Kazhinji, iyo engineering logic yemafuta mhinduro yekudzora system inoona kuti iyo okisijeni sensor iri padyo nekamuri yekupisa, uye iyo yakakwirira kurongeka kwekutonga kwemafuta ndiko, iyo inonyanya kutariswa nehunhu hwekuyerera kwemhepo, sekumhanya kwegasi, kureba kwechiteshi (gasi yakanyanyisa kusara shure pakarepo) uye nguva yekupindura ye sensor, nezvimwewo. Vazhinji vanogadzira vanoisa okisijeni sensor pasi pese manifold ekubuda kwecylinder imwe neimwe, kuitira kuti ione kuti cylinder ine dambudziko, iyo inobvisa mukana wekukanganisa kuongororwa, uye kazhinji inoderedza nguva yekuongororwa nekubvisa inosvika hafu yemasilinda anogona kunetsa. Yakajairika catalytic inoshandura ine huviri hweokisijeni sensor uye yemafuta mhinduro yekudzora sisitimu iyo inowanzo kudzora iyo mafuta ekugovera system inogona kuve yakachengeteka yakachengeteka shanduko yezvinokuvadza ekubuditsa zvinhu kuita isingakuvadze kabhoni oxide uye mhute yemvura. Nekudaro, iyo catalytic inoshandura ichave yakakuvadzwa nekuda kwekupisa (nekuda kwekushomeka kwemoto, nezvimwewo), izvo zvinozotungamira mukuderedzwa kweiyo catalyst pamusoro uye sintering ye orifice metal, izvo zvese zvinokuvadza zvachose iyo catalytic inoshandura.

Kana iyo catalyst ikakundikana, tinogona kuziva kuti matekiniki akakosha mukugadzirisa zvakatipoteredza uye exhaust system.

Kuonekwa kweOBD-II diagnostic system inoita iyo on-board monitoring system uye OBD-II yekutarisa sisitimu yezvakatipoteredza uye catalyst chaiyo yekuona zvinoreva zvinoenderana neiyo oxidation maitiro ezvakanaka kana zvakaipa zvinokonzeresa. Mukushanda kwakadzikama, kushanduka kwechiratidzo cheyakanaka okisijeni sensor (inopisa) kuseri kweiyo catalyst kunofanirwa kunge kuri kushoma pane iyo chero yeokisijeni sensor pamberi peiyo catalyst, nekuti iyo inowanzo shanda catalyst inoshandisa oxidation simba painoshandura hydrocarbons uye kabhoni monoxide, iyo. inoderedza kushanduka kwechiratidzo cheiyo post-oxygen sensor.
