Luyini uhlelo lomoya lwesibili lwemoto?

Isistimu yomoya yesibili yemoto

Ezinjini zikaphethiloli, ukujova komoya wesibili ohlelweni lokukhipha umoya kuyindlela efakazelwe yokunciphisa ukukhishwa okuyingozi. Ngesikhathi sokubanda kuqala. Kuyaziwa ukuthi injini kaphethiloli ethembekile idinga ingxube ecebile yomoya / kaphethiloli ukuqala okubandayo. Le nhlanganisela iqukethe uphethiloli oweqile. Ngesikhathi sokuqala okubandayo, inani elikhulu le-carbon monoxide nama-hydrocarbon angashiswanga akhiqizwa ukuthungela. Njengoba i-catalyst ingakafiki ekushiseni okusebenzayo, amagesi ayingozi wokukhipha angadedelwa emkhathini. Nciphisa okuqukethwe kwezinto eziyingozi emagesi aqeda amandla ngesikhathi sokuqala kwenjini. Umoya wasemkhathini uhlinzekwa kumaningi wokukhipha endaweni eseduze kwamaphayiphu okukhipha. Kusetshenziswa uhlelo lwesibili lomoya, olubizwa nangokuthi uhlelo olusizayo lokuhambisa umoya.

Ukuhamba komsebenzi

Lokhu kuholela ekwakheni uketshezi okwengeziwe noma ukushisa kwezinto eziyingozi emagesi aqediwe. Ikhiqiza isikhutha esiyingozi namanzi. Ukushisa okwenziwe yile nqubo ngokungeziwe kushisa izinzwa ezi-catalyst nezomoya-mpilo. Lokhu kunciphisa isikhathi sokuqala umsebenzi wabo osebenzayo. Uhlelo lwesibili lomoya selusetshenziselwe izimoto kusukela ngo-1997. Ngenxa yokwenziwa ngcono kohlelo lokujova uphethiloli nohlelo lokuphathwa kwezinjini. Uhlelo lwesibili lokuphakelwa komoya lincipha kancane kancane ngokubaluleka kwalo. Umklamo wesistimu yokuphakela umoya wesibili ufaka iphampu yomoya yesibili, i-valve yomoya yesibili kanye nohlelo lokulawula. Iphampu yomoya yesibili ingumlandeli kagesi oshayelwa ugesi. Umoya wasemkhathini ungena kupompo ngentambo yokuhlunga yomoya.

Umshini valve ukusebenza

Umoya ungadonselwa kupompo ngqo kusuka egumbini lenjini. Kulokhu, ipompo inesihlungi somoya esakhelwe ngaphakathi. Kufakwa i-valve yesibili yokuhambisa umoya phakathi kwepompo yomoya yesibili nobuningi bokukhipha. Ihlanganisa ama-valve wokulawula nokulawula. I-valve engabuyisi ivimbela ukuphuma kwamagesi ekuphumeni nasekunciphiseni kohlelo lokukhipha. Lokhu kuvikela ipompo ekulimaleni kwesibili komoya. I-valve yokuhlola inikeza umoya wesibili ekuqedeni kokukhipha ngesikhathi sokuqala okubandayo. Isevavu yokungenisa umoya yesibili isebenza ngokuhlukile. Umshini, umoya noma ugesi. I-actuator esetshenziswa kakhulu yi-vacuum valve. Isetshenziswa yi-solenoid changeover valve. I-valve nayo ingaqhutshwa ingcindezi. Ikhiqizwa yimpompo yomoya yesibili.

Ukwakhiwa kwesistimu yomoya yesibili

I-valve engcono kakhulu yilena edonsa ngogesi. Inesikhathi esifushane sokusabela futhi imelana nokungcola. Isistimu yomoya yesibili ayinayo isistimu yayo yokulawula. Ifakwe kumjikelezo wokulawula injini. Ama-activator wesistimu yokulawula i-motor relay, iphampu yomoya yesibili kanye ne-vacuum line solenoid changeover valve. Izenzo zokulawula ezindleleni zokushayela zakhiwe ngesisekelo sezimpawu ezivela kuzinzwa ze-oxygen. Izinzwa zokushisa ezipholile, ukugeleza komoya omkhulu, isivinini se-crankshaft. Isistimu icushwa lapho izinga lokushisa elipholile lenjini liphakathi kuka +5 no +33 °C futhi lisebenza imizuzwana eyi-100. Bese iyacisha. Emazingeni okushisa angaphansi kuka +5 °C uhlelo alusebenzi. Uma uqala injini efudumele idling, isistimu ingavulwa kafushane imizuzwana engu-10. Ize injini ifinyelele izinga lokushisa lokusebenza.

Imibuzo nezimpendulo:

Iyini iphampu yomoya yesibili? Lo mshini unikeza umoya omusha ohlelweni lwe-exhaust. Iphampu isetshenziswa ngesikhathi sokuqala okubandayo kwenjini evuthayo yangaphakathi ukuze kuncishiswe ubuthi bokukhipha umoya.

Uyini umoya wesibili? Ngaphezu komoya oyinhloko womkhathi, ezinye izimoto zine-supercharger eyengeziwe enikeza umoya ohlelweni lwe-exhaust ukuze i-catalyst ifudumale ngokushesha.

Iyiphi ingxenye eklanyelwe ukunikeza umoya owengeziwe ekamelweni elivuthayo? Kulokhu, kusetshenziswa ipompo ekhethekile kanye ne-valve yokuhlanganiswa. Zifakwe ku-multifold exhaust eduze ngangokunokwenzeka kuma-valve.
