Izimpawu Zenzwa Enephutha noma Engalungile Yesilinganiso Sesilinganiso Somoya
Okuqukethwe
Uma ubona ukwehla kokusebenza kahle kukaphethiloli noma amandla enjini, kanye nokungenzi lutho, ungase udinge ukushintsha noma yiziphi izinzwa zesilinganiso se-air-fuel.
Inzwa ye-air fuel ratio ingenye yezingxenye ezibalulekile zezinhlelo eziningi zesimanje zokuphatha injini. Izimoto eziningi zizoba nenzwa engaphezu kweyodwa ye-air-fuel ratio. Zifakwe ohlelweni lwe-exhaust ngaphambi nangemva kwesiguquli se-catalytic. Izinzwa zesilinganiso somoya nophethiloli zihlala ziqapha isilinganiso sikaphethiloli womoya wamagesi aphumayo emoto futhi zithumela isignali enembile kukhompuyutha yenjini ukuze ikwazi ukulungisa uphethiloli nesikhathi ngesikhathi sangempela ukuze isebenze kahle kakhulu namandla.
Ngenxa yokuthi izinzwa zesilinganiso sikaphethiloli womoya zidlala indima eqondile ekulungisweni nasekulungiseni injini, zibaluleke kakhulu ekusebenzeni kwayo konke nokusebenza kahle kwenjini futhi kufanele zihlolwe uma izinkinga zenzeka. Imvamisa uma beqala ukuba nezinkinga, imoto ikhombisa izimpawu ezimbalwa ezingazisa umshayeli ukuthi inzwa ye-air-fuel ratio ingase idinge ukunakwa.
1. Ukunciphisa ukusebenza kahle kukaphethiloli
Esinye sezimpawu zokuqala zenkinga yenzwa yesilinganiso somoya-fuel ukwehliswa kokusebenza kahle kukaphethiloli. Inzwa yesilinganiso se-air-fuel iqapha okuqukethwe komoyampilo we-exhaust stream futhi ithumela idatha kukhompuyutha ukuze yengeze noma isuse uphethiloli. Uma kukhona inkinga ngenzwa, ingathumela isignali embi noma engamanga kukhompyutha, engaphazamisa izibalo zayo futhi iphumele ekusetshenzisweni kukaphethiloli ngokweqile. Amamayela ngegalani (MPG) ngokuvamile ehla ngokuhamba kwesikhathi aze abe ngaphansi ngokuqhubekayo kunakudala.
2. Yehlisa amandla enjini.
Olunye uphawu lwenkinga engaba khona ngenzwa yesilinganiso sikaphethiloli womoya ukwehla kokusebenza kwenjini nokuphuma kwamandla. Uma inzwa ye-air-fuel ratio iba "ivila", ngokuhamba kwesikhathi izothumela isignali ebambezelekile kukhompyutha, okuholela ekubambezelekeni okuphelele ekuphenduleni kwayo yonke injini. Imoto ingase ibe nokusabela okuvilaphayo noma okunensayo lapho ijubane, kanye nokulahlekelwa amandla okuphawulekayo nezinga lokusheshisa.
3. Ukungenzi lutho okunzima
Olunye uphawu lwenzwa embi yesilinganiso se-air-fuel ukungenzi lutho. Njengoba izingxube zikaphethiloli womoya ngesivinini esiphansi senjini kumele zishuniswe kahle kakhulu, isignali evela kunzwa yesilinganiso sikagesi womoya ibaluleke kakhulu kwikhwalithi yenjini uma ingenzi lutho. Inzwa ye-oxygen embi noma enesici ingathumela isignali engalungile kukhompuyutha, engakwazi ukuwisa phansi, ibangele ukuthi yehle ngaphansi kwezinga elilungile noma iguquguquke. Ezimweni ezimbi kakhulu, izinga lokungenzi lutho lingawohloka kuze kube yilapho imoto ingase imiswe.
Ngenxa yokuthi isilinganiso sikaphethiloli womoya sidlala indima ebalulekile ekubalweni kwekhompyutha yenjini, kubaluleke kakhulu ekusebenzeni kwayo yonke imoto. Uma usola ukuthi ungase ube nenkinga ngenzwa eyodwa noma ngaphezulu yesilinganiso sikaphethiloli womoya, yiba nochwepheshe oqeqeshiwe, njenge-AvtoTachki, thola imoto bese ushintsha zonke izinzwa zesilinganiso sikaphethiloli womoya uma kunesidingo.
