Kodi pali kusiyana kotani pakati pa 8 valve ndi 16 valve car engine?

Tsopano pali injini ngati Honda V-Tec kuti 16 mavavu ndi kuchita ngati 8 mavavu pakufunika.

Ma valve mu injini ali ndi udindo wowongolera kulowa ndi kutuluka kwa mpweya mu silinda. (kapena masilindala) a injini, ntchito yake yayikulu ndikuwotcha kusakaniza pakati pa mpweya ndi mafuta. 

Zaka zingapo zapitazo injini wamba anangobwera ndi 8 mavavuinde, awiri pa silinda iliyonse. M'kupita kwa nthawi, ena automakers akhazikitsa injini yokhala ndi mavavu 16, anayi pa silinda iliyonse. 

Tikuwona 1Mavavu 6 mu injini imodzi amatanthawuza kupambana, chifukwa opanga anali ndi udindo wokweza magalimoto awo a ma valve 16 ambiri.

Komabe, ambiri aife sitidziwa ngati izi ndi zabwino kapena zoipa. Ndicho chifukwa chake apa tikukuuzani kusiyana pakati pa 8 valve ndi 16 valve galimoto injini.

Ma motors amenewa ali ndi makhalidwe osiyanasiyana chifukwa cha khalidwe la mpweya pamene akudutsa mumsewu. 

Makhalidwe ambiri a injini 16-vavu ndi: 

- Mphamvu zambiri pachimake ndi kusamuka komweko, ngakhale amapeza pamakwerero apamwamba.

- kudya zambiri mafuta kuposa 8v

Makhalidwe ambiri a injini 8-vavu ndi: 

- Khalani ndi torque yambiri pakatikati

- Fikirani mphamvu zochepa kuposa mphamvu yayikulu

- Kuchepetsa kugwiritsa ntchito mafuta

 Ma injini a ma valve 16 amakhala amphamvu kwambiri kuposa ma valve 8 omwe amathamanga kwambiri chifukwa chokhala ndi ma valve awiri olowetsa mpweya, mpweya umalowa mofulumira komanso ndi mphamvu yochepa kuposa momwe piston ingatengere kusiyana ndi injini ya 8 valve.

Komabe, pa liwiro lotsika, mpweya wokwera kwambiri uwu umatayika mu valve 16, ndipo valve 8 yomwe ili nawo imapanga mphamvu zambiri kuposa 16 valve. Pakalipano, makina osinthira nthawi ya valve monga Honda's v-tec system amalola injini za 16-valve kukhala ngati injini za 8-valve pazitsulo zotsika, pogwiritsa ntchito ma valve awiri pa silinda e) m'malo mwa zinayi, koma pamene ma rev awo amawonjezera ma valve ena awiri otseguka. . kuti muchite bwino.

masilinda ndi chiyani

zonenepa Ndi thupi lomwe pisitoni imadutsamo.. Dzina lake limachokera ku mawonekedwe ake, kunena pang'ono, silinda ya geometric.

Mu injini zamagalimoto, ma cylinders amakhala mochenjera limodzi ndi pistoni, ma valve, mphete, ndi njira zina zowongolera ndi kufalitsa, popeza ndipamene kuphulika kwa mafuta kumachitika.

Mphamvu yamakina a injini imapangidwa mu silinda, yomwe imasinthidwa kukhala kayendedwe kagalimoto.
