Yintoni uphawu lweoyile yevalvu yemoto
Iivalvu zeoyile luhlobo lwe-oyile seal, edla ngokwenziwa ngokuhlanganisa umqolo wangaphandle kunye ne-fluororubber kunye. Iisprings eziziqinisayo okanye iingcingo zentsimbi zifakelwa kwindawo engaphantsi kwe-oyile seal ukuze zivale iintonga zesikhokelo sevalvu yenjini.
Ingathintela ioyile yenjini ukuba ingangeni kwimibhobho yokungenisa kunye neyokukhupha umoya, ithintele ukulahleka kweoyile, ithintele umxube wepetroli nomoya kunye nokuvuza kwegesi yokukhupha umoya, kwaye ithintele ioyile yenjini ukuba ingangeni kwigumbi lokutsha. Ngenxa yokuba idibana nepetroli kunye neoyile yenjini kumaqondo obushushu aphezulu, izixhobo ezinokumelana nobushushu obuhle kunye nokumelana neoyile zihlala zi-fluororubber.
Isitywino seoyile yevalvu eyonakeleyo sinokubangela iingxaki ezininzi. Umzekelo, ioyile yenjini ingangena kwisilinda ecaleni kwentonga yesikhokelo sevalvu, ibangele ukuba iidiphozithi zekhabhoni kwiiplagi zentlantsi, imeko yokusebenza yonakale, okanye nokungasebenzi kakuhle, oku kunciphisa amandla enjini. Ukuthambekela kwevalvu kunokukhokelela ekutywinweni kakubi kwesilinda, ukuncipha koxinzelelo lwesilinda, amandla enjini abuthathaka, kunye nokusetyenziswa kweoyile ngokukhawuleza. Ngexesha lokuqhuba umgama omde, injini inokonakala ngenxa yokunqongophala kweoyile.
Ukuba imoto inobunzima bokukhawulezisa okanye ikhupha umsi oluhlaza okwesibhakabhaka, kusenokwenzeka ukuba isitywini seoyile yevalvu sigugile. Zininzi izizathu zokuguga. Izinto zangaphandle ezixutywe ngexesha lokufakelwa, uthuli, ukuhlanganiswa okubi, indlela yokufakela engalunganga, ukucubungula okungalinganiyo, njl. konke oku kunokukhokelela ekuvuzeni. Uxinzelelo olugqithisileyo kwinkqubo yokukhetha lunokubangela ukuluma kwesithuba kunye nomoya oxubene, okukhokelela ekucinezelweni kwe-adiabatic kunye nokutsha kwesitywini. Intshukumo ephindaphindayo ephezulu inokubangela ukuba isitywini sifudumale, kwaye ukugaywa okomileyo kunye nothuli olungqongileyo kunokubangela ukuguguleka okungaqhelekanga kwendandatho yokutywina kunye nokugqwala kwi-groove yokutywina, okuya kuba nefuthe. Ukukhethwa okungafanelekanga kwezinto zokuxhasa ezikhokelayo kuyilo, ukususwa okungafanelekanga kwee-frost pairs, ii-angles zesikhokelo sentambo ezingafanelekanga eziphelweni zebharele yesilinda, i-piston kunye nesilinda, ii-angles zesikhokelo ezingalunganga zokufakelwa kwesitywini, uburhabaxa obungafanelekanga bomphezulu otyibilikayo, i-electroplating engalinganiyo, kunye noburhabaxa obungonelanga bomjelo wokutywina konke oku kunokonakalisa iringi yokutywina. Ukongeza, iingxaki ngemveliso ngokwayo okanye ukuvalwa nokugcinwa okungafanelekanga, kunye nokonakala kunye nokuwohloka kwezinto zokutywina ngenxa yobushushu obuphezulu ngexesha lokuthuthwa, nazo zinokubangela ukuguga.
