TheN0x sensorndechimwe chezvinhu zvakakosha zvakanyanya mumashure ekurapa system.Munguva yekushanda kwejini, iyo N0x yekuisa mumhepo yekupedza gasi yepombi yekupedza injini inogara ichionekwa, kuitira kuti ione kana iyo N0x inobuda inosangana nezvinodiwa zvekutonga.
Iyo N0x sensor chikamu chakapedzwa chinosanganisira induction probe, control module uye wiring harness.Ikoko kune basa rekuzviongorora mukati, uye ruzivo rwekutarisa runoshumwa kuECU kuburikidza neCAN bhazi yekukurukurirana.
1. Kuiswa kwemuviri kwenitrogen oxide sensor:
1. N0x sensorkuisirwa tembiricha zvinodiwa: Kuiswa kweN0x sensor kunofanirwa kungwarira kuti isaiise munzvimbo ine tembiricha yakanyanya.Inokurudzirwa kugara kure nepombi yekupedza uye nepamusoro pebhokisi reSCR, uye nhovo yekupisa nekotoni yekudzivirira inofanira kuiswa panguva yekuisa.Uye ongorora tembiricha yakatenderedza sensor ECU kuisirwa, zvinokurudzirwa kuti iyo yakakwana yekushanda tembiricha yeN0x sensor haifanirwe kunge yakakwira kupfuura 85 madhigirii.
2. Wire harness uye zvinosungirirwa zvekubatanidza zvigadziro: ita basa rakanaka rekugadzirisa uye kudzivirira mvura kwetambo yetambo, chengetedza mutsara wakasununguka panguva yekuisa uye kushandiswa kweN0x sensor, uye iyo yose tambo harness haigoni kukotama zvakanyanya kudzivirira tambo yetambo. kubva pakudonha nekuda kwesimba rakawandisa rekunze kana simba rekuvhunduka, uye edza kudzivirira waya harness uye Iyo N0x sensor inoburitswa.Kana paine waya dzesimbi dziri pachena, dzinofanirwa kuputirwa nematepi zvichiteerana, uye majoini ewaya haafanirwe kukanganiswa nemafuta, marara, madhaka nemamwe magazini, uye kusapinda mvura.Zvikasadaro, sensor ichakundikana nekuda kwemvura mune wiring harness.
2. Chitarisiko cheN0x nitrogen oxide sensor: 2.1 chizvarwa uye 2.8 chizvarwa
1. Iyo NOx sensor ine 12V uye 24V.
2. Iyo NOx sensor ine 4-pin uye 5-pin plugs.
3. Mhando dze nitrogen oxide application modhi dzinoti: Cummins, Weichai, Yuchai, Sinotruk, nezvimwe.
3. Maitiro ekushanda kweiyo nitrogen oxide sensor inotsanangurwa zvakadzama:
Basa guru reN0x sensor ndeyekuona kana kukosha kweN0x mugasi rekubuda kwemhepo kunodarika muganhu, uye kuongorora kana catalytic converter muffler iri kuchembera kana kubviswa.
TheN0x sensorinotaurirana neiyo control unit kuburikidza neCAN bhazi uye ine yayo yekuongorora basa.Mushure mokunge sensor self-checks pasina kukanganisa, chikwata chekutonga chinorayira heater kupisa N0x sensor.Munguva yekupisa, kana chiratidzo che sensor chikasagamuchirwa mushure menguva yekupisa yekupisa yadarika, zvinotemerwa kuti sensor kupisa haina kuvimbika.
1. "Hapana Simba State":
A. Mumamiriro ezvinhu aya, 24V simba haripiwi kune sensor.
B. Iyi ndiyo yakajairika mamiriro e sensor kana switch yekudzima yemuviri yakadzimwa.
C. Panguva ino, sensor haina kubuda.
2. "Powered - sensor isingashande":
A. Panguva ino, simba rave richipihwa kune sensor kuburikidza neiyo ignition switch.
B. Iyo sensor inopinda mu preheating stage.Chinangwa chepreheating ndechekuburitsa hunyoro hwese pamusoro we sensor.
C. The preheating stage will last about 60 seconds.
3. Kana kupisa kwemoto kuchivhurwa, N0x sensor ichapisa kusvika ku100 ° C.
4. Womirira kuti ECM ibudise chiratidzo chetembiricha ye“dova” (Dew point):
Iyo "dova point" tembiricha ndiyo tembiricha iyo pasingazove nehunyoro mune yekuburitsa system inogona kukuvadza iyo N0x sensor.Iyo tembiricha yedova parizvino yakaiswa ku120 ° C, uye kukosha kwekushisa ndiko kukosha kwakayerwa neyekubuda tembiricha sensor yereferenzi EGP.
