Isebenza kanjani i-carburetor ohlelweni lukaphethiloli?

I-carburetor inesibopho sokuxuba uphethiloli nomoya ngenani elifanele futhi inikeze le ngxube kumasilinda. Yize bengekho ezimotweni ezintsha, ama-carburetors aletha uphethiloli ezinjinini ...

Umshini weSlot carburetor obhekene nokuhlanganisa uphethiloli nomoya ngenani elifanele futhi unikeze le ngxube kumasilinda. Nakuba engasetshenziswa ezimotweni ezintsha, ama-carburetors aletha uphethiloli ezinjinini zemoto ngayinye, kusukela ezimotweni zomjaho ezidumile kuya ezimotweni eziphambili. Zasetshenziswa e-NASCAR kwaze kwaba ngu-2012 futhi abathanda izimoto eziningi zakudala basebenzisa izimoto ezinamakhabhurethi njalo ngosuku olulodwa. Ngabantu abaningi abathanda izimoto, ama-carburetors kumele anikeze okuthile okukhethekile kulabo abathanda izimoto.

Isebenza kanjani i-carburetor?

I-carburetor isebenzisa i-vacuum eyenziwe injini ukuze inikeze umoya nophethiloli kumasilinda. Lolu hlelo selusetshenziswe isikhathi eside ngenxa yobulula balo. mpintsha ingavuleka futhi ivale, ivumele umoya omncane noma omncane ukuthi ungene enjinini. Lo moya udlula endaweni ewumngcingo ebizwa ngokuthi imisebenzi. I-vacuum ingumphumela wokugeleza komoya okudingekayo ukugcina injini isebenza.

Ukuze uthole umbono wokuthi i-venturi isebenza kanjani, cabanga ngomfula ogeleza ngokuvamile. Lo mfula uhamba ngesivinini esingaguquki futhi ukujula akuguquki kakhulu kuwo wonke. Uma kunengxenye encane kulo mfula, amanzi kuyodingeka asheshise ukuze umthamo ofanayo udlule ekujuleni okufanayo. Uma umfula usubuyele ebubanzini bawo basekuqaleni ngemva komgodi webhodlela, amanzi asazozama ukugcina isivinini esifanayo. Lokhu kubangela amanzi esivinini esiphezulu ohlangothini olukude lwe-bottleneck ukuheha amanzi asondela emgodini webhodlela, okwenza i-vacuum.

Ngenxa yeshubhu le-venturi, kune-vacuum eyanele ngaphakathi kwe-carburetor ukuze umoya odlula kuyo uhlale udonsa igesi ku-carburetor. indiza. I-jet itholakala ngaphakathi kwe-Venturi tube futhi iyimbobo lapho uphethiloli ungena khona igumbi lokuntanta ingaxutshwa nomoya ngaphambi kokungena kumasilinda. Igumbi lokuntanta libamba uphethiloli omncane njenge-reservoir futhi livumela uphethiloli ukuthi ugeleze kalula ku-jet njengoba kudingeka. Uma i-throttle valve ivuleka, kudonswa umoya omningi enjinini, okuletha uphethiloli owengeziwe ngawo, okwandisa amandla enjini.

Inkinga enkulu ngalo mklamo wukuthi i-throttle kumele ivuleke ukuze injini ithole uphethiloli. I-throttle ivaliwe ngokungenzi lutho, ngakho indiza engenzi lutho ivumela uphethiloli omncane ukuthi ungene kumasilinda ukuze injini ingami. Ezinye izinkinga ezincane zihlanganisa umhwamuko kaphethiloli oweqile ophuma egunjini le(ama)gumbi lokuntanta.

Kuhlelo lwamafutha

Ama-carburettor enziwe ngezindlela ezahlukahlukene nosayizi phakathi neminyaka. Izinjini ezincane zingasebenzisa i-nozzle eyodwa kuphela ye-nozzle carburetor ukunikeza uphethiloli enjinini, kuyilapho izinjini ezinkulu zingasebenzisa imibhobho efinyelela kwayishumi nambili ukuze ziqhubeke zinyakaza. I-tube equkethe i-venturi ne-jet ibizwa ngokuthi umgqomo, nakuba leli gama livame ukusetshenziswa kuphela ngokuphathelene multi-barrel carburetors.

Esikhathini esedlule, ama-carburetor anemigqomo eminingi abe inzuzo enkulu ezimotweni ezinezinketho ezifana nokulungiswa kwe-4- noma 6-cylinder. Lapho imiphongolo eminingi, umoya nophethiloli wawungangena kula masilinda. Ezinye izinjini zize zasebenzisa ama-carburetor amaningi.

Izimoto zezemidlalo zazivame ukuvela efekthri zine-carburetor eyodwa isilinda, okwethusa omakhenikha bazo. Konke lokhu kwakudingeka kushuniswe ngazodwana, futhi izigxivizo ezinamandla (ezivamise ukuba isiNtaliyane) zazizwela kakhulu kunoma yikuphi ukungapheleli kokulungisa. Futhi babevame ukudinga ukushuna kaningi. Lesi yisizathu esiyinhloko sokuthi umjovo kaphethiloli waqala ukuthandwa kakhulu ezimotweni zezemidlalo.

Ashonephi wonke ama-carburetor?

Kusukela ngawo-1980, abakhiqizi bebelokhu bekhipha ama-carburetor bethanda umjovo kaphethiloli. Zombili zenza umsebenzi ofanayo, kodwa izinjini zesimanje eziyinkimbinkimbi zivele zavela kuma-carburetors ukuze zithathelwe indawo umjovo kaphethiloli onembe kakhulu (nokuhleleka). Kunezizathu eziningana zalokhu:

• Umjovo wesibaseli ungaletha uphethiloli ngokuqondile kusilinda, nakuba umzimba we-throttle ngezinye izikhathi usetshenziselwa ukuvumela i-injection eyodwa noma amabili ukuletha uphethiloli kumasilinda amaningi.

• Idling kunzima nge-carburetor, kodwa kulula kakhulu ngama-injection fuel. Lokhu kungenxa yokuthi isistimu yomjovo kaphethiloli ingavele yengeze inani elincane likaphethiloli enjinini ukuze iqhubeke isebenza ngenkathi i-carburetor ine-throttle ivaliwe ngokungenzi lutho. I-jet eyize iyadingeka ukuze injini ye-carburetor ingagcini lapho i-throttle ivaliwe.

• Umjovo wamafutha unembe kakhulu futhi udla uphethiloli omncane. Ngenxa yalokhu, kukhona futhi umhwamuko omncane wegesi ngesikhathi sokujova uphethiloli, ngakho mancane amathuba omlilo.

Nakuba isiphelelwe yisikhathi, ama-carburetor enza ingxenye enkulu yomlando wezimoto futhi asebenza ngokuzenzakalelayo nangobuhlakani. Ngokusebenza ngezinjini ezifakwe ama-carbureted, abashisekayo bangathola ulwazi olusebenzayo lokuthi umoya nophethiloli kunikezwa kanjani enjini ukuze ikokhele futhi iqhubekisele phambili.
