Volkswagen/Audi EA888 isizukulwana sesibini sesahluli se-oyile-gesi (ivalve yenkunkuma)
Imoto yokuqala yahlulwe yaba ziinguqulelo ezimbini zamandla aphezulu naphantsi
Xa utshintsha, vele utshatise inombolo yemoto yokuqala!
● Imimiselo yokusingqongileyo ifuna ukuba uxinzelelo lwecrankcase lube lubi, oko kukuthi, uxinzelelo olukwi-crankcase kufuneka lubengaphantsi kunoxinzelelo oluqhelekileyo lwe-atmospheric ukuthintela ukuba irhasi yecrankcase ingakhupheli ngqo kwi-atmosfera kwaye ibangele ungcoliseko;
● Ukwahlukana kuphela phakathi kwamandla aphezulu kunye aphantsi yixabiso elibi loxinzelelo, elichongwa ngumthombo woxinzelelo kwi-valve yokukhupha;
● I-Mbar sisithethantonye seemilibar, eyiyunithi yoxinzelelo lomoya. Isentimitha enye yesikwere iphantsi kwe-1 kilogram yoxinzelelo lwe-atmospheric, ebizwa ngokuba yi "1 bar". Iwaka le "bar" libizwa ngokuba yi "millibar". Uxinzelelo oluqhelekileyo lwe-atmospheric lulingana ne-1013 millibar, ngoko ke i-100 millibars iphantse ilingane nesinye kwishumi soxinzelelo oluqhelekileyo lwe-atmospheric;
1. Uguqulelo lwamandla aphezulu
inombolo ye-OE:
06H103495AF=AE=AK=K
Ixabiso elibi loxinzelelo: -100Mbar (millibar)
Ixabiso eliqhelekileyo loxinzelelo olubi kwisantya esingasebenziyo: -115 ukuya -90 mbar
2. Uguqulelo lwamandla aphantsi
inombolo ye-OE:
06H103495AB=AC=AD=AH=AJ=B=H=E
Ixabiso elibi loxinzelelo: -25Mbar (millibar)
Ixabiso eliqhelekileyo loxinzelelo olubi kwisantya esingasebenziyo: -28.5 ukuya -18.5 mbar
● Ukuba ivacuum iphantsi kakhulu, ukuvuza kwecrankcase okanye ukuvuthuza okugqithisileyo kufuneka kuhlolwe;
● Ukuba i-vacuum iphezulu kakhulu, i-diaphragm kunye ne-spring kwivalve yokukhupha kufuneka ihlolwe, okanye ivalve yokukhupha kufuneka itshintshwe ngokuthe ngqo;
★ Amanqaku eempazamo eziqhelekileyo ze-EA888 zesizukulwana sesibini sokukhupha ivalve ye-injini
1. I-diaphragm yevalve elawula uxinzelelo inemingxuma
I-diaphragm yerabha yokuqala emnyama yayilula kakhulu ukuguga kunye nokugqobhoza. Ngoku iphuculwe ibe yi-diaphragm ebomvu ene-fiber mesh eqinisiweyo, engafane ihlupheke kumonakalo;
2. Umngxuma wokukhupha ioyile uvaliwe, nto leyo ebangela ukuba ioyile eyahluliweyo ingabuyeli umva ngokuqhelekileyo
3. Igasket yokutywina iyaguga, nto leyo ekhokelela kwimikhondo yokuvuza kweoyile ngeenxa zonke
★ Malunga nokutshiswa kweoli ye-injini
Oko kubizwa ngokuba "yi-oyile yokutshisa" eneneni ligama eliqhelekileyo elithi "ukusetyenziswa kweoyile okungaphaya komgangatho".
