Tiyimbireni Masiku Ano!

Kodi Ubwino Wosintha Ma Valve Timing System Ndi uti?

Chiyambire kubwera kwa injini, anthu sanasiye kumusintha, ndipo tawonanso mibadwo ya injini zatsopano zosunthika zosiyanasiyana kuyambira zazikulu mpaka zazing'ono. Chifukwa cha kuchuluka kwa magalimoto, tinayambitsa vuto lamagetsi. , Mafuta, gwero losasinthika, amatopa pang'onopang'ono ndikufukula kwathu kwatsiku ndi tsiku. Monga anthu amakono, sitimaganizira zamagetsi kapena zosungira zina m'badwo wotsatira. Ndi kuyesayesa kwathu kwa uinjiniya, tapanga injini yatsopano yopulumutsa mphamvu ndipo tabweretsa ukadaulo wopulumutsa mafuta. Lero wogulitsa injini yamagalimoto adzagawana nanu maubwino amachitidwe osintha nthawi yama valve.

 

Kuphatikiza pa fulumizitsa ndi chopangira mphamvu (kapena kuwonjezeka kwamakina), zinthu zomwe zimakhudza mpweya wamphamvu ndizophatikizira mavavu.

Nthawi zambiri, valavu yosinthika imaphatikizapo mitundu ingapo yamitundu yosiyanasiyana: nthawi yosinthira mbali yodyera, kukweza kosunthika mbali yodyera, nthawi yosinthira mbali yotulutsa utsi, ndi kukweza kosunthika mbali yakutulutsa. Ma injini ena ali ndi imodzi yokha, ndipo injini zina zimakhala ndi zingapo nthawi imodzi. Chifukwa chake, ukadaulo wa "kudya mosiyanasiyana" kwama injini osiyanasiyana sikuti chimodzimodzi pamalingaliro.

Mfundo yosinthira nthawi yamagetsi

Mfundo yogwirira ntchito injini yamafuta anayi yomwe timadziwa. Mikwingwirima inayi yogwira ntchito yokoka, kukakamiza, kugwira ntchito, kutopetsa, komanso kupitiliza kwa ntchito kwa injini zimakhudza nthawi yoyamba ndi yomaliza ya fulumizidwe. Aliyense amadziwa kuti valavu imayendetsedwa ndi crankshaft ya injini kudzera pa camshaft, ndipo nthawi ya valavu imadalira mawonekedwe ozungulira a camshaft. Pa injini wamba, nthawi yotsegulira ndi kutseka kwa valavu yolowera ndi valavu yotulutsa imakhazikika. Kusintha kwa nthawi kovuta kumeneku ndikovuta kuzindikiritsa zofunikira za injini pamawiro osiyana. Tikufuna kupanga injini kuti ichite bwino kwambiri Kawirikawiri timasintha mbali ya camshaft kuti tisinthe nthawi yotsegulira ndi kutsekera kwa fulumizitsa kuti tikwaniritse nthawi yantchito yachangu kuti tipeze mphamvu yayikulu kwambiri. Tsopano tili ndi nthawi yamagetsi yosinthira kuti tithetse izi mosavuta. Ukadaulo.

Ukadaulo wosintha wa valavu ndi mawonekedwe osavuta komanso makina otsika mtengo muukadaulo wonse wama valve wosintha. Imagwiritsa ntchito ma hayidiroliki ndi zida zamagalimoto zosinthira nthawi yayitali malinga ndi zosowa za injini. Kusintha kwakanthawi kwa valavu sikungasinthe nthawi yotsegulira valavu, koma kumangoyendetsa nthawi yotsegulira kapena kutseka valavu pasadakhale. Nthawi yomweyo, imatha kuyendetsa sitiroko yotsegulira valavu ngati camshaft yosintha, motero imakhudza pang'ono magwiridwe antchito a injini.

 

Ponena za nthawi yamagetsi yosinthika, injini ya HONDA ili ndi chitsogozo china. Injini ikuyenda movutikira, pisitoni yaying'ono ili pamalo oyamba, ndipo manja atatu amiyala amagawanika. Kamera yayikulu ndi yachiwiriyo imakankhira dzanja lamwala lachiwiri ndi lachiwiri. Sinthani kutsegulidwa ndi kutsekedwa kwamavavu awiri olowera, valavu yonyamula ndi yocheperako, zinthu zili ngati injini wamba. Ngakhale kamera yapakatikati imakankhiranso dzanja lamiyala yapakatikati, chifukwa mikono yamiyalayo imagawanika, manja enanso awiriwo samayang'aniridwa ndi iwo, kotero kutsegula ndi kutseka kwa valavu sikukhudzidwa.

 

Koma injini ikafika pamiyeso yayikulu (mwachitsanzo, galimoto yamagalimoto ya Honda S2000 ikafika 5500 rpm pa 3500 rpm), kompyutayo imalangiza valavu ya solenoid kuti ipatse ma hydraulic system ndikukankhira pisitoni yaying'ono m'manja pangani zida zitatu zogwiritsa ntchito rocker zokhoma kukhala thupi limodzi ndipo zimayendetsedwa ndi cam yapakati limodzi. Popeza kamera yapakati ndiyokwera kuposa ma cam ena ndipo imakweza kwambiri. Zida zamagalimoto zamagalimoto Kutalika komanso kukweza kumakulanso. Liwiro la injini likamatsikira pamiyeso yochepa, kuthamanga kwa ma rocker m'manja kumacheperanso, pisitoni imabwerera pamalo ake oyambilira kasupe wobwerera, ndipo mikono itatu yonyamula imasiyana.

 

Mwanjira imeneyi, mutha kuyendetsa mafuta anu pang'onopang'ono, ndipo nthawi yomweyo mukwaniritse zosowa zanu pakuwonjezera mphamvu injini ikamathamanga kwambiri. Dongosolo lonse la VTEC limayang'aniridwa ndi main computer engine (ECU). ECU imalandira ndikusintha magawo amagetsi a injini (kuphatikiza kuthamanga, kuthamanga, kuthamanga kwa galimoto, kutentha kwa madzi, ndi zina zambiri), zotulutsa zogwirizana ndi kayendetsedwe kake, ndikusintha rocker piston hydraulic system kudzera pamagetsi a solenoid Kuti injini iziyendetsedwa ndi makamu osiyanasiyana mosiyanasiyana, omwe amakhudza kutsegula ndi nthawi ya valavu yolowera. Kuti mupange mphamvu zomwe mumayembekezera kuti mupeze.
