Isitofu se-Diesel Fuel Injector 5396273 Denso Injector for Cummins, Front Axle

1. Iimpazamo eziqhelekileyo zezitofu ze-injini ezilawulwa ngombane
Ukungaphumeleli kwe-injector ye-injini elawulwa nge-elektroniki ayibangeli kuphela ukuzinza kunye namandla e-injini ukuba iyancipha, kodwa ichaphazela nokusebenza okuqhelekileyo kwe-injini yemoto, okubangela ukuhla kozinzo lwamandla e-injini.Iimpazamo eziqhelekileyo zezi: ukuthontsiza, inaliti yefutha engachanekanga, inaliti yamafutha engaqhelekanga, njl.Isixa samafutha esitofwa sisitofu kunye nokufana konikezelo lwamafutha kwisilinda ngasinye nako kuya kubangela ukuthontsiza okanye ukumisa inaliti yamafutha.
Okwesibini, ukufunyanwa kwee-injection ze-injini ezilawulwa ngombane
1. Ukulinganisa ukuchasana kwekhoyili ye-electromagnetic ye-injector ye-fuel injector inokubonwa kwisithuthi, okanye inokulinganiswa emva kokuba isusiwe.Indlela yokulinganisa kunye nomgangatho zezi: khupha iplagi ye-harness ye-injector ye-fuel, ukulinganisa ukuchasana phakathi kwee-terminals ezimbini ze-injector ye-fuel nge-multimeter, umbutho osemgangathweni malunga ne-12 ~ 162 (uhlobo oluphezulu lwe-impedance) okanye 3 ~ 62 (uhlobo oluphantsi lwe-impedance). ).
2. Qwalasela umbane wombane we-electromagnetic injector.Umbane wombane wombane we-injector ye-fuel unokuvavanywa nge-pointer okanye i-multimeter yedijithali.Xa uvavanya, qala ukhuphe iitheminali ezimbini zesitofu ngasinye ngokulandelelanayo, uze uvule iswitshi yokutshisa.Ukuba i-injini isenako ukuqalisa ngokuqhelekileyo, ngoko ke kuphela amandla ombane anokubonwa.Umgangatho kufuneka ube ngaphezu kwe-12V (i-voltage yamandla ombane wesithuthi), kwaye inqanaba eliphantsi kufuneka libe yi-0V.Ukuba isekethe yamandla iyekisiwe kwaye amanqanaba aphezulu naphantsi phakathi kweetheminali ezimbini zeplagi yokubopha kunye ne-injini zingu-zero zombini, ngoko ke i-fuse ye-injection fuel kunye ne-fuel pump relay kufuneka ihlolwe ngokwahlukeneyo.
