Zithini iivalvu zokungenisa imoto?
Ivalvu yokungenisa umoya yinxalenye ebalulekileyo kwindlela yokusebenza kwevalvu yenjini, enoxanduva lokutsala umoya omtsha (okanye umxube ovuthayo) kwisilinda ngexesha lomjikelo wokusebenza ngeenjongo zokutsha.
Umsebenzi ongundoqo
Ukuphefumla umoya: Ngexesha lokubetha kwe-intake, ivalvu yokungenisa umoya iyavuleka, isebenzisa uxinzelelo olubi oluveliswa kukuhamba kwepiston ezantsi ukuze itsale umoya (okanye umxube womoya kunye nepetroli) ungene kwisilinda.
Ukulungiselela ukutsha: Ibonelela ngeoksijini efunekayo kwiinkqubo ezilandelayo zokucinezela nokutsha, iqinisekisa ukuba ipetroli itsha kakuhle.
Ukutywina isilinda: Ngexesha lokucinezelwa, umbane, kunye nokubetha kwe-exhaust, ivalvu yokungenisa i-intake iyavalwa, kunye nevalvu yokukhupha i-exhaust, ukuqinisekisa ukutywinwa kwesilinda.
Ulwakhiwo kunye neempawu
Ulwakhiwo: Iqulathe intloko yevalvu kunye nesiqu sevalvu. Intloko idla ngokuba tyaba, ibe ngqukuva, okanye ibe tyholo, kwaye i-flat-top yeyona ixhaphakileyo.
Izinto: Yenziwe kakhulu ngezinto ze-alloy ezifana nentsimbi ye-chrome kunye nentsimbi ye-nickel-chrome ukuze imelane namaqondo obushushu aphezulu kunye noxinzelelo loomatshini.
Ubungakanani: Ihlala inkulu kunevalvu yokukhupha umoya ukuze kuncitshiswe ukumelana nokungena kwamanzi kunye nokuphucula ukusebenza kakuhle kokutshaja.
I-engile ekhonkrithi: Idla ngokuba yi-45°, kwaye ezinye iimodeli (ezifana ne-CA1091) zisebenzisa i-30° ukunciphisa ngakumbi ukumelana nokungena.
Iqhutywa yi-camshaft, ilawulwa ngokuvula nokuvala nge-tappet, i-pushrod (okanye ngqo ngengalo ye-rocker).
Ixesha lokuvula nelokuvala lilawulwa ngokuchanekileyo lixesha levalvu, elihambelana ne-engile ye-crankshaft, ukuqinisekisa ukutshintshiselana komoya okusebenzayo.
Iingcamango Eziqhelekileyo Ezingachanekanga Ingcaciso
Ayisiyo i-throttle: I-throttle ikwi-intake pipe kwaye ilawula umthamo opheleleyo wokungenisa; i-intake valve ikwintloko yesilinda kwaye ilawula ixesha lokungenisa kwesilinda enye.
Ayisosiqhoboshi: Isiqhoboshi sisiqhoboshi esiqhutywa ngumqhubi, esilawulwa ngeendlela ze-elektroniki okanye zoomatshini ukuvula i-throttle.
Impembelelo yeMpazamo
Ukuba ivalvu yokungenisa yonakele (njengokuguquguquka, ukwakheka kwekhabhoni, okanye ukutywinwa kakubi), kunokubangela:
Amandla enjini anciphileyo
Ukungahlali kakuhle, ukukhawulezisa okubuthathaka Ubunzima bokuqalisa
Umsi ophumayo ukhupha umsi omnyama okanye kukho ingxolo engaqhelekanga ngenxa yokuvuza
Uninzi lweenjini zanamhlanje zisebenzisa uyilo lweevalvu ezininzi (ezifana neevalvu ezi-4 kwisilinda nganye, ezaziwa ngokuba yi-"16V"), ukuphucula ukusebenza kakuhle kokungenisa kunye nokukhupha umoya kunye nokuphucula ukusebenza komlilo.
