Igipfukisho cya valve ni iki?
Igipfukisho cya valve ni icyuma gikingira camshaft kiri hejuru y'icyumba cya valve kandi kigakora umwobo ufunze neza ufite umutwe wa silinda (hari kandi inzira zo kugarura amavuta, inzira zo gutanga amavuta n'izindi nzira zo kugabanya amavuta zihujwe n'izindi myobo)
Ni iyihe mpamvu ituma umwuka usohoka mu gipfundikizo cya valve?
Gusohoka k'umwuka uva mu gipfundikizo cya valve bizatuma imodoka idashobora gutwara. Iyo uruvange rwuzuye cyane cyangwa ruto cyane, amavuta ari mu cyumba cyo gutwika ntabwo yashya burundu, bigatuma lisansi ikoreshwa cyane. Bizatuma kandi imodoka yihuta buhoro buhoro. Moteri iragora gutangira, ingufu ziragabanuka, umuriro ntuba wuzuye, carbon deposit iba ikomeye, ndetse na silindiri imwe ntizakora. Muri rusange, niba hari gusohoka kw'amavuta, ni byiza gusimbuza igipfundikizo cya valve.
Ese hari icyo bitwaye niba gasket y'umupfundikizo w'ingufu ivamo amavuta?
Agasanduku k'umupfundikizo w'ingufu kavamo amavuta, ibyo bikaba bikigira ingaruka ku modoka. Gakwiye gusimburwa ku gihe. Agasanduku k'umupfundikizo w'ingufu kakoreshwa cyane cyane mu gufunga kugira ngo hirindwe ko amavuta ava. Iyo kadasimbuwe ku gihe, agasanduku kazagabanuka, kagakomera, kagatakaza uburimbane ndetse kakanavunika cyane. Niba ari ukuva kw'amavuta guterwa no gusaza k'umutwe wa silinda ya valve, ikibazo gishobora gukemurwa no gusimbuza umutwe wa silinda ya valve undi mushya. Iyo uyiguze ubwawe, igiciro ni hafi yuan 100. Iyo ugiye mu iduka rya 4S kuyisimbuza, izaba nibura yuan 200. Gasket y'umupfundikizo w'ingufu muri rusange ikorwa muri rubber, kandi kimwe mu bintu by'ingenzi biranga rubber ni ugusaza. Kubwibyo, niba igihe imodoka imara ari kirekire cyane, ibikoresho bya rubber bizasaza kandi bikomere, bigatuma amavuta ava. Iyo usimbuwe, witondere ingingo zikurikira. Iyo usimbuwe, sukura neza ubuso bufatanye. Shyira kole niba bishoboka, kuko bifata igihe kirekire gushyira kole. Nta kibazo gukoresha kole. Biterwa n'ibyo nyir'imodoka yifuza. 2. Moteri igomba kuba ikonjeshejwe neza mbere yuko ihindurwa. 3. Mu gushyiramo umupfundikizo wa valve, komeza uyishyiremo inshuro nyinshi ukurikije umurongo. Nyuma yo gukosora screw, subira kuri screw igororotse. Ibi bizakurinda umuvuduko utaringaniye kuri gasket y'umupfundikizo wa valve.
Ni gute igipfukisho cya valve gisa nabi?
Muri rusange hari impamvu nyinshi zitera kwangirika kwa gasket y'umupfundikizo wa valve. Iya mbere ni uko bolt ifunguye, iya kabiri ni ukuguruka kwa moteri, iya gatatu ni ukugwa k'umupfundikizo wa valve, naho iya kane ni uko gasket y'umupfundikizo wa valve yangiritse cyangwa idapfutswe n'umupfundikizo.
Mu gihe moteri ikoresha imbaraga nke, gazi nke izava ku rukuta rwa silinda n'impeta ya piston ijya kuri crankcase, kandi umuvuduko wa crankcase uzazamuka uko igihe kigenda. Muri iki gihe, valve yo guhumeka ya crankcase ikoreshwa mu kuyobora iki gice cya gazi mu gice cy’ingufu hanyuma ikayishyira mu cyumba cyo gutwika kugira ngo yongere gukoreshwa. Iyo valve yo guhumeka ya crankcase ifunze, cyangwa umwanya uri hagati ya center ya piston n'urukuta rwa silinda ari munini cyane, bigatuma umwuka unyura cyane kandi umuvuduko mwinshi wa crankcase, gazi izava ahantu hadafunze neza, nko mu gasket yo gutwikira valve, imbere n'inyuma, bigatuma moteri iva amavuta.
Igihe cyose ushyizeho agafunga, ugafunga amaboliti, kandi agapfundikizo ka valve kadacitse cyangwa ngo kagire ikibazo, bigaragaza ko agapfundikizo ka valve ari keza. Niba utishimye, ushobora gukoresha ruler n'agapimizo k'ubunini (feeler gauge) kugira ngo upime ubugari bw'agapfundikizo ka valve kugira ngo urebe niba katacitse.
