Yintoni umsebenzi wemitha yokuhamba komoya emotweni?
Linganisa umthamo womoya ongenayo kwaye ulawule ukufakwa kwepetroli
Umsebenzi ophambili wemitha yokuhamba komoya yesithuthi kukulinganisa ukuhamba komoya okungena enjinini nokuthumela isignali kwiyunithi yolawulo lwe-elektroniki (ECU) ukulawula ngokuchanekileyo umthamo wokufakwa kwamafutha, ngaloo ndlela kuphucula ukusebenza kakuhle komlilo, ukunciphisa ukukhutshwa komoya, kunye nokuphucula ukusebenza kwamandla. Imisebenzi ethile ibandakanya:
- Ukubeka esweni ubungakanani bomoya ongenayo ngexesha langempela: Ngokubona isantya sokuhamba komoya kusetyenziswa i-thermistor okanye i-vortex sensor, ubungakanani obubonakalayo buguqulwa bube sisignali yombane (njengotshintsho lokumelana okanye isignali yefrikhwensi) ukuqinisekisa ukuba i-ECU ifumana idatha echanekileyo.
- Ukulawula umlinganiselo womoya-fuel: I-ECU ilungisa ngokuguquguqukayo umthamo wokufakwa kwefuel ngokusekelwe kwidatha yokuhamba komoya, igcina umlinganiselo ofanelekileyo womoya-fuel (malunga ne-14.7:1), iphephe ukutyeba kakhulu (okubangela ukwakheka kwekhabhoni kunye nokusetyenziswa kwamafutha okwandisiweyo) okanye ukutsha okuncinci kakhulu (okubangela ukulahleka kwamandla).
- Ukuziqhelanisa neemeko zokusebenza ezahlukeneyo: Iphendula ngokukhawuleza (ngaphakathi kwee-milliseconds) ngexesha lokungasebenzi, ukukhawulezisa, okanye ukuhla kwesantya, umzekelo, ukwandisa ukufakwa kwepetroli ukuze kwandiswe amandla ngexesha lokukhawulezisa kunye nokugcina umoya ozinzileyo ukungenisa ukuthintela ukuminza kwenjini ngexesha lokungasebenzi.
Xa imitha yokuhamba komoya kwisithuthi ingasebenzi kakuhle, iimpawu eziphambili ziquka:
- Ukungazinzi okungasebenziyo
- Ukukhawulezisa okubuthathaka
- Ukusetyenziswa kwepetroli okwandisiweyo
- Umsi omnyama ovela kumbhobho wokukhupha umoya
- Ukuma okanye ukungcangcazela kwenjini okungaqhelekanga
- Iimpawu ezithile:
Iimpawu zempazamo engundoqo
Isixhobo sokulinganisa ukuhamba komoya esonakeleyo siya kubangela ukufunyanwa komthamo womoya ongeniswayo ngendlela engaqhelekanga, nto leyo echaphazela ulawulo lokujova ipetroli kwaye ikhokelele kwiingxaki eziqhelekileyo:
- Ukungazinzi kwenjini: Injini iyanyikima ngokubonakalayo xa ingasebenzi okanye ngesantya esiphantsi, kunye nee-RPM eziguquguqukayo, kwaye ide ime (ngenxa yokungakwazi kwe-ECU ukulungisa ngokuchanekileyo umlinganiselo womxube).
- Ukukhawulezisa okubuthathaka: Injini iphendula kancinci xa inyathela i-accelerator, nto leyo eyenza kube nzima ukuyidlula (ingakumbi xa isantya siphezulu, njengaxa isantya sidlula i-120 km/h kwaye i-RPM iyehla).
- Ukonyuka okungaqhelekanga kokusetyenziswa kwepetroli: Ukusetyenziswa kwepetroli kuyanda nge-10%-15%, ngenxa yokubalwa okungachanekanga komthamo wokufakwa kwepetroli, okubangela ukuba ipetroli ityebe kakhulu (kubangele ukwakheka kwekhabhoni kunye nokusetyenziswa kwepetroli okwandisiweyo) okanye ukutsha okuncinci kakhulu (kubangela ukulahleka kwamandla).