Ukufakelwa nokutshintshwa kwezitywini zeoyile zevalvu kubandakanya amanyathelo athile. Xa uqhaqha, qala ususe i-camshaft kunye ne-hydraulic tanner. Sebenzisa isikrufu se-spark plug ukususa ii-spark plugs. Lungisa i-piston yesilinda ehambelanayo kwi-dead center ephezulu. Sebenzisa ii-bolts ukufaka isixhobo soxinzelelo lwentwasahlobo kwintloko yesilinda. Qhagamshela i-air compressor. Sebenzisa i-mandrod enemisonto kwaye ucinezele iqhekeza ukuze ucinezele intwasahlobo yevalvu. Susa intwasahlobo. Cofa kancinci isihlalo sentwasahlobo yevalvu. Susa ibhloko yokutshixa ivalvu. Sebenzisa isixhobo ukuze ukhuphe isitywini seoyile yesiqu sevalvu. Xa uyifaka, i-sleeve yeplastiki kufuneka inamathele kwisiqu sevalvu ukuthintela umonakalo kwitywini yeoyile entsha. Faka umaleko weoyile yenjini kancinci emlonyeni wesitywini seoyile. Faka isitywini seoyile kwisixhobo kwaye usityhale kancinci kwisikhokelo sevalvu. Ngaphambi kokufaka iivalvu zokungenisa kunye nokuphuma, sebenzisa umaleko weoyile yenjini kwisiqu sevalvu.
Ukuqukumbela, nangona isitywino seoyile yevalvu sincinci, umsebenzi waso ubalulekile. Xa kuvela ingxaki, kufuneka isonjululwe ngokukhawuleza.
Izinto ezisetyenziswa kwi-valve assembly ziquka iivalvu, izipringi zeevalvu, ii-valve lock clamps, izikhokelo zeevalvu, iiringi zezihlalo zeevalvu, izitywino zesiqu sevalvu, izihlalo zeevalvu, njl.
Iivalvu zizinto ezibalulekileyo ezilawula ukungena kunye nokuphuma komoya, kwaye zahlulwe zibe ngamacandelo amathathu: iintloko zeevalvu, izihlalo zeevalvu, kunye neziqu zeevalvu. Xa kuyilwa intloko yeevalvu ukuba ithwale amandla aveliswa luxinzelelo lokutsha, kuthathelwa ingqalelo ukuphakama kobuso beevalvu. Isiqu sevalvu sisetyenziselwa ukukhokela ngaphakathi kwesikhokelo sevalvu. Ukuze kuthintelwe ukuguguleka, umphezulu ogqunywe nge-chrome uhlala usetyenziswa.
Intwasahlobo yevalvu inoxanduva lokuvala ivalvu ngendlela elawulekayo ukuthintela ukungcangcazela emva kokuba ivalvu itsibile. Ulwakhiwo lwayo oluqhelekileyo luyintwasahlobo yecylindrical elinganayo.
Isikhokelo sevalvu sisetyenziselwa ukuqinisekisa ukuba ivalvu isembindini wesihlalo sevalvu kwaye idlulisele ubushushu entlokweni yesilinda ngesiqu sevalvu. Xa uyifaka, kufuneka kushiywe indawo efanelekileyo.
I-valve lock clamp inoxanduva lokudibanisa isihlalo se-valve spring kunye ne-valve. Yahlulwe ngohlobo lwe-clamping kunye nohlobo lwe-non-clamping. Uhlobo lwe-clamping lufanelekile ngakumbi kwiinjini ezinesantya esiphezulu sokujikeleza.
Isihlalo sevalvu sisebenza ukwahlula igumbi lokutsha kwindlela yegesi. Ubushushu budluliselwa ukusuka kwivalvu ukuya entloko yesilinda ngale ndawo. Ububanzi bomphezulu wayo buhlala buyi-1.2 ukuya kwi-2.0mm. I-Angle iya kuchaphazela isiphumo sokutywina kunye nemeko yokuguguleka.
Ububanzi bentloko yevalvu yokungenisa bubukhulu nge-15% ukuya kwi-30% kunevalvu yokukhupha umoya ukuze kwandiswe umthamo wokungenisa umoya. Iinjini zeemoto zanamhlanje ezisebenza kakuhle zihlala zisebenzisa iivalvu ezintathu, ezine okanye ezintlanu kwisilinda nganye. Phakathi kwazo, iinjini ezineevalvu zisetyenziswa kakhulu, ezinokunyusa umthamo womoya wokungenisa umoya, i-torque kunye namandla, zinciphise amandla angenamsebenzi okunyakaza kwevalvu, kwaye ikakhulu zisebenzisa igumbi lokutsha elinomfanekiso we-marque, elilungele inkqubo yokutsha.
