Inzwa yokugeleza komoya iguqula umoya omunyiwe ube isignali kagesi futhi iyithumele kuyunithi yokulawula kagesi (ECU) njengenye yezimpawu eziyisisekelo zokunquma umjovo kaphethiloli.Ngokwemigomo ehlukene yokulinganisa, ingahlukaniswa ngezinhlobo ezine: inzwa yokugeleza komoya ejikelezayo (i-Toyota PREVIA station wagon), i-Carmen vortex air flow sensor (imoto yeToyota Lexus LS400), inzwa yokugeleza komoya ezinikezele (injini ye-VG30E yeNissan Maxima neVolvo Injini ye-B230F yebhasi yasekhaya i-Tianjin Sanfeng TJ6481AQ4) kanye nenzwa yokugeleza komoya yefilimu eshisayo.Okubili kokuqala kuwuhlobo lokugeleza kwevolumu, kanti ezimbili zokugcina ziwuhlobo lokugeleza okukhulu.Njengamanje, kunezinhlobo ezimbili eziyinhloko zezinzwa zokugeleza komoya: inzwa yokugeleza komoya yomugqa ozinikele kanye nenzwa yefilimu eshisayo yokugeleza komoya.

1. Ukwehluleka kwentambo yamandla ekhompiyutha kuzokwenza ukusebenza kwenjini yezimoto kube kubi kakhulu futhi umnotho wehle, ngakho intambo yamandla ekhompyutha kufanele ihlolwe kuqala ngaphambi kokushintshwa kwekhompyutha yemoto.(Intambo yamandla kufanele ifake intambo yaphansi ukuze ibhekwe njengentambo yamandla ephelele).

2. Uma isignali ye-voltage yenzwa ye-oxygen iphakeme kunevelu evamile, kungenzeka ukuthi inzwa ingcolile, futhi ezimweni eziningi izokwenza isilinganiso se-air-fuel sicebile.

3. Uma isignali ye-voltage yenzwa ye-oxygen iphansi kunevelu elijwayelekile, kungase kube ukuthi inzwa iphumile ekuhlelekeni, okuzoholela esilinganisweni esincane samafutha omoya wenjini.

4, lapho uhlola inzwa ye-oxygen kumele usebenzise i-digital multimeter, noma i-oscilloscope.

5. Uma i-heater yenzwa ye-oxygen inephutha, ingase yelule isikhathi sokusebenza se-open-loop senjini futhi yandise ukusetshenziswa kukaphethiloli.

6. Inzwa yokushisa epholile yenjini ingahlola ukusebenza kwayo ngemitha yedijithali noma imitha ye-analog.

7. Kumjikelezo we-ect wamanye amakhompyutha, i-resistor yangaphakathi izolawulwa ekushiseni okuthile kwenjini ukuze iguqule i-voltage kunzwa.Uma i-voltage ngalesi sikhathi ingavamile ngesikhathi sokulinganisa, akusho ukuthi inzwa inephutha.

8. Inzwa yokushisa epholile yenjini yokuhlola kanye nenzwa yokushisa komoya ingasebenzisa inqubo yokusebenza efanayo ncamashi, kodwa into okumele uyiqaphele ukuthi amajika okushintsha izinga lokushisa ahlukile, ngakho-ke ngeke kube khona isignali ye-voltage efanayo ezingeni lokushisa elifanayo.

9. Uma i-valve ye-throttle ivuliwe futhi isignali ye-voltage ye-throttle position sensor ihlolwe, ukuzinza kwenzwa kungabhekwa ngokudlidliza ngamandla afanele.Le ndlela iphumelela kakhulu kwamanye amaphutha okuxhumeka okubonakalayo kwesifunda.

10. Izinzwa eziningi ezinezintambo ezine ze-throttle position zifaka isishintshi sendawo engenzi lutho, esisetshenziselwa ukunikeza iyunithi yokulawula injini ngolwazi lwesimo sokusebenza senjini lapho i-throttle isendaweni yokungenzi lutho.
