Isenzo sevalvu yokungenisa.
Indima yevalvu inoxanduva ngokukodwa lokungena komoya kwinjini kunye nokukhupha igesi yokukhupha umoya emva kokutsha. Ukusuka kwisakhiwo senjini, yahlulwe yaba yivalvu yokungenisa umoya kunye nevalvu yokukhupha umoya. Indima yevalvu yokungenisa umoya kukutsala umoya kwinjini uze uwuxube nepetroli ukuze utshiswe; Umsebenzi wevalvu yokukhupha umoya kukukhupha igesi yokukhupha umoya emva kokutsha uze ukhuphe ubushushu.
Ulwakhiwo: Ivalvu yenziwe ngentloko yevalvu kunye nentonga. Ubushushu bentloko yevalvu buphezulu kakhulu (ivalvu yokungenisa 570 ~ 670K, ivalvu yokukhupha 1050 ~ 1200K), kodwa ikwamelana noxinzelelo lwegesi, amandla entwasahlobo yevalvu kunye namandla e-inertia yecandelo lokudlulisa, ukuthambisa kwayo, iimeko zokupholisa azilunganga, nto leyo edinga ukuba ivalvu ibe namandla athile, ukuqina, ubushushu kunye nokumelana nokuguguleka. Ivalvu yokungenisa ngokubanzi yenziwe ngentsimbi ye-alloy (intsimbi ye-chromium, intsimbi ye-nickel-chromium), kwaye ivalvu yokukhupha yenziwe ngentsimbi ye-alloy engatshisi ubushushu (intsimbi ye-silicon chromium). Ngamanye amaxesha ukuze kongiwe i-alloy engatshisi ubushushu, intloko yevalvu yokukhupha yenziwe nge-alloy engatshisi ubushushu, kwaye intonga yenziwe ngentsimbi ye-chromium, kwaye emva koko zombini zidityaniswa.
Imilo yentloko yevalvu ine-top ethe tyaba, i-top eyi-spherical kunye ne-horn top. Ngokwesiqhelo kusetyenziswa i-top ethe tyaba. I-head yevalvu ethe tyaba ineengenelo zesakhiwo esilula, ukwenziwa okulula, indawo encinci yokufunxa ubushushu, ubunzima obuncinci, kwaye ingasetyenziselwa ii-inlet kunye nee-exhaust valves. I-valve ephezulu eyi-spherical ifanelekile kwi-exhaust valve, enamandla aphezulu, ukumelana okuncinci kokukhupha umoya kunye nefuthe elihle lokususa igesi yokukhupha umoya, kodwa inendawo enkulu yokufudumeza, ubunzima obukhulu kunye ne-inertia, kunye nokucubungula okuntsonkothileyo. Uhlobo lwe-horn lune-streamline ethile, enokunciphisa ukumelana kokungenisa umoya, kodwa intloko yalo ifudunyezwa yindawo enkulu, efanelekileyo kuphela kwi-inlet valve.
Intonga yevalvu iyisilinda, ihlala iphindaphindana kwisikhokelo sevalvu, kwaye umphezulu wayo kufuneka ushushu kakhulu kwaye upholishwe. Ukuma kwesiphelo sentonga yevalvu kuxhomekeke kwimo emiselweyo yentwasahlobo yevalvu, isakhiwo esisetyenziswa rhoqo ziziqwenga ezimbini zokutshixa ukulungisa isihlalo sentwasahlobo, isiphelo sentonga yevalvu sinomngxuma wendandatho wokufaka into yokutshixa, ezinye ziqiniswe ngephini yokutshixa, kwaye isiphelo sinomngxuma wokufaka iphini yokutshixa.
Ngaba ivalvu yokungenisa injini kufuneka icocwe?
