Main application

1.Kuitira kuwana chiyero chekuchenesa gasi chakakwirira uye kuderedza zvikamu zve (CO) carbon monoxide, (HC) hydrocarbons uye (NOx) nitrogen oxides mumhepo inopedza gasi, motokari dzeEFI dzinofanira kushandisa nzira nhatu-catalytic converters.Zvisinei, kuti unyatsoshandisa nzira nhatu-catalytic converter, zvinodikanwa kunyatso kudzora chiyero chemhepo-mafuta kuitira kuti igare iri pedyo neyo theoretical air-fuel ratio.Iyo catalyst inowanzoiswa pakati pe exhaust manifold uye muffler.Iyo okisijeni sensor ine hunhu hwekuti yakabuda voltage inongoerekana yachinja padyo neiyo theoretical air-fuel ratio (14.7: 1).Hunhu uhu hunoshandiswa kuona kuwanda kweokisijeni mugasi rekuburitsa uye kuidzosera kumakombuta kudzora huwandu hwemafuta emhepo.Kana iyo chaiyo yemhepo-mafuta reshiyo inova yakakwirira, kuwanda kweokisijeni mumhepo yekuburitsa gasi kunowedzera uye sensor yeokisijeni inozivisa ECU yemamiriro akaonda emusanganiswa (small electromotive force: O volts).Kana chiyero chemhepo-mafuta chakaderera pane theoretical air-fuel ratio, kuwanda kweokisijeni mumhepo inopera inoderera, uye mamiriro eiyo okisijeni sensor (huru electromotive simba: 1 volt) inoziviswa kune ECU komputa.

2.ECU inotonga kana chiyero chemhepo-mafuta chakaderera kana chakakwirira maererano ne electromotive simba kusiyana kubva kuokisijeni sensor, uye inodzora nguva yejekiseni yemafuta maererano.Nekudaro, kana iyo okisijeni inofambisa ichikanganisa uye simba remagetsi rinobuda risina kujairika, komputa yeECU haigone kunyatso kudzora reshiyo yemafuta emhepo.Naizvozvo, iyo okisijeni sensor inogona zvakare kugadzirisa iko kukanganisa kwemhepo-mafuta ratio inokonzerwa nekupfeka kwemichina uye zvimwe zvikamu zveEFI system.Zvinogona kutaurwa kuti ndiyo chete "yakangwara" sensor muEFI system.

3.Basa re sensor ndeyekuona kana kune okisijeni yakawandisa mumhepo yekubuda yeinjini mushure mekutsva, ndiko kuti, iyo okisijeni yemukati, uye shandura iyo okisijeni yemukati muchiratidzo chemagetsi uye kuiendesa kune injini komputa, saka. kuti injini inogona kuona yakavharwa-loop control ine yakawandisa mhepo chinhu sechinangwa;Ita shuwa kuti matatu-nzira inoshandura inoshandura ine yakanyanya kupinduka inoshanda yemahydrocarbons (HC), kabhoni monoxide (CO) uye nitrogen oxides (NOX) mumhepo yekuburitsa gasi, uye shandura nekuchenesa zvakasvibiswa zvinosvibisa zvakanyanya.

Kushandisa sumo

Oxygen sensors inoshandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, marasha, simbi, kugadzira mapepa, kudzivirira moto, manejimendi manejimendi, mushonga, mota, gasi emission monitoring uye mamwe maindasitiri.
