Uruhare rw'ingenzi rw'impeta ya piston y'imodoka
Mu "mutima w'imbaraga" wa moteri y'imodoka, impeta ya piston nta gushidikanya ko ari yo irinzi ry'ingenzi, ikora imirimo myinshi y'ingenzi igira ingaruka ku mikorere n'igihe cyo kubaho kwa moteri.
Ubwa mbere, ifite akazi ko gufunga, gafata neza piston n'urukuta rwa silinda, nk'uruzitiro rukomeye, rubuza imyuka ishyuha cyane n'umuvuduko mwinshi mu cyumba cyo gutwika kwinjira mu gikapu, bigatuma umuvuduko uri muri silinda uhoraho kandi igatanga ingufu zihagije kuri moteri. Iyo gufunga binaniranye, ubushobozi bwo gutwika bwa moteri buzagabanuka cyane, kandi ingufu nazo zizagabanuka.
Icya kabiri, ifite akazi ko kugenzura amavuta. Uko piston izamuka ikanamanuka muri silinda, iba nk'icyuma gisukura neza, gikuraho amavuta arenze ku rukuta rwa silinda kugira ngo wirinde ko amavuta yinjira mu cyumba cyo gutwika kugira ngo atwikwe, bityo kikagenzura neza ikoreshwa rya lisansi kandi kikagabanya ikiguzi cyo kuyikoresha. Muri icyo gihe, ishobora gukora firime y'amavuta ku rukuta rwa silinda, igatanga amavuta meza kuri piston n'urukuta rwa silinda, bigagabanya kwangirika.
Byongeye kandi, impeta ya piston ifite inshingano zo kuyobora ubushyuhe no gushyigikira. Mu gihe moteri ikorera mu bushyuhe bwinshi n'umuvuduko mwinshi, ishobora kwimura vuba ubushyuhe bwinshi buturuka hejuru ya piston ikabujyana ku rukuta rwa silinda, hanyuma ikaburekura binyuze muri sisitemu yo gukonjesha, ikareba ko moteri ikora ku bushyuhe bukwiye. Muri icyo gihe, ishobora gufasha kugenda kwa piston no gutanga inkunga ihamye, ikabuza piston gukora ku rukuta rwa silinda no kwangirika.
Ikosa n'ibimenyetso bisanzwe by'impeta za piston z'imodoka
Nubwo impeta ya piston igira uruhare runini, ntabwo byanze bikunze guhura n'amakosa mu gihe ukorera ahantu habi, cyane cyane hagaragara nko kwangirika, kuvunika no gufatana, bigakurikirwa n'ibimenyetso byinshi bigaragara.
Iyo impeta ya piston yambaye ubusa, ubushobozi bwo gufunga bugabanuka, kandi imyuka iri mu cyumba cyo gutwika irasohoka, bigatuma moteri idakoresha ingufu zihagije, umuvuduko wayo ugabanuka, ndetse bikagorana kwihuta cyangwa kuzamuka. Muri icyo gihe, amavuta ashobora kwinjira mu cyumba cyo gutwika kugira ngo atwikwe, bigatuma amavuta akoreshwa yiyongera ku buryo budasanzwe, bigasaba ko amavuta yongera kenshi, kandi umwotsi w'ubururu uzava mu muyoboro w'imyotsi, cyane cyane iyo ikonje itangiye cyangwa yihuta cyane. Byongeye kandi, gutwika kutuzuye bizatuma moteri ikoresha lisansi yiyongera, irenze urugero rw'imyotsi ihumanya, ndetse no kunyeganyega no gushyuha cyane kwa moteri.
