Into eyenzekayo emva kokuba i-valve yesitofu senaliti yokutshisa isitsha kukuba xa injini isebenza, akukho tshintsho kwimeko yokusebenza kwe-injini xa uqinisa okanye ukhulula uxinzelelo lokulawula isikrufu kwi-injector yamafutha. Ukongeza, ngenxa yeendawo ezahlukeneyo apho inaliti ye-injector itshiswe khona, i-phenomena eboniswe xa injini isebenza nayo yahlukile.

Xa ivalve yenaliti itshiswe yavuleka kwaye injini ibaleka, kuya kubakho isandi esingaqhelekanga sokunkqonkqoza kwentsimbi kwisilinda. Ngelo xesha, umbhobho wokukhupha uya kwenza kwakhona isandi esithi "pop, pop", kwaye i-exhaust iya kuba grey-white. Ubushushu bombhobho we-oyile we-high-pressure we-injector nawo uphezulu kunezinye iisilinda. Ngeli xesha, ukuba isandi sokunkqonkqoza siyanyamalala ngexesha lokuhlolwa kwe-oil cutoff, xa umbhobho we-oyile woxinzelelo oluphezulu ukhululiwe, i-fuel iya kutshizwa kwindawo ekhululiwe.

Xa i-valve yenaliti itshiswa kwimeko evaliweyo, i-valve yenaliti ayisebenzi xa injini isebenza, ngoko ubushushu bombhobho we-oyile woxinzelelo oluphezulu lwale silinda lungaphantsi kunezinye iisilinda. Xa i-cylinder inqunyulwa ukuze ihlolwe ioli, akukho tshintsho ekusebenzeni kwenjini. Ukusuka kumbhobho we-oyile woxinzelelo oluphezulu Jonga indawo ekhululekileyo, i-fuel kuphela ifakwe isitofu, hayi umoya.

(1)Indlela yokudibanisa engalunganga

① I-oyile ye-anti-rust ayizange isuswe xa kufakwa i-oyile entsha. Ukuze kuthintelwe umhlwa ngexesha lokugcinwa kunye nokuthutha, i-nozzle ye-injection ye-fuel idla ngokugqunywa ngomaleko we-oyile ye-anti-rust. Xa utshintshela i-fuel injector, ukuba le oli ayicocwanga, i-oyile ye-anti-rust iya kubambelela kwi-valve yenaliti kumaqondo aphezulu okushisa, okubangela ukuba i-valve ye-injector ye-fuel itshise.

② Ukuvuza kwedizili kwi-injector yamafutha. Xa isiphelo sobuso be-fuel injector bumanzi ngenxa yokuvuza kwe-diesel, kunokubangela ukutshiswa kwendawo, kwaye ubushushu bokutsha bugqithiselwe ngokuthe ngqo kwi-injector ye-fuel, ebangela ukuba i-valve yenaliti ivuthe.

③ Xa ufaka inaliti yamafutha, intambo ye-asbestos kunye nezinye izinto zokugquma ziyasetyenziswa endaweni yeegaskets zobhedu, ezichaphazela ukutshatyalaliswa kobushushu bombhobho wenaliti yamafutha. Inxalenye yesikhokelo sevalve yenaliti yesitofu senaliti iya kutshisa ngokugqithisileyo, nto leyo ebangela ukuba ivalve yenaliti ingabi bhetyebhetye okanye ixinge.

④ Xa ufaka i-injector yamafutha, i-torque yokuqinisa i-screw sleeve inkulu kakhulu, ethintela ukuhamba kwevalve yenaliti.

⑤Isithuba esidibanayo phakathi kwesitofu se-fuel kunye nomngxuma wesihlalo sesitofu sesitofu sincinci kakhulu. Ngale ndlela, xa ubushushu be-injini buphezulu, umsantsa omncinane wokuqala wevalve yevalvu yenaliti uyatshatyalaliswa, nto leyo ebangela ukuba ivalve yenaliti yokutofa ivuthe.

(2) Kukho ukungcola kumgca weoli yeoli

I-oyile ye-diesel iqulethe amasuntswana amaninzi angcolileyo akhulu kakhulu, okwangoku esona sizathu siphambili sokutshisa i-valve yenaliti ye-injector. Isihluzo samafutha esisetyenziswa yi-injini sinokuhluza kuphela ukungcola okungaphezulu kwe-0.05 mm. Ngokucacileyo, isakhono sokuhluza asinamandla kakhulu. Ukuba i-fuel filter element igqabhukile ngeli xesha, iipads eziphezulu kunye nezantsi ezizivayo ze-filter element zilahlekile okanye zonakaliswe, ezibangela ukuba inxalenye yepetroli ingene ngokuthe ngqo kwimpompo yokutofa kwamafutha, kwaye ukungcola kuyo kungangena kwi-injector fuel. yivale.

(3) Iqondo lobushushu le-injini liphezulu kakhulu kwaye ivelufa yenaliti itshisiwe.

① I-injini ihlala ibaleka ngesantya esiphantsi ixesha elide, nto leyo ebangela ukuba ukuncipha koxinzelelo lwe-injector ye-injector, kwaye i-oyile ingena ijikeleze i-injector ukwenza iidiphozithi zekhabhoni, ibangela ukuba ubushushu bunyuke kwaye butshise ivalve yenaliti.

② I-oyile iqhubela kwindawo yokutshisa kwaye ibangele idiphozithi enkulu yekhabhoni kwi-injector yamafutha emva kokutsha, okwenza kube nzima ukuba ubushushu buphume kwi-injector ye-fuel kunye nokubangela ukuba i-valve yenaliti ivuthe.