Enyanisweni, zonke iindawo zemoto zicocwa rhoqo, ingakumbi intliziyo yemoto - ukuba injini ayicocwanga, ukuqokelelwa kwekhabhoni ngaphakathi kunokunciphisa amandla enjini, kwandise ukusetyenziswa kwepetroli, kwaye kwiimeko ezinzima kuya kubangela ukubetheka kwenjini, ukukhawulezisa isandi esingaqhelekanga, umonakalo kwipiston nakwi-crankshaft, kwaye ekugqibeleni kukhokelela ekubeni ioyile etshayo yenjini kufuneka ilungiswe. Emva koko ukucocwa kwenjini, ivalvu yokungenisa kufuneka icocwe, oku kulandelayo yintetho emfutshane malunga nokucocwa kwevalvu yokungenisa
Ukucocwa kwevalvu yokungenisa, okokuqala, kuxhomekeke ekubeni ingakanani ikhabhoni ebekwe kuyo, kwaye kuyinto eqhelekileyo ukuqokelela ikhabhoni.
Imoto ngokubanzi ingaphezulu kweekhilomitha ezingama-40,000, kuyimfuneko ukuqwalasela ukucoca i-carbon dioxide, xa i-carbon dioxide iphantse ibonakale. Emva koko umnini uya kubuza ukuba angajonga njani i-carbon dioxide eqokelelene kwinjini.
Indlela yokujonga ukuba injini ineediphozithi zekhabhoni
Indlela ilula. Songa umnwe wakho ngetawuli emhlophe yesidlo sangokuhlwa
Ngaphakathi kwesiphelo sombhobho wokukhupha umoya, hlikihla isangqa ngamandla, uze ujonge umbala wephepha ukuze ubone ukuba inkqubo yenjini inazo na iidiphozithi zekhabhoni.
Le ndlela inokumisela ukuba igumbi lokutsha, i-piston kunye ne-ring carbon deposit kwi-injini isilinda imbi kakhulu na.
1, umbhobho womsila ongenakhabhoni: iminwe isongelwe ngeenapkin ezimhlophe, kunzima ukuyisula umbhobho womsila ongaphakathi kwesangqa, iphepha limthubi okhanyayo kuphela, nto leyo ebonisa ukuba injini ngaphakathi ayinakhabhoni;
2, umbhobho wokukhupha i-carbon eqaqanjelwayo: indlela efanayo, kwafunyaniswa ukuba umbhobho wokukhupha i-carbon emnyama kancinci, chukumisa ngobunono i-napkin emhlophe ishiywe, isilinda senjini, i-piston, umsebenzi wendandatho uqhelekile ngokupheleleyo, kukho umlinganiselo oqhelekileyo we-carbon eqaqanjelwayo (ekwabizwa ngokuba yi-carbon foam, engafakwanga).
3, umbhobho wokukhupha i-carbon etyebileyo: kusetyenziswa indlela efanayo, kwafunyaniswa ukuba umbhobho wokukhupha i-carbon emnyama eninzi kakhulu, emva kokubetha i-napkin emhlophe, kusekho i-carbon emnyama eninzi ephepheni, nto leyo ebonisa ukuba kuyimfuneko ukucoca igumbi lokutsha, i-piston, idiphozithi ye-carbon yendandatho;
4, i-carbon yeoyile yombhobho wokukhupha: Ukusebenzisa indlela efanayo, kwafunyaniswa ukuba kukho ikhabhoni emnyama kwiphepha le-napkin emhlophe, kwaye kukho amabala eoyile, nto leyo ebonisa ukuba injini itshisa ioyile kwaye kufuneka ilungiswe.
5, ioyile yombhobho wokukhupha umoya Umsi wekhabhoni: kunokugqitywa ukuba ngenxa yokuqokelelwa kwekhabhoni nezinye izizathu, ukuguguleka komzimba wesilinda yenjini kukhulu, imfuneko yokulungiswa kobungcali. Ukucocwa rhoqo kweendawo ezahlukeneyo zemoto kulungile kwimoto ngokwayo, kodwa kukwanceda ukhuseleko nempilo yazo. Nokuba imoto ilungile kangakanani na, kuyimfuneko ukuyigcina imoto ikwimeko entle.
