Valve ya PCV ku modoka ni iki?
Valve ya PCV (Crankcase forced ventilation valve) ni igice cy'ingenzi cya moteri y'imodoka. Inshingano yayo nyamukuru ni ukuyobora uruvange ruri muri crankcase mu gice cy'ingufu kugira ngo rwongere gushya, birinde ko umwuka usohoka mu kirere kandi bigatera umwanda. Ariko kandi, irinda kwangirika kwa peteroli ya moteri no kwangirika kwa moteri.
Imiterere n'amahame ngenderwaho y'imikorere
Valve ya PCV igizwe n'umubiri wa valve, valve, igipfundikizo cya valve n'isoko, kandi urugero rwo kuyifungura no kuyifunga rugengwa n'urugero rw'ingufu za vumbi rya intake manifold. Iyo moteri ikora ku muvuduko muto cyangwa idakora, umubiri wa valve uba ufunguye gato kugira ngo ushyiremo uruvange ruto. Ifunguye neza ku muvuduko mwinshi cyangwa mu gihe cyo kwihutisha kugira ngo yongere ingano y'umwuka. Iyo moteri igarutse, umubiri wa valve wifunga byikora kugira ngo wirinde ko crankcase iturika.
Imirimo y'ingenzi
Kurengera ibidukikije bya Youdaoplaceholder0: Kurinda ko imyuka ivanze idatwitswe isukurwa mu kirere mu buryo butaziguye kugira ngo hirindwe umwanda.
Youdaoplaceholder0 Rinda amavuta ya moteri : Irinde ko umwuka uva mu mazi ugabanya amavuta no kwangirika, bityo wongere igihe cyo kubaho kwa moteri.
Youdaoplaceholder0 Kugenzura umuvuduko: Kuringaniza umuvuduko wa crankcase kugira ngo wirinde ko amavuta asohoka.
Iyo valve ya PCV izibye, ishobora kwanduza icyuma gikoresha lisansi, ikoreshwa ryiyongera, moteri irangirika vuba cyangwa ikangirika. Ni ngombwa gusukura buri gihe imyanda iyikikije (urugero nko kugenzura ko umubiri w’icyuma ugenda neza no gukurura umwuka mu gihe cyo kuyitunganya buri gihe).
PCV ni incamake y'amagambo atatu "Positive Crankcase Ventilation" mu Cyongereza. Mu Gishinwa, bivuze sisitemu yo kugenzura ingaruka z'ibyuka bihumanya ikirere (cyangwa isafuriya y'amavuta). Valve ya PCV igizwe n'umubiri wa valve, valve, igifuniko cya valve n'isoko, kandi ntishobora gusenywa. Inshingano yayo nyamukuru ni: kwinjiza gazi iri muri crankcase mu gikoresho cyo kwinjiramo binyuze muri valve ya PCV, kandi umwuka muto winjira mu buryo butaziguye muri filter y'umwuka iturutse kuri valve ya PCV. Ibi birinda ibintu nk'irema ry'urubura ku mugozi, umuriro utuzuye, no kwangirika kw'ibyuka bihumanya. Bikumira gazi kwinjira mu kirere kandi icyarimwe bikumira amavuta ya moteri kwangirika.
Mu mpera z'igikorwa cyo gutwika moteri, hari uruvange rutarashya rwinjira mu mashini isohoka mu mpande za piston bitewe n'umuvuduko mwinshi. Ubwo bwoko bw'amazi bwitwa "blow-by" mu nganda. Iyi myuka isohoka mu mashini isohoka mu mashini ijya mu kirere, bigatera umwanda. Iyo uruvange rwinjiyemo rudasohotse, ruzanagabanya amavuta ya moteri mu mashini, bigatuma amavuta yangirika kandi bigatuma ibice bya moteri byangirika vuba. Kuva mu myaka ya 1960, muri leta ya California muri Leta Zunze Ubumwe za Amerika niho habaye iya mbere mu gusaba ko imodoka zigira sisitemu za PCV, zabaye ikintu cy'ingenzi mu modoka.
Moteri nyinshi za lisansi zifite valve za PCV (ibikoresho byo guhumeka bishorwamo umwuka) kugira ngo byorohereze ihererekanya ry'umwuka muri moteri. Ariko, imyanda iri mu mpande ishobora kwirundanya hafi ya valve za PCV, bigatuma zifunga. Iyo valve ya PCV izibye, gazi yanduye isubira mu yungurura ry'umwuka, ihumanya icyuma gifunguza, ikagabanya ubushobozi bwo kuyungurura, bigatuma lisansi ikoreshwa cyane, moteri ikaranduka cyane, ndetse na moteri ikangirika. Kubwibyo, ni ngombwa kubungabunga PCV buri gihe no gukuraho imyanda hafi ya valve ya PCV.
Valve ya PCV ni valve igenzura ingano y'umwuka. Ishyirwa hagati ya sisitemu yo guhumeka ya crankcase na sisitemu yo kwinjira ya moteri. Valve ya PCV igenzurwa n'urwego rw'ingufu kugira ngo igenzure urujya n'uruza rw'umwuka uturuka kuri sisitemu yo guhumeka ya crankcase yinjira muri sisitemu yo kwinjiramo. Iyo moteri ikora ku muvuduko mwinshi, umuvuduko wayo ugomba kuba munini kuruta iyo ikora ku muvuduko muto. Muri icyo gihe, iyo moteri igize ikibazo cyo gushya, valve ya PCV igomba kuba ishobora guhagarika umuvuduko kugira ngo crankcase iturikizwe.
Buri modoka ifite umuyoboro w'imyotsi usohora umwuka uva muri moteri ujya hanze y'imodoka. Ariko, ntibishoboka gukuramo umwuka wose uva muri iyo modoka burundu. Ingufu nke zicana zizakomeza kwinjira mu isafuriya y'amavuta binyuze mu cyuho kiri hagati ya piston n'urukuta rwa silindiri. Iyo amavuta na gazi byinjira mu isafuriya y'amavuta byirundanyije kandi ntibishobore gusohoka, bizatera umwuka ushyushye, ugabanya amavuta ya moteri gusa ahubwo unatera amavuta mabi ku bice bya moteri. Bizanatera ingaruka zikomeye nko gukoresha amavuta ya moteri mu buryo budasanzwe. Kubwibyo, amavuta na gazi biri mu isafuriya y'amavuta bigomba kuba bifite umuyoboro usohora umwuka. Mu bihe byashize, mbere y'uko habaho amategeko n'igenzura ry'umwanda w'imyotsi iva mu modoka, umuyoboro wahuzwaga n'isafuriya y'amavuta kugira ngo usuke amavuta na gazi mu kirere mu buryo butaziguye. Uko imodoka igenda ishaje, niko amavuta na gazi biva mu isafuriya birushaho kuba bibi, kandi niko umwuka usohoka mu isafuriya y'amavuta urushaho gusohoka, bigatera umwanda ukomeye w'umwuka.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
