Maitiro ekutarisa iwo kuvesa koira ine multimeter
Zviri mukati
Kana iyo coil yekurasa ikatadza, injini yemota yazvino inomira kutanga. Computer diagnostics yemotokari haigare ichitarisa kusashanda kwecoil; pakadai, nzira yekare uye yakaratidza yekutarisa uchishandisa chishandiso chepasirese (multimeter) mune ohmic yekuyera muyero modhi haikundike.
Chinangwa checoil yekuvesa nemhando dzayo
Coil yekuvesa (inonziwo bhabhini) inoshandura simba remagetsi kubva pabhatiri rebhodhi kuita yepamusoro voltage, inoiswa kumaraki emoto anoiswa mumasirinda, uye inogadzira magetsi emoto muparaki yemhepo. Pombi-yakadzika-mhepo inopisa inogadzirwa muchopper (muparidzi), switch (kuvesa gudzazwi) kana injini yekudzora yuniti (ECU).
Nekuparara kwemagetsi kwepark plug mweya mweya weakarongeka e0,5-1,0 mm, kupomba ine voltage inosvika mashanu kilovolts (kV) pa5 mm yegap inodiwa, i.e. simba remagetsi rine voltage inosvika gumi kV rinofanira kuiswa kukenduru. Kuti uve nekuvimbika kukuru, uchifunga nezvekugona kwemagetsi muwaya dzekubatanidza uye imwe yekudzora inodzivisa, iyo voltage inogadzirwa neiyo coil inofanira kusvika kusvika ku1-10 kV.
Chenjerera! Iyo yakakwira voltage kupisa kubva kune iyo kuvesa coil kune njodzi kuvanhu uye kunogona kutokonzeresa magetsi magetsi! Kubuda kune njodzi kune vanhu vane chirwere chemwoyo.
Chigadziro coil mudziyo
Iyo yekupisa coil idanho-kumusoro shanduko ine 2 mhepo - yakaderera-voltage uye yakakwira-voltage, kana autotransformer mune iyo ese ari maviri mavhiri ane akafanana kutaurirana, akasarudzwa "K" (muviri). Iyo yekutanga yekumhanyisa inovadzwa neine varnished tambo yemhangura yakakura dhayamita 0,53-0,86 mm uye ine 100-200 kutendeuka. Yechipiri yekumhanyisa inoremerwa netambo ine dhayamita ye0,07-0,085 mm uye ine zviuru makumi maviri - makumi matatu zvemazana.
Kana injini ichimhanya uye iyo camshaft ichitenderera, iyo cam michina yemugovera inoteedzana ichivhara uye kuvhura iwo mafonicha, uye panguva yekuvhura, izvozvi zvichichinja mukutanga kutenderera kweiyo kuvesa coil zvinoenderana nemutemo wemagetsi emagetsi induction inokonzeresa yakakwira voltage.
Muchirongwa chakafanana, icho chakashandiswa kusvika kuma90s, magetsi emudunhu rekuvhura aigara achipisa, uye mumakore ekupedzisira makumi maviri nemakumi matatu, vagadziri vezvigadzirwa zvemagetsi vakatsiva mabhureki emuchina nematanho akavimbika, uye mumotokari dzazvino, mashandiro yecoil yekubatidza inodzorwa neinjini yekudzora yuniti, mune mune yakavakirwa-mukati switch.
Dzimwe nguva switch yacho inosanganisirwa neiyo coil yekuvesa, uye kana ikakundikana, unofanirwa kushandura switch pamwe chete necoil.
Magadzirirwo ecoil mhando
Iko kune angangoita mana marudzi emoto mairi anoshandiswa mumotokari:
- zvakajairika kune iyo yose kuvesa system;
- akajairika mapatya (e4-humburumbira injini);
- general katatu (ye6-humburumbira injini);
- yakasarudzika pane imwe humburumbira, yakapetwa kaviri.
Iwo akajairika mapatya uye matatu mako panguva imwe chete anogadzira marambi mumasirinda anoshanda muchikamu chimwe chete.
Kuongorora hutano hwecoil yekuvesa ine multimeter
Kutanga kutarisa koil yekuvesa ne "kuenderera" kwayo, kureva. kuyera kushorwa kwetambo mhepo.
