Ukulandelelana kwe-Disassembly kunye neNdlela yoLondolozo lwe-Fuel Injector ye-injini ye-Diesel

Isitofu samafutha sikwayinxalenye ebalulekileyo yenkqubo yokubonelela ngamafutha enjini yedizili.Umsebenzi walo ukutshiza ioli ye-diesel ephezulu yoxinzelelo kwipompo ye-injection ye-fuel ukuya kwigumbi lokutsha ngendlela yenkungu, kwaye wenze umxube ovuthayo ovuthayo kunye nomoya oxinyiweyo kwigumbi lokutsha.I-injector ye-fuel ayigxininisi kuphela umgangatho wokutshiza we-diesel, intsebenziswano phakathi kwe-oyile ye-oyile kunye negumbi lokutsha, kodwa ikwachaphazela i-angle yokungena kwangaphambili, ixesha lokutofa kwe-fuel kunye ne-injection ye-fuel rhoqo, enempembelelo ngqo ekusebenzeni injini.Ngoko ke, iimfuno ezisisiseko zomsebenzi we-injector zezi: i-injection ethile yoxinzelelo kunye noluhlu, kunye ne-angle ye-cone yokutshiza efanelekileyo, kunye nomdlalo kunye nokuma kwegumbi lokutsha.Ukongeza, inaliti yamafutha inokumiswa ngokukhawuleza ekupheleni kwenaliti yamafutha ngaphandle kokuthontsiza kweoli.

enye: ukugcinwa kwesitofu samafutha

Emva kokucoca iinxalenye ze-injector, ukuba kukho naziphi na iimeko ezingaqhelekanga ezilandelayo zifunyenwe, kufuneka zilungiswe okanye zitshintshwe.Xa isiphelo somzimba wesitofu sidityaniswe nevalve yenaliti inomonakalo omncinci, khupha izikhonkwane ezibini zokumisa kwaye usile ipleyiti Gaya.Lumka ungabambi umphezulu orhabaxa xa ukhupha iphini lokubeka.
② Xa umphezulu woxinzelelo olawula intwasahlobo ye-injector ye-fuel ikrwela, igxothwe okanye ikhubazeke ngokusisigxina, kufuneka itshintshwe.
③ Iidiphozithi zekhabhoni kwincakuba yegxalaba elingaphakathi kunye nodonga lomngxuma we-injector tight cap kufuneka isuswe ngokupheleleyo.
④ Ubukhulu becala lokudibanisa umbhobho wenaliti yamafutha bunxityiwe, kwaye kufuneka itshintshwe ukuba kukho ukuvuza okumandundu kwe-oyile.
⑤ Xa imingxuma yombhobho ineziphene ezifana nokuguga kunye nokwandiswa, ezo zichaphazela umgangatho wokutshiza kufuneka zitshintshwe.
⑥ Ukuba isihlalo sokutywina sobuso bevalve yenaliti kunye nomzimba wevalvu yenaliti awugugi kakhulu, unokulungiswa ngokusila ngokulinganayo nge-alumina abrasive paste.Xa ugaya omnye nomnye, ungasebenzisi amandla amaninzi, kwaye indawo yokutywina ingafikelela kwiyunifomu kwaye ingabi nebhanti yokutywina ebanzi.
⑦ Ngenxa yokubuya ngasemva kwegesi kwi-cylinder ye-diesel injini okanye ukungena kokungcola okuhle kwi-injector yamafutha, ivalve yenaliti iba mnyama okanye ixinge.Emva kokucoca kunye nophando oludibeneyo, lunokusetyenziswa kwakhona okanye lutshintshwe ngokobunzima bemeko.

ezimbini: Imiba efuna ukuqwalaselwa kwindibano yesitofu

① Ngexesha lonke lenkqubo yokuhlanganisa i-fuel injector, iindawo kufuneka zigcinwe zicocekile, ngakumbi izitywina zendibano ye-injector yamafutha ngokwawo kunye nesiphelo somzimba wesitofu.Kwanobutyobo obuncinci kunye nothuli lunokubangela ukuvaleka kokutyibilika kwaye Ukutywinwa komphezulu woqhagamshelwano kubi.Umphezulu wescapular apho umphezulu oqinileyo we-injector ye-fuel uqhagamshelana ne-injector ye-fuel kufuneka ube mpuluswa kwaye ube mcaba, kwaye akukho zidiphozithi zekhabhoni okanye i-burrs zivumelekileyo, kungenjalo iya kuchaphazela ukuqina kunye nokuma kofakelo lwendibano ye-injector yamafutha, ngaloo ndlela ibangela Ukutyibilika kwesitofu samafutha kubi.
② Xa udityaniswa, qala ngoku jija umbhobho we-oyile odityanisiweyo oxhotyiswe kwangaphambili ngondoqo wesihluzi se-oyile, kwaye ucinezele igasket yobhedu ukuze uqinise itywina ngaphandle kokuvuza kweoyile.Emva koko faka uxinzelelo olulawula intwasahlobo kunye nentonga ye-ejector kumzimba wesitofu, jija isikrufu solawulo loxinzelelo de ichukumise nje intwasahlobo elawula uxinzelelo, kwaye emva koko ujije i-nut elawula uxinzelelo.
③ Gxotha isitofu samafutha sijonge phantsi kwibhentshi vise, faka indibano yesitofu samafutha, kwaye uqinise ikepusi.I-torque yokuqinisa i-59-78 Nm (6-8kgf.m).Itorque eninzi kakhulu iya kubangela ukuguqulwa komzimba wevalve yenaliti, echaphazela ukusebenza kwevalve yenaliti, kunye netorque encinci kakhulu iya kubangela ukuvuza kweoyile.
④ Indibano ye-injector ye-fuel edibeneyo kufuneka ivavanywe kwibhentshi yokuvavanya ukutywinwa kunye nokutshiza, kunye noxinzelelo lokuvula lwesitofu samafutha kufuneka luhlengahlengiswe.
