Basa reiyo post-oxygen sensor.
Basa re sensor ndeyekuona kana paine okisijeni yakawandisa mumhepo yekuburitsa gasi reinjini mushure mekutsva, kureva, iyo okisijeni yemukati, uye shandura iyo okisijeni yemukati kuita chiratidzo chevoltage kuti itumire kune injini komputa, kuitira kuti injini. inogona kuwana yakavharwa-loop control ine yakawandisa mhepo chinhu sechinangwa; Ita shuwa kuti matatu-nzira inoshandura inoshandura ine yakanyanya kupinduka inoshanda kune zvitatu zvinosvibisa mu exhaust hydrocarbon (HC), kabhoni monoxide (CO) uye nitrogen oxide (NOX), uye kuwedzera shanduko uye kucheneswa kwezvinosvibisa zvinoburitsa.
Mabasa e sensor ndeaya:
1, iyo huru yeokisijeni sensor inosanganisira yekudziya zirconia chinhu chetsvimbo inopisa, kupisa tsvimbo ne (ECU) kutonga kwekombuta, kana mhepo inotora idiki (kupisa tembiricha yakaderera) kuyerera ikozvino kune inodziya tsvimbo yekudziya sensor, ichigonesa kunyatsoona. oxygen concentration.
2. Mota yakashongedzerwa nemasensa maviri eokisijeni, imwe isati yasvika matatu-nzira inoshandura inoshandura uye imwe mushure. Basa rekumberi nderekuona chiyero chemhepo-mafuta ejini mumamiriro akasiyana ekushanda, uye komputa inogadzirisa huwandu hwejekiseni remafuta uye inoverengera nguva yekudzima zvinoenderana nechiratidzo. Chinhu chikuru kumashure ndechekuona basa retatu-nzira catalytic converter! Ndiko kuti, chiyero chekushandura che catalyst. Nokuenzanisa nedhata yekumberi kweokisijeni sensor, ihwo hwaro hwakakosha kuona kana matatu-nzira catalytic converter inoshanda zvakajairika (yakanaka kana yakaipa).
Chii chinoitwa neokisijeni sensor yakaputsika kumota?
01 Kuwedzera kushandiswa kwemafuta
Kukuvadza kumusana weokisijeni sensor kunoguma nekuwedzera kushandiswa kwemafuta. Izvi zvinodaro nekuti kabhoni deposition pane okisijeni sensor inogona kutungamira kune isina kujairika chiratidzo kubuda, izvo zvinozokanganisa chiyero chekusanganiswa chejini, ichiita kuti ive isina kuenzana. Kana chiyero chemusanganiswa cheinjini chisina kuenzana, kuitira kuchengetedza kupisa kwakajairika, injini inodzora jekiseni rakawanda remafuta, zvichikonzera musanganiswa wakawandisa, izvo zvinowedzera kushandiswa kwemafuta. Mukuwedzera, nekuda kwekukundikana kweokisijeni sensor, ruzivo rusina kururama runoparidzirwa runogona kuita kuti injini yeokisijeni iwedzere, iyo inowedzera kutungamirira kuwedzera kushandiswa kwemafuta. Naizvozvo, kana iyo okisijeni sensor yakuvadzwa, inofanirwa kutsiviwa nenguva kuti irege kuwedzera kushandiswa kwemafuta.
02 Kubuda kwetsvina kunowedzera
Kukuvadzwa kweiyo okisijeni sensor yekumashure kunozokonzera kubuda kwakawandisa kwemotokari. Izvi zvinodaro nekuti iyo post-oxygen sensor chikamu chakakosha cheyakajairika mashandiro eiyo nzira nhatu inoshandura inoshandura. Kana iyo post-oxygen sensor ikakundikana, iyo nzira nhatu-catalytic converter haigone kushanda nemazvo, saka haigone kunyatso shandura zvinokuvadza kuita zvinhu zvisingakuvadzi. Nenzira iyi, mota inoburitsa zvinosvibisa zvakanyanya panguva yekutyaira, zvichikonzera kubuda kwakawandisa kwemhepo.
03 Kurumidza zvishoma nezvishoma
Kukuvadzwa kuseri kweokisijeni sensor kuchaita kuti mota idzike. Izvi zvinodaro nekuti iyo afteroxygen sensor ine basa rekutarisa huwandu hweokisijeni inoburitswa neinjini uye kupfuudza ruzivo urwu kune yemotokari control system. Kana iyo afteroxygen sensor yakakuvadzwa, kombiyuta yemotokari haigoni kunyatsowana iyi data yakakosha, kuitira kuti injini isingagoni kunyatsogadziriswa uye kugadziriswa. Izvi zvinogona kutungamira mukuderedzwa kwekupisa kweinjini, izvo zvinokanganisa kukurumidza kuita kwemotokari, zvichiita kuti inonoke.
04 Injini yekutadza mwenje ichabatidzwa
Mushure mekunge iyo okisijeni sensor yakuvadzwa, injini yekutadza mwenje inovhenekera. Izvi zvinodaro nekuti iyo afteroxygen sensor ine basa rekutarisa iyo oxygen yemukati inoburitswa neinjini uye kuendesa iyo data kumotokari yemagetsi control system. Kana iyo afteroxygen sensor yakakuvadzwa, haigoni kunyatsopa idzi data, zvichiita kuti electronic control system haigone kutonga zvakarurama kushanda kwejini. Muchiitiko ichi, yemagetsi kudzora hurongwa achafunga kuti pane zvinobvira injini kukundikana, saka injini kukundikana chiedza kunyevera mutyairi.
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
