Izizathu kwayama le injector: siqonda ingxaki

Kukho ezizuzwa imoto baninzi, ngenxa apho umsebenzi isithuthi ngakumbi uba kuyingxaki. Ezi iziphene ibhekisela isithuthi imposiso nokusebenza okanye R0171 Inani u 0171. La manani zibonisa umxube phambi repauperization. Ezi zizathu kakhulu ezahlukeneyo sayame kwi injector. Okokuqala, kufuneka sijonge imeko kumatshini ngexesha ukusetyenziswa ezinqinileyo.

iimpawu engenamafutha

Le Imposiso siboniswe umkhusane BC. Oku kubonisa ukuba amafutha kwi umxube air-fuel incinane kakhulu emoyeni. Ukufumaneka umxube ndayame ivela njenge misfire okanye sasibambezeleka ezibukhali ngokucinezela emoto. Kwezinye iimeko, le injini nga troit okanye ngokupheleleyo ukumisa umsebenzi wabo kwi bengasebenzi. Ukongeza, ngexesha unikezelo uphakamisa isithuthi kunye injini isandi ezahlukeneyo kakhulu kwaye yahlukile isandi injini ngexesha lomsebenzi eliqhelekileyo. Ukusebenza unit samandla xa usebenzisa umxube ndayame ayikho izinzile.

Nemigangatho Isalathisi umxube kunye neziphumo kunokwenzeka

Kuba kweenqwelo oluqhelekileyo "Euro-2" okanye ngaphezulu phezu iinjini zafakelwa zincwadi Womenzi - a probe Lambda. Ilawula umgangatho mxube. Phantsi umgangatho lwabonisa ukuba inxalenye enye diesel ku-14 iindawo emoyeni. Ukuba ecaleni elinganiselwe 0.25, ikhompyutha ekwinqwelo izakunika isiphoso ezinqinileyo. On ukungena repauperization mxube yokusilela injini kwenzeka nje kuphela ukusebenza, kodwa ithuba injini nobushushu. Izinga ngesantya phansi ngokwaneleyo. Ukongeza, ukuba ngaba uchitha sifo umgangatho kunye nokuvala unobangela ukuyilwa iphilile, ngoko iziphumo ziya kuba nosizana kakhulu ngakumbi:

• nobushushu of unit amandla;
• abase-out amakhonkco piston;
• abase-out semigudu;
• eliphantsi lugxile injini;
• Pistons yayifika;
• amafutha ukwanda kunye njengesipholisi.

Kubangela nokuba indlela yokubona kubo

Oonobangela abahluphekayo air-fuel umxube (injector) baxomoloza ezilula elungiselwe kwisithuthi. Baya ungachaza efanayo nge injini uxilongo. Okokuqala zonke phambi iidipozithi ezinjalo ukuba ibonwe nekhandlela. Kuzakubangela umxube ndayame ukuya injector ezinxulumene iziphene kwinkqubo elekhtrons. Lunoxanduva hayi kuphela unikezelo amafutha kwiyunithi lwamandla, kodwa kwakhona ukulungiselela echanileyo umxube air-fuel. Kwimeko enjalo, kusenokuba unengxaki ebeka ubonelelo amafutha okanye umoya. Ngenxa yokuba oku kwenzeka umxube repauperization. Ukusombulula ingxaki lomnini moto kufuneka bafune uncedo lobungcali njenge inkqubo inaliti ukungaphumeleli yanele na iziphoso abenzi boluvo, ukulungiswa ngokungafanelekanga-angle umcephe wokunyusa. Njengokuba kunjalo yentlanganiso ye-firmware kwi iyunithi electronic ukutshiswa ulawulo injini lwangaphakathi. Kuhle ukukhumbula ukuba ukwakhiwa umxube zingatshintsha amanye amanani nje ixesha elifutshane. Kungenjalo, kufuneka ukukhangela le ngxaki kwaye zokuyilungisa.