5. Mushure mekunge sensor inogamuchira chiratidzo chekushisa kwedova kubva kuECM, sensor inodziya pachayo kune imwe tembiricha (yakakura 800 ° C) - Cherechedza: Kana musoro we sensor ukasangana nemvura panguva ino, sensor ichave. kukuvadzwa.
6. Mushure mekupisa kuhutano hwekushanda, sensor inotanga kuyera kazhinji.
7. Iyo nitrogen okisijeni sensor inotumira kuyerwa nitrogen oxide kukosha kuECM kuburikidza neCAN bhazi, uye injini ECM inotarisa nitrogen oxide emission nguva nenguva kuburikidza neruzivo urwu.
4. musimboti wekushanda wenitrogen oxide sensor:
Kushanda musimboti: Chinhu chakakosha che nitrogen uye oxygen sensor ndiyo Zr02 zirconia ceramic chubhu ye ferry, inova yakasimba electrolyte, uye porous platinum (Pt) maelectrodes anoiswa mativi ese.Kana ichipisa kune imwe tembiricha (600-700 ° C), nekuda kwekusiyana kweokisijeni kunyura kumativi ese, zirconia inozosangana nemakemikari reaction, kushaja kufamba kunoitika pamativi ese e electrode, uye iyo inofamba ichaja inoburitsa ikozvino. .Zvichienderana nehukuru hweiyo inogadzirwa ikozvino, iyo oxygen yemukati inotaridzwa, uye iyo oxygen yekusangana inodzoserwa kune controller kuverenga ikozvino nitrogen oxygen concentration uye kuiendesa kuECU kuburikidza neCAN bhazi.
5. sensor probe yekuzvidzivirira basa uye matanho ekuzvidzivirira:
Kana iyo yekubatidza ichibatidzwa, iyo N0x sensor inodziya kusvika ku100 ° C.Womirira kuti DCU itumire chiratidzo che "dova point" tembiricha.Kana iyo sensor inogamuchira chiratidzo chekushisa kwedova inotumirwa neDCU, iyo sensor ichadziya pachayo kune imwe tembiricha (yakakura 800 ° C. Cherechedza: Kana iyo sensor ikasangana nemvura panguva ino, inokonzera kukanganisa sensor)
Dew point kuchengetedza basa: Nekuti iyo nitrogen okisijeni sensor pachayo inoda tembiricha yepamusoro kana electrode ichishanda, iyo nitrogen oxygen sensor ine ceramic chimiro mukati.Iyo ceramic ichaputika kana ikasangana nemvura pakupisa kwakanyanya, saka iyo nitrogen okisijeni sensor ichaisa dova rekudzivirira basa.Basa rebasa iri nderekumirira kwenguva yakati rebei mushure mekuonekwa kwekushisa kwemhepo kunosvika kune imwe tembiricha.Shanduro yekombiyuta inotenda kuti pakupisa kwakanyanya, kunyange kana pane mvura pane sensor mushure menguva yakareba kudaro, inogona kuputirwa nemhepo inopisa inopisa.
6. Rumwe ruzivo rwenitrogen uye oxygen sensor:
Chinhu chinonzi "Gortex"* chinoiswa kune iyoNOx sensorkuve nechokwadi chekuti mweya mutsva unopinda munzvimbo yekuenzanisa yekuenzanisa mukati me sensor.Naizvozvo, zvakakosha kuve nechokwadi chekuti vent iyi haina kuvharwa, uye zvinodikanwa kudzivirira kunze kwenyika kuvharira kana kuvhara vent iyi panguva yekuiswa.Uye zvakare, edza kuve nechokwadi chekuti sensor yakaiswa mushure mekunge muviri wapendwa uye kupendwa.Kana iyo kupenda kwemuviri uye basa rekupenda richifanirwa kuitwa mushure mekunge sensor yaiswa, mavhavha e sensor anofanirwa kuchengetedzwa nemazvo, uye zvinhu zvekudzivirira zvinofanirwa kubviswa mushure mekupenda uye pendi basa rapera kuti ive nechokwadi chekushanda kwakajairika kwe sensor. .
