Hlola izizathu zokuthi kungani ikhava yegumbi le-valve idinga ukushintshwa!
Isembozo segumbi le-valve yenjini singashintshwa ngaphandle kokuthi siguqukile noma siphukile ekushiseni okuphezulu, noma ucingo olushelelayo lukhululeka ngokuzenzakalelayo futhi luguqukile noma ama-carbon deposits anzima, futhi sidinga ukushintshwa uma kunzima ukususa. I-gasket yesembozo segumbi le-valve isetshenziswa kakhulu ukuvala ukuvimbela ukuvuza kukawoyela.
Ngenxa yokuthi izinto zephedi yesembozo segumbi le-valve ikakhulukazi ziyirabha, akunakugwenywa ukuthi ukuguga nokuqina kuzokwenzeka isikhathi eside, ngakho-ke kuzoba nokuvuza kwamafutha.
Umonakalo wekhava yegumbi le-valve:
1. Ngemva kokuba iphedi yesembozo segumbi le-valve ivuza uwoyela, ungabona iminonjana eminingi yamafutha enjini phezulu kwenjini eduze kohlangothi. Lokhu kungenxa yezizathu ezimbili;
2. Okokuqala, i-valve chamber cover pad iyaguga futhi iyabhidlika, ilahlekelwa ikhono lokuvala futhi ithinta ukuvuza kukawoyela. Ngicabanga ukuthi lesi simo silungile, vele uvule ikhava ye-valve chamber bese ushintsha i-valves chamber.
3, okwesibili ukuthi i-valve ye-PCV yesistimu yokungenisa umoya ye-crankcase ivaliwe, okubangela ukucindezela okuphezulu kakhulu emshinini, okugcina kuthinte ukuvuza kukawoyela wenjini ngaphansi kwengcindezi. Uma le nkinga ingatholakali, izoholela enkingeni enkulu, njengokuvuza kukawoyela we-crankshaft oil seal nokunye;
Ngokuvamile kunzima ukuvimbela ukuvuza kwamafutha kusengaphambili, isizathu esiyinhloko sokuvuza kwamafutha ngokuvamile sibangelwa ukuguga kwe-gasket yenjini, okudinga umnikazi ukuthi anake, ngokuvamile iminyaka engu-3-4 yemoto akuyona into embi kakhulu yokuvuza kwamafutha, kungenzeka ukuthi iningi lezinto ezibangela ukuvuza kwamafutha, uma i-chassis yemoto itholakala inento ebangela ukuvuza kwamafutha, kusho ukuthi isimo sokuvuza kwamafutha sibe sibi kakhulu.
Umkhuba wokuvuza uwoyela ojwayelekile awulula ukuwuthola kumnikazi, empeleni, njalo lapho umnikazi eya endaweni yokuwasha izimoto, vula isembozo sangaphambili ukuze uhlole injini, uma injini itholakala kuyiphi ingxenye yodaka, kusho ukuthi kungase kube nokuvuza uwoyela kule ndawo.
Kodwa amamodeli ahlukene ezingxenye zephutha awafani, kunezindawo eziningi ezingalindelekile ezingase zivele futhi isimo sokuvuza kwamafutha, empeleni, ukuvuza kwamafutha akukubi kangako, ukwesaba ukwesaba enjinini kungagcotshwa ngokugcwele, vele, ngaphezu kwesimo sokuvuza kwamafutha, kunezinjini eziningi futhi ezikhona isimo sokusha kwamafutha, kodwa yisiphi isimo esingesihle.
