Lambda sensor, inozivikanwawo seokisijeni sensor kana λ-sensor, imhando yezita rekunzwa ratinogona kunzwa kazhinji.Inogona kuonekwa kubva pazita kuti basa rayo rinoenderana ne "oxygen content".Kune kazhinji kaviri masensa eokisijeni, imwe kuseri kwepombi yekuburitsa uye imwe kuseri kwenzira nhatu inoshandura inoshandura.Iyo yekutanga inodaidzwa kumberi kweokisijeni sensor, uye iyo yekupedzisira inonzi rear oxygen sensor.
Iyo okisijeni sensor inosarudza kana mafuta ari kupisa zvakajairika nekuona iyo okisijeni yemukati muhurongwa.Yayo yekuona mhedzisiro inopa iyo ECU data yakakosha yekudzora injini yemhepo-mafuta reshiyo.
Basa reokisijeni sensor
Kuti uwane huwandu hwakanyanya hwekuchenesa gasi uye kuderedza (CO) carbon monoxide, (HC) hydrocarbon uye (NOx) nitrogen oxide zvikamu mumhepo, motokari dzeEFI dzinofanira kushandisa nzira nhatu-catalyst.Asi kuti ugone kushandisa nzira nhatu-catalytic converter zvinobudirira, chiyero chemhepo-mafuta chinofanira kunyatsodzorwa kuitira kuti chigare chiri pedyo nekukosha kwedzidziso.Iyo catalytic converter inowanzoiswa pakati pe exhaust manifold uye muffler.Iyo okisijeni sensor ine hunhu hwekuti kubuda kwayo kwemagetsi kune kushanduka kamwe kamwe munharaunda ye theoretical air-fuel ratio (14.7: 1).Iyi ficha inoshandiswa kuona kuwanda kweokisijeni mukubuda uye kuidzosera kumakombuta kudzora huwandu hwemafuta emhepo.Kana iyo chaiyo yemhepo-mafuta reshiyo inova yakakwirira, kuwanda kweokisijeni mumhepo inopera kunowedzera uye iyo okisijeni sensor inozivisa ECU yekuonda mamiriro emusanganiswa (diki electromotive simba: 0 volts).Apo chiyero chemhepo-mafuta chakaderera kudarika theoretical air-fuel ratio, kusanganiswa kweokisijeni mumhepo inopera inoderera, uye chimiro cheokisijeni sensor inoziviswa kukombiyuta (ECU).
Iyo ECU inotonga kana chiyero chemhepo-mafuta chakaderera kana chakakwira zvichienderana nemusiyano musimba re electromotive kubva kuokisijeni sensor, uye inodzora nguva yejekiseni remafuta zvinoenderana.Nekudaro, kana iyo sensor yeokisijeni inokanganisa uye simba remagetsi rinobuda risiri iro, komputa ye (ECU) haigone kunyatso kudzora reshiyo yemafuta emhepo.Naizvozvo, iyo okisijeni sensor inogona zvakare kutsiva kukanganisa kweiyo air-mafuta ratio inokonzerwa nekupfeka kwezvimwe zvikamu zvemakanika uye zvemagetsi jekiseni system.Zvinogona kutaurwa kuti ndiyo chete "smart" sensor muEFI system.
Basa re sensor ndere kuona kana okisijeni iri mukupopota mushure mekupiswa kweinjini yakawandisa, kureva, iyo okisijeni yemukati, uye iyo okisijeni yemukati inoshandurwa kuita chiratidzo chemagetsi kune injini komputa, kuti injini igone kuona. iyo yakavharwa-loop control ine yakawandisa mhepo chinhu sechinangwa.Iyo mitatu-nzira inoshandura inoshandura ine hukuru hwekushandura hunoshanda kune zvitatu zvinosvibisa zvemahydrocarbons (HC), kabhoni monoxide (CO) uye nitrogen oxides (NOX) mugasi rekubuda, uye inowedzera shanduko uye kucheneswa kwezvinosvibisa zvinoburitsa.
Chii chinoitika kana sensor ye lambda ikatadza?
Kukundikana kweokisijeni sensor uye mutsara wayo wekubatanidza hakuzongokonzeresa kubuda kwakanyanya, asiwo kushatisa mamiriro ekushanda kweinjini, zvichiita kuti mota iratidze zviratidzo senge idling stalls, injini isina kururama, uye madonhwe emagetsi.Kana kukundikana kukaitika, dzinofanirwa kugadziriswa uye kutsiviwa nenguva.
Kumberi kweokisijeni sensor inoshandiswa kugadzirisa kusangana kwegasi rakasanganiswa, uye iyo yekumashure okisijeni sensor ndeyekutarisa mamiriro ekushanda eiyo nzira nhatu inoshandura inoshandura.Iko kukanganiswa kweiyo kumberi kweokisijeni sensor kutadza pamotokari ndeyekuti musanganiswa haugone kugadziriswa, izvo zvichaita kuti mafuta emotokari awedzere uye simba ridonhe.
Ipapo kukundikana kweokisijeni kunoreva kuti mamiriro ekushanda etatu-nzira catalysis haigoni kutongwa.Kana imwe nzira yetatu-catalysis ikakundikana, haigoni kugadziriswa munguva, iyo inozopedzisira yakanganisa mamiriro ekushanda kwejini.
Ndekupi kwekudyara mu lambda sensor?
YASEN, semutungamiri anotungamira wekugadzira sensor yemotokari muChina, tanga tichipa basa rehunyanzvi uye zvigadzirwa zvemhando yepamusoro nevatengi.Kana uchidawholesale lambda sensor, kugamuchirwa kuti utaure nesu kuburikidzasales1@yasenparts.com.