Ivalvu yokungenisa igesi yinxalenye ebalulekileyo kwinkqubo yesitimela sevalvu yenjini. Imisebenzi yayo ephambili yile ilandelayo:
-吸入 umoya omtsha (okanye umxube ovuthayo) kwisilinda： Ngexesha lokubetha komoya, ivalvu yokungenisa iyavuleka, ivumela umoya (kwiinjini zepetroli, udla ngokuxutywa nepetroli ukwenza umxube ovuthayo) ukuba ungene kwigumbi lokutsha, ubonelela ngeemeko ezifunekayo zokutsha.
- Ukuqinisekisa ukusebenza kakuhle kokutsha: Ngokulawula ngokuchanekileyo umthamo wokungenisa, ukuqinisekisa ukuba ipetroli iyatsha ngokupheleleyo, ngaloo ndlela kuphucula amandla enjini kunye nokonga ipetroli.
- Ukusebenza ngokubambisana nevalvu yokukhupha umoya: Kunye nevalvu yokukhupha umoya, igqibezela umjikelo we-four-stroke "wokungenisa - ukucinezela - amandla - ukukhupha umoya", ukugcina ukusebenza okuqhelekileyo kwenjini.
Ukuba ivalvu yokungenisa ayisebenzi kakuhle (njengokwakheka kwekhabhoni, ukutywinwa okungasebenzi kakuhle, okanye ukunamathela), inokubangela ezi ngxaki zilandelayo:
- Amandla enjini anciphileyo, ukungcangcazela, ukungahlaliseki
- Ukukhawulezisa okungekho semgangathweni, kunzima ukuqala
- Ukukhupha umsi omnyama, ukusetyenziswa kwepetroli okwandisiweyo
Iinjini zanamhlanje ngokubanzi zisebenzisa itekhnoloji yeevalvu ezininzi (ezifana neevalvu ezi-4 kwisilinda nganye: intake ezi-2 kunye ne-exhaust ezi-2), ukuphucula ngakumbi ukusebenza kakuhle kwe-input kunye ne-exhaust kunye nokuphucula ukusebenza kokutsha.
Ukungasebenzi kakuhle kwevalvu yokungenisa imoto kunokuchaphazela kakhulu ukusebenza kwenjini okuqhelekileyo, okukhokelela kwiingxaki ezahlukeneyo zokusebenza. Ngokweenkcukacha zoluntu ezisemthethweni, iimpawu zayo eziphambili, izizathu, kunye nezisombululo zezi zilandelayo:
- Iimpawu eziphambili
- Ukushukuma kwenjini okanye ukungahlali kakuhle: Ukungatywinwa kakuhle kwevalvu yokungenisa okanye ukwakheka kwekhabhoni kubangela umxube ongalinganiyo kwisilinda nganye, okubangela umbane ongalinganiyo, ingakumbi ngexesha lokuqala okubandayo okanye ukungahlali kakuhle.
- Ukuqala okunzima: Ukuvalwa okukhululekileyo kwevalvu kubangela ukwehla komlinganiselo woxinzelelo kwisilinda, kwaye iplagi yespark ayinakuyitshisa ngokupheleleyo le ngxubevange emva kokuyitshisa, ifuna imizamo emininzi yokuqalisa .
- Amandla anciphileyo: Umthamo wokungenisa onganeleyo okanye ukungenisa okungekho semgangathweni, okubangela ukuncipha kokusebenza kakuhle kokutsha kwamafutha, ukukhawulezisa okucothayo, kunye nokusebenza okungekho semgangathweni ukuze kudlule i-.
- Ukungaqheleki kokukhupha umoya:
Umbhobho wokukhupha umoya ukhupha umsi omnyama (ukutsha okungaphelelanga) ；
Kwiimeko ezinzima, inokukhupha umsi oluhlaza okwesibhakabhaka (ioyile etshayo, ukuba isitywino seoli yevalvu nayo yonakele).
