Iimpawu semigudu elinyukayo. ucinezelo Low akwitankana lokugcina. valve replacement

iinjini Modern zixhotyiswe nge kwinkqubo semigudu. Ngaphezu koko, akukho uyilo lula, kuba ichanile kakhulu, kodwa oko akuthethi ukukhusela vana umonakalo. Ngelishwa, ivelufa atshiswe-out - yingxaki eliqhelekileyo ukuba zombini ipetroli nedizili powertrains. Iimpawu semigudu otshiswayo ibonakala kuphela xa injini endala, kodwa omnandi kakhulu. Dlala lo injini kunye ivelufa atshiswe-out akunakwenzeka, ngoko ke abaqhubi beemoto abo basandula kuqalisa kuya kuba luncedo ukwazi, apho wenza ingxaki enjalo, ukuba benze ntoni kwimeko enjalo, ziziphi iimpawu i lembandezelo.

Kutheni aqhumisele ngalo vana?

Eneneni, izizathu ezininzi. Kuba ezo injini apho umenzi ekucetyiswa ukwenza ngamaxesha hlengahlengiso wevalufa, le ngxaki kwenzeka ngenxa sentlalo senziwe ngexesha ephosakeleyo yokuba backlashes thermal. On Motors apho inkqubo hlengiso umsantsa lwenziwa ngokuzenzekelayo, lungangaphumeleli lifters - ngenxa vana isha nje.

Kukho ezinye zezizathu ezininzi ezithandwayo, isiphumo apho omnye - elinyukayo ngalo mbhojana. Ngoko ke, isizathu yokuqala - iinkcukacha ukurhintyelwa kakhulu kunene. Okulandelayo - emkhonweni vana sikhokelo sikwimo imandundu kakhulu. Kungenzeka kwakhona rhoqo ukuze agcine bar banxibe. Kwaye esinye isizathu - umsebenzi kwi injini na ezinqinileyo, ngokufuthi ujongene nengxaki abanini nokudinwa kwezithuthi nesebenza negesi. Amaninzi bazitshisa izinto zeemoto. Bavuka umnyele kumaqondo obushushu aphezulu kakhulu ugwebu. Ivelufa eceleni ngexesha umsebenzi lupholisiwe yi ngomxube amafutha kunye nomoya.

Operating iziqalelo lobushushu zeemoto - malunga 400 degrees. Le valve, ngokuchaseneyo ugwebu, akukho lupholile, ukongeza ngakumbi shushu ngenxa iigesi zeemoto. Emva koko, le valve ukuba lashushu izidanga malunga 650.

Ipesenti enkulu amalungu umtshato - yingxaki abaqhubi beemoto

Lo asinguye na sizathu siphambili ngenxa apho aqhumisele ngalo mbhojana. A umenzi phambili la malungu benza uphando, kunye nezibalo ukuba akonwabanga - umba ngamnye wesihlanu, apho iveliswa, ikhefu okanye ukutsha ngenxa umba yabantu nomtshato. Nkqu nolawulo lomgangatho mihla kwi mveliso akuqinisekisi ukuba umba akanalo naziphi na iziphene. Esinye isizathu - inhomogeneities metallurgical, ezifakwe kwi ingxubevange. Ezi inhomogeneities yenza ivelufa ithambile kumele kube. Ukongeza, kukho mveliso iziphene, eyile nasekuqiniseni. Oku kukhokelela microcracks. Iimpazamo ngexesha unyango ubushushu kukhokelela ekubeni imilinganiselo imveliso ziyahluka.

Imiphumo yayifika

Ukuba ivelufa ngaba yimali, oko kwangoko batshatyalaliswe. Iziqwenga vele bawela egumbini layo komlilo. Ngenxa yoko, i-injini yayonakele kakhulu - kufuneka ukulungiswa kakhulu. Pistons Ngoko ke, i kakhulu umonakalo, intloko cylinder kunye nesilinda block. Kodwa kukho ingozi enkulu ukuba ziingceba ezinkulu otshiswayo watshayela stroke vana kwe block cylinder, yaye oku okunene ukusilela nje amacandelwana piston kunye nentloko cylinder elo qela, kodwa ke block njengesilinda.

