Indima nomthelela we-egr valve

1. Yini i-egr valve

I-egr valve ingumkhiqizo ofakwe kwinjini yedizili ukulawula inani lokuphinda usebenzise i-gesi yokuphinda unikeze uhlelo lokudla. Ngokuvamile kutholakala ohlangothini lwesokunene sokudla okuningana, eduze kwe-throttle, futhi kuxhunywe ngepayipi lensimbi elifushane eliholela ekungeneni kwe-many.

I-egr valve inciphisa izinga lokushisa legumbi lokuvutha ngokuqondisa igesi yokuphelelwa amandla ukuze ubambe iqhaza ekuhlanganiseni, uthuthukise ukusebenza kwenjini, unciphise ukukhishwa kwe-complents, unciphise ukukhishwa kwengxenye yengxenye ngayinye. Igesi yokuphelelwa yimoto yigesi engavuthanga engabandakanyi ekuvukeni egumbini lokuhlanganisa. Kwehlisa izinga lokushisa lokuvutha kanye nengcindezi ngokuthola ingxenye yokushisa ekhiqizwe yi-combustion ukunciphisa inani le-nitrogen oxide ekhiqizwayo.

2. Kwenzani i-eGR valve

Umsebenzi we-EGR valve ukulawula inani legesi yokuphelelwa yigesi okufaka inqwaba many, ukuze inani elithile lemfucuza ligelezela ekunciphiseni okuningi ukuze kuphindeka.

Lapho injini isebenza ngaphansi komthwalo, i-egr valve ivulekile, ifike ngesikhathi, ilungele ingxenye yegesi yokuphelelwa yi-cylinder, ngakho-ke igesi ephumayo ingaba yingxenye yokushisa okukhiqizwayo, ngakho-ke igesi yokushisa ingaba yingxenye yokushisa okukhiqizwayo, ngakho-ke igesi, ngaleyo ndlela inciphise inani lezinhlanganisela ze-nox.

I-3.Effect ye-EGR Valve Card Lag

 Amazinga we-Emion VIenUGine ubeka inzwa yesikhundla noma inzwa yokushisa igesi noma inzwa yokucindezela e-EGR valve ukwenza ukulungiswa okuvaliwe kanye nokulawulwa kwempendulo yenani lokuphindaphindeka kwe-gesi yokuphindaphinda. Ngokusho kwezimo zangempela zokusebenza zenjini kanye nezinguquko zezimo zokusebenza, kungashintsha ngokuzenzakalelayo inani legesi yokuphelelwa amandla ebandakanyeka ekuvuseleleni kabusha.

Uma i-egr valve ejeziswa, inani langempela legesi yokuphelelwa amandla ekungeneni manifold ngeke ingalawuleki.

Ukuphinda usebenzise i-gesi kabusha igesi kuzothinta umsebenzi ojwayelekile wenjini, kube nomthelela omkhulu ekusebenzeni kwenjini, futhi kuthinte umphumela wamandla wenjini, okuholela ekuntuthulweni kwamandla enjini. I-getro kadoti encane kakhulu ekusakazweni izothinta izinga lokushisa legumbi le-enjini yokuhlanganisa, okwandisa ukuphuma kwamakhompiyutha, okuholela ekuphumeni akusona okujwayelekile, okuholele ekutholeni ama-tersonion akhawulelwe enjini.
