Waa maxay macnaha "dual camera"?
Suuqgeyntu waa qayb muhiim ah oo ka mid ah iibinta baabuurta. Haddi ay xayeysiiso Chevrolet block weyn V8 sida "matoorka jiirka" ama "lix-dhululubo Hemi", macaamiishu waxay inta badan soo jiitaan badeecooyinka baabuurta ama qaybaha leh magac sumad hal abuur leh halkii ay ka heli lahaayeen faa'iidooyin alaabeed gaar ah. Mid ka mid ah naanaysyada sida caadiga ah loo fahmaa waa qaabaynta mishiinka kamaradaha mataanaha ah. In kasta oo ay ku sii badanayaan baabuurta casriga ah iyo kuwa xamuulka qaada, macaamiil badan ayaan wax fikrad ah ka lahayn macnaha dhabta ah iyo waxa loo isticmaalo.
Hoos waxaa ku taxan xaqiiqooyin ku saabsan waxa uu yahay mishiinka kamaradaha mataanaha ah, sida uu u shaqeeyo, iyo faa'iidooyinka ku jira in lagu isticmaalo baabuurta casriga ah, kuwa xamuulka ah, iyo matoorada SUV.
Qeexida Habaynta Labada Kamara
Matoorka gubashada gudaha ee piston-ka ee dhaqameedku wuxuu leeyahay hal-shaft kaxeeya bistoonada iyo isku xirka ulaha ay ku xiran tahay silsilad ilaa hal shaabad oo fur oo xirta qalabka qaadashada iyo qiiqa qiiqa inta lagu jiro habka afar-stroke. Shaadhka kambuyuutarku qasab maaha inuu ka sarreeyo dhululubada ama u dhow valves laftooda, iyo tuubooyinka ayaa loo isticmaalaa in lagu furo oo la xidho valves.
Matoorka kamarad mataanaha ah waxa uu leeyahay laba kamarado, gaar ahaan laba-camshaft-ka-sare ama DOHC, kaas oo go'aamiya goobta tareenka valve. In kasta oo ay u muuqato mid qabow in la yiraahdo waxaad leedahay mashiinka kamarad mataanaha ah, had iyo jeer maaha ereyga saxda ah.
Matoorka laba-cammuudka ah, laba xabbo oo kamarad ah ayaa ku yaal gudaha madaxa dhululubada, oo ku yaal korka dhululubada. Mid ka mid ah camshaft-ka ayaa koontaroolaya valves-ka qaadashada kan kalena wuxuu maamulaa valves qiiqa. Matoorka DOHC wuxuu leeyahay sifooyin dhowr ah oo u gaar ah naqshadiisa. Tusaale ahaan, gacmaha dhagaxa ayaa ka yar ama waxaa laga yaabaa in ay maqan yihiin. Xaglo ballaadhan ayaa lagu arkaa inta u dhaxaysa labada nooc ee valves marka loo eego hal shaabad sare ama SOHC.
Matoorro badan oo DOHC ah ayaa ku leh halbeegyo kala duwan oo ku yaal dhululubo kasta, in kasta oo tan aan looga baahnayn in mishiinku shaqeeyo. Aragti ahaan, valves badan halkii dhululubo ayaa hagaajiya awoodda injiinka iyada oo aan la kordhin socodka hawada. Ficil ahaan, tani mar walba run maaha. Waxay runtii kuxirantahay qaabeynta mishiinka haddii nooca rakibaadda madaxa dhululubada ay faa'iido yeelan doonto.
Faa'iidooyinka Dual Camera
Farsamoyaqaannada xirfadleyda ahi waxay isku raaceen in habka ugu wanaagsan ee lagu wanaajin karo waxqabadka matoorka ay tahay in la hubiyo socodka hawada wanaagsan ee madaxyada dhululubada. In kasta oo dukaamada mishiinada intooda badani ay tan ku gaadhaan iyaga oo balaadhinaya qaadashada iyo tuubooyinka qiiqa, manifolds, iyo raritaanka iyo nadiifinta qolalka si ay u socdaan siman, soosaarayaasha baabuurtu waxay qaateen qaabeynta multi-valve-per-cylinder. Naqshadeynta DOHC waxay u oggolaaneysaa socodka hawada xaddidan oo yar oo xawaare sare leh. Haddii matoorku uu sidoo kale leeyahay nashqad dhowr-valve ah, waxa kale oo uu hagaajiyay gubashada si waxtarkeedu u fiicnaado sababtoo ah meelaynta balaastigga.
Sababtoo ah DOHC ama mishiinnada kamaradaha mataanaha ah ayaa hagaajiyay socodka hawada ee dhululubada, inta badan marka la barbardhigo way ka xoog badan yihiin waxayna bixiyaan dardargelin wanaagsan. Waxa kale oo ay wanaajin karaan hufnaanta, taas oo macnaheedu yahay in lacag lagu badbaadiyo saldhigga shidaalka. Intaa waxaa dheer, matoorada DOHC waxay u janjeeraan inay si aamusan oo siman u shaqeeyaan. Maanta, mishiinada kamaradaha mataanaha ah ayaa diyaar u ah gawaadhi kala duwan, laga bilaabo hatchbacks heerka gelitaanka ilaa baabuurta ciyaaraha kor u qaada.
