Umgangatho oPhakamileyo kaloliwe oqhelekileyo weDizili / uMbhobho wesitofu seFuel DLLA145P014

Ukuqhaqha kunye nokuHlolwa kweNtloko ye-Injector kunye neZakhono zokuSila zokuLungisa i-Needle Valve Coupling (icandelo 1)

I-injector yamafutha yenye yezona zinto zibalulekileyo ze-injini ye-diesel, kwaye ukusebenza kwayo kuchaphazela ngokuthe ngqo amandla, uqoqosho, ukuthembeka kunye nokukhutshwa kwe-injini ye-diesel.

Xa i-injini ye-diesel isebenza ngesantya esiphezulu, i-fuel efakwe kwi-cylinder esuka kwisitofu se-fuel kufuneka ivuthwe ngokukhawuleza, kwaye itshise ngokukhawuleza ngexesha elifanelekileyo, ukuze kuguqulwe amandla ekhemikhali yesibaso kumandla omatshini. leyo iqhuba injini ukuya kowona mgangatho uphezulu.Ukufezekisa oku, i-injector kufuneka ihlangabezane nezi mfuno zilandelayo:

(1) Isitofu se-fuel kufuneka sibe noxinzelelo oluthile lwesitofu kunye noluhlu.

Uxinzelelo lwenaliti ye-injector lusetwa luxinzelelo olulawula intwasahlobo, kwaye uluhlu aluhambelani kuphela noxinzelelo lwenaliti kunye noxinzelelo lwangasemva lwegumbi lokutsha, kodwa lukwanxulumene nezinto ezakhiweyo ezifana nobubanzi bomngxuma wombhobho kunye ukumila kwevalve yenaliti.

(2) Kufuneka kubekho indlela efanelekileyo yokutofa kunye ne-engile yekhowuni yesitofu ehambelana nokumila kwegumbi lokutsha.

(3) Kufuneka kubekho ukusebenza kakuhle kwe-atomization, oko kukuqinisekisa ukuba i-fuel injected inokukhawuleza kwaye ixutywe kunye nomoya ukuze ufumane ukutsha okwaneleyo.

(4) Ixesha lokumisa isitofu samafutha licocekile, oko kukuthi, ukunikezelwa kwamafutha kunokupheliswa ngokukhawuleza nangokupheleleyo ekupheleni kwenaliti yamafutha, kwaye akukho kuvuza kwamafutha kuvunyelwe.

(5) Kufuneka ikwazi ukumelana neemeko ezinzima ezifana nokushisa okuphezulu kunye noxinzelelo oluphezulu, ukwenzela ukuba isetyenziswe ngokukhuselekileyo ixesha elide.Ngenxa yokuba isitofu samafutha sisesichengeni sobushushu obuphezulu kunye negesi yoxinzelelo oluphezulu, iqondo lobushushu kunye noxinzelelo lutshintsha ngesiquphe, kunye nesantya esiphezulu sokuhamba kwepetroli, ukungcola kwepetroli kuyaguga kunye negesi etshabalalisayo (i-sulfur dioxide) eveliswa kwi-fuel corrodes kwaye iguge.

Ngoko ke, ukwenzela ukugcina i-injector ye-fuel isesimweni esihle sokusebenza, kuyimfuneko ukuqinisa ukuhlolwa rhoqo kunye nokugcinwa kwamacandelo egumbi lokutsha kwe-injini kunye nenkqubo yamafutha.
