Kungani i-valve igoba lapho isikhathi siphukile?
Umshini we-valve usebenza kanje: okwamanje i-piston ifinyelela esikhungweni esiphezulu esifile, ama-valve womabili ekamelweni lokushisa avaliwe - ukucindezela okuthile kwakhiwa kuwo. Ibhande eliphukile kuholela eqinisweni lokuthi valve awunaso isikhathi sokuvala ngesikhathi ngaphambi kokufika kwepiston. ngakho-ke, umhlangano wabo uvela - ukungqubuzana, okuholela ngokuqondile eqinisweni lokuthi i-valve iyagoba. Ngaphambilini, ukuze kuvinjelwe inkinga enjalo, ama-valve grooves akhethekile ayenziwa kuma-ICE amadala. Esizukulwaneni esisha sezinjini ezivuthayo zangaphakathi, ama-recesses afanayo nawo ayatholakala, kodwa ahloselwe kuphela ukugwema ukuguquguquka kwama-valve ngesikhathi sokusebenza kwenjini yangaphakathi yomlilo futhi uma kwenzeka kuphuka ibhande, azilondolozi ngokuphelele.
Ngokombono womzimba, kusukela lapho ibhande lesikhathi liphuka, ama-camshafts ayeka ngokushesha, ngaphansi kwesenzo semithombo yokubuyisela enciphisa amakhamera ayo. Ngalesi sikhathi, i-crankshaft iqhubeka ngokuzenzakalelayo ukunyakaza kwayo okujikelezayo (kungakhathaliseki ukuthi igiya lalibambisene noma cha, ama-revolutions ayephansi noma aphezulu, i-flywheel iyaqhubeka ukuyivula). Okusho ukuthi, ama-piston ayaqhubeka nokusebenza, futhi ngenxa yalokho, ashaya ama-valve avuliwe ngaleso sikhathi. Akuvamile, kodwa kwenzeka lapho ama-valve elimaza i-piston ngokwayo.
Izimbangela zebhande lesikhathi eliphukile
- ukugqokwa kwebhande kanjalo noma izinga layo eliphansi (amagiya e-shaft anemiphetho ebukhali noma ukungena kwamafutha avela ezimpawu zikawoyela).
- ama-crankshaft wedges.
- i-pump wedges (isenzakalo esivame kakhulu).
- ama-camshaft wedges amaningana noma eyodwa (isibonelo, ngenxa yokuwohloka komunye wabo - noma kunjalo, lapha imiphumela ihluke kancane).
- i-tensioning roller ayinqanyuliwe noma ama-roller ahlanganisiwe (kukhona ukuxegiswa noma ukuqinisa ibhande).
Izinjini zanamuhla, njengoba zinamandla kakhulu kunangaphambili, azikwazi ukusinda. Uma sicabangela imbangela, sithembele kuma-valve, le nkinga ibonakala ngenxa yebanga elincane phakathi kwabo ne-piston. Okusho ukuthi, uma ngesikhathi i-piston ifika, i-valve i-ajar, khona-ke igoba ngokushesha. Njengoba ukucindezela okukhulu nokucindezela ngaphansi kwepiston akukho groove ngaphansi kwe-valve yokujula okudingekayo.
Ivalvu igobela kumaphi ama-ICE?
Emishinini ene-ICE enama-valve angu-8, igoba okungenani, kodwa amaseli angu-16 no-20, kungakhathaliseki ukuthi uphethiloli noma udizili, ukugoba kwenzeka ezimweni eziningi. Yiqiniso, ngezinye izikhathi kungaba i-valve eyodwa noma ngaphezulu, futhi uma injini evuthayo yangaphakathi isebenza ngokungenzi lutho, inkinga izodlula. Kodwa izimo ezinjalo zimbalwa, ikakhulukazi, imiphumela ayinakulungiseka. Ithebula elinohlu lwama-ICE lapho amavalvu azo zonke izimoto ezithandwayo agoba khona lapho ibhande lesikhathi liphuka.

Ungathola kanjani ukuthi i-valve igoba?
Ukuhlola injini evuthayo yangaphakathi uma amavalvu egobile ngemva kwekhefu lesikhathi
Kulolu daba, ukuhlolwa okubukwayo noma izinombolo ezinikezwe kumathebula "e-valve bend" ngeke kukusize. Ngisho noma usezandleni zakho ulwazi oluvela kumenzi mayelana nomonakalo uma kwenzeka ibhande eliphukile, akwaziwa ukuthi lithembeke kangakanani.
Uma ufuna ukuhlola ukuthi kungenzeka yini ukugoba ama-valve nge-piston lapho ibhande lesikhathi liphuka, udinga ukususa ibhande, usethe i-piston yokuqala ku-TDC, uvule i-camshaft 720 degrees.
Uma konke kuhambe kahle futhi akazange aphumule, ungaqhubeka ukuhlola - ukuya piston yesibili. Uma konke kuhamba kahle lapho, khona-ke ibhande eliphukile elingenzeka ngeke liholele emiphumeleni emibi yenjini evuthayo yangaphakathi yemoto yakho.
Ukuze ugweme le nkinga (ukugoba kwama-valve uma kwenzeka ikhefu), kufanele uhlale uqapha isimo nokungezwani kwebhande lesikhathi. Lapho umsindo omncane ongajwayelekile uvela ngesikhathi sokusebenza, kufanele uzame ngokushesha ukuthola imbangela yokuvela kwayo, uhlole isimo sama-roller kanye nepompo.
