Diesel Injector Fuel Injector 095000-5361 Denso Injector yeIsuzu

Yechishanu ndiyo yekuona magetsi jekiseni remafuta. Bvisa plug yewaya yeinjector yemafuta, batidza kiyi yekubatidza, gadzirisa multimeter kusvika kuDC voltage level, kuyera voltage pawaya plug, batanidza plug neiyo dzvuku bvunzo lead yemultimeter kuti ubate mapini maviri eiyo. plug zvichiteerana, uye batanidza imwe nhema bvunzo inotungamira kugomba reinjini, uye ma voltages ari 12V (iyo bhatiri voltage panguva iyoyo) uye OV zvakateerana. Kana iwo ese ari OV, zvinoratidza kuti pane dambudziko nemagetsi injector magetsi, uye bhokisi rinoenderana nefuse uye midziyo yemagetsi inofanirwa kuongororwa.
Yechitanhatu ndeyekuongororwa kweinjector control circuit. Bvisa plug yehuni jekiseni waya, batidza kiyi yekudzima, iyo dzvuku yekuyedza inotungamira yemultimeter yakabatana nemapini maviri eplug zvichiteerana, uye imwe nhema inotungamira yekuyedza yakabatana nekesi yeinjini, mavoltages ari 12V uye 0V. zvakateerana, tsvaga iyo 0V pini uye Maka iyo, iyi ndiyo injector control circuit. Batanidza plug yewaya yeinjector yemafuta, vhura kiyi yekudzima, uye uyere voltage pakati peiyo mafuta injector control line nekesi yeinjini, iyo inofanirwa kunge yakakura kupfuura 10.5V. Imwe nzira ndeyekuedza nepeni yemotokari yemagetsi yekuedza, ine madhiodhi maviri anobudisa chiedza, kusunungura plug yehuni injector waya, batanidza mapini maviri emotokari yemotokari yepini kumapini epuragi, uye shandisa chinotangira kudhonza Tanga injini. , tarisa madhiodhi, ma LED anofanirwa kuvheneka neimwe nzira, zvichiratidza kuti chiratidzo chekudzora chakajairika.
Yechinomwe kuona chiratidzo chejekiseni remafuta. Tarisa iyo mafuta jekiseni kupuruzira upamhi nerubatsiro rweinjini yekutadza kuongorora chiridzwa kana oscilloscope. Mumamiriro ezvinhu akajairika, jekiseni remafuta kupuruzira hupamhi hweinjini ndeye 2 ~ 10mS. Kazhinji, kuona kwakakamurwa kuita nhanho ina, imwe idling nhanho; imwe yacho idanho diki nepakati pekutakura; chechitatu idanho rinorema mutoro. Aya matanho matatu ndeekutarisa kufanana kwega rega silinda mafuta jekiseni chiratidzo. Yechina ndiyo danho rekucheka mafuta resitiroko. Kana injini ichivhara throttle nekukasira nekumhanya kukuru, jekiseni remafuta rinofanira kumisa jekiseni remafuta kwenguva pfupi, uye jekiseni remafuta pulse wide i0mS munguva pfupi.
