I-Diesel Fuel Injector yoMgangatho ophezulu 338004X450 Auto Parts for FORD RANGER 2.8D

Njengoko iimfuno zelizwe kukukhutshwa kwezithuthi kunye nokusetyenziswa kwamafutha kusiba ngqongqo ngakumbi, uphuhliso lobuchwepheshe lweenjini zedizili luhamba lusiya kwicala lokusebenza kwamandla aphezulu, ukusebenza kakuhle kwe-thermal kunye nokukhutshwa okuphantsi. Isizukulwana esitsha senkqubo yokutofa kwe-diesel fuel, i-high-pressure common-rail fuel system, sisizukulwana esitsha se-diesel fuel injection system. I-high-pressure common-rail fuel system iyakwazi ukudibanisa umthamo we-injection kunye ne-injection yokulawula ixesha kwiyunithi enye, elawulwa yi-injection, kunye noxinzelelo lwe-injection luzimele kwisantya kunye nomthwalo we-injini. Isitofu sisakhiwo esinzima kakhulu kwaye siyinxalenye ephambili yenkqubo yokutofa kwamafutha. Ukusebenza kwe-injector kunefuthe elithe ngqo ekusebenzeni kwayo yonke inkqubo ye-injection ye-high-pressure common-rail fuel injection, leyo yona inefuthe elibalulekileyo ekusebenzeni kwe-injini. Ke ngoko, kubalulekile ukuphucula iimpawu zenaliti yee-injection kuloliwe oqhelekileyo kwinkqubo yophuhliso lwentsebenzo ye-injini.

I-injector ye-Common Rail elawulwa nge-elektroniki iquka izinto ezintathu ezisebenzayo: i-orifice injectors, i-solenoid valves kunye ne-hydraulic servo system. I-fuel-high-pressure fuel yondliwe ukusuka kumgca we-fuel-high-pressure ukuya kwi-nozzles ye-injector, apho idlula kwi-inlet kunye ne-outlet orifices kwaye ingena kwigumbi lokulawula. Igumbi lokulawula liqhagamshelwe kwi-orifice yokubuyisela i-oyile ngokusebenzisa i-throttle orifice yokubuyela evulwe ngevalve ye-solenoid. Xa i-orifice yokubuya ivaliwe, uxinzelelo oluphezu kwevalve yesitofu senaliti lukhulu kunonyanzeliso kumphezulu woxinzelelo kumzantsi wevalve yokutofa yenaliti, ivalve yesitofu senaliti icinezelwe ngokuchasene nesihlalo sombhobho wesitofu, kwaye akukho mafutha angena kwigumbi lokutsha. Xa ivalve ye-electro-magnetic isebenza, i-orifice yokubuya iyavulwa kwaye uxinzelelo olukwigumbi lokulawula luyehla. Xa amandla asebenza phezulu kwevalve yenaliti yokutofa ingaphantsi kwamandla asebenza kwindawo enoxinzelelo lwevalve yenaliti yokutofa, ivalve yenaliti yokutofa ivula ngokukhawuleza kwaye i-fuel ifakwe kwigumbi lokutsha nge-orifice yesitofu. Kule nkqubo, ngaphezu kwexabiso le-fuel injected in the conmbustion room, kukho i-fuel eyongezelelweyo ephuma ngaphandle kwe-throttle orifice, ebuyiselwa kwi-tank ye-fuel ngokusebenzisa umjelo wokubuyisela.