Kuvunika kw'impeta ya piston ni ikibazo gikomeye cyane, akenshi giterwa n'ibibazo by'ubuziranenge bw'inganda, kwangirika gukomeye kwa silinda, kuziba kw'ibice bya karuboni, ingano idakwiye y'impeta, cyangwa umutwaro ukabije w'imikorere. Nyuma yo kuvunika, hazabaho amajwi agaragara y'icyuma imbere muri moteri iyo moteri yihuta cyangwa itangiye gukonjesha, kandi ijwi rizarushaho kugaragara. Muri icyo gihe, imbaraga za moteri zizagabanuka cyane, kandi umuvuduko w'amavuta nawo ushobora kuba utari usanzwe.
Gufata impeta ya piston ahanini biterwa n'amavuta yanduye, oxidation ikomeye, gufata impeta ya piston mu muyoboro w'impeta, cyangwa carbon nyinshi zibitswe bigatuma umuyoboro w'impeta ufunga. Gufata bituma impeta ya piston itakaza ubushobozi bwo guhagarara neza kandi ntifatanye neza n'urukuta rwa silinda, bigatera ibimenyetso bimwe byo gufunga, kwiyongera k'ikoreshwa ry'amavuta, no kugabanuka k'imbaraga.
Uburyo bwo gusuzuma no gukemura ibibazo by'impeta ya piston y'imodoka
Iyo ikinyabiziga kigaragaje ibimenyetso byavuzwe haruguru, ni ngombwa gusuzuma impeta ya piston ku gihe. Uburyo busanzwe bwo gusuzuma burimo gusuzuma endoscope, kureba aho karubone iri hejuru ya piston n'amavuta ari mu mwobo w'impeta unyura mu mwobo w'imashini; ikizamini cy'umuvuduko wa silinda, niba umuvuduko wa silinda ari usanzwe ariko hari amavuta menshi akoreshwa, akenshi biba ari ikibazo cy'impeta ya piston; uburyo bwo kureba ibintu bukoresha imbaraga, gufunga umwobo w'amavuta mu gihe cy'ubukonje, kumenya aho umwuka usohoka no gukoresha agakoresho ko gupima umwuka unyura; kugenzura uburyo bwo gukuramo umwuka, gushyira imbere igenzura ry'ibice byoroshye kwangirika nka valves na turbochargers, hanyuma hakemezwa ikibazo cy'impeta ya piston; ikizamini cy'umuti wo gusana, kongeramo umuti wo kurekura impeta ya piston no gukurikirana ihinduka ry'imikoreshereze y'amavuta kugira ngo hamenyekane urwego rwo gufata.
Ku makosa atandukanye, ibisubizo nabyo biratandukanye. Ku mburagasaro nto cyangwa zifata, agakoresho kadasanzwe ko gusana impeta ya piston gashobora gukoreshwa mu gusubiza uburimbane no gufunga impeta ya piston nta gutandukanya moteri. Urugero, "Siyou Pu 2 + 18 idasenya ikoranabuhanga" ishobora gukora ku miterere y'impeta ya gazi n'iy'amavuta icyarimwe, igakora ibikorwa byo gusana mu gihe cyo kuyitwara kugira ngo wirinde ibyago byo kwangirika. Niba impeta za piston zashaje cyane cyangwa zarangiritse, zigomba gusimburwa ako kanya. Mu kuzisimbuza, ni ngombwa guhitamo ibikoresho byizewe no kujya mu iduka rya 4S ry'abahanga cyangwa iduka ryo gusana, aho abakozi b'inzobere bazakora icyo gikorwa. Kubera ko gusimbuza impeta za piston bisaba gusenya moteri, inzira iragoye. Iyo kuyishyiraho idakozwe neza, bishobora kugira ingaruka ku mikorere ya moteri ndetse bigatera n'ingaruka zikomeye. Byongeye kandi, mu gihe cyo gutwara imodoka buri munsi, guhindura amavuta ya moteri buri gihe n'akayunguruzo k'amavuta, gukoresha lisansi nziza, no kwirinda ko moteri ikora igihe kirekire bishobora kongera igihe cy'imikorere y'impeta za piston no kugabanya ibibazo.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
