ukwephulwa kwe-carburetor

Umsebenzi we-carburetor ukukhiqiza ingxube efanele (ingxenye engu-1 kaphethiloli nezingxenye ezingu-16 zomoya). Ngalesi silinganiso, ingxube ivutha ngokuphumelelayo, futhi injini yomlilo yangaphakathi isebenza ngamandla amakhulu. Lapho kuvela ukuwohloka kokuqala kwe-carburetor, injini iqala ukugxuma, ijubane elingasebenzi liyanyamalala noma ukusetshenziswa kukaphethiloli kuyanda. Ukunquma imbangela yokuphazamiseka kungaba nzima, ngakho-ke cabanga ngezimpawu eziyinhloko zokungasebenzi kahle.

Izimpawu zokwehluleka ohlelweni lukaphethiloli

Ukuba khona kokwehluleka okungenzeka ekusebenzeni kwesistimu yamandla emoto kungahlulelwa ngezimpawu zokuziphatha kwemoto emgwaqeni:

• Ukwehluleka - lapho ucindezela i-pedal "igesi", imoto iyaqhubeka nokuhamba ngesivinini esisheshayo (noma ngokunciphisa) isikhathi esifushane (kusuka kusekhondi eli-1 kuye kwengama-30), futhi ngemuva kwesikhashana iqala ukukhetha. isivinini;
• I-Jerk - ifana nokwehluleka, kodwa ihlala isikhathi esifushane;
• Ukugubha - ukucwiliswa ngezikhathi ezithile;
• I-twitch uchungechunge lwezijezi ezilandelanayo;
• Ukusheshisa okuvilaphayo izinga elincishisiwe lokunyuka kwejubane lemoto.

Ngaphezu kwalokho, ungakwazi ukwahlulela ukuba khona kokungasebenzi kahle ohlelweni lwamandla enjini evuthayo ngezimpawu ezilandelayo:

• Ukwenyuka kokusetshenziswa kukaphethiloli;
• Ukuqala kwenjini yomlilo yangaphakathi akusebenzi;
• Ijubane elincishisiwe noma lenyukile lokungenzi lutho;
• Ubunzima benqubo yokuqala injini yomlilo yangaphakathi eshisayo / ebandayo;
• Ukusebenza okunzima kwenjini yomlilo yangaphakathi yemoto esebenza kwimodi ebandayo.

Indima enkulu idlalwa yisimo sobuchwepheshe senjini ICE.

Izinguquko ezigabeni zokusatshalaliswa kwegesi, ukuguga kwamakhamera e-camshaft, ukulungiswa okungalungile kwezikhala zokushisa, ukucindezelwa okuncishisiwe noma okungalingani kumasilinda, nokushiswa kwama-valve kunciphisa kakhulu amandla emoto, kubangela ukudlidliza nokwandisa ukusetshenziswa kukaphethiloli.

i-carburetor kanye nokuwohloka kwayo nakho kudlala indima ebalulekile. Cabangela ukuwohloka okuvame kakhulu kwe-carburetor usebenzisa i-Solex njengesibonelo. Indlela yokuhlanza kahle, hlola futhi ulungise i-carburetor, usebenzisa i-VAZ 2109 njengesibonelo, kuchazwe esihlokweni. Ngakho.

Uma iqembu le-cylinder-piston ligugile, amagesi e-crankcase, umusi kawoyela kanye namagesi e-tarry nawo angangena endaweni ye-carburetor, avale into yokuhlunga, futhi ahlale kumajethi nezinye izakhi ze-carburetor, ngaleyo ndlela aphazamise ukusebenza kwenjini yangaphakathi evuthayo.

Ukwehluleka okujwayelekile kwe-carburetor

Uma injini evuthayo yangaphakathi ingaqali noma izitebhisi ngokushesha ngemva kokuqala. Mhlawumbe lokhu kungenxa yokuthi awekho amafutha ekamelweni le-float noma ukwakheka kwengxube kuphazamiseka (isibonelo, ingxube icebile kakhulu noma ngokuphambene nalokho).

I-ICE uma ingenzi lutho ayizinzile noma iyahlala njalo. Ngokusebenza okulungile kwezinye izinhlelo ze-carburetor, ukuwohloka okwengeziwe kungenzeka ngenxa yalezi zici ezilandelayo:

• Iziteshi ezivaliwe noma amajethi angasebenzi;
• Ukungasebenzi kahle kwe-valve solenoid;
• Ukungasebenzi kahle kwezakhi ze-EPHH neyunithi yokulawula;
• Ukungasebenzi kahle nokusonteka kwendandatho yokufaka uphawu lwenjoloba - isikulufa "sekhwalithi".

Njengoba uhlelo loguquko lwegumbi lokuqala lusebenzisana nesistimu yokugijima ebandayo, ngesivinini esiyingxenye, ukwehluleka kungenzeka, futhi ngezinye izikhathi ngisho nokuma okuphelele kwenjini yomlilo yangaphakathi ngesikhathi sokuqala kwemoto. Ngokukhukhula noma ukuhlanza iziteshi, ukuvinjelwa kungaqedwa, kodwa kuzodinga ukuhlakazwa kancane. udinga futhi ukushintsha izingxenye ezinephutha.

Ijubane elingenzi lutho

Ukungenzi lutho okuphansi/okuphezulu kungase kubangele:

• Ukulungiswa kokungenzi lutho okunephutha:
• Izinga elincishisiwe / lenyukile likaphethiloli ekamelweni;
• Umoya ovalekile noma amajethi kaphethiloli;
• Ukumuncwa umoya-mpilo epayipini lokungena noma i-carburetor ngamapayipi axhumayo noma emajoyintini;
• Ukuvuleka kwengxenye ye-air damper.

