Ngokuqinisekile abangaphezu koyedwa bakhumbula ama-80s nama-90s, lapho izinhlobo eziningi ziqala ukwethula amamodeli "16v” njengophawu lwemidlalo. Izimoto ezifana neRenault Clio 16v, iCitroën ZX 16v noma i-Opel Astra GSI 16v zigcwalise izingqwembe zokukhangisa, zikhombisa amandla nokusebenza kwazo.
Ngempela, ngaleso sikhathi kwakungahlukaniswa izinhlobo ezimbili zezinjini ezine-cylinder: i8v kanye ne16v. Okusho ukuthi, izinjini ezinama-valve angu-8, ezazinama-valve amabili isilinda; kanye nezinjini ezinama-valve angu-16, ezazinamavalvu amane isilinda. ngamunye neyakhe izinzuzo nezinkinga ukuthi nanamuhla ziyaqhubeka nokuvusa ilukuluku labantu abaningi.
Yini engcono i-8v noma i-16v?
Zombili izinjini zine-a ukuziphatha okuhluke kakhulu, okubangelwa ikakhulukazi ukuziphatha kwamagesi adlula epayipini. Izinjini 16v zibonakala ngokuthi:
- amandla amaningi aphezulu ngokufanayo i-cilindra, ngisho noma beyithola ngesivinini esiphezulu.
- dla okunye uphethiloli kune-8v
Imoto 8v esikhundleni salokho ibonakala ngokuthi:
- unayo i-torque eyengeziwe ebangeni eliphakathi
- finyelela amandla amancane aphezulu
- dla kancane
Lezi zici zibhekisela ezinjinini eziyi-16v kanye ne-8v yangaleso sikhathi. Ngentuthuko yamanje, njenge- electronics eziphambili noma i ukusatshalaliswa okuguquguqukayo, ama-motor angu-16v akwazile ukunqoba izithiyo zawo futhi anqoba i-8v kumamodeli amaningi. Ngakolunye uhlangothi, kukhona namamotho athile ayi-8v okuthi, ngobuchwepheshe bamanje, akwazi ukusebenza ngokuqhathaniswa ngokuphelele ne-16v. Njengoba kwenzeka kwiPeugeot 207 1.6 HDi FAP 8v yeqembu lePSA elimemezele i-112 CV, kwathi umfowabo ona-16-valve wafinyelela ku-109 CV.
Kodwa-ke, umuntu uyazibuza ukuthi kungani zombili izinjini zinalezi umehluko ophawulekayo onjalo ngokuba nama-valve angu-2 noma angu-4 isilinda ngasinye, uma amasistimu amanje esuswa ukuze kuthuthukiswe ukuziphatha kwawo. Ngaphezu kwakho konke, uma kungenjalo, abanawo umehluko omningi wesakhiwo noma wokuklama.
Kungani i-8v ne-16v inamakhono ahlukene?
Ama-rev aphezulu ku-16v
A ama-revs aphezulu, izinjini ze 16v banayo a ukugcwaliswa okungcono nokuthululwa kwegumbi elivuthayo, njengoba ama-valve athatha indawo enkulu ukuze amagesi adlule. Ngenxa yalesi sizathu, nakuba kulezi zimo isikhathi lapho ama-valve ehlala evulekile sincane, umoya ungena kalula kusilinda.
Lesi sici sithandwa yisu elephula kancane i- umjikelezo wetiyori wenjini enemivimbo emine: ukugcina ama-valve okungenisa evulekile lapho i-piston isivele ikhuphuka. Nakuba i-piston isivele iphusha umoya phezulu, isilinda siyaqhubeka sigcwala ngoba umthambo wegesi inamandla kakhulu ngesivinini senjini edonsa kanzima. Lo mthambo wegesi into efana ne-inertia ebamba umoya ngenxa yejubane layo. Isivinini esiningi, inertia eyengeziwe.
ama-rev aphansi enjini engu-8v
Yilokhu kanye okubangela I-Achilles isithende senjini engu-16v. Njengoba ijubane legesi liphansi ngesivinini esiyingxenye, uma ama-valve okungena ashiywe evulekile lapho i-piston ikhuphuka, umfudlana wegesi awunayo inertia eyanele yokunqoba umoya iphiston eliya phezulu. Ngakho-ke enye ingxube izophonswa ngaphandle, ilahlekelwe i-torque phakathi nenqubo.
Yilapho lapho ama-motor angu-8v akhipha izifuba zawo ngaphambi kwe-16v. Njengoba zine-valve eyodwa kuphela yokungenisa isilinda, zinendawo encane yokugcwalisa nokukhipha, futhi njengoba imithetho ye-fluid dynamics ibonisa: indawo encane yokudlula, igesi ifinyelela ngokushesha. Ngakho-ke, umoya ufinyelela isivinini esiphezulu ukuze ugcwalise igumbi elivuthayo futhi umfudlana wegesi une-inertia eyanele ebangeni eliphakathi ukuze unqobe umoya okhuphuka uphushwa ipiston. Yiqiniso, esimweni esishiwo ngenhla sokushiya i-valve yokudonsa ivuliwe lapho i-piston ikhuphuka.
Isikhathi se-valve esiguquguqukayo ukuze uthole izinzuzo zakho kokubili
Ukuze ube nezinzuzo zezinhlobo ezimbili zama-motor, kunezinhlelo ezihlukahlukene ezifana ne ukusatshalaliswa okuguquguqukayo. Ngalesi simiso sokusabalalisa, isikhathi sokuvula nokuvala ama-valve okungena kanye nokukhipha siyashintshwa. Isibonelo salezi zinjini sitholakala kwaHonda, ehlomisa izimoto zayo ezimbalwa ngezinjini ezishintshashintsha izikhathi (v-tec) noma injini. INNengine eklanywe ngabaseSpain.
