...Isenzo sevalve yokungena.
Indima yevalve inoxanduva ngokukodwa lokungenisa umoya kwi-injini kwaye ikhuphe igesi yokukhupha emva kokutsha. Ukusuka kwisakhiwo se-injini, yahlulwe yaba yivalve yokungena kunye nevalve yokukhupha. Indima yesivalo sokungena kukutsala umoya kwi-injini kwaye uyixube namafutha ukuze itshise; Umsebenzi we-valve yokukhupha i-valve yokukhupha igesi yokukhupha igesi emva kokutsha kunye nokutshabalalisa ubushushu.
Ukwakheka: Ivalve yenziwe yintloko yevalve kunye nentonga. Ubushushu bentloko yevalve buphezulu kakhulu (ivalve yokungena 570 ~ 670K, ivalve yokukhupha 1050 ~ 1200K), kodwa imelane noxinzelelo lwegesi, amandla entwasahlobo yevalve kunye necandelo lokuhambisa amandla e-inertia, ukuthambisa kwayo, iimeko zokupholisa zimbi, zifuna. ivalve kufuneka ibe namandla athile, ukuqina, ubushushu kunye nokumelana nokunxiba. Ivalve yokungena ngokuqhelekileyo yenziwe ngentsimbi yealloyi (intsimbi yechromium, intsimbi yenickel-chromium), kwaye ivalve yokukhupha yenziwe ngealloy enganyangekiyo kubushushu (i-silicon chromium steel). Ngamanye amaxesha ukuze kugcinwe i-alloy ekwazi ukumelana nobushushu, intloko yevalve yokukhupha yenziwe nge-alloy ekwazi ukumelana nobushushu, kwaye intonga yenziwe ngentsimbi yechromium, kwaye ke ezi zimbini zidityaniswe kunye.
Imilo yentloko yevalve inomphezulu osicaba, umphezulu ongqukuva kunye nomphezulu wophondo. Ngokuqhelekileyo kusetyenziswa umphezulu osicaba. Intloko ye-valve ye-flat-top ineenzuzo zesakhiwo esilula, ukuveliswa okufanelekileyo, indawo encinci yokufunxa ubushushu, ubunzima obuncinci, kwaye ingasetyenziselwa i-valve yokungena kunye nokukhupha. I-valve ephezulu ye-spherical ifanelekile kwi-valve yokukhupha, enamandla amakhulu, ukuxhathisa okuncinci kokukhupha kunye nefuthe elihle lokuphelisa igesi, kodwa inendawo enkulu yokufudumala, ubunzima obukhulu kunye ne-inertia, kunye nokucubungula okuyinkimbinkimbi. Uhlobo lwephondo lunomzila othile, olunokunciphisa ukuchasana kokungena, kodwa intloko yalo ishushu kwindawo enkulu, efanelekileyo kuphela kwi-valve yokungena.
Intonga yevalve i-cylindrical, ihlala iphindaphinda kwisikhokelo sevalve, kwaye umphezulu wayo kufuneka ushushu kakhulu kwaye uphuculwe. Imilo yokuphela kwentonga yevalve ixhomekeke kwifom emiselweyo ye-valve spring, isakhiwo esisetyenziswa ngokuqhelekileyo siqhekeza ezibini ze-lock yokulungisa isihlalo se-spring, isiphelo sentonga yevalve ine-groove yokufaka i-lock piece, ezinye zilungiswe ngephini lokukhiya, kwaye isiphelo sinomngxuma wokufaka i-lock pin
Ngaba ivalve yokuthatha i-injini kufuneka icocwe?
Ngapha koko, zonke iinxalenye zemoto zinokucocwa rhoqo, ngakumbi intliziyo yemoto-injini, ukuba ayicocwanga, ukuqokelelwa kwekhabhoni ngaphakathi kunokunciphisa amandla enjini, ukwandisa ukusetyenziswa kwepetroli, kwaye kwiimeko ezimandundu kuya kubangela injini. ukunkqonkqoza, ukukhawulezisa isandi esingaqhelekanga, ukonakaliswa kwepiston kunye ne-crankshaft, kwaye ekugqibeleni kukhokelela ekutshisweni kwe-oyile kufuneka ilungiswe ngokutsha. Emva koko i-injini yokucoca, ivalve yokungena kufuneka icocwe, oku kulandelayo yintetho emfutshane malunga nokucoca ivalve yokungena.
Ukucocwa kwevalve yokungena, okokuqala, kuxhomekeke ekubeni ingakanani i-carbon efakwe, kwaye kuyinto eqhelekileyo ukuqokelela ikhabhoni.
Imoto ngokuqhelekileyo ingaphezu kweekhilomitha ezingama-40,000, kuyimfuneko ukuqwalasela ukucocwa kwe-carbon deposition, xa i-carbon deposition iphantse ibonakale. Emva koko umnini uya kubuza indlela yokukhangela i-carbon accumulation ye-injini
Indlela yokukhangela ukuba injini ine-carbon deposits
Indlela ilula. Gquba umnwe wakho ngetawuli emhlophe yesidlo sangokuhlwa
Ngaphakathi komsila-isiphelo sombhobho wokukhupha, hlikihla isangqa ngamandla, kwaye ujonge umbala wephepha ukuze ubone ukuba inkqubo ye-injini ine-carbon deposits.
Le ndlela inokugqiba ukuba igumbi lokutsha, i-piston kunye ne-carbon deposit kwi-cylinder ye-injini iyingozi kakhulu.
1, umbhobho umsila akukho carbon: iminwe esongelwe napkins ezimhlophe, nzima ukusula izibuko umbhobho umsila ngaphakathi isangqa, iphepha kuphela ukukhanya yellow, ebonisa ukuba injini ngaphakathi akukho carbon;
2, umbhobho wokukhupha umbhobho odadayo wekhabhoni: indlela efanayo, yafumanisa ukuba umbhobho wokukhupha unekhabhoni emnyama encinci, ubambe ngobunono i-napkin emhlophe ishiywe, i-cylinder ye-injini, ipiston, umsebenzi weringi uqhelekile, kukho inani eliqhelekileyo lekhabhoni edadayo. (ekwabizwa ngokuba yi-carbon foam, ayifakwanga).
I-3, umbhobho wokukhupha i-carbon eshinyeneyo: usebenzisa indlela efanayo, wafumanisa ukuba umbhobho wokukhupha ubuninzi bekhabhoni emnyama unzima kakhulu, emva kokubetha i-napkin emhlophe, kusekho i-carbon emnyama eninzi ephepheni, ebonisa ukuba kuyimfuneko. ukucoca igumbi lokutsha, ipiston, idiphozithi yekhabhoni yeringi;
I-4, ibhobho ye-oyile yombhobho yokukhupha: Ukusebenzisa indlela efanayo, ifumene ukuba kukho ikhabhoni emnyama kwiphepha elimhlophe le-napkin, kwaye kukho i-oil stains, ebonisa ukuba injini iyatshisa ioli kwaye idinga ukulungiswa.
I-5, ukukhupha umsi we-oyile ye-oyile ye-carbon: kunokumiselwa ukuba ngenxa yokuqokelela kwekhabhoni kunye nezinye izizathu, ukunxiba kwe-injini ye-cylinder yomzimba kunzulu, imfuno yokulungiswa kwengcali. Ukucocwa rhoqo kweendawo ezahlukeneyo zemoto kulungile kwimoto ngokwayo, kodwa kunye nokhuseleko kunye nempilo yabo. Kungakhathaliseki ukuba ilungile kangakanani imoto, kuyimfuneko ukugcina imoto.