Kufuneka wenze ntoni xa impazamo

Izizathu ezibhityileyo kwi injector (2110 kubandakanywa) ukuba ngaba ufunyaniswe kwaye lupheliswe ngokuzimeleyo, kodwa kungcono ukuba azigxothe isithuthi kwindawo yokusebenzela ezizodwa apho ukusetyenziswa iza kubamba diagnosis ophezulu ezikumgangatho kwaye ukubona ezinye iimpazamo zisebenza kwisithuthi. Qhagamshelana inkonzo iindleko zesikhululo, kwaye kuba uninzi abaqhubi nje andazi ukulawula ukunyenyisa nokwakhiwa umxube womoya-fuel eziveliswa ngayo. Ngokuqhelekileyo, le iinjini inaliti kunye ipetroli, le umnini moto unalo ithuba lokuba abe. Ngokomzekelo, kufuneka kungabangela kummiselo lokuvula umcephe wokunyusa. Ukuze oku ngokwaneleyo ukutshintsha imeko ring kumise, khosi ihamba phezu vee ezikhethekileyo Iphaphazelisa.

ukuzeyisa

abaqhubi Uninzi bavuyiswa gqitha ukuba uyakwazi ukunyenyisa angle umcephe wokunyusa, njengoko siqiniseke ngokupheleleyo ukuba oku kuza kusenza ulawulo lwemali. Ukongezelela koko, abanye baye babhenela isithuthi electronic iyunithi yolawulo firmware. Ukuze ukuba ukukhubaza ezinye units okanye ECU, kuyimfuneko ukuba bafune uncedo evela iingcibi afanelekayo oya kuba nako ngoncedo lweenkqubo ezizodwa, ngaphandle kokuchaphazela umgangatho umxube, ukuphucula imoto yokusebenza ethile. Kungenjalo, okwandisa ingozi yokuba "obabulalayo" injini yesithuthi sakho. Ngaloo umxube ndayame senziwa injector, unobangela (2114 kungekho ngaphandle) apho ulalelwe self uhlengahlengiso engile okanye ngoncedo umqhubi abangenamava nokusebenza kwenkqubo injini.

Ulungiso inkqubo fuel

Nezinye izinto ezibangela umxube ndayame ukuya injector i ukungasebenzi kwinkqubo kukudla isithuthi. Ngokuqhelekileyo, kukuphazamiseka ngenxa mgangathweni zepetroli, nto leyo sizaliswa isikhululo-kangako igesi. Xa ngobuwena enye, umsebenzi injini ezingazinzanga kunye namahlwempu nomxube Ukwakheka yayanyaniswa kucocwe cell fuel isithuthi. Kwiimeko ezinjalo, kukho okuphumelela injini. Ngenxa yoko, isithuthi jerk. Ukuze uphephe oku, kufuneka ukuthenga amafutha Gas sokukhokhela kuphela. Kufuneka wenze indawo ngexesha zombini iiseli amafutha. Qaphela ukuba filter thaca kwi injector njenge enemingxuma, kwaye ifakwe ngqo kwi impompo amafutha ipetroli. Into yesibini idla kufutshane emazantsi itanki kwisithuthi, ubuncinane - kweli gumbi injini. Ukunqanda repauperization mix, kufuneka itshintshwe ngamakhefu angekho ngaphantsi kwe kanye-40 000 km. Ngamanye amaxesha eli nani ngaphantsi, ekubeni yonke into ixhomekeke kumgangatho zepetroli.