- Umsi omnyama ophuma kumbhobho wokukhupha umoya: Ukutsha okungaphelelanga kuvelisa umsi omnyama omninzi, ohamba nongcoliseko olugqithisileyo lokukhupha umoya (ukukhutshwa kwe-HC kungadlula i-500 ppm).
- Ukuma okanye ukushukuma kwenjini okungaqhelekanga: Injini iyashukuma ngequbuliso okanye ima ngexesha lokuqhuba ngesantya esiphezulu, kwaye isebenza ngokuqhelekileyo xa ingasebenzi (ngenxa yokungachaneki kokuphuma kwesignali yesantya esiphezulu).
Ezinye iziphumo ezinxulumene noko
- Isibane sesalathisi sempazamo: Ideshibhodi ikhanyisa isibonisi sempazamo yenjini (esifana nesilumkiso esithi "INJINI YENKONZO").
- Ubunzima bokuqalisa: Kunzima ukuqalisa injini xa iqalisa kubanda ngenxa yokungakwazi kwe-ECU ukulinganisa umlinganiselo ochanekileyo we-air-fuel.
- Umngcipheko womonakalo wexesha elide: Iimpazamo eziqhubekayo zinokwenza injini iguge kakhulu kwaye zinciphise amandla oxinzelelo lwesilinda.
Ukuba ezi mpawu zingasentla ziyenzeka, kuyacetyiswa ukuba zilungiswe ngokukhawuleza ukuze kuthintelwe ukonakalisa izinto ezifana ne-three-way catalytic converter.
Isixhobo sokulinganisa ukuhamba komoya emotweni singacocwa, kodwa kudla ngokufuneka sicocwe kuphela xa singcolile okanye sineengxaki.
Ukucoceka
- Ingacocwa: Xa ikhabhoni okanye ukungcola kuqokelelene kwizinzwa zangaphakathi zemitha yokuhamba komoya, ukucoca kunokubuyisela ukuchaneka kokulinganisa kwayo kwaye kusombulule iingxaki ezinje ngokungabikho kwamandla enjini kunye nokusetyenziswa kwepetroli okwandisiweyo.
- Akunyanzelekanga: Kwisithuthi esigcinwe kakuhle, imitha yokuhamba komoya idla ngokucoceka kwaye ayifuni kucocwa rhoqo.
Iindlela zokucoca kunye namanyathelo okhuseleko
- Indawo kunye nokuqhaqha: Imitha yokuhamba komoya idla ngokuba kwindawo yokuhluza umoya emva kombhobho wokungenisa umoya. Ukuqhaqha kufuna ukusetyenziswa kwezixhobo zobungcali ukunqanda umonakalo.
- Umsebenzi wokucoca:
- Ukucoca ngaphandle: Sebenzisa ilaphu elingalukwanga elifakwe kwi-alcohol ukuze usule amabala eoyile kwikhabhathi.
- Izinzwa zangaphakathi: Sebenzisa izicoci zekotoni ezifakwe kwi-95% okanye ngaphezulu kotywala okanye iiarhente zokucoca ze-elektroniki ezinikezelweyo ukuze usule ngobunono izinzwa zeplatinum wire/thermistor. Musa ukusebenzisa iiarhente zokucoca ezibolayo (ezifana neearhente zokucoca iikhaburetha).
- Ukucoca igridi: Sebenzisa ibrashi ethambileyo ukucoca ukungcola okukwigridi.
- Ukomisa nokufaka kwakhona: Sebenzisa isixhobo sokomisa iinwele ukuze womise kakuhle izinto ezisetyenzisiweyo, uqinisekise ukuba zomile ngokupheleleyo ngaphambi kokuba uzifake kwakhona, kwaye unikele ingqalelo ekuqiniseni uqhagamshelo lwentambo.
- Iinkcukacha zobugcisa:
- Ukukhetha iiarhente zokucoca: Kuphela ziiarhente zokucoca ze-elektroniki eziguquguqukayo okanye i-anhydrous ethanol (uxinzelelo ≥ 95%) ezivumelekileyo. Zisebenze ngobunono: Izixhobo zesensor zithambile. Amandla okusula kufuneka abe lula ukuze kuthintelwe umonakalo.
Emva kokufakela, jonga: Emva kokucoca, qalisa injini kwaye ujonge imeko yokusebenza. Ukuba kuvela ikhowudi yempazamo, yenza i-ECU adaptive learning.
