Ukuhlolwa kofakelo kunye nohlengahlengiso lwempompo yokutofa kwamafutha kwi-injini ye-diesel

Impompo yokutofa ngamafutha yinxalenye ebalulekileyo yenkqubo yamafutha enjini yedizili. Imeko yayo yokusebenza ichaphazela ngokuthe ngqo amandla, uqoqosho kunye nokuthembeka kwe-injini ye-diesel. Umsebenzi wayo kukwandisa uxinzelelo lweoyile, ukulawula ixesha lokutofa, kunye nevolumu yokutofa ukulungisa isantya senjini yedizili. kunye namandla njl.
I-valve yokukhupha i-oyile kunye ne-plunger yempompo yokutofa kwe-fuel zizo zonke iindawo ezichanekileyo zokudibanisa, ezimele zisetyenziswe njengesethi kwaye azivumelekanga ukuba zitshintshwe.
Xa ufaka impompo yesitofu se-fuel, isibambo sokuqalisa kufuneka sitsalwe kuqala ukuze i-roller ibe kwindawo ephantsi. Lungisa izalathisi kwifolokhwe yokutshintsha kunye nempompo yokutofa kwepetroli embindini womngxuma wokubona, emva koko ucinezele impompo yesitofu se-fuel endaweni, jika ifolokhwe ye-shift ukuze ubone ukuba isalathisi sihamba kunye nefolokhwe yokutshintsha, ukuba kunjalo, qinisa phezulu. amantongomane amabini kuqala , kwaye emva koko ufake kwaye uqinise i-gasket, i-cover plate kunye ne-nut ngokulandelelana. Kungenjalo, khupha impompo yokutofa kwamafutha, kwaye ulungise indawo yefolokhwe yeshifti kunye nesalathisi ukuze zidibane.
Susa umbhobho we-oyile woxinzelelo oluphezulu wempompo yokutofa ngamafutha, vala indawo yokuphuma yamafutha yempompo yokutofa ngeminwe yakho, kwaye utsale umqheba wokuqala. Ukuba uziva ngathi uxinzelelo lwenaliti yepetroli luphezulu, unokucinga kwangaphambili ukuba impompo yokutofa ngamafutha ilungile. Ukuba uva ukuba uxinzelelo lwenaliti yamafutha luphantsi, oko kuthetha ukuba ukusilela kwempompo yesitofu samafutha. Susa isihlalo esixineneyo sevalve yokukhupha ioyile kwaye ujike i-flywheel ukuze ubone ukuba iplunger iyehla inyuka na. Ukuba ayihambi ezantsi, oko kuthetha ukuba i-plunger spring yaphukile okanye i-plunger ixingelwe kufutshane neziko eliphezulu elifileyo. Kungenjalo, jonga ukuba kukho i-oyile yedizili ephuma kumngxunya wevalve yeoyile xa iplunger isihla. Ukuba akunjalo, kuthetha ukuba i-oil inlet hole yepompo yeoli ivaliwe kwaye kufuneka icocwe. Ukuba uxinzelelo lonikezelo lweoyile lwempompo yokutofa kwamafutha luphantsi kakhulu kwaye umthamo wonikezelo lwepetroli uncinci, kuyafuneka ukuba kugxininiswe ekujongeni ukuba umngxuma wokungeniswa kweoyile wempompo yokutofa kwamafutha uvaliwe, nokuba isibini se-plunger sinxitywe kakhulu, nokuba isibini sevalve yokukhupha amafutha kunye necamshaft zinxitywe kakhulu.
Lungisa isiphatho se-throttle kwindawo yokuqala, qala ujike i-flywheel ngokwewotshi ngokukhawuleza de kuphume umbhobho wenaliti yamafutha. Uze ujike kancinane i-flywheel ngasekunene, kwaye uyeke ukujika emva kokuba umbhobho wokutofa ngamafutha uphumile. Jikelezisa i-flywheel ngokuchasene newotshi ukuya malunga ne-90 degrees emva kwendawo ephezulu efileyo, kwaye usule amafutha ashiyekileyo kwindawo yokukhupha umbhobho we-fuel injection nge-rag. Emva koko jika ngokucothayo ivili elijikelezayo ngasekunene, kwaye ujonge ukuphuma kombhobho wenaliti yamafutha ngeli xesha. Xa kukho uphawu lweoli ephuma kwindawo yokuphuma, yeka ukujikeleza i-flywheel. Funda ixabiso lomgca okroliweyo kwi-flywheel ehambelana ne-top dead center mark ye-box body, eyi-engile yobonelelo lwamafutha kwangaphambili ngeli xesha.
I-engile esemgangathweni yokutofa i-fuel advance i-engile yi-17-19 degrees. Ukuba ukufundwa kukhulu kune-19 degrees, ubukhulu be-gasket yokulungelelanisa phantsi kwepompo ye-injection ye-fuel kufuneka kwandiswe; ukuba ingaphantsi kwama-degrees angama-17, ubukhulu be-gasket yokulungelelanisa phantsi kwepompo ye-injection ye-fuel kufuneka buncitshiswe. Ngokuqhelekileyo, ubukhulu be-gasket bunyuswe / buyancipha nge-0.1mm, kwaye i-angle ye-injection ye-fuel advance ilibazisekile / iqhubela phambili nge-1 degree.