Njengoba igama layo libonisa, kuwuhlelo ukuthi lungisa isikhathi senjini njengoba kudingeka. Ivumela ukuthuthukiswa noma ukubambezela ukuvulwa kwama-valve noma ngisho nokwandisa isikhathi avuliwe. Ngale ndlela bafinyelela ukugcwaliswa okuhle kwegumbi lomlilo, kokubili ekuguqukeni okuphansi nokuphezulu. Kuvidiyo elandelayo ungabona ukuthi lesi simiso siquketheni, okuye kwasho intuthuko enkulu ekusebenzeni kahle nokusebenza kwezinjini:
Izithombe 3 no-6 - Mic noScott Murray
I-vtec noma i-i-vtec iyohlala iyisizathu sokuthi kungani lezo zimoto ziguquleka kakhulu
futhi ngaphandle kwesivinini esisebenzayo!
Uma ekusebenzeni bavame ukudla okuningi, ngaphezu kwalokho, ukuze babe namandla kakhulu ngoba umbuso wabo wenguquko uyakuvumela futhi unikeze isivinini esikhulu nakuba kunqunyelwe izilinganiso zethrafikhi, kungani manje bathola i-16V engaphezu kwe-8V?
Ngokubona kwami, ukuze izimoto ezihamba phakathi zibe namandla nesivinini engeziwe futhi izilima ezingelutho zizibulale kalula emgwaqeni ongemuhle wezwe.
Ngincamela i-8v Xq motor bavame ukusetshenziswa kakhulu futhi impilo yabo ayifushane njenge-16v
Sanibonani iloli lami yipeugeot partner hdi 1.6 enamavalve angu 16 ngicela ukwazi ukuthi ingashintshwa yini ifane nenjini kodwa enamavalve awu 8 since ngithole enye yalezo mpawu futhi eyami ayisangisebenzeli.
unayo iyathengiswa i-hdi 16 v ngithola ucingo lwami 2214110471
Ngokwalokhu engikufundile, i-16v iyi-crap… Injini iyavilapha ngesikhathi sokusetshenziswa OKUJWAYELEKILE, futhi ngaphezu kwalokho idla kakhulu.
Okuwukuphela kwenzuzo amandla engeziwe kuma-revs aphezulu, sizobona kuphela lawo mandla "ngokuhlola" injini.
Empeleni, injini ihlale ilethwa kuma-revs amaphakathi, noma aphansi - uma amandla edingeka ngokuzumayo, lawo mandla awekho enjinini engu-16v, kuyilapho i-8v izonikeza amandla engeziwe.
I-16v…ibiza kakhulu, ayisebenzi kahle, iphila isikhathi esifushane futhi inamandla amancane ekusetshenzisweni kwansuku zonke.
Awekho ama-motor angu-4v?
Inani lama-valve kufanele lihambisane nenani lamasilinda enjini. Isilinda ngasinye kufanele okungenani sibe nevalvu yokungenisa engu-1 (okungena ngayo ingxube yamafutha omoya) kanye nevalvu yokukhipha umoya engu-1 (okuphuma ngayo amagesi asele). Sesikushilo lokho, azikho izinjini ezingama-4-cylinder, 4-valve.
Uma kukhona 2-cylinder (two-cylinder) 4-valve izinjini (amavalvu amabili isilinda). Kujwayelekile ukubabona ezithuthuthu nama-ATV, futhi mancane amathuba okuba ubathole ezimotweni.
Angiqondi ukuthi abakhiqizi bezimoto, cishe bonke, benza kanjani izinjini zabo ezinama-valve angu-16 4 isilinda, ukube bekungekuhle bebezokhipha u-8 nangaphansi kwezindleko. Izimoto ezinezinjini ezingama-valve angu-8 zithunyelwa ukuyolanda.
Ngishayela i-sentra yango-1997 16v, futhi inhle kakhulu emandleni amafushane namade.
Futhi ekugcineni, iyiphi engcono kakhulu? 8 amavalvu noma 16 valve? Onolwazi ngicela aphendule. Ngiyabonga!
Umqondo wami ukuthi i-16v iyindlela engcono kakhulu, ukusetshenziswa kuncane uma kuqhathaniswa ne-8v futhi uma uhamba ubona umehluko, ngihamba njalo ngakho ngithanda amandla.
Injini enama-valve angu-8 ingcono... Uma uyishuna kahle, iqhumisa umsele kwezinye izimoto hahahaha
Ukubingelela kusuka eChile
PS: Imoto yami yake yasika ibhande le-timing belt, akwenzekanga lutho enjinini
XD
Ngashintsha ibhande ngaqhubeka.
USEKELA 8V IZINJINI
Sanibonani Madoda. Kokuhlangenwe nakho kwenu koku-ayina, umbuzo, ingabe kungenzeka ukulungisa noma ukulungisa ikhanda lesilinda elingu-16v libe injini yoqobo engu-8V??? nge-double carburation system. ngiyabonga slds
Yebo Gerardo, ungakwazi.
E-Uruguay nase-Argentina amakhava e-AP motor ayashintshwa ukusuka ku-8v kuya ku-16v. Baphinde bafakwe amakepisi angu-20v alethwa amanye ama-Audi, afana neBora noma iJetta.
Ukubingelela
Ekugcineni izimoto zinhle uma uzisebenzisa ngokwezidingo zakho unganikezi iToyota noma iHyundai umshayeli wenqola noma umshayeli we-trailer, futhi kancane kumshayeli kagandaganda bazokutshela lokho. abayithandi.
