Impompo-umlomo: zohlelo kunye nokulungiswa

Qho ngonyaka ekufunweni injini idiesel ngokwemimiselo ezifana amandla, imvelo Uqoqosho luyakhula kuphela. Kwaye nje ukuyilwa ogqibeleleyo ngomxube enokutsha kunokwanelisa ezi mfuno. Ngoko ke, yonke inkqubo ziphene fuel ukuba ukusebenza ngendlela eyiyo, ngokubonelela umzuzu kutshizwa phantsi koxinzelelo oluphezulu.

Loo inkqubo, okuhlanganisa kwelinye kwiyunithi kwamafutha injector nempompo, nempompo-atomizer. Ngokufanayo, impompo ukunyuka koxinzelelo, impompo-injector sifaka isixa esithile umxube ngexesha elifanelekileyo. Ngenxa yokuba ngasinye yimiqulu injini kukho enye iyunithi injector, kule nkqubo akukho pump elekhtrons.

nemilomo izixhobo ziquka intloko cylinder othambekele unit diesel injector. Ukuze ndibase ukusebenza kwi camshaft 4 uye cam okhethekileyo. Amandla phezu plungers iyunithi injectors usasazwa ugqithiselwa ngokusebenzisa kang. Ngenxa iprofayile eyodwa yeyunithi injector yesitshixo cam lokuqhuba liphuma kuqala kakhulu, yaye emva koko uwela kuhle.

Ngalo mzuzu xa kukho ukunyuka elibukhali yengalo yesitshixo, ibhola licinezelwe ngesantya esikhulu phantsi. Ngoko ke, kukho uxinzelelo oluphezulu lwegazi. Xa ingalo yodwa eqalisa kuwa ngokucothayo, njengoko impompo liqala isantya kunye nentshukumo efanayo phezulu. Loo sakhiwo ivumela amafutha ukuba bangene kwigumbi eliphezulu xi kakuhle, kungekho ukuyilwa amaqamza. Ixesha Ixesha kunye ulawulo ziphene yolawulo vana solenoid unit injector. Ukulungiselela le njongo, ngokusebenzisa i-electronic iyunithi yolawulo ekhutshwe kunye ombane. Nkqu ezinxaxhileyo ezincinane parameters zezityalo kwenzeka xa amafutha zokutshiza, i-injini uqalisa 'ingxolo. "

Impompo injector Diesel unokuba kweentlobo ezintathu: piezoelectric, umoya, electrohydraulic. Nge solenoid valve umlomo njengephepha iinjini ipetroli nedizili, kwaye ilungiselelo elula: esatsiba yaye ivelufa solenoid ngenaliti spray. I electro-injector ifakiwe kuphela iinjini idizili, apho kunokwenzeka ngakumbi ukuba sisebenze kwinkqubo Caumont Ryle. Piezoelectric ingqalelo iinjini diesel eziphambili kakhulu. Loo iyunithi injector kubangelwa amaxesha 4 ngokukhawuleza ngaphezu kokuba solenoid, kwaye ngokwemithamo lesitofu amafutha ngokuchanileyo esiphezulu.

Ukulungiswa injectors kufuneka yenziwe xa kukho ezi mpawu zilandelayo: ukusetyenziswa kakhulu amafutha kakhulu, nakanjani xa shaya le emoto, ukuvuza amafutha okanye kokuphuma kwinkqubo zeemoto. Ibalula Isantya imoto ingazinzi: inaliti tachometer usoloko "jump" ngaphandle kwesizathu. Ukukhangela nemilomo kunye nokulungiswa yabo lwenziwa kwi nqwelo ezikhethekileyo, ngoko ke kunzima ukuba balungise ngokuzimeleyo: emisela uxinzelelo% 10 kuphela ngaphezu ngegama lungunobangela lokungaphumeleli kwi-injini. Yaye ukuba umsebenzi kwenkqubo amafutha ayiniki kubangela inkxalabo, uxilongo injector - yomsebenzi kucetyiswa emva zonke 60 000-70 000 km yeemoto run.
