Ukufakwa futha yenjini udizili. High-ingcindezi fuel futha

Umehluko omkhulu kusukela diesel, nophethiloli uyindlala enye idivayisi kohlelo fuel nophethiloli umjovo uhlelo. Abantu yibona ababaluleke kakhulu ekuklanyweni futha fuel injection yenjini udizili. Lokhu futha fuel a umfutho ophakeme.

Kuyini futha fuel

Lokhu imishini ubhekwa omunye owaba umqansa kunayo yonke phakathi kwezinye izingxenye udizili powertrains. Idivayisi yenza umsebenzi oyinhloko. It wayihambisa fuel ekamelweni omlilo ngaphansi enomfutho. Kuyadingeka ukuba unikeze ingxube ezivuthayo ekamelweni omlilo kwengcindezi elinqunyiwe, futhi esifanele salokhu. Ingxenye ifidi ngokunembile kakhulu kulinganiswa ngekhompyutha. Futhi, ingxenye elihambisana umthwalo.

Evolution futha

Ohulumeni emazweni amaningi kakhulu some iziqondiso kwemvelo ku ekushayweni izinto eziyingozi. Lokhu kwaholela yokuthi mechanical fuel futha udizili waqala ukuba kancane kancane sithathelwe indawo zikagesi. Mechanical ukubhekana nokushintsha kokudla nokufakwa lesifanele ingxube fuel ukuze ukunemba okunjalo. Ngaphezu kwalokho, Mechanics ayikwazanga asabela ngokushesha zonke ushintsho imodi esebenzayo samandla iyunithi.

Electronics abakhiqizi eyaziwa kakhulu ukunikela eziphambili elawula uhlelo ukusuthisa ingxube nophethiloli. Ukwethulwa kwe-electronics ukuvumele ukunciphisa amafutha omlilo kokuntengantenga kwezomnotho, futhi yehlise non-ukufana idling.

Amanye amadivayisi ube isakhiwo sabo valve esikhethekile isinyathelo ngokushesha. Lokhu kwaholela ekutheni inqubo ngokuhlukana yokondla ingxube fuel ekamelweni zibe izingxenye ezimbili. Le ubuchwepheshe ukunciphisa kakhulu amandla omlilo rigidity.

Ukunemba ukuphathwa umjovo uyophinde ukunciphisa kwekhabhoni ezinobuthi. Ngo izinjini ezintsha ingxube ubashisa ngokuphelele, futhi akhule kahle lithuthukile kahle futhi ukwandisa amandla kokugcina.

Electronic imishini elawulwa ifakwe uhlobo wokusabalalisa. Electronics ulungisa yokuma dispenser. Futhi iyatholakala njengengxenye valve akhethekile elikuvumela ukuba sigweme ukuphinda osekushiwo inqubo umjovo.

izinhlobo zikaphethiloli futha

Kunezinhlobo eziningana fuel injection amaphampu yohlobo. Ngokwesibonelo, kukhona kumadivayisi we isinyathelo esiqondile, kanye nebhethri-imishini. Esikhathini mzuzu lokugcina simiso ukulungiswa izinqubo babelwa ngqo injectors nokulawula izinhlelo elekthronikhi.

oqondile isinyathelo futha

Ukufakwa futha yenjini udizili, ngokunyakazisa ngqo has a idivayisi lokukhanda. Ukuhamba kusekelwe plunger kanye emkhonweni. Lokhu kubizwa ngokuthi i-pair plunger. Noma yimuphi izinqubo imishini yalolu hlobo zenzeke ngesikhathi esisodwa. Ngo omlilo ngamunye ekamelweni injini diesel ingxenye ehlukile ye futha eletha uphethiloli ku umthamo edingekayo. Ngokuqondene ingcindezi, kwakha ukunyakaza futha plunger. Lokhu imishini ifakwe ezihlukahlukene udizili izimoto. Futhi ihlangabezana udizili fuel injection futha ( "Volkswagen" - iyathinteka) ngalendlela.

futha ibhethri

Lapha, ngokungafani futha owandile wokuthi izenzo phezu plunger yokucindezela actuator ngqo uMbhalo. Kodwa ngaphandle kwalokho, umphumela onjalo kungenzeka ngezincwadi iziphethu ekhethekile. Kukhona futhi amadivayisi nge accumulator wokubacindezela, okuyinto asethwe ikakhulukazi enamandla, kodwa malooborotistye izinjini.

