Low-ingcindezi fuel futha yenjini udizili: izici eziyinhloko futhi uya khona

injini yemoto ngokuvamile kuqhathaniswa inhliziyo yomuntu. Futhi ifana ezithile ngempela. Ngenxa inhliziyo Umuntu angaphila, sibonga imoto motor - ukuhambisa. Inhliziyo iphampa igazi emzimbeni - kuqinisekisa ukusakazwa kwalo zonke izitho ukhiye. Ngo injini eyenza umsebenzi onjalo uhlelo nophethiloli. Lamuhla sitawubuka izici ngenhloso futha ephansi kwengcindezi. Lo msuka uyingxenye ebaluleke kakhulu ohlelweni amandla. TNND ezidingekayo ukuze awunikeze uphalafini futha nophethiloli. Ngokuvamile lifakwe eduze futha. Bobabili izindlela axhunyiwe esebenzisa amapayipi okuyothi kwegazi. Ngasikhathi sinye, nophethiloli sidlula izihlungi lapho bahlanza.

Yiziphi izinkinga isixazululekile TNND ohlelweni fuel

Low-ingcindezi fuel futha yenjini udizili ukuzixazulula inkinga ebalulekile. Okokhelekayo, okuyinto sidla ngaphansi kwengcindezi ongaphakeme, kweyame abilayo. Ngenxa yalokho emaphaketheni umusi akhiwa. Umusi abagcwele semikhawulweni ukukhanya nophethiloli mkhulu abahlukene. Lokhu kusho ukuthi ongaphakeme ingcindezi futha uqala uketshezi kabani viscosity kushintsha njalo. On umjovo fuel Nokho usebenzisa uphethiloli umjovo futha kule mode evamile,. Ithoshi kushintsha njalo futhi ngeke ukuwela imingcele evamile.

TNND kanjani

I futha kukawoyela injini diesel yakhiwa low-ingcindezi drive kushaft. Ukudonswa kwalawo manzi wenziwa nge Rotor ekhethekile lapho kukhona izindwani. Futhi e ukwakhiwa kwalesi stator inikezwa, usabalalisa disc futhi idrayivu igiya. Lapho Rotor is actuated, kuziwa eduze izindwani stator. Khona-ke, ukwakheka amakhamera ngenxa amandla centrifugal. Kusukela ku ingaphakathi futha adalwe voltage enikeziwe kusukela fuel ngqo fuel ukumpompa kubo. Ukuze wenze lokhu, kukhona iziteshi kudiski wokusabalalisa. Umqulu elincane udizili ziyowa valve ukunciphisa, uma ngizwa ingcindezi ingaphezu kunesidingo. Bobabili amadivayisi oxhumene, ngakho yokwakha kanye nokugcina izimo adingekayo isicelo abakhwabanisi binda ekhethekile. Lokhu jet, okuyinto screwed ku futha ephezulu ingcindezi. Ngakho, izimo badalwe emakamelweni ngokuya ngesivinini ngawo idrayivu shaft uzungeza.

Ukulekelela futha apharathasi

I futha booster noma ingcindezi ongaphakeme fuel (TNND) e diesel amandla amayunithi likwazi isakhiwo esilula. Siqukethe namasondo amabili igiya, okuyizinto unomphela ukubandakanyeka nomunye. Phakathi Ukujikeleza, namazinyo lezi amagiya ukudala ukugeleza nophethiloli ngokusebenzisa uhlelo uphalafini futha umfutho ophakeme. The main ilungu ezihlelekile futha-futha - piston okuyinto sifaka nophethiloli. Ukuze unikeze injini diesel kufanele kube ezimbili izindlela okusebenzela kuyo piston. Lokhu unhlangothi nokusekelwa.

izinhlobonhlobo TNND

Okokhelekayo ingcindezi ongaphakeme futha yenjini udizili - lena eyodwa kuphela uhlobo lezi zinhlelo. Ngaphezu kwalokho udizili, kungenziwa lezi amadivaysi ezitholakala nakwezinye izinjini, kungakhathaliseki imodeli injini noma ngonyaka zokukhiqiza. Ngaphandle futha ukuzenza - kubalulekile ukuthi unikezele uphethiloli uphethiloli kanye nokudlulisela ke eminye kanye ohlelweni. Endabeni izinjini umshini emotweni lapho kuhlanganiswa khona umoya nomusi kaphethiloli likaphethiloli asetshenziswa kuqhathaniswa buthakathaka amandla amaphampu lokukhanda. On amayunithi ifakwe amandla uhlelo injector kanye diesel amandla amayunithi usebenzisa udizili kagesi booster futha.

