Mota oxygen sensor.
Mota oxygen sensor ndiyo kiyi yekududzira sensor muEFI EFI yekudzora mota
Kune marudzi maviri eokisijeni sensors, zirconia uye titanium dioxide.
Oxygen sensor ndiko kushandisa kweCeramir kusvibisa uye mimwe marara emukati kudzora.
Iyo okisijasi sensor inoshandiswa kuronga zvemagetsi zvekudzora maitiro eiyo jekiseni yekunyora kuti ione
Basa rekushanda
Iyo okisijeni sensor sensor zvakafanana kune bhatiri, ine element zirconia mu sensor ichiita senge elektritte. Iyo yekutanga inoshanda isarudzo ndeyekuti: Pasi pemamwe mamiriro (tembiricha yakanyanya uye platinum catalyn), musiyano wepamhepo pakati nepakati uye kunze kweiyo oo oxide inoshandiswa kugadzira mutsauko ungangoita mutsauko ungangoita mutsauko, zvakanyanya mutsauko. Zviri mukati meokisijeni muMamiriro ekunze ndeye 21%, iyo gasi rekunakisa mushure mekusunganidzwa kwemusanganiswa wekusanganiswa kwemoto.
Pasi peiyo catherys yekushisa kwakanyanya uye platinum, iyo okisijeni yakasungirirwa neoxygen sensor yakadyiwa, saka musiyano weVoltage unogadzirwa, mubatanidzwa wekuburitswa kwemusanganiswa uri padyo ne1v, uye musanganiswa wekusanganiswa Maererano neChiratidzo cheOxygen Sensor, iyo Mhepo-Fuel Ratio inodzorwa kuti igadzirise iyo jekiseni jekiseni yehuswa Iyo okisijeni sensor inogona kungoonekwa zvizere pakupisa kwakanyanya (mugumo unosvika anopfuura 300 ° C) uye inogona kubuda voltage. Inopindura zvakanyanya kukurumidza kuchinja mumusanganiswa panenge mazana masere ° C.
Matipi
Iyo zirconium dioxide oxygen sensor yekuchinja kwekusanganiswa kwemusanganiswa wekusanganisa, uye iyo Titonide dioxide oxygen sensor senser yemusanganiswa unopisa kuburikidza nekuchinja kwekupokana. Iyo yemagetsi control system uchishandisa iyo zirconia sensor isingakwanise kudzora mweya wedenga
Iyo jekiseni vhoriyamu (jekiseni pulse upful)
Kureba-kwenguva refu kururamisa ndiko kukosha kwakatemwa neyunivhesiti yeyunivhesiti yemuchadenga ekushandisa kwe data
Chipo
Kamwe chete okisijeni sensor inokundikana, komputa yemagetsi jekiseni jekiseni haikwanisi kudzora pombi, uye injini ichaita kunge isina kugadzikana yekukurumidza kuita Naizvozvo, mhosva yacho inofanira kubviswa kana kutsiviwa nenzira inguva [1].
Kukanganisa kwehupfu
Oxygen sensor yehupfu inowanzoita uye yakaoma kudzivirira kutadza, kunyanya kushandiswa kwekugara kwemotokari dzinotungamirwa peturu, kunyangwe iyo itsva oxygen sensor, inogona kungoshanda zviuru zvemakiromita mashoma. Kana ichingori chidiki chidiki chepfu, saka uchishandisa tangi yemutobvu-isina gose inobvisa iyo inotungamira pamusoro pechinhu cheokisijeni sensor uye udzorere kune yakajairika kushanda. Nekudaro, kazhinji nekuda kwekunyanyisa kupedzisira tembiricha, kutungamira zvinopinda mukati maro, zvichitadzisa kusarudzika kweokisijeni.
Mukuwedzera, silicon muchetura weokisijeni sensors zvakare chiitiko chakajairika. Kazhinji, Silica yakagadzirwa mushure mekuparadza yeSilicon yaive mumatombo emapeturu, uye gasi reSilicone rakabikwa nesitepines
Kana uchigadzirisa, zvakafanira kusarudza nenzira kwayo uye isa magiramu esimbi uye etc. zvekuti iyo yekuburitsa chiratidzo cheokisijeni sensor iri kunze kwekuenderana. Iyo ecu haigoni kugadzirisa iyo mhepo-mafuta chiyero munguva. Kugadzirwa kweCarbon Deposits kunonyanya kuratidzwa sekuwedzera kwekushandisa mafuta uye kuwedzera kwakakosha mukubuda kwepamhepo. Panguva ino, kana iyo sediment ikabviswa, ichadzokera kune yakajairika basa.