Akukho mfuneko yokuba ukusebenza injini apho iimpawu ivalve elinyukayo waphawula. It igcwele neendleko eziphezulu ukulungiseka, yaye kwimeko okubi - ukubuyisela motor yonke. Kubhetele ukuba uqaphele le ngxaki ngendlela ngexesha, yaye ke ngenxa yoko - kuphela replacement vana. Imiphumo isithuthi yokusebenza ndinamadini vana inokuba nomahluko - ukusuka amafutha landa kakhulu anyukayo ngokupheleleyo phambi kwesihlalo vana.

iimpawu le ngxaki

Ngenxa yoko, iimpawu eziphambili kwezivalo elinyukayo - nalo injini. Isiphumo sale nto oqaphelekayo kakhulu, kwaye kunokubonwa kuzo zonke iindlela ukusebenza unit yamandla. Ukongeza, i-injini ulahlekelwa enkulu bamandla ayo. Esinye isizathu - ukusetyenziswa aphezulu amafutha. Lokufunyaniswa le ukusilela kukho yokuntsonkotha ethile. Inyaniso yeyokuba, ukuba ivelufa kwelo lizwe, iimpawu ezifana kakhulu ezinye iimpazamo. Kulo mzekelo, umnini wesithuthi iya kuba qiniseka nezokugqibela, yinto enye, nokuwa okungephi. Le iindleko ezongezelelekileyo kunye nesenzo.

valve umsebenzi we-injini

Ivalve kwi injini ludlala indima ebalulekileyo. Le nto ivumela amafutha-air umxube flow kungena isayizi. Ukongeza, ivalve onoxanduva ukukhutshwa kwegesi zeemoto emva kokuphela komjikelo. Isiqalelo osoloko esebenza nokuba iimeko ezinzima gqitha, ezikhohlakeleyo. ngokuqhubekayo kokuba sijongana amaqondo aphezulu kunye neegesi. Ekuhambeni kwexesha, inxalenye wentsimbi ibhuqiwe watshisa.

amaninzi kakhulu iimpawu kwezivalo otshiswayo kungabonwa kwiimoto abadala, izahlulo injini ezenziwe ngezinto umgangatho ayikho. Abantu abaninzi ukudala ngokwazo lembandezelo. Ngokufuthi, le motor iMisebenzi ezisezantsi umgangatho kwaye maxa wambi nkqu zilungiselelwe icandelo amafutha ethile. Ngenxa yoko, amaqondo obushushu yokutsha ngaphezulu kungakhokelela kumonakalo nentshabalalo intloko njengesilinda.

ubuxhakaxhaka diagnostic

Abanye abantu bakholelwa ukuba ivelufa kwelo lizwe, iimpawu kunye iingxaki ziya ihleli kwinkqubo ucinezelo. Amaxesha amaninzi, ukukhanda imoto, amava apho Kusekho encinane, okokuqala bonke baqala ukubona yaye alungise oko Imigudu. Xa inkqubo nokulungiswa esilolo hlobo ithathwa cover tramblera iingcingo eliphezulu-ombane indawo, amakhandlela. Kwakhona, i-engile ucinezelo umiselwe - isiphumo, kakade, ekungasayi kubuye kubekho injalo. Injini njengoko yokusebenza yaye iya kusebenza. Smith iza ufuna le ngxaki emva koko, ngaphandle ukwazi isizathu sokuba le ngxaki. Nkqu fitters, ngubani elithekelelwayo ukuba ingxaki ilele kwi injini, nibone imiqondiso semigudu elinyukayo kuphela emva kokuba ukususwa intloko njengesilinda.

Uxilongo Ukudinwa ye ivalve ngaphandle kokususa intloko cylinder

In inyathelo lokuqala ligqibe lombhobho ukuba engasebenziyo. iindlela Test efanayo kwinkqubo kwamakhandlela dummy diagnostic. Kuba intlama kubuywa naxa ukusebenza kwi idle ukususa iminqwazi yintlantsi kwiplagi.

