Yintoni umgaqo womsebenzi wesitywino seoyile yevalvu yemoto?
Itywina yeoyile yevalvu yenjini yinxalenye ebalulekileyo yokutywina kwinjini. Umsebenzi wayo ophambili kukuthintela ioyile yenjini ukuba ingangeni kwi-intake manifold, kwi-exhaust pipe, nakwigumbi lokutsha, kunye nokuthintela ukuvuza kwegesi exutyiweyo kunye neegesi zokukhupha umoya, ngaloo ndlela kuqinisekiswa ukusebenza kokutywina kunye nokusebenza okuqhelekileyo kwangaphakathi kwenjini.
Umgaqo wokusebenza uxhomekeke kakhulu kuyilo olukhethekileyo lwesakhiwo kunye neempawu zezinto eziphathekayo. Iinkcukacha zezi zilandelayo:
Indlela yokutywina: Itywina yeoyile yevalvu ifakelwe kwisiqu sevalvu kwaye ixhaswa yifreyimu yangaphandle ukuqinisekisa ukuba itywina yeoyile ayiguquguquki phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu; inxalenye yeradial ifakwe intwasahlobo eziqinisayo okanye ucingo lwentsimbi, olunokuhlala lunamathele kumphezulu wesiqu sevalvu, lwenze itywina eliguqukayo. Nokuba ngexesha lokuvulwa nokuvalwa rhoqo kwevalvu, inokuthintela ngempumelelo ukuvuza kweoyile yenjini kwisiqu.
Iimpawu zezinto: Umzimba oyintloko wesitywini seoyile udla ngokwenziwa nge-fluororubber, eneempawu ezintle kakhulu zokuxhathisa amaqondo obushushu aphezulu kunye nokuxhathisa ukugqwala kweoyile, kwaye inokugcina ukuthamba kunye nokusebenza kokutywina kwindawo yenjini ngamaqondo obushushu afikelela kwiidigri Celsius ezilikhulu, ixhathisa ukukhukuliseka kweekhemikhali yeoyile yenjini.
Inkqubo yokusebenza: Xa ivalvu ivaliwe, isitywino seoli yevalvu sikwimeko yokuvaleka, okuthintela ioyile yenjini kwigumbi levalvu ukuba ingangeni kwigumbi lokutsha okanye inyuke iye kwiipayipi zokungenisa kunye nezokukhupha umoya; xa ivalvu ivuleka, isitywino seoli sihamba nevalvu, kodwa sixhomekeke kwisakhiwo esiziqinisayo ukuze sihlale sinamathele, siqinisekisa ukuba isitywino asiphazanyiswa.
Ukuba i-valve oil seal iyaguga okanye yonakele, i-injini iya kungena kwigumbi lokutsha ize itshiswe, nto leyo ebangela iingxaki ezifana nokutsha kwe-injini, umsi oluhlaza okwesibhakabhaka ovela kumbhobho wokukhupha umoya, ukwanda kwe-carbon deposits, kunye nokuncipha kwamandla. Ke ngoko, ukuhlolwa rhoqo kunye nokutshintshwa ngexesha elifanelekileyo kwe-valve oil seals eyonakeleyo kubaluleke kakhulu ekugcineni ukusebenza kunye nobomi benjini.
Ukusilela kwetywina yeoyile yevalvu yenjini kubhekisa ekwaluphaleni, ekonakalisweni, okanye ekungaphumeleli kwetywina yeoyile yevalvu, okubangela ukuba ioli yenjini ingene kwigumbi lokutsha kwaye ithathe inxaxheba kwinkqubo yokutsha, ngaloo ndlela ibangele uthotho lweziganeko ezingaqhelekanga. Nangona itywina yeoyile yevalvu incinci, umsebenzi wayo ubalulekile. Nje ukuba yonakale, iya kuchaphazela ngqo ukusebenza kwenjini kunye nobomi bayo.
Iimpawu eziphambili zokungasebenzi kakuhle kwetywina yeoyile yevalvu
Umsi oluhlaza okwesibhakabhaka ophuma kwi-exhaust: Olu lolona phawu luqhelekileyo. Xa injini iqala, ingasebenzi, okanye ikhawuleza ngequbuliso, umbhobho wokukhupha umoya uya kukhupha umsi oluhlaza okwesibhakabhaka rhoqo, oluphawu lokutsha okungaphelelanga kweoyile yenjini.
Ukusetyenziswa kweoyile okukhawulezileyo ngendlela engaqhelekanga: Ngaphandle kokuvuza okubonakalayo, inqanaba leoyile liyehla kakhulu kwixesha elifutshane (njengokukwiikhilomitha ezimbalwa), kwaye ioyile yenjini kufuneka izaliswe rhoqo.
Iidipozithi ezinkulu zekhabhoni kwiiplagi zespark: Emva kokuba ioyile yenjini ingenile kwigumbi lokutsha, iya kwenza iidipozithi zekhabhoni ezimnyama, ezinamafutha kwii-electrode zeplagi yespark, nto leyo ebangela ukutsha okungalunganga kunye nokushukumisa injini, ukungahlali kakuhle, okanye ukulahleka kwamandla.
Amandla enjini anciphileyo, ukukhawulezisa okubuthathaka: Ngenxa yokusebenza okuphantsi kokutywinwa kwesilinda, uxinzelelo olungonelanga lokucinezelwa, kunye nokusebenza okuncitshisiweyo kokutsha, isithuthi siya kubonisa ukukhawulezisa okucothayo kunye nombane onganeleyo.