esemzimbeni ugcwale

Ukuba ngaba uchitha ixesha endaweni inkqubo cell amafutha emotweni, kuyaba ingxubevange ahluphekileyo injector, oonobangela eza kuhlawulwa ngo-nemilomo ukungasebenzi. Oko kukuthi, amafutha inikezelwa, kodwa tirhisiwaka umlinganiselo ophantsi ngokwaneleyo. Amanzi esatsiba sisixhobo ekhethekileyo ephathelele kwinkqubo ziphene imoto. Ukwahlula isethi elements: umoya, electrohydraulic okanye pezogidravlicheskaya. On kweenqwelo iinjini ipetroli usebenzisa amalungu kagesi. Isizathu sokuba ukuhluleka ngolu hlobo. Kwamafutha amacebo na kutshintshwa ixesha ixesha uqala ukupasa amafutha kunye kwamagciwane, ngaphandle ukucoca inkcitho esemgangathweni. Ekubeni inaliti umlomo kunye Ekungeneni esatsiba mincinane ngokwaneleyo, amafutha ezinikwa izinto elonakalisayo zangaphandle ukwenza iidipozithi ezindongeni, ngenxa apho amafutha ngoko ubudeki sicatshulwa encinane sinciphile ngakumbi. Ngenxa yoko, i-injini akasinikanga kunye nemali efunekayo amafutha zenzeka iingxaki kunye nomxube abahluphekayo.

Ukusombulula le ngxaki, uyakwazi ukuphatha ngaphandle ekubuyiselweni yangaphambili isitofu ukuhlamba nemilomo, oluqhutywa kuphela kunye nezixhobo ezizodwa.

Ngendlela, ukuba siphephe ezinokosulela okucoca amafutha kunye injectors kufuneka kwenziwe ngaphandle itanki yezibaso kwizithuba ezincinane ecocekileyo, njengoko kukho olwenzeka enkulu ubumdaka, isanti okanye ezinye izinto.

Ezinye izizathu nezisombululo

Le nkqubo baseka amafutha umxube engentlanga injector. Izizathu inokuba nomahluko. Umzekelo, kunokwenzeka ngenxa yobukho kukuvuza emoyeni nento langaphandle, ngoko kufuneka ahlole imibhobho kunye namathumbu ezingenela emoyeni lokucoca ngophawu tight. Esinye isizathu sisenokuba nditshaye otyiwa ngezilingo. Ngenxa yoko, kuya kufuneka wenze endaweni. Indleko yale nxalenye kakhulu eliphezulu. Ukongeza, umoya ukumvumela ukusuka isithuba sensor yamashumi amabini. Kubalulekile ukwenza khangela O-ikhonkco ndawo.

izizathu licaciswe

Ngamanye iimeko, yenzeka ukuba imoto luqokelelane 2107 kwi injector umxube ezinqinileyo, izizathu kakhulu ayaziwa. Ukusebenzisa zokuxilonga ibonisa ubukho kwiimpazamo kunye nomxube amahlwempu, kodwa ayikwazi ukwazi ukuba unobangela ekhokelele ekwakhiweni kwayo. Kule meko kuyimfuneko ukujonga ngequbuliso - ukubona yonke le nkqubo. Okokuqala, izizathu umxube abaziintsizana injector ezinokubangelwa iidipozithi bumdaka yeplagi kokuxhuma, nto leyo ethintela umgangatho injini. Kufuneka kwakhona lokuhlola esatsiba olufanelekileyo indlela umoya. Kuyimfuneko ukuba ageze injector, ekubeni ngenxa mgangathweni zepetroli emadongeni ngaphakathi umfanekiso iidipozithi enamandla carbon. Kweli nqaku mna avavanywa zonke izinto ezinkulu eziphembelela ukuyilwa ezinqinileyo, sivumele umqhubi ukwandisa zexa zabo kwaye akwazi ukulungisa kwezinye iimeko ngokwabo. Ukuba umqhubi abo basandula kuqalisa akuyomfuneko ngaphandle amava ukuyilungisa, kungcono ukuthumela imoto kwi isifo ukuya SRT. Kwaye okona kubalulekileyo - khumbula ukuba nokuphelisa ngexesha le ngxaki iya kwandisa ubomi unit bakho.
