I-Howo yokulahla iloli elawulwa nge-elekthronikhi umjovo kaphethiloli wenjini iyinjini ye-Ecu ngokusho kwenzwa bese ushintsha amasignali ngokubala okunembile kanye namasignali okulawula okukhiphayo ukuze ulawule umjovo, ngakho enye yezinzuzo zenjini elawulwa nge-elekthronikhi ukusetshenziswa kukaphethiloli okuphansi.Izimbangela zokusetshenziswa kukaphethiloli yilezi: iphutha lenzwa noma isignali yokushintsha, ukucindezela kukaphethiloli okweqile noma ukwehluleka komjovo, ukwehluleka kwesistimu yokuthungela, ukwehluleka kwengxenye yenjini.
1) Thola ukuthi ingabe iphutha liwukusetshenziswa kakhulu kukaphethiloli okubangelwa ukungasebenzi kwenjini.Imikhuba yokushayela engemihle yomshayeli, ingcindezi yamathayi iphansi kakhulu, umthwalo wemoto mkhulu kakhulu, ukudonsa amabhuleki, ukushelela komugqa, ukudluliswa kwe-othomathikhi akukwazi ukuthuthukiswa kube igiya eliphezulu, isiguquli se-torque ngaphandle kokukhiya, njll. kuzoholela ekusebenziseni uphethiloli ngokweqile.
2)Hlola ukuthi injini iseyizimo zephutha ezisobala, njengentuthu emnyama, ukungabi namandla, ukusheshisa okungekuhle.Noma yimaphi amaphutha abangela amandla anganele, ingxube ewugqinsi kakhulu, kanye nezinga lokushisa eliphansi kakhulu lokupholisa kuzoholela ekusetshenzisweni kukaphethiloli wenjini ngokweqile.Isivinini esiphezulu sokungenzi lutho kwenjini singesinye sezizathu zokusebenzisa uphethiloli ngokweqile.Ingxube ewugqinsi ngeke iholele ekulahlekelweni kwamandla, ngokuphambene nalokho, amandla angase akhuphuke kancane, kodwa ingxube yenjini yeloli ye-Howo ayiyona ingxube ewugqinsi kakhulu ayibucayi kakhulu, abanye abantu kunzima ukuyibona, ngaphandle uma iminyene kakhulu kuze kube seqophelweni. ukuthi intuthu yokukhipha.Ukuze uhlole ukuthi ingxube iminyene kakhulu, kungcono ukusebenzisa i-exhaust gas analyzer.Kunjalo, ukuqaqa i-spark plug nakho kuyindlela elula nengenzeka.
(3) Okubizwa ngokuthi isici sokulungisa uphethiloli sesikhathi esifushane yizinga lokulungiswa kwekhompyutha yenjini yeloli yokulahla i-Howo ekuhlanganiseni kwengxube elawulwayo.Inzwa ye-oxygen ithola ukuhlangana kwengxube, bese ikhompuyutha inyusa noma yehlise izinga lokulawula umjovo kaphethiloli ukuze iveze indlela yokulungisa i-coefficient.Uma ikhompuyutha ithola ukuthi i-coefficient yokulungisa uphethiloli yesikhathi esifushane ibe nkulu kakhulu noma incane kakhulu isikhathi esithile, izokwandisa noma yehlise i-coefficient yokulungisa uphethiloli yesikhathi eside ngendlela efanele, okubonisa ukuthi ikhompuyutha ibilawula ukusebenza kwenjini. ngokwengxube ecebile noma ezacile isikhathi esithile.Kuleli qophelo, isici sokulungiswa kukaphethiloli sesikhathi esifushane seloli lokulahla i-Howo sibuyela kunani elimaphakathi.