Amabala eoyile okanye ukufuma kwindawo yokukhupha umbhobho wokukhupha umoya: Iintsalela ezifana neoyile okanye amabala amanzi anokubonakala kwindawo yokukhupha umbhobho wokukhupha umoya, ehamba nevumba elimnandi leoyile yenjini.
Umsi oluhlaza okwesibhakabhaka obonakalayo ngakumbi xa uqala ukubanda: Emva kokuba isitywino seoli yevalvu sigugile, ioyile yenjini iya kungena kwisikhokelo sevalvu xa imoto ipakwe ebusuku, kwaye ukuvuza kuba kukhulu xa injini ibanda. Imeko yomsi oluhlaza okwesibhakabhaka ibaluleke kakhulu.
Izizathu eziqhelekileyo zokungasebenzi kakuhle kwetywina yeoyile yevalvu
Ukwaluphala kwendalo: I-valve oil seal idla ngokwenziwa nge-fluororubber okanye i-silicone rubber. Ivezwa kubushushu obuphezulu kunye noxinzelelo oluphezulu ixesha elide, kwaye irabha iya kuqina, iqhekeke, kwaye ilahlekelwe bukuqina, nto leyo ekhokelela ekusileleni kokuvala.
Ukukhukuliseka kwekhabhoni: Ukusetyenziswa kwexesha elide kweoyile yenjini engasebenzi kakuhle okanye ukuqhuba umgama omfutshane rhoqo kunokwenza iidiphozithi zekhabhoni kwisikhokelo sevalvu, zinxibe umlebe wesitywini seoyile.
Ukuhlanganiswa okungafanelekanga: Xa kutshintshwa, ukuba akukho zixhobo zikhethekileyo zisetyenzisiweyo, indlela yokufaka ayichanekanga, okanye akukho oyile yenjini itshisiweyo, kulula ukubangela umonakalo kwisitywini seoyile.
Ukushisa kakhulu kwenjini okanye ukuthambisa okungekho semgangathweni: Ubushushu obuphezulu bukhawulezisa ukuguga kwerabha, kwaye ioyile yenjini esemgangathweni ophantsi okanye isekethe yeoyile evaliweyo inokubangela ngokungathanga ngqo ukuba isitywini seoyile singaphumeleli.
Ungajongana njani nokusilela kwetywina yeoyile yevalvu?
Itywina yeoyile yevalvu ayinakulungiswa kwaye kufuneka itshintshwe.
Icebo lokutshintsha:
Ukuba zonakele izitywini zeoyile zevalvu yesilinda esi-1-2 kuphela, isigqubuthelo sevalvu singashiywa singaphazanyiswa, kwaye umoya oxinzelelweyo ungafakwa ngomngxuma weplagi yespark ukuze ubambe ivalvu, uze usebenzise izixhobo ezikhethekileyo ukutshintsha.
Ukuba ii-cylinder ezi-3 nangaphezulu zinengxaki, okanye injini ibisoloko iqhutywa ixesha elide (njengeekhilomitha ezingaphezu kwe-100,000), kuyacetyiswa ukuba uqhaqhe isigqubuthelo sevalvu siphela, utshintshe zonke izitywini zeoyile zevalvu ngokulinganayo, kwaye uphephe ukulungiswa rhoqo kwixesha elifutshane.
Amanyathelo okuthintela ukutshintshwa:
Sebenzisa iindawo zokuqala okanye ezikumgangatho ophezulu (izinto ze-silicone ezicetyiswayo, ukumelana nobushushu okungcono).
Inkqubo yokutshintsha ifuna izixhobo zobungcali kunye nobuchwepheshe. Kucetyiswa ukuba iqhutywe yivenkile yokulungisa eqhelekileyo ukuze kuthintelwe ukungcola ukungena enjinini okanye ukufakwa okungafanelekanga okubangela umonakalo wesibini.
Emva kokutshintshwa, kuyacetyiswa ukuba ucoce ikhabhoni yenjini ukuze ubuyisele ukucoceka kwegumbi lokutsha kunye nokusebenza kwamandla.
Iingcebiso zokuthintela
Rhoqo tshintsha ioyile yenjini eyenziweyo esemgangathweni ophezulu kwaye utshintshe isihluzi seoyile ngokwemijikelo ecetyiswayo ngumvelisi.
Kuphephe ukuqhuba umgama omfutshane ixesha elide kunye nokungaqhubi rhoqo, okuvumela injini ukuba ifudumale ngokupheleleyo, nto leyo enceda ekunciphiseni iidipozithi zekhabhoni.
Nika ingqalelo ekujongeni imeko yesithuthi. Ukuba ufumana ukukhupha umsi okungaqhelekanga okanye ukusetyenziswa kweoyile ngokukhawuleza, jonga ngokukhawuleza.
Ubomi obuqhelekileyo benkonzo yesitywina seoyile yevalvu buqhele ukuba phakathi kweekhilomitha ezingama-80,000 kunye ne-150,000, kodwa buchaphazeleka kakhulu yindawo engqongileyo yesithuthi kunye nemikhwa yokugcinwa kwaso. Ukuba imoto isondela kule mileage, kuyacetyiswa ukuba uyijonge ngenkuthalo ngexesha lokugcinwa kwaso.
