Isenzo sevalvu yokungenisa.
Indima yevalvu ibhekene ngqo nokufakwa komoya enjinini kanye nokukhipha igesi yokukhipha umoya ngemva kokusha. Kusukela esakhiweni senjini, ihlukaniswe ngevalvu yokungenisa umoya kanye nevalvu yokukhipha umoya. Indima yevalvu yokungenisa umoya ukudonsa umoya enjinini bese uyixuba nophethiloli ukuze ushise; Umsebenzi wevalvu yokukhipha umoya ukukhulula igesi yokukhipha umoya ngemva kokusha futhi ukhiphe ukushisa.
Ukwakheka: Ivalvu yakhiwe ngekhanda levalvu kanye nenduku. Izinga lokushisa lekhanda levalvu liphezulu kakhulu (ivalvu yokungenisa 570~670K, ivalvu yokukhipha 1050~1200K), kodwa futhi imelana nengcindezi yegesi, amandla entwasahlobo yevalvu kanye namandla e-inertia yengxenye yokudlulisa, ukuthambisa kwayo, izimo zokupholisa azinhle, okudinga ukuthi ivalvu ibe namandla athile, ukuqina, ukushisa kanye nokumelana nokuguguleka. Ivalvu yokungenisa ngokuvamile yenziwe ngensimbi ye-alloy (insimbi ye-chromium, insimbi ye-nickel-chromium), kanti ivalvu yokukhipha yenziwe nge-alloy engamelani nokushisa (insimbi ye-silicon chromium). Ngezinye izikhathi ukuze kongiwe i-alloy engamelani nokushisa, ikhanda levalvu yokukhipha lenziwa nge-alloy engamelani nokushisa, kanti induku yenziwe ngensimbi ye-chromium, bese kuthi zombili zihlanganiswe ndawonye.
Ukuma kwekhanda le-valve kune-top eyisicaba, i-top eyindilinga kanye ne-horn top. Ngokuvamile kusetshenziswa i-top eyisicaba. Ikhanda le-valve eliyisicaba linezinzuzo zesakhiwo esilula, ukwenziwa okulula, indawo encane yokumunca ukushisa, isisindo esincane, futhi lingasetshenziswa kuma-valve okungena nawokukhipha. I-valve ephezulu eyindilinga ifanele i-valve yokukhipha, enamandla aphezulu, ukumelana okuncane kokukhipha kanye nomphumela omuhle wokususa igesi yokukhipha, kodwa inendawo enkulu yokushisa, isisindo esikhulu kanye ne-inertia, kanye nokucubungula okuyinkimbinkimbi. Uhlobo lwe-horn lunomugqa othile, onganciphisa ukumelana kokungenisa, kodwa ikhanda lalo lishiswa yindawo enkulu, efaneleka kuphela i-valve yokungenisa.
Induku yevalvu iyisilinda, ihlala iphindaphindana kumhlahlandlela wevalvu, futhi ubuso bayo kumele bushiswe kakhulu futhi bupholishwe. Ukuma kwengxenye yenduku yevalvu kuncike esimweni esiqinile sentwasahlobo yevalvu, isakhiwo esivame ukusetshenziswa yizingcezu ezimbili zokukhiya eziyingxenye yokulungisa isihlalo sentwasahlobo, ingxenye yenduku yevalvu inomsele wendandatho wokufaka ingxenye yokukhiya, ezinye ziqiniswe ngephini yokukhiya, kanti ingxenye inembobo yokufaka iphini yokukhiya.
Ingabe ivalvu yokufaka injini kufanele ihlanzwe?
