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 nje kuphela ukuzinza kunye namandla e-injini ukunciphisa, kodwa kuchaphazela nokusebenza okuqhelekileyo kwe-injini yemoto, okukhokelela ekunciphiseni ukuzinza kwamandla e-injini. Iimpazamo ezixhaphakileyo 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 yombane wesithuthi), kwaye inqanaba eliphantsi kufuneka libe yi-0V. Ukuba isekethe yamandla iqhawulwe kwaye amanqanaba aphezulu naphantsi phakathi kweetheminali ezimbini zeplagi yokubopha kunye ne-injini zingu-zero zombini, ngoko ke i-fuse yenaliti yamafutha kunye ne-fuel pump relay kufuneka ihlolwe ngokwahlukeneyo.