Kufanele wathi, nge accumulator amaphampu kukhona kuzinqubo ezihlukile, umjovo kanye khulula. Ingxube ezivuthayo akhishwa ngaphansi kwengcindezi ephakemeyo bangena accumulator bese ingena egumbini amandla omlilo. Le ndlela ivumela a sishaye ngempumelelo ngaphezulu, kanye kwemisebenzi yoMnyango ingxube ekwakhekeni, okuyinto uphelele zonke izinhlobo imithwalo. Phakathi bokwenza njalo kwesimiso esinjalo bungabonakala eyinkimbinkimbi nakakhulu imishini ukuthi ungakuvumeli ukuba ukuthandwa. Ngo izinjini yesimanje imishini ukusetshenziswa esekelwe valve Solenoid nokulawula uhlelo electronic.

ukusatshalaliswa futha

Lezi zici, kunalapho okusemgqeni, ifakwe eyodwa noma ezimbili plungers ukuthi ukukhonza yonke egumbini amandla omlilo. Isisindo kanye Ubukhulu yalezi amadivaysi kakhulu ukubuyeka. Izinga eliphakeme lomsebenzi wabo ngesikhathi esifanayo iphezulu kakhulu. Kodwa lezi izinhlelo zinezikhathi ukuqina ongaphakeme. Ngokuvamile zidinga ukulungisa umjovo futha diesel. It likhombe ukusetshenziswa imishini - izimoto.

uxhumekile kwi-inthanethi amaphampu

Lokhu imishini ifakwe ngazimbili plunger. Njengoba abaningi njengoba amasilinda e injini. Imininingwane lezi aboshelwe emalokishini, lapho kukhona iziteshi esikhethekile ukudonsa nokususwa diesel. Ukushayela ku ukuhamba plunger osebenza a cam kushaft ekhethekile okuyinto eliqhutshwa crankshaft. I futha usebenza, izakhi futha kufanele agxishiwe ngokumelene Cams. Lokhu luyasetshenziswa esebenzisa iziphethu.

Lapho shaft cam ihamba, le cam ivuliwe tappet, okuyinto okwamanje ihamba emikhonweni yayo. Lapho isici ukunyakaza ikhiqizwa izimbobo ukuvulwa kanye lokuvalwa itheku nophethiloli yokuxhuma. Ngakho, ingcindezi ohlelweni livela. Ngenxa yalokho, i-valve umjovo zivulwa nophethiloli ezihambayo agudle uphalafini injectors. Lona umsebenzi we udizili fuel injection futha.

Ukuze ulungise plunger ijikeleziswa esikhwameni saso. Ukuze wenze lokhu, ukulula apharathasi has a gear olukhethekile okuyinto ekubambisaneni ne yokubeka. Mithandazo exhumene ngokuqondile isinyathelo namafutha. Ingxenye engenhla plunger senziwa ezintweni ezingafanele. Uma ukushintshanisa, ungakwazi ukushintsha inani diesel.

Lo mklamo avunyelwe futha umugqa ukunikeza enokwethenjelwa. Tindlela nivame amafutha engine kusukela ohlelweni Lubrication unit. Ngakho-ke kungenzeka ukusebenzisa ngokwanele ongaphakeme fuel izinga. Lezi kusetshenziswa amaphampu ngamaloli amakhulu, nezimoto yasetshenziswa kuze 2000.

