Isitofu se-Diesel Fuel Injector 095000-5361 Denso Injector ye-Isuzu

Eyesihlanu kukubona amandla okufaka isitofu samafutha. Khupha iplagi yocingo yesitofu se-fuel, vula isitshixo sokutshixa, lungisa i-multimeter ukuya kwinqanaba le-voltage ye-DC, ukulinganisa i-voltage kwiplagi yocingo, qhagamshela iplagi kunye nesikhokelo sovavanyo olubomvu lwe-multimeter ukuze uchukumise izikhonkwane ezimbini zeplagi. iplagi ngokulandelelanayo, kwaye uqhagamshele olunye uvavanyo olumnyama olukhokelela kwiqokobhe le-injini, kwaye amandla ombane ayi-12V (umbane webhetri ngelo xesha) kunye ne-OV ngokulandelelanayo. Ukuba zonke ziyi-OV, oko kubonisa ukuba kukho ingxaki yokunikezelwa kwamandla ombane we-fuel injector, kunye nebhokisi ye-fuse ehambelanayo kunye nezixhobo zombane kufuneka zihlolwe.
Okwesithandathu kukuhlolwa kwesekethe yokulawula i-injector. Khupha iplagi yocingo lwesitofu sokutshiza, vula isitshixo sokutshixa, intambo ebomvu yovavanyo lwemultimeter iqhagamshelwe kwizikhonkwane ezimbini zeplagi ngokulandelelanayo, kwaye enye iplagi yovavanyo emnyama iqhagamshelwe kwimeko ye-injini, i-voltages yi-12V kunye ne-0V. ngokulandelelana, fumana i-pin ye-0V kwaye uyiphawule, le yisekethe yokulawula i-injector. Qhagamshela iplagi yocingo ye-injector ye-fuel, vula i-lock lock, kwaye ulinganise i-voltage phakathi komgca wokulawula isitofu se-fuel kunye ne-injini ye-injini, ekufuneka ibe mkhulu kune-10.5V. Enye indlela kukuvavanya ngepeni yokuvavanya yombane yemoto, ene-diode ezimbini ezikhupha ukukhanya, ukukhupha iplagi yocingo lwe-injector ye-fuel, qhagamshela izikhonkwane ezibini zepeni yovavanyo lwemoto kwizikhonkwane zeplagi, kwaye usebenzise umqalisi ukutsala Qala injini. , jonga ii-diodes, ii-LED kufuneka zikhanyise ngokuhlukileyo, zibonisa ukuba uphawu lokulawula luqhelekileyo.
Okwesixhenxe kukufumanisa umqondiso wenaliti yesitofu. Jonga ububanzi benaliti yesibaso ngoncedo lwesixhobo sokufumanisa ingxaki ye-injini okanye i-oscilloscope. Phantsi kweemeko eziqhelekileyo, i-injini ye-injection ye-fuel pulse ububanzi yi-2 ~ 10mS. Ngokubanzi, ubhaqo lwahlulahlulwe lwaba ngamanqanaba amane, elinye linqanaba le-idling; enye inqanaba lomthwalo omncinci kunye nophakathi; eyesithathu yinqanaba lomthwalo onzima. Ezi zigaba zintathu kukukhangela ukufana kwesiginali yenalinda yesibaseli ngasinye. Eyesine linqanaba lokuyeka amafutha e-stroke. Xa i-injini ivala i-throttle ngokukhawuleza ngesantya esiphezulu, isitofu se-fuel kufuneka siyeke naliti yamafutha ixesha elifutshane, kunye ne-fuel injection pulse width yi-0mS ngexesha elifutshane.