- Ingxolo engaqhelekanga:
Isandi "esitshisayo" sinokuvakala kufutshane necala lokungenisa okanye i-intake manifold xa i-intake valve ivuza；
Ngexesha lokusebenza kwenjini, isandi "esibethayo" sinokuvakala, sibonisa ukungqongqoza kwevalvu.
- Ezinye iimpawu:
Ukuvuza komoya okugqithisileyo kwisihluzi somoya ；
I-Exhaust manifold ishushu kakhulu kwaye ide ibonise into "evuselelayo".
Izizathu eziqhelekileyo zokuphosakala
- Ukwanda kwekhabhoni: Ukusetyenziswa kwexesha elide kwepetroli engaphantsi kwamandla, ukuqhuba umgama omfutshane, ukungasebenzi kakuhle kwesitywini seoyile yevalvu, njl.njl., kukhokelela ekubekweni kwezinto ezifana neentsini, okuchaphazela ukuvulwa okanye ukutywinwa kwevalvu.
- Ukuguguleka okanye ukuwohloka komphezulu wokutywina iivalvu: Imingxuma okanye iindawo ezidityanisiweyo kumphezulu woqhagamshelwano phakathi kwevalvu kunye neringi yesihlalo phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, okubangela ukuvuza.
- Umsantsa omkhulu phakathi kwesiqu sevalvu kunye nombhobho wesikhokelo: Ivalvu iyashukuma okanye iyagoba, ayikwazi ukufakwa nokuvalwa ngokufanelekileyo .
- Ukungasebenzi kakuhle kwentwasahlobo yevalvu: Ukungaqini kakuhle okanye ukwaphuka kwentwasahlobo, okuthintela ivalvu ukuba ingavaleki kakuhle.
- Ukulungiswa okungafanelekanga kokuvuleka kwevalvu: Isiqu sevalvu siyatyhalwa sivuleke ngenxa yokwanda kobushushu, nto leyo ebangela ukuvalwa okubi.
- Amanyathelo onyango acetyiswayo
- Ukuzihlola kokuqala:
Jonga ukuba ukhe wasebenzisa amafutha aphantsi kutshanje na;
Qaphela ukuba kukho iimpawu eziqhelekileyo ezifana nomsi omnyama, ingxolo engaqhelekanga, okanye ukungcangcazela.
Sebenzisa isixhobo sokuxilonga se-OBD:
Funda iikhowudi zempazamo, ezifana neekhowudi zokucima umbane (uthotho lwe-P0300), isivamvo seoksijini esingaqhelekanga (P0130), njl. njl., ukunceda ekugwebeni .
- Ukulungiswa kobungcali
Ukuba kucingelwa ukuba ivalvu yokungenisa yingxaki, isigqubuthelo sevalvu kufuneka sihlulwe ukuze kujongwe ukuba ivalvu ivuliwe na, ukusebenza kokutywina, kunye nokwakheka kwekhabhoni;
Ukuba i-carbon building imbi kakhulu, cinga "ngokucoca inkqubo yokungenisa iikhemikhali" okanye "ukuyiqhaqha ukuze kucocwe ngesandla" ；
Ukuba ivalvu itshile, ikhubazekile, okanye ayinayo itywino ilungileyo, kudla ngokuba yimfuneko "ukutshintsha ivalvu" okanye "ukulungisa iringi yesihlalo sevalvu".
- Amanyathelo okuthintela
Sebenzisa rhoqo izongezo zepetroli kunye nepetroli ezikumgangatho ophezulu;
Coca iidipozithi zekhabhoni rhoqo emva kweekhilomitha ezingama-20,000 (ingakumbi umzimba we-throttle kunye ne-intake manifold). Buyisela izitywini ze-oyile zevalvu kunye nezihluzi ezintathu ngokwemiyalelo yesandla.
Qaphela: Ukuba ingxaki ngevalvu yokungenisa ayikhathalelwanga, inokukhokelela kumonakalo omkhulu woomatshini ofana nokubanjwa kwevalvu okanye ukungqubana kwepiston nevalvu, kwaye iindleko zokulungisa ziya kunyuka kakhulu.
