadaulo zaperekedwa patebulo:
| Dzina | mtengo |
|---|---|
| Mutu wa silinda | DOHC, 4 masilindala |
| Cylinder chipika zakuthupi | chitsulo choponyedwa |
