Nei tichifanira kudzidza iyo clutter chiratidzo pane waveform yeokisijeni sensor?

Izvi zvinodaro nekuti clutter inogona kukonzerwa nekushomeka kwekupisa. Chero bedzi iyo up-flow system isiri mumamiriro ekushanda, iyo catalyst haigone kuongororwa nemazvo. Iyo clutter yeokisijeni sensor waveform inogona kunyevera kuderera kwekuita kweinjini yega yega silinda. Panguva ino, kupera kwegasi kuongororwa ndiyo inonyanya kukosha. Nekuti inogona kuona kuti kushandurwa kweiyo catalyst kunodzikira uye kushanda kwemasilinda ega kunoderera. Clutter masaini zvakare anotadzisa kushanda kwakajairika kwemutongi wemafuta ekudzora mhinduro system (chirongwa chemhinduro mukombuta yekudzora injini inomhanya). "Fuel feedback control system controller" inoreva iyo inoshanda software chirongwa (inonzi "feedback controller"), iri chirongwa chinogashira chiratidzo chemagetsi cheiyo okisijeni sensor uye inoverengera iyo chaiyo yekukurumidza jekiseni remafuta kana musanganiswa wekudzora kuraira. Kazhinji, chirongwa chekutonga chemhinduro hachina kugadzirirwa kubvisa zvinobudirira kuwanda kweiyo okisijeni sensor masaini anogadzirwa nekuda kweabnormal system kushanda uye mirairo yekudzora mafuta. Iyo chaotic high-frequency fluctuation siginecha inogona kuita kuti mutongi wemhinduro atadze kurongeka kana "feedback rhythm". Pane zvakawanda zvinokonzerwa pano. Kutanga, kana kurongeka kwekushanda kwemutongi wemhinduro kunokanganisa, chiyero chemafuta chinosanganiswa chichapfuura hwindo rinokonzera, iro richakanganisa kushanda kwekushanda kwekushandura uye kupera kwemhepo. Chechipiri, kuita kweinjini kuchakanganiswawo. Clutter inogona kuva chiratidzo chakasimba chekuti kunze-kwe-kudzora gasi rekupedza rinopinda mune catalyst. Zvinowanzoonekwa kuti kana clutter iripo, gasi rekupedza rinopinda mu catalyst harina reshiyo yemafuta emhepo. Izvo zvakakosha kuti unzwisise iyo clutter pane waveform yeokisijeni sensor yekugadzirisa uye kuongororwa kwekubuda kwegasi. Mune zvimwe zviitiko, clutter chiratidzo chiri pachena chekuti catalytic shanduko inoshanda yakadzikira, uye ipapo exhaust emission inodarika mwero. Uye zvakare, tsananguro ye clutter pane waveform yeokisijeni sensor chishandiso chakakosha chekuongororwa kweinjini kuita kana kugona kutyaira. Clutter chiratidzo chekusaenzana mukupisa kwesimba kubva kune imwe silinda kuenda kune imwe. Tsananguro uye kunzwisiswa kweiyo clutter pane waveform yeokisijeni transmitter yakakoshawo pakushandisa zvinobudirira kweiyo okisijeni sensor chiratidzo kugadzirisa uye kuonesa. Clutter pane waveform yeokisijeni sensor inoratidza kuti gasi rekupedza rinoshanduka kubva kune imwe cylinder kuenda kune imwe isina kuenzana, kana zvakanyanya kunyanya, yakakwira okisijeni yemukati haiwanikwe kubva kune imwe neimwe nzira yekupisa. Mazhinji masensa eokisijeni anogona kukurumidza kudzoreredza kutsauswa kwevoltiji inogadzirwa neimwe nzira yekupisa kana ichishanda zvakajairwa. Iyo yakakura muganho wechiratidzo che clutter, mukuru musiyano wekuumbwa kweokisijeni inoyerwa kubva mukupisa kwega kwega. Iyo clutter inoonekwa pasi pemhando dzakasiyana dzekutyaira haina kukosha chete kuti uone chikonzero chechikonzero chekutadza kwekudzika-mamiriro uye kwenguva pfupi kuyedza gasi rekupedza simba, asiwo hunoshanda hwaro hwekutonga kwekutyaira. Iyo okisijeni sensor chiratidzo clutter iyo inoumba imwe-kune-imwe exhaust waveform ine peak burr yeBC mune yekumhanyisa modhi chiratidzo chakakosha chekuongorora, nekuti zvinoreva kuti kupisa kuchakundikana pasi pemutoro. Kazhinji, iyo yakakura iyo clutter amplitude. Kune mamwe majekiseni eokisijeni mumhepo inopedza gasi, saka iyo clutter inoratidza kuti avhareji yeokisijeni yegasi remhinduro inopinda mugasi inowedzera kusati kwapera, uye iyo nitrogen oxide mune inokonzeresa haigone kuderedzwa (kemikari) muokisijeni yakapfuma. nharaunda (yakaonda musanganiswa). Kupfupisa, zvinozivikanwa kuti iyo clutter siginecha pane waveform yeokisijeni sensor ine yakajairika mhinduro system haina pesvedzero iri pachena pakupedza gasi kana kuita kweinjini. Chinhu chiduku chiduku chinogona kuregererwa, nepo nhamba huru yehuputi yakakosha. Izvi zvinongoratidza kuti kuongororwa inyanzvi. Kudzidza kutonga izvo zvakajairika uye izvo zvisiri zvinoda kudzidzira, uye mudzidzisi akanakisa ruzivo. Nzira yakanakisa yekudzidza ndeyekutarisa waveform yeokisijeni sensor kubva pakuona akasiyana mileage nemhando dzakasiyana dzemota. Kunzwisisa kuti chii chakajairika clutter uye chii chisina kujairika clutter kwakakosha pakugadzirisa kuburitsa emission uye kutyaira kugona kuongororwa, uye zvakakosha kutora nguva yekudzidza. Kune akawanda akajairika masisitimu, software waveform yakakosha. Kuve neokisijeni sensor referensi waveform yeiyo system iri kudzorwa inogona kuona kuti ndeupi rudzi rwe clutter inotenderwa uye yakajairika, uye rudzii rwe clutter inofanirwa kutariswa. Maitiro ekuita clutter yakanaka ndeaya: kana injini ichiita zvakanaka, hapafanirwe kunge paine vacuum leakage, uye iyo hydrocarbon (HC) makomisheni uye neokisijeni zviri mugasi rekuburitsa zvinowanzoitika. Muchikamu chino chekuedza, ruzivo rwakawanda sezvinobvira ruchapihwa kuitira kuti tinzwisise kuti pane nguva yakakwana uye nzvimbo yekuvhara misoro yese pamusoro peizvi mukudzidziswa uku.