Okulandelayo kufuneka ukuba bawajonge ngenyameko motor isebenza njani. Ukuba unit zatroil kakhulu ngaphezu phambi kovavanyo, ukuba etyetyisiweyo, ngoko eli itankana konke kulungile. Noko ke, ukuba uhlobo injini ayikatshintshi, oku kubonisa ingxaki akwitankana lokugcina. Emva koku iphume le yekhandlela lombhobho akubufumana indawo yokusebenza iyaziwa. Kwakhona, kubalulekile ukukhangela kwicingo eliphezulu-ombane ukuya kuyo. Ukongeza, khangela le lale ucinezelo. sungula Further motor iya kubonisa apho yaphela ingxaki. Ukuba imoto emva amakhandlela ukutshintshwa kunye nezinye izinto ayitshintshi na uhlobo lomsebenzi kunye troit iqhubeka, kukho kubonakala kakhulu ukuba ivelufa nangoku yimali.

fault kwasendaweni

Eyona ndlela ziqhelekileyo kwaye olusebenzayo yokumisela vana elinyukayo - imilinganiselo ucinezelo. Ukuba iziphumo zibonisa ucinezelo ephantsi, ngoko oku ngokucacileyo uphawu yayifika. Kodwa nantsi ke kuyimfuneko ukuba kwi-akhawunti ezincinane elincinane - kunye imilinganiselo ucinezelo ayikwazi ngaphandle CPG iziphene. ucinezelo ephantsi nje ngenxa kuphela adinwe. nezinye izifo ezahlukeneyo kunciphisa nto - umzekelo, kusenokuba kukuphanza Imisesane. Ngoko ke, ukuba kukho zonke iimpawu vana elinyukayo Vaz-2109 okanye nawuphi na imoto enye, kuya kufuneka ukuba ukufumanisa ngakumbi emotweni. Indlela elula ukunceda ukumisela nokudinwa emva komlinganiselo - ukugcwalisa imali encinane yeoli ibe lombhobho. ucinezelo Eminye akalwa kwakhona. Kulindeleke ukuba sikhule - kubhaliwe kwathiwa, nto leyo idala umboniso yeoli. Oku Zinjalo inkqubo piston kunxitywe. Ukuba ucinezelo akawatshintshi loo manqaku, ngoko ke ngokuqinisekileyo baphelelwe. Indlela yokuphuma - valve replacement.

Enye indlela diagnostic - uhlolo Visual ingxaki yintlantsi kunye egumbini yokutsha. Ukuba amakhandlela kwakungafani neplaque, ngoko oku kube ngumqondiso ocacileyo semigudu yayifika. Ukongeza, ukusuka elifut- uya ukuvakalisa okanye umsi.

injini ucinezelo

Ibizwa uxinzelelo ucinezelo ukuthi kubanga piston akwitankana ngexesha lokufumana iziko yokuqala phezulu ufile.
Yintoni kufuneka ucinezelo kwi injini kuxhomekeke kudidi injini. Umzekelo, ngokuba Vaz-2109 igqalwa ucinezelo eliqhelekileyo 11 kg / ^cm-3, kwaye Vaz-2110 - 13 kg / cm ^3. Kuba inkoliso level izithuthi ucinezelo sivela 11 ukuya kwi-13 kg / cm ^3. Ukuba imilinganiselo ukubonisa amanani asezantsi, oko kuthetha ukuba kuyimfuneko ukuhlola injini. Mhlawumbi sele wayitshisa ngalo mbhojana.

Ngamafuphi

Iimpawu zokuqala nokudinwa vana - yinto ithuba lokuba uxilongo Ekuqaleni injini. Ukuba isithuthi ifuna isivingco ulawulo, ngoko le misebenzi kufuneka ibe ngqongqo phantsi imithetho umenzi. Musa ukulinda, xa beqalisa kokuphuma ingxolo. Kufuneka uyazi into ucinezelo kufuneka ibe injini ngexesha ukutyhila umonakalo ukuhlaziya ngaphandle imiphumo. Kwabo bafuna ukugcina nokugcina imoto kwi igesi, kufuneka sinikele ingqalelo ubuninzi ku mindzulamiso. On ezi-injini kucetyiswa ukwenza utshintsho lwe izithuba ucinezelo zonke amawaka-10. Km. iinjini igesi basengozini, lo gama ipetroli nokudinwa kwenzeka kunqabile.