Idivayisi ye udizili fuel injection futha

Ngo kudivayisi futha Isibonelo raspreditelnogo kungase kubhekwe njengokuvamile ayisisekelo. Ngakho, amaphampu kukhona odnoplunzhernymi noma dvuhplunzhernymi. Kulokhu omunye ingxenye apharathasi kungase afeza ingxube ezivuthayo ka Imibhobho esemzimbeni eziningana.

Ngakho, imishini siqukethe ingcindezi ukwehlisa valve, variable speed Regulator of itjhubhu abakhwabanisi, futha kwesigaba izindlu nge plunger kanye pair of valve. Ngaphandle kwalokho, njengoba ingxenye amadivayisi liyisici for uzotshala fuel, dweba for ukulungisa kusengaphambili umjovo, emzimbeni, Solenoid kudivayisi valve kanye plunger drive.

Njengoba singabona, imishini has a idivayisi eziyinkimbinkimbi. Uma kwenzeka ukuwohloka ukuhlola umjovo futha yenjini udizili ngeke kube umsebenzi onzima. Uhlelo ukulungisa ngisho egalaji kuyoba nzima kakhulu.

Izimbangela amaphutha

Izindleko yalezi amadivaysi kuqhathaniswa okusezingeni eliphezulu, futhi futha efunwa kakhulu kuya izinga amafutha kanye igrisi. Uma imoto udizili ukusebenziswa fuel okubi, khona-ke ngempela iqukethe ezihlukahlukene ukudla okuqinile. Konke lokhu kuthinta ukusebenza zenhlangano plunger, okuyinto has a ukubekezelelana ubuncane. Futhi, yekhwalithi ephansi "diesel" zilinyazwa kalula Imibhobho esemzimbeni. Banikezwe yinkimbinkimbi yesimanje udizili fuel injection futha, intengo ephansi izinga uphethiloli ukugcwaliswa kungaba eqolo. By the way, futha ngokwayo kubiza cishe u- $ 300.

Phakathi iloli ethandwa kakhulu ukumpompa futhi injectors Ulandela:

• ekusetshenzisweni kakhulu;
• wakuthunqisa e-qeda;
• umsindo nezinye imisindo nezingahlobene nendaba;
• ukunqabela emandleni;
• Ukuqala kuyinkimbinkimbi.

Ngokwemvelo, umonakalo kungadalwa ezinye izizathu. Futhi ubone uma umjovo ukulungisa futha diesel adinga ukuma ekhethekile kuyadingeka. Lokhu imishini itholakala kuphela iziteshi, okuyinto ngokukhethekile imishini efanayo. amaphampu Modern akudingeki izidumbu zabantu ukulungiswa, esizokwenza ukuxilonga. Ngakho kufanele sizinike ngosizo ochwepheshe.

ukulungiswa umshini

Isidingo ukulungiswa kungadalwa yezizathu ezihlukahlukene. amaphutha amaningi kungenakususwa ngesandla. Nokho, uma ukulungisa kuyehla kube esikhundleni izingxenye bakhathale, lokhu kalula kwenziwa egalaji. Kodwa ukulawula imishini ngeke kusadingeka othini ozinikele.

Ngakho, esinye sezizathu - wegazi ophezulu futha we wear udizili. Nquma lokhu ngempela kalula. Sokuphehla amandla izosebenza engalingani kakhulu futhi elikhulu. Futhi nzima ngokuqala futhi ukulahlekelwa amandla. Pro ukhwaliti ongaphakeme fuel isivele wathi. Okuningi ku ukuseviswa kuthinte electronics. Ukuze ukulungisa ngokuvamile nje esikhundleni ukuthi zigugile. Kodwa lokhu kuyadingeka ukuqaqa idivayisi. Lokhu kungenziwa ngezandla zakhe, kodwa ngaphandle kolwazi efanele kungcono ukuba baphendukele ochwepheshe.

Ngakho, lapho sathola khona ukuthi kukhona izinhlobo ephezulu ingcindezi fuel amaphampu kanye kubhekwe izizathu ukwehluleka kwabo.