Kutarisa kwakajairika kuvesa coils
Kuongorora iyo coil kunofanira kutanga neyayo yekutanga kumhanyisa. Iyo yekumisikidza kuramba, nekuda kweiyo diki nhamba yekutendeuka kwetambo gobvu, zvakare yakaderera, mune yakatambanuka kubva ku0,2 kusvika ku3 Ohm, zvinoenderana neyeiyo coil modhi, uye inoyerwa mune multimeter switch chinzvimbo "200 Ohm".
Iko kukosha kwekudzivirira kunoyerwa pakati pezviteshi "+" uye "K" zvecoil. Mushure mekudaidza vanofambidzana "+" uye "K", iwe unofanirwa kuyera kushorwa kweiyo yepamusoro-voltage coil (iyo switch yemultimeter inofanira kuchinjirwa kune "20 kOhm" chinzvimbo) pakati pezviteshi "K" uye kubuda kweiyo yepamusoro-voltage waya.
Kuti uite kusangana neiyo yepamusoro-voltage terminal, bata iyo multimeter probe kune yemhangura kusangana mukati meiyo yepamusoro-voltage waya yekubatanidza niche. Kuramba kweiyo yepamusoro-voltage ichitenderera inofanira kunge iri mukati me2-3 kOhm.
Iko kutsauka kwakakosha kwekushomeka kwechero ipi yecoil windings kubva kune chaiyo (mune yakanyanyisa kesi, dunhu pfupi kana yakavhurika redunhu) inoratidza zvakajeka kushanda kwayo uye kudiwa kwekuitsiva.
Kutarisa mairi maviri emagetsi
Kuyedza hunyambiri hwekubatidza ma coils kwakasiyana uye zvakati omei. Mune aya ma coils, iyo inotungamira yeiyo yekutanga kumhanyisa inowanzo kuburitswa kune iyo pini yekubatanidza, uye nekuenderera kwayo, iwe unofanirwa kuziva kuti ndeapi mapini echisungo ayo akabatana.
Kune maviri akakwira-magetsi zviteshi zveaya makoiri, uye yechipiri ichitenderera inofanirwa kukosheswa nekubata ma multimeter probes neese maviri-emagetsi matemu, nepo kuramba kunoyerwa nemultimeter kungave kuri kwakati pfuurei kupfuura kweiyo coil inowanikwa kune ese system, uye pfuura 4 kΩ.
Kuongorora wega oisi kupisa
Chikonzero chekushayikwa kwesaraki neicho chiyeuchidzo coils, kuwedzera kukundikana kwoiri pachayo (inoongororwa nemultimeter sezvakatsanangurwa pamusoro), inogona kunge iri kusashanda kweyekuwedzera kupikisa kwakavakirwa mavari. Iyi resistor inogona kubviswa nyore nyore kubva kune coil, mushure mezvo kuramba kwayo kunofanira kuyerwa ne multimeter. Iyo yakajairika kuramba kukosha inotangira pa 0,5 kΩ kusvika kune dzinoverengeka kΩ, uye kana iyo multimeter ikaratidza rakavhurika dunhu, iyo resistor inokanganisa uye inofanirwa kutsiviwa, mushure mezvo kanopenya kazhinji.
Vhidhiyo kuraira yekutarisa kuvesa koira
Mibvunzo nemhinduro:
Nzira yekutarisa sei coil yeVAZ ine multimeter? Nokuda kweizvi, coil iri nyore kubvisa. Kupokana kunopimwa pamakona ose ari maviri. Zvichienderana nerudzi rwekoiri, kushamwaridzana kwemhepo kunenge kuri munzvimbo dzakasiyana.
Nzira yekuedza sei coil ne multimeter? Kutanga, iyo probe yakabatanidzwa kune yekutanga mhepo (kupokana mairi kunofanira kunge kuri mukati me 0.5-3.5 ohms). Chiito chakafanana chinoitwa pamwe nechipiri chemhepo.
Ndinogona kutarisa coil yekudzima? Mugaraji, unogona kuzvimiririra kutarisa chete coil yekubatidza ine bhatiri-mhando yekudzima (yakagadzirwa kugadzirwa). Makoiri emazuva ano anotariswa chete pasevhisi yemotokari.