Ezona zizathu ziphambili zokutshisa ioyile EA888:
1. Ivalve olitywina ukuguga kunye nomonakalo
Isitywina seoli yevalve sinemisebenzi emibini:
Enye kukuthintela umxube kwigumbi lokutsha okanye igesi yokuphuma emva kokutsha ekuvuzeni;
Enye kukuthintela i-oyile ye-injini ukuba ingene kwigumbi lokutsha kunye nokuthatha inxaxheba ekutshiseni;
Ke ngoko, xa i-oyile yevalve isitywini esinetywina elibi, iya kubangela ukuba uxinzelelo lwe-cylinder lwehle kunye nengxaki "yokutshisa i-oyile ye-injini".
2. Ukunciphisa ukusebenza kokutywinwa kwamakhonkco episton
Ipiston idla ngokuba nezangqa zomoya ezimbini kunye neringi yeoli enye.
Umsesane womoya usetyenziselwa ukuqinisekisa ukutywinwa phakathi kwe-cylinder kunye nepiston, ngelixa i-oyile ye-oyile isetyenziselwa ukusabalalisa kunye nokukrazula ioli. Xa ipiston ihambela phezulu, ioli ifakwa kudonga lwesilinda, kwaye xa ipiston ihambela ezantsi, i-oyile iyacinywa.
Njengoko i-piston ring inxiba, ukusebenza kwayo kokutywinwa kuya kuncipha kancinci de ioyile ingene kwigumbi lokutsha ukusuka phakathi kweringi yepiston kunye nodonga lwesilinda ukuze ithathe inxaxheba ekutshiseni. Le yintsingiselo yangempela "yeoli evuthayo".
3. I-cylinder eccentric wear okanye ukunxitywa okukhulu
Iringi yepiston (i-oil ring) ayidibani kakuhle nodonga lwesilinda, kwaye i-oyile ye-injini inyukela kwigumbi lokutsha kwaye itshiswe.
4. Sebenzisa i-oyile ye-injini engaphantsi kunye nesihluzo se-oyile
I-oyile ye-injini engaphantsi ayinakubonelela ngokhuseleko olufanelekileyo kwindawo yokukhuhlana, ngoko iya kukhawulezisa ukuguga kwamacandelo e-injini. Oku kubandakanya amakhonkco episton kunye neendonga zesilinda esizazise ngasentla. Ukunxiba okungaqhelekanga kuya kukhawulezisa ukuguga kwe-injini kwaye kubangele ukuba "itshise ioyile" phambi kwexesha.
5. Uxinzelelo lweoli olungaqhelekanga
Xa uxinzelelo lwe-oyile luphezulu kakhulu, luya kubangela ukuba isivalo se-injini sigcwale kakhulu, i-oyile iya kuvuza okanye ingene kwigumbi lokutsha kwaye itshise, oko kukhokelela ekusebenziseni i-oyile ngendlela engaqhelekanga.
Izizathu zoxinzelelo olugqithisileyo lweoyile zibandakanya: isihluzo se-oyile okanye ukuvaleka komjelo weoyile, uxinzelelo olugqithisileyo lokuvula ivalve yokunciphisa uxinzelelo, i-oil viscosity eninzi, njl.
4. I-oil-gas separator (i-valve yokukhupha) ayihlulwe ngokupheleleyo
Xa i-crankcase blowby inkulu kakhulu okanye ivalve yokukhupha ngokwayo ayiphumeleli, umxube we-oyile-gas awukwazi ukwahlukana ngokupheleleyo, obangela ukuba inxalenye yeoli engahlulwanga iziswe kwigumbi lokutsha kwaye itshiswe.
Ngoko ke, ukutshintsha i-valve yokukhupha ayikwazi ukucombulula ngokupheleleyo ingxaki yokutshisa ioli.
Xa isithuthi sitshisa i-oyile, unokujonga kuqala i-vacuum ye-crankcase kunye nokuba ivalve yokukhupha i-exhaust ngokwayo ayilungile. Ukuba ibangelwa yivalve yokukhupha, unokutshintsha ivalve entsha yokukhupha. Ukuba kungenxa yezinye izizathu, kufuneka ubuyisele ezinye izincedisi ezihambelanayo.