Ceramic kupaza
Iyo ceramic yeokisijeni sensor yakaoma uye brittle, uye kugogodza nezvinhu zvakaoma kana kuputika nemhepo yakasimba inogona kuita kuti zviite kuti zviite uye kutadza. Naizvozvo, zvinodikanwa kuti uve nekunyatso kungwarira kana uchibata nematambudziko uye unatsiva nenguva.
Iyo block waya inopiswa
Iyo Heater Ristance Wire inopiswa. Kune iyo yakacheneswa oxygen sensor sensor, kana iyo heater yekudzivisa waya inopiswa, zvakaoma kuita kuti siteor inosvika kune yakajairika yekuisa tembiricha uye kurasikirwa nebasa rayo.
Mutsara kudzika
Dunhu remukati reOxygen sensor rakabviswa.
Nzira yekuongorora
Heater kupokana kutarisa
Bvisa plug yeiyo okisijeni sensor sensor, uye shandisa multimeter kuyera kupokana pakati peiyo heater pole uye danda yesimbi muokisijeni sensor sensor sensor sensor. Iko kukosha kweanopesana ndeye 4-40ωω (zvinoreva mirairo yeiyo chaiyo modhi). Kana ikasasangana neyakajairwa, dzorera iyo oxygen sensor.
Kuyera kwePeepback Voltage
Paunenge uchiyera iyo mhinduro yeiyo yeOxygen sensor sensor sensor inofanira kunge isingabvumirwe kubva kuyakafeneka yeiyo quicegen sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor sensor senset sentia yeiyo modhiyo yemhando, uye wozopunzika mune harness plug. Iyo yekudyira voltage inogona kuyerwa kubva pamutsara wekutungamira panguva yekuita injini Semuenzaniso, mota dzakateerana dzinogadzirwa neToyota mota Kambani inogona kuyera iyo yekufemera voltage yeiyo okisijeni sensor zvakananga kubva kune iyo lox1 kana ox2 terminals mune mhosva yekuona).
Paunenge uchiyera iyo yekudyira voltage sensor sensor, zvakanakisa kushandisa pointer mhando multimeter ine yakaderera renji (kazhinji 2V) uye kukwikwidzana kwakanyanya (kupokana kwemukati kwakakura kupfuura 10mωω. Nzira dzakanangana dzekuona ndezvekutevera:
1. Shandura injini inopisa kune yakajairika yekushandisa tembiricha (kana kumhanya pa2500r / min mushure mekutanga 2min);
2.. pane iyo wiring harness plug yeiyo oxygen sensor.
3. Mumamiriro ezvinhu akajairika, nekufambira mberi kwekupindura kwekutonga, iyo Foupy voltage yeOxygen sensor icharamba ichichinja pamusoro uye pazasi 0.45V, uye iyo Mhinduro yekufemera inofanira kuchinja isingasviki 8 times
If it is less than 8 times, it means that the oxygen sensor or feedback control system is not working properly, which may be caused by carbon accumulation on the surface of the oxygen sensor, so that the sensitivity is reduced. To this end, the engine should be run at 2500r/min for about 2 minutes to remove carbon deposits on the surface of the oxygen sensor, and then check the feedback voltage. Kana iyo voltmeter pointer ichiri kuchinja zvishoma nezvishoma mushure mekunge kabhoni inogona kubviswa, zvinoratidza kuti iyo okisiGen sensor yakakuvadzwa, kana iyo Computer Dunhu Dunhu Rakashata.
4, oxygen sensor kutaridzika kwemavara kuongorora
Bvisa iyo okisijeni sensor kubva pombi inowedzera uye tarisa kana gomba renyama pane sensor dzimba dzakavharwa uye iyo ceramic core yakakuvadzwa. Kana zvakakanganiswa, dzorera iyo oxygen sensor.
Kukanganisa kunogona zvakare kutsanangurwa nekutarisa ruvara rwepamusoro chikamu cheokisijeni sensor:
1, Light Grey Pamusoro: Iyi ndiyo yakajairika ruvara rweokisijeni sensor;
2, chena yepamusoro: Inokonzerwa neSilicon kusvibiswa, iyo oksijeni sensor inofanira kutsiviwa panguva ino;
3, Brown Pamusoro (sezvakaratidzwa mumufananidzo 1): Inokonzerwa nekutungamira kusvibiswa, kana zvakakomba, zvinofanirwawo kutsiva iyo okisiGen sensor;
.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndokumbira kuti tifonere kana iwe uchida zvigadzirwa zvakadaro.