Lapho uthenga imoto esetshenzisiwe, shintsha ibhande lesikhathi ngokushesha, kungakhathaliseki ukuthi umthengisi ukutshela ini. Bese kuba umbuzo ophuthumayo njengokuthi ingabe i-valve iyagoba uma iphuka Ngeke uphazamiseke.
Izimpawu ze-valve egobile
Lapho ibhande liphuka, bese ushintsha nje ibhande lesikhathi, ngethemba lokuthi konke kwahamba ngaphandle kwemiphumela futhi uqala injini, akufanelekile. Ikakhulukazi uma injini evuthayo yangaphakathi isohlwini lwalabo lapho i-valve igoba khona. Yebo, kunezikhathi lapho ukugoba kwakungekukhulu futhi ama-valve amaningana angasahambisani kahle nesihlalo sehhashi, khona-ke ungakwazi ukuvula isiqalisi, kodwa ngokuvamile izenzo ezinjalo zizokwandisa isimo. Njengoba ngomonakalo omncane konke kuzosebenza futhi kujikeleze, noma kunjalo, injini yomlilo yangaphakathi izozamazama, futhi imiphumela izoba yimbi kakhulu.
Kungcono uma ususa "ikhanda" ukuze uhlole lokhu ngokubukeka noma ugcwalise uphalafini, noma kunjalo, kunezindlela eziningana zokuhlola ukuthi i-valve igobile ngaphandle kokuhlakaza injini yomlilo yangaphakathi.
Uphawu oluyinhloko uma ama-valve egobile - amancane noma aphelele akukho ukucindezela. Ngakho-ke, udinga ukukala ukucindezelwa kumasilinda. Kodwa, izenzo ezinjalo zibalulekile uma i-crankshaft ingaphendulwa futhi akukho okuphumule noma kuphi. Ngakho-ke into yokuqala okufanele uyenze ukufaka ibhande elisha, ngesandla, ngebhawodi ku-HF, skrola yonke indlela yokusabalalisa igesi ngokuphenduka okumbalwa (udinga ukuqaqa amakhandlela ngesikhathi esifanayo).
Ungahlola kanjani ukuthi i-valve igobile
ukuze unqume ukuthi isiqu se-valve sigobile yini, ukujika okuhlanu ngokoqobo kokujika ngesandla nokhiye kubhawodi ye-crankshaft kuzokwanela. Uma izinduku ziqinile, khona-ke ukujikeleza kuzoba mahhala, kugobile - kusinda. Futhi kufanele kube amaphuzu abambekayo angu-4 (nge-revolution eyodwa) yokumelana nokuhamba kwamapiston. Uma ukumelana okunjalo kungabonakali, bese ubuyisela amakhandlela emuva, uwakhulule ngalinye ngalinye bese uvula i-crankshaft futhi.
Ngamandla okunyakaza okwenziwa ngesandla, lapho elinye lamakhandlela lingekho, kulula ukuqonda ukuthi i-valve/ama-valve ibigotshwe kuyiphi isilinda. Kodwa-ke, le ndlela ngeke ikwazi njalo ukukusiza ukuthi uthole ukuthi i-valve igobile noma cha.
Uma i-crankshaft iphenduka ngokukhululekile, ungakwazi hlola nge-compression gauge. Alikho yini ithuluzi elinjalo? Kusho yenza i-pneumotest, ngaphezu kwalokho, ukuhlola ukuqina kwamasilinda kuyindlela elungile kakhulu, ezonikeza impendulo yokuthi amapuleti e-valve angena kanjani kuma-saddles, ngaphandle kwemiphumela eyengeziwe lapho upheqa nge-starter futhi ngaphandle kokufaka ibhande elisha.
Ungahlola kanjani ukuthi i-valve ngokwayo igobile?
Ukuze uthole i-pneumotest, awudingi ukudonsa imoto esiteshini sesevisi, wena ngokwakho ungathola ukuthi i-cylinder iqinile noma cha. Okulula kakhulu:
- thatha ucezu lwe-hose ngokusho kobubanzi bekhandlela kahle;
- khumula ikhandlela;
- setha i-cylinder piston endaweni ephezulu efile (ama-valve avaliwe) ngamunye ngamunye;
- faka i-hose ngokuqinile emthonjeni;
- uzama ngawo wonke amandla akho ukuvuthela ekamelweni elivuthayo (umoya udlula - ugobile, awudluli - "ushaneliwe").
Ukuhlolwa okufanayo kungenziwa kusetshenziswa i-compressor (ngisho nomshini owodwa). Yiqiniso, kuzodingeka uchithe isikhathi esengeziwe, njengoba kudingeka uzilungiselele. Khipha i-electrode emaphakathi ekhandlelani elidala, bese ufaka ipayipi endaweni ethiphu ye-ceramic (uyilungise kahle nge-clamp). Bese futha ukucindezela kusilinda (inqobo nje uma iphiston elikuyo liku-TDC).
Ngokuhayiza nangokucindezelwa esikalini sokucindezela, kuzocaca ukuthi izigqoko ze-valve zihlezi ezihlalweni noma cha. Ngaphezu kwalokho, kuye ngokuthi umoya uya kuphi, nquma indawo yokungena noma indawo egobile. Lapho i-exhaust igobile, umoya ungena ku-exhaust manifold (silencer). Uma ama-valve okungena egobile, bese ungena emgudwini wokungena.