Eqinisweni, zonke izingxenye zemoto zihlanzwa njalo, ikakhulukazi inhliziyo yemoto - injini, uma ingahlanzwanga, ukuqongelela kwekhabhoni ngaphakathi kunganciphisa amandla enjini, kwandise ukusetshenziswa kukaphethiloli, futhi ezimweni ezimbi kakhulu kungabangela ukushayisana kwenjini, ukusheshisa umsindo ongajwayelekile, ukulimala kwepiston kanye ne-crankshaft, futhi ekugcineni kuholele ekutheni uwoyela oshiswa yinjini udinga ukulungiswa kabusha. Ngemuva kwalokho ukuhlanzwa kwenjini, i-valve yokungenisa kumele ihlanzwe, okulandelayo yinkulumo emfushane mayelana nokuhlanzwa kwe-valve yokungenisa
Ukuhlanzwa kwevalvu yokungenisa, okokuqala, kuncike ekutheni ingakanani ikhabhoni ebekwe, futhi kuvamile ukuqongelela ikhabhoni.
Imoto ngokuvamile ingaphezu kwamakhilomitha angu-40,000, kubalulekile ukucabangela ukuhlanza ukufakwa kwekhabhoni, lapho ukufakwa kwekhabhoni kusobala. Umnikazi uzobuza ukuthi angakuhlola kanjani ukuqongelela kwekhabhoni enjinini.
Indlela yokuhlola ukuthi injini inamadiphozithi ekhabhoni
Indlela ilula. Songa umunwe wakho ngethawula elimhlophe lesidlo sakusihlwa
Ngaphakathi kokuphela komsila wepayipi lokukhipha umoya, hlikihla indilinga kanzima, bese ubheka umbala wephepha ukuze ubone ukuthi uhlelo lwenjini lunezinhlayiya zekhabhoni yini.
Le ndlela inganquma ukuthi igumbi lokushisa, i-piston kanye ne-ring carbon deposit ku-cylinder yenjini kuyingozi kakhulu.
1, ipayipi lomsila elingenakhabhoni: iminwe egoqwe ngama-napkin amhlophe, kunzima ukusula ipayipi lomsila ngaphakathi kwesiyingi, iphepha liphuzi kuphela elikhanyayo, okubonisa ukuthi injini ngaphakathi ayinakhabhoni;
2, ipayipi lokukhipha umoya elintantayo: indlela efanayo, yathola ukuthi ipayipi lokukhipha umoya linekhabhoni encane emnyama, thinta ngobumnene indwangu emhlophe esele, isilinda senjini, i-piston, umsebenzi wendandatho ujwayelekile ngokuphelele, kukhona inani elijwayelekile lekhabhoni elintantayo (elibizwa nangokuthi i-carbon foam, elingafakwanga).
3, ipayipi lokukhipha umoya elinobukhulu bekhabhoni: kusetshenziswa indlela efanayo, kwatholakala ukuthi ipayipi lokukhipha umoya liningi kakhulu, futhi ngemva kokushaya indwangu emhlophe, kusekhona i-carbon emnyama eningi ephepheni, okubonisa ukuthi kuyadingeka ukuhlanza igumbi lokushisa, i-piston, idiphozithi yekhabhoni eliyindandatho;
4, ipayipi lokukhipha umoya i-carbon kawoyela: Besebenzisa indlela efanayo, bathole ukuthi kukhona ikhabhoni emnyama ephepheni le-napkin elimhlophe, futhi kukhona amabala kawoyela, okubonisa ukuthi injini ishisa uwoyela futhi idinga ukulungiswa.
5, uwoyela wepayipi lokukhipha umoya Intuthu yekhabhoni: kungatholakala ukuthi ngenxa yokuqongelela ikhabhoni nezinye izizathu, ukuguguleka komzimba wesilinda yenjini kuyinto enkulu, isidingo sokulungiswa kochwepheshe. Ukuhlanza njalo izingxenye ezahlukene zemoto kuhle emotweni uqobo, kodwa futhi nangokwezokuphepha kwazo kanye nempilo yazo. Kungakhathaliseki ukuthi imoto inhle kangakanani, kuyadingeka ukuyinakekela.
