K20 - injini ya Honda. Mafotokozedwe ndi zovuta zofala kwambiri

Mphamvu yamagetsi idapangidwa kuyambira 2001 mpaka 2011. Iwo anaika pa zitsanzo kwambiri magalimoto a Mlengi Japanese, kuphatikizapo Accord ndi Civic. Mitundu ingapo yosinthidwa ya K20 idapangidwanso panthawi yopanga. Injini yamtunduwu wopanda zinsinsi m'nkhani yathu!

K20 - injini yogwira ntchito mwapadera

Kuyambitsidwa kwa injiniyo mu 2001 kunalimbikitsidwa ndi kusinthidwa kwa mayunitsi kuchokera ku banja la B. Chifukwa cha ndemanga zabwino kwambiri zomwe Baibulo lapitalo linalandira, panali kukayikira ngati Baibulo latsopanolo lidzakwaniritsa zomwe ankayembekezera. Komabe, manthawo anakhala opanda maziko. Kupanga K20 kunayenda bwino.

Kumayambiriro, K20 idayambitsidwa mumitundu ya 2002 RSX ndi Civic Si. Mbali yapadera ya njinga yamoto inali yakuti inali yoyenera kukwera kwamphamvu komanso kukwera mumzinda. 

Zipangizo zomwe zimagwiritsidwa ntchito pagalimoto

Kodi K20 inamangidwa bwanji? Injiniyo ili ndi valavu ya DOHC ndipo ma shafts odzigudubuza amagwiritsidwa ntchito pamutu wa silinda kuti achepetse kukangana. Kuphatikiza apo, njinga yamoto imagwiritsa ntchito makina oyatsira opanda coil-spark. Kukhazikika kwake kumatengera kuti spark plug iliyonse ili ndi koyilo yake.

Opanga injini sanasankhe njira wamba yotengera nthawi ya valve. M’malo mwake, anagwiritsa ntchito njira yoyendetsera nthawi yoyendetsedwa ndi kompyuta. Chifukwa cha ichi, zinakhala zotheka kulamulira magawo poyatsira ntchito ECU potengera zambiri masensa osiyanasiyana.

Zitsamba zachitsulo zoponyera ndi midadada zazifupi

Mfundo ina yofunika kuisamalira ndi yakuti ma silinda ali ndi zitsulo zotayira. Anali ndi makhalidwe ofanana ndi omwe amagwiritsidwa ntchito m'mabanja a B ndi F a njinga. Monga chidwi, masilindala FRM aikidwa mu H ndi F mndandanda powertrains kupezeka mu Honda S2000.

Pali njira zothetsera zomwe zili ndi zofanana ndi zomwe zili mu mndandanda wa B. Tikukamba za midadada iwiri yaifupi ya mapangidwe omwewo ndi kusiyana kwa sitimayo kutalika kwa 212 mm. Pankhani ya midadada K23 ndi K24, miyeso iyi imafika 231,5 mm.

Mitundu iwiri ya dongosolo la Honda i-Vtec

Pali mitundu iwiri ya dongosolo Honda i-Vtec mu K mndandanda. Atha kukhala ndi VTC yosinthira nthawi ya valve pa kamera yolowera, monga momwe zilili ndi mtundu wa K20A3. 

Momwe zimagwirira ntchito ndikuti pa low rpm ndi imodzi yokha ya mavavu olowera yomwe imatsegulidwa kwathunthu. Yachiwiri, mosiyana, imatsegula pang'ono chabe. Izi zimapanga kugwedezeka mu chipinda choyaka moto zomwe zimapangitsa kuti mafuta azikhala bwino komanso injini ikathamanga kwambiri ma valve onse amatseguka zomwe zimapangitsa kuti injini igwire bwino ntchito.

Kumbali ina, mumitundu ya K20A2 yomwe idayikidwa pamagalimoto a Acura RSX Type-S, VTEC imakhudza ma valve onse olowera komanso otulutsa. Pachifukwa ichi, ma valve onsewa amatha kugwiritsa ntchito makamera osiyanasiyana. 

Ma injini a K20C amagwiritsidwa ntchito mu motorsport.

Wabanja la K uyu amagwiritsidwa ntchito ndi magulu omwe akupikisana nawo mu F3 ndi F4. Kusiyana kwa mapangidwe ake ndikuti injini sizikhala ndi turbocharger. Chitsanzocho chinayamikiridwanso ndi madalaivala otchedwa. hot rodd ndi kit galimoto, chifukwa cha kuthekera koyikira galimotoyo pamakina oyendetsa magudumu akumbuyo.

K20A - data yaukadaulo

Injiniyo idapangidwa molingana ndi chiwembu chamu mzere anayi, pomwe ma cylinders anayi ali pamzere umodzi - motsatira crankshaft wamba. Voliyumu yonse yogwira ntchito ndi malita 2.0 pa 1 cu. masentimita, nayenso, m'mimba mwake ndi 998 mm ndi sitiroko 3 mm. M'mitundu ina, mapangidwe a DOHC amatha kusinthidwanso ndi ukadaulo wa i-VTEC.

Masewera a K20A - ndi osiyana bwanji?

Anagwiritsidwa ntchito mu Honda Civic RW, mtundu uwu wa unit umagwiritsa ntchito flywheel ya chrome-yokutidwa, komanso ndodo zolumikizira ndi mphamvu zochulukirapo. Ma pistoni oponderezedwa kwambiri ndi akasupe a valve olimba kwambiri adagwiritsidwanso ntchito.

Zonsezi zimathandizidwa ndi ma camshafts omwe amakhala nthawi yayitali. Anaganizanso kupukuta pamwamba pa madoko kudya ndi utsi wa yamphamvu mutu - izi zikugwira ntchito kwa zitsanzo kuyambira 2007 mpaka 2011, makamaka Honda NSX-R.

Kuyendetsa ntchito

Injini za banja la K20 nthawi zambiri sizimayambitsa mavuto akulu pantchito. Kuwonongeka kofala kwambiri kumaphatikizapo: kutayikira kwamafuta kosalamulirika kuchokera kutsogolo kwa crankshaft main oil seal, exhaust camshaft lobe chafing, komanso kugwedezeka kwakukulu kwa gawo loyendetsa.

Kodi Muyenera Kusankha Njinga Zamoto za K20? Injini yodziwika

Ngakhale pali zolakwika zomwe zanenedwa, njinga zamotozi zikadalipo m'misewu yathu. Izi zikhoza kuonedwa ngati umboni wa kudalirika kwawo. Choncho, K20 ndi injini ya Honda, Mulimonsemo, ngati akadali mu chikhalidwe chabwino luso, akhoza kusankha bwino.