Ukusebenza okungazinzile kwenjini evuthayo yangaphakathi kungabangelwa ukulungiswa okungalungile kwengxenye yengxube.

Ukuqala okunzima kwenjini evuthayo yangaphakathi nokusetshenziswa kukaphethiloli

Ubunzima bokuqalisa injini ebandayo kungabangela ukulungiswa okungalungile kwendlela yokucupha. Ukuvala ingxenye ye-damper yomoya kungabangela ingxube ukuba ibe ncane, okuzobangela ukungabikho kokukhanya kumasilinda, futhi ukuyivula ngokungalungile ngemva kokuqala injini yomlilo yangaphakathi inothisa ingxube ngokwanele, ngakho-ke injini yomlilo yangaphakathi "ixube" .

Ubunzima bokuqalisa imoto lapho injini ifudumele kungase kubangelwe ukuthi ingxube ecebile ingena kumasilinda ngenxa yezinga eliphezulu likaphethiloli elisendlini yokuntanta. Isizathu salokhu singase sibe ukwephulwa kokulungiswa kwegumbi likaphethiloli noma i-valve yamafutha ayivalwanga kahle.

Ukusetshenziswa kukaphethiloli ngokweqile. Ukuqeda lesi "sici" kunzima kakhulu, njengoba kungabangelwa izizathu ezihlukahlukene. Ekuqaleni, kufanelekile ukuqiniseka ukuthi akukho ukumelana okwenyukayo kokuhamba kwemoto, okwenziwa lula ngamabhuleki ezigubhu noma ama-disc, ukwephulwa kwama-engeli akhuphuka amasondo, ukuwohloka kwedatha ye-aerodynamic lapho uthutha impahla enkulu ophahleni, noma ukulayisha imoto. Isitayela sokushayela siphinde sibe nendima ebalulekile.

1, 4, 13, 17, 20 - izikulufo ezivikela ikhava ye-carburetor emzimbeni; I-2 - i-diffuser encane (i-spray) yesistimu ye-dosing eyinhloko yekamelo lesibili; 3 - i-atomizer ye-econostat; I-5 - i-air jet yesistimu yenguquko yekamelo lesibili; 6, 7 - amapulaki eziteshi ze-econostat; 8, 21 - izimbobo zokulinganisa zegumbi le-float; 9 - i-axis ye-damper yomoya; 10, 15 - izikrini zokubopha i-damper yomoya; I-11 - i-diffuser encane (i-spray) yekamelo lesibili; I-12 - i-air damper; I-14 - isiteshi se-air jet eyinhloko yekamelo lesibili; I-16 - isiteshi se-air jet enkulu yekamelo lokuqala; 18, 19 - amapulaki eziteshi ezingenzi lutho; 22 - isifutha sepompo ye-accelerator

Ukwephulwa kokusebenza kwe-carburetor kungaholela ekusetshenzisweni kukaphethiloli okuphezulu:

• ukuwohloka kohlelo lwe-EPHH;
• Izindiza zomoya ezivalekile;
• Ukuvalwa okuxekethile kwe-valve ye-solenoid (ukuvuza kukaphethiloli phakathi kwezindonga zesiteshi kanye nejethi);
• Ukuvulwa okungaphelele kwe-air damper;
• Amaphutha e-Economizer.

Uma ukusetshenziswa kukaphethiloli kukhuphuke ngokumelene nesizinda somsebenzi wokulungisa i-carburetor, kungenzeka ukuthi baxube noma bafake amajethi anembobo enkulu ngokwanele ukuze alungiswe.

Ukucwiliswa okujulile ekumisweni okuphelele kwenjini evuthayo yangaphakathi enevalvu evulelekile ye-throttle yegumbi elilodwa kungase kuqaliswe ukuvaleka kwendiza enkulu yamafutha. Uma injini yomlilo yangaphakathi yemoto ingasebenzi noma isesimweni semithwalo engasho lutho, ukusetshenziswa kukaphethiloli kwenjini yomlilo yangaphakathi kuncane kakhulu. Ukuzama ukufaka imodi yokulayisha egcwele, ukusetshenziswa kwe-fuel mass kukhula kakhulu, akukho patency eyanele yamajethi kaphethiloli avaliwe, ukwehluleka kubonakala ekusebenzeni kwenjini yangaphakathi yomlilo.

imoto jerks ngenkathi ushayela, kanye nokusheshisa okuvilaphayo ngokucindezela "okubushelelezi" kwe-"gesi" kuvame ukuvusa izinga eliphansi likaphethiloli ngokulungiswa okungalungile kwesistimu ye-float. Ukunyakaziswa, ukucwiliswa kanye nokujeziswa kwemoto kuyizinto ezivamile ngaphansi kwemithwalo eyengeziwe, enyamalala lapho ushintshela ekugijimeni okubandayo. imvamisa, zihlotshaniswa nokuphazamiseka ohlelweni lokuphakelwa kukaphethiloli, kanye nezici ezilandelayo:

• Ama-valve epompo yesibaseli awaqinile;
• Izihlungi ze-mesh ze-fuel intake kanye ne-carburetor zivaliwe;

Ukucwilisa ngokucindezela okubukhali "kwegesi", enyamalalayo lapho injini evuthayo yangaphakathi yemoto isebenza imizuzwana emihlanu, kumodi efanayo ingase ibangelwe ukuwohloka kwepompo ye-accelerator.
