Uyini umehluko phakathi kwe-8 valve kanye ne-16 valve car engine?
Sezikhona izinjini ezifana neHonda V-Tec enamavalvu angu-16 futhi ezenza sengathi zinama-valve angu-8 uma kudingeka.
Amavalvu enjini anesibopho sokulawula ukungena nokuphuma kwamagesi kusilinda. (noma amasilinda) enjini, umsebenzi wayo oyinhloko ukuthungela ingxube phakathi komoya nophethiloli.
Eminyakeni ethile edlule izinjini ezijwayelekile zazifika namavalvu angu-8 kuphelayebo, amabili kusilinda ngasinye. Ngokuhamba kwesikhathi, abanye abakhiqizi bezimoto basebenzise izinjini ezinama-valve angu-16, ezine kusilinda ngasinye.
Sibona 1Ama-valve angu-6 enjinini eyodwa ayesho ukuphumelela, ngoba abakhiqizi babenomthwalo wemfanelo wokukhangisa izimoto zabo ezinama-valve angu-16 kabanzi.
Nokho, abaningi bethu abazi ukuthi lokhu kungcono noma kubi. Yingakho lapha sikutshela umehluko phakathi kwenjini yemoto eyi-8-valve ne-16-valve.
Lawa ma-motor anokuziphatha okuhlukile ngenxa yokuziphatha kwamagesi njengoba edlula emhubheni.
Izici ezivame kakhulu zama-valve angu-16 yizi:
- Amandla amaningi aphezulu ngokususwa okufanayo, nakuba beyithola nge-rpm ephezulu.
- sebenzisa okuningi uphethiloli kune-8v
Izici ezivame kakhulu zama-valve angu-8 yizi:
- Yiba ne-torque eyengeziwe phakathi nebanga
- Finyelela ngaphansi kwamandla aphezulu
– Ukunciphisa ukusetshenziswa kukaphethiloli
Izinjini ezinama-valve angu-16 zivame ukuba namandla kakhulu kunezinjini ezinama-valve angu-8 lapho zigijima phezulu ngenxa yokuthi ngokuba nama-valve amabili okukhipha umoya, umoya ungena ngesivinini esisheshayo namandla amancane kunalawo angathathwa i-piston kunama-valve angu-8.
Kodwa-ke, ngesivinini esiphansi, leli zinga eliphakeme lokungenisa umoya liyalahleka ku-valve engu-16, futhi i-valve engu-8 enabo ikhiqiza amandla angaphezu kwe-16-valve. Njengamanje, amasistimu wesikhathi ama-valve aguquguqukayo afana nesistimu ye-v-tec yakwaHonda avumela izinjini ezinama-valve angu-16 ukuthi ziziphathe njengezinjini ezingama-valve angu-8 kuma-low rev, zisebenzisa ama-valve amabili kuphela isilinda e) esikhundleni samane, kodwa njengoba ama-rev awo ekhulisa amanye ama-valve amabili avuleka. . ukusebenza okungcono.
ayini amasilinda
amasilinda Ziwumzimba i-piston ehamba ngawo.. Igama layo livela ekubunjweni kwayo, cishe, isilinda sejometri.
Ezinjinini zezimoto, amasilinda atholakala ngobuhlakani kanye nama-pistons, ama-valve, izindandatho, nezinye izindlela zokulawula nezokudlulisa, njengoba kulapho kuqhuma khona uphethiloli.
Amandla emishini enjini akhiwa ku-cylinder, bese iguqulwa ibe ukunyakaza kwemoto.