TNND mechanical

Lolu hlelo igibele ngqo ku block isilinda futhi fixed esebenzisa nezikulufi abavamile. Ukusebenza kwalesi futha inikezwa esebenzisa crankshaft nge ome njengeqanda. Uma uchofoza cam ome njengeqanda, ngaphakathi ukusikeka wadala. Kusukela fuel wumnikezeli uhlelo ugesi. Ukuze ubuyele fuel akusho hit, futha ifakwe Isivalo esikhethekile. Ezinye izindaba zika-cam ngokucindezela ukuthumela uphethiloli kuya carburetor. Uma imoto ifakwe TNND uhlobo mechanical, khona-ke kulula ukuqala injini, ngisho ne-akhawunti eside kumile. Ukuze wenze lokhu, mane nje ngesandla ukumpompa uzotshala indlela.

kagesi

On izimoto zanamuhla zisebenzisa uphethiloli kagesi ingcindezi ongaphakeme futha yenjini diesel injini uphethiloli umjovo. Ukusetshenziswa idivayisi mechanical kwaba akunakwenzeka. Yena kungenxa yamandla ephansi, hhayi ukubhekana imisebenzi. Akukona ukudala ingcindezi oyifunayo ngaphakathi ohlelweni nophethiloli. Ifomu okulula zedivayisi liyisici futha uqobo futhi i motor ngogesi ebiyelwe zezindlu olulodwa. Kukhona futhi isihlungi wokuhlanza fuel, uphethiloli eyanele kanye inzwa fuel ukugeleza. Ukushayela futhi ezisebenza isimiso esifanayo ukuze algorithm for ukusebenza kwamandla iyunithi. Umahluko owokuthi ukuthi motor kagesi isetshenziswa ukumpompa uketshezi. Ngo uphethiloli izinjini TNND isebangeni ngokuqondile ngaphakathi uphethiloli. Abanikazi Iningi imoto bakholelwa ukuthi kungcono akuphephile. Eqinisweni, akukho ngozi ngalolo. Endabeni uphethiloli fuel ngaphakathi futha ivame ukuba overheat ngenxa ukufudumeza, okuyinto kudedela injini. On the analogs kagesi inkinga enjalo engekho nhlobo. Okokhelekayo ihamba ngaphandle kokuphazamiseka wesistimu Imibhobho esemzimbeni futhi futha akusho kuphole iphuzu ezibucayi. Ngo izinjini udizili kagesi TNND ngokuvamile kuhlanganiswe futha umfutho ophakeme. Lokhu zingachazwa ngezinqubo isidingo ukunikeza uphethiloli njalo. Lokhu kuqinisekisa operation esitebeleni of injini, aphenduka ngejubane elingafani.

Umfutho ophakeme fuel futha (fuel futha)

Le divayisi ubhekwa omunye eziyinkimbinkimbi kakhulu injini diesel. umsebenzi Its main - ukuqinisekisa ukugeleza udizili ekamelweni omlilo ngaphansi kwengcindezi okusezingeni eliphezulu. Okuphakelayo inikezwa hhayi kuphela ngaphansi kwengcindezi ethile, kodwa isikhathi esidingekayo. Khonza ngokunembile kakhulu alinganisiwe ngekhompyutha futhi ngokugcwele oluhambisana umthwalo iyunithi. Kunezinhlobo eziningana fuel injection uhlobo amadivaysi. Lokhu aqoqa nge accumulator umjovo uhlelo kanye ngokunyakazisa ngqo. Iinsetjenziswa umjovo futha yenjini udizili, esisetshenziselwa isimiso ukusebenza ngqo, ungachazwa ukuthi umklamo sisetshenziswa le plunger, enikezwe mechanical uhlobo actuator. Ngakho, umjovo kanye umjovo kuyenziwa ngesikhathi esisodwa. Endabeni ngayinye egumbini amandla omlilo ingxenye ehlukile ye futha atomizes umthamo uphethiloli. Ingcindezi iyadingeka bunikezwa ukuhamba indlela plunger.

futha elishajekayo kanye nezici zabo

Amaphampu anemisila ibhethri-umjovo, kukhona ukungezwani phakathi kwakho. Ngakho, ukusebenza plunger actuator ezosebenza amagesi ecindezeleke ngaphansi kwengcindezi phakathi amasilinda injini. Futhi, ukuchayeka kungenziwa ngezincwadi iziphethu. amadivaysi Manje ezivamile ezifana accumulator wokubacindezela. Basuke ukufakwa ephezulu amandla motors, ukusebenza ikakhulukazi ngesivinini aphansi.

I eziyimbangela yezinkinga ezizuzwa eziyisisekelo TNND

Inkinga eyinhloko - ukwehla idivayisi ukusebenza ungqimba iconsi umjovo, esinikela low-ingcindezi fuel futha yenjini udizili. Kungenzeka ukunquma esebenzisa manometer noma ingcindezi gauge, okuyinto efakwe emnyango. umkhiqizo Ngokuvamile kubangelwa elahlekile kuyinto TNND odla kanye Jamming yelunga msebenzi. Ngokuphathelene isizathu sokuqala, e udizili kungase aqukethe ukungcola ezihlukahlukene okuthi lanxa edabula izakhi lemifanekiso, nokho namanje buthelela valve. Kungenzeka futhi ukuthi kwehle kuyaqina timphawu ukubuya entwasahlobo.

Indlela ukulungisa TNND

Uma nekusebenta iyunithi lehlile, kusho udizili fuel futha ingcindezi ongaphakeme futhi kumelwe kususwe ipolitiki. Ngokuvamile ukusebenza futhi liphume ngemva ngamanzi futhi yokuhlanza izimbotshana ukusebenza futhi izakhi zedivayisi. Futhi, kuyasiza likhanyelwe futhi resin udoti kusuka amanzi linezingxenye. Ukuze esibi kakhulu ukulungisa usebenzisa ukulungisa kits seziyatholakala ku namafemu Chinese ezikhiqiza izingxenye for imoto izinjini.

Ukwazi indlela ephansi kwengcindezi fuel futha yenjini udizili, isimiso ukusebenza idivayisi, kungaba ukulungiswa noma ukushintshwa kalula.
