.Isenzo se-valve yokungena.
Indima ye-valve ibhekene ngqo nokufaka umoya enjinini futhi ikhiphe igesi yokukhipha ngemva kokusha. Kusukela esakhiweni senjini, ihlukaniswe i-valve yokungenisa kanye ne-exhaust valve. Indima yevalvu yokudonsa iwukudonsa umoya enjinini bese uwuxuba nophethiloli ukuze ushise; Umsebenzi we-valve yokukhipha ukukhipha igesi yokukhipha ngemva kokuvutha nokukhipha ukushisa.
Ukubunjwa: I-valve yakhiwe ngekhanda le-valve kanye nenduku. Ukushisa kwekhanda le-valve kuphezulu kakhulu (i-valve yokungena engu-570 ~ 670K, i-valve yokukhipha i-1050 ~ 1200K), kodwa futhi imelana nokucindezela kwegesi, amandla entwasahlobo ye-valve kanye nengxenye yokudlulisa amandla e-inertia, ukugcotshwa kwayo, izimo zokupholisa zimbi, ezidinga i-valve kumele ibe namandla athile, ukuqina, ukushisa nokugqoka ukumelana. I-valve yokukhipha ngokuvamile yenziwe ngensimbi ye-alloy (insimbi ye-chromium, insimbi ye-nickel-chromium), futhi i-valve yokukhipha umoya yenziwa nge-alloy ukumelana nokushisa (i-silicon chromium steel). Ngezinye izikhathi ukuze kugcinwe i-alloy ekwazi ukumelana nokushisa, ikhanda le-valve ephumayo lenziwe nge-alloy ukumelana nokushisa, futhi induku yenziwe ngensimbi ye-chromium, bese kokubili kuhlanganiswe ndawonye.
Ukuma kwekhanda le-valve kunengaphezulu eliyisicaba, ingaphezulu eliyindilinga kanye nophondo olungaphezulu. Ngokuvamile kusetshenziswa ingaphezulu eliyisicaba. Inhloko ye-valve eyisicaba inezinzuzo zesakhiwo esilula, ukukhiqiza okulula, indawo encane yokumunca ukushisa, isisindo esincane, futhi ingasetshenziselwa ama-valve angenayo kanye ne-exhaust. I-valve ephezulu eyindilinga ifanele i-valve yokukhipha, enamandla amakhulu, ukumelana nokukhipha umoya omncane kanye nomphumela omuhle wokuqeda igesi, kodwa inendawo enkulu yokushisa, inqwaba enkulu kanye ne-inertia, nokucubungula okuyinkimbinkimbi. Uhlobo lophondo lunomzila othize, onganciphisa ukuphikiswa kokungena, kodwa ikhanda layo lishiswa indawo enkulu, efanelekile kuphela ku-valve yokungena.
I-valve rod i-cylindrical, iphindaphinda njalo kumhlahlandlela we-valve, futhi indawo yayo kufanele ishise kakhulu futhi ipholishwe. Ukuma kokuphela kwenduku ye-valve kuncike kwifomu elimisiwe le-valve spring, isakhiwo esivame ukusetshenziswa yizicucu ezimbili zokukhiya ukulungisa isihlalo sasentwasahlobo, ukuphela kwenduku ye-valve kune-groove eyindandatho yokufaka ucezu lokukhiya, ezinye zihlanganiswe nephini lokukhiya, futhi isiphetho sinembobo yokufaka iphini lokukhiya.
Ingabe i-valve yokungenisa injini kufanele ihlanzwe?
Eqinisweni, zonke izingxenye zemoto zinokuhlanza okujwayelekile, ikakhulukazi inhliziyo yemoto - injini, uma ingahlanzwa, ukunqwabelana kwekhabhoni ngaphakathi kunganciphisa amandla enjini, kwandise ukusetshenziswa kukaphethiloli, futhi ezimeni ezibucayi kuzobangela ukushayeka kwenjini, ukusheshisa umsindo ongavamile, ukulimala kwepiston kanye ne-crankshaft, futhi ngisho ekugcineni kuholele ekushisweni kwenjini kudinga ukushintshwa. Khona-ke ukuhlanza injini, i-valve yokungena kufanele ihlanzwe, okulandelayo yinkulumo emfushane mayelana nokuhlanza i-valve yokungena.
Ukuhlanzwa kwe-valve yokuthatha, okokuqala, kuncike ekutheni ingakanani ikhabhoni efakwe, futhi kuyinto evamile ukuqongelela ikhabhoni.
Imoto ngokuvamile ingaphezu kwamakhilomitha angu-40,000, kuyadingeka ukucabangela ukuhlanzwa kwe-carbon deposition, lapho ukufakwa kwekhabhoni kucishe kubonakale. Khona-ke umnikazi uzobuza indlela yokuhlola ukuqoqwa kwe-carbon yenjini
Ungabheka kanjani ukuthi injini inamadiphozithi ekhabhoni
Indlela ilula. Goqa umunwe wakho ngethawula lesidlo sakusihlwa elimhlophe
Ngaphakathi komsila wepayipi le-exhaust, hlikihla indingilizi kanzima, bese ubheka umbala wephepha ukuze ubone ukuthi uhlelo lwenjini lunawo yini ama-carbon deposit.
Le ndlela inganquma ukuthi indawo evuthayo, ipiston kanye nediphozi yeringi yekhabhoni kusilinda senjini kubi kakhulu.
1, ipayipi umsila akukho carbon: iminwe ezisongwe napkins amhlophe, kanzima ukusula umsila ipayipi port ngaphakathi indilinga, iphepha kuphela ophuzi ukukhanya, okubonisa ukuthi injini ngaphakathi akukho carbon;
2, khipha ipayipi elintantayo carbon: indlela efanayo, wathola ukuthi ipayipi qeda has a carbon kancane black, kancane pat the napkin emhlophe ishiywe, isilinda injini, piston, umsebenzi indandatho kuyinto evamile ngokuphelele, kukhona inani elivamile carbon elintantayo (ebizwa nangokuthi carbon Foam, hhayi efakwe).
I-3, ipayipi lokukhipha ikhabhoni eliwugqinsi: usebenzisa indlela efanayo, ithole ukuthi ipayipi lokukhipha ipayipi liningi lekhabhoni elimnyama liminyene kakhulu, ngemuva kokushaya i-napkin emhlophe, kusekhona i-carbon black eningi ephepheni, okubonisa ukuthi kuyadingeka ukuhlanza igumbi lomlilo, i-piston, idiphozi ye-carbon;
4, i-exhaust pipe oil carbon: Ngokusebenzisa indlela efanayo, kutholwe ukuthi kunekhabhoni emnyama ephepheni le-napkin emhlophe, futhi kukhona amabala kawoyela, okubonisa ukuthi injini ishisa uwoyela futhi idinga ukulungiswa.
5, khipha uwoyela wepayipi intuthu ye-carbon: kunganqunywa ukuthi ngenxa yokuqoqwa kwekhabhoni nezinye izizathu, ukugqokwa kwesilinda somzimba wenjini kubi kakhulu, isidingo sokukhanda ochwepheshe. Ukuhlanzwa njalo kwezingxenye ezihlukahlukene zemoto kuhle emotweni ngokwayo, kodwa futhi nokuphepha nempilo yabo. Kungakhathaliseki ukuthi imoto yinhle kangakanani, kuyadingeka ukuyigcina isesimweni esihle.
