Kungani imoto ene-carburetor stall uma ucindezela i-gas pedal

Ku-carburetor, lo mphumela ubonakala kuqala ngamashubhu e-emulsion, akhiqiza ukuxuba okuyinhloko kwamafutha nomoya ngezilinganiso ezithile.

Naphezu kweqiniso lokuthi izimoto ezinezinjini ze-carburetor ziye zayeka isikhathi eside, amakhulu ezinkulungwane, uma kungenjalo izigidi zezimoto ezinjalo zisahamba emigwaqweni yaseRussia. Futhi wonke umnikazi wemoto enjalo kufanele azi ukuthi yini okufanele ayenze uma imoto ene-carburetor ithengisa lapho ucindezela igesi.

Isebenza kanjani i-carburetor

Ukusebenza kwalo mshini kusekelwe enqubweni eyatholwa isazi sesayensi yemvelo sase-Italy u-Giovanni Venturi futhi yaqanjwa ngaye - umoya odlula eduze komngcele woketshezi udonsa izinhlayiya zawo kanye nalo. Ku-carburetor, lo mphumela ubonakala kuqala ngamashubhu e-emulsion, akhiqiza ukuxuba okuyinhloko kwamafutha nomoya ngezilinganiso ezithile, bese kuba ku-diffuser, lapho i-emulsion ixubene nokusakaza komoya odlulayo.

Ishubhu ye-Venturi, okuyi-diffuser noma i-emulsion tube, isebenza ngempumelelo kuphela ngesivinini esithile somoya. Ngakho-ke, i-carburetor ifakwe izinhlelo ezengeziwe ezijwayele ukwakheka kwengxube ye-air-fuel kumodi ehlukene yokusebenza kwenjini.

Idivayisi ye-Carburetor

I-carburetor isebenza ngempumelelo kuphela lapho zonke izingxenye zayo, kanye nayo yonke injini, isesimweni esihle futhi ishuniwe. Noma yikuphi ukungasebenzi kahle kuholela ekushintsheni ekubunjweni kwengxube ye-air-fuel, eshintsha izinga lokuvutha nokuvutha kwayo, kanye nenani lamagesi okukhipha amandla akhishwe ngenxa yomlilo. La magesi aphusha i-piston bese kuthi ezintanjeni ezixhumayo azungezisa u-crankshaft, wona, aguqule amandla okunyakaza kwawo abe amandla ajikelezayo kanye ne-torque.

I-carburetor yingxenye ethile yemoto. Uma kwenzeka ukuphuka, kungabangela ukungenzi lutho ukuntanta, kudinga amasu akhethekile okuqalisa, futhi kuholele ekunyakazeni kokunyakaza.

Kungani injini ye-carburetor ithengisa

Isimiso sokusebenza kwenjini yemoto, kungakhathaliseki ukuthi hlobo luni lukaphethiloli nendlela yokunikezwa kwayo, iyafana: ukungena kumasilinda ngama-valve okungenisa, ingxube ye-air-fuel iyasha, ikhiphe amagesi okukhipha umoya. Ivolumu yabo inkulu kangangokuthi ingcindezi ku-cylinder iyanda, ngenxa yokuthi i-piston iqhubekela ku-crankshaft futhi iyiphendule. Ifika endaweni ephansi efile (BDC), i-piston iqala ukunyuka, futhi ama-valve okukhipha amandla avuliwe - imikhiqizo evuthayo ishiya isilinda. Lezi zinqubo zenzeka ezinjini zanoma yiluphi uhlobo, ngakho-ke ngokuqhubekayo sizokhuluma kuphela ngezizathu nokungasebenzi kahle lapho umshini we-carburetor ugcina khona ekuhambeni.

Ukungasebenzi kahle kwesistimu yokubasa

Izimoto ezifakwe i-carburetor zazinezinhlobo ezimbili zezinhlelo zokuthungela:

• othintana naye;
• ngaphandle kokuthintwa.

Imininingwane

Kuhlelo lokuxhumana, ukukhuphuka kwe-voltage okudingekayo ekubunjweni kwenhlansi kwakhiwa ngesikhathi sokuphumula koxhumana nabo abaxhunywe kwizindlu zokusabalalisa kanye ne-shaft ejikelezayo. Ukusonteka okuyinhloko kwekhoyili yokuthungela kuxhunywe unomphela ebhethrini, ngakho-ke lapho othintana naye enqamuka, wonke amandla agcinwe kuyo aphenduka abe ukuqhuma okunamandla kwe-electromotive force (EMF), okuholela ekuqhumeni kwe-voltage kumajika esibili. I-engeli ye-ignition advance (UOZ) isethwe ngokuphendula umsabalalisi. Ngenxa yalo mklamo, abathintwayo kanye nesistimu yokulungisa imishini ye-SPD yizingxenye ezisengozini kakhulu.

Isistimu yokuthungela yokuxhumana - ukubuka kwangaphakathi

Ukukhishwa kwekhoyili kuxhunywe kukhava yomsabalalisi we-distributor, lapho ixhunywe khona kusilayidi ngokusebenzisa isiphethu kanye nokuxhumana kwekhabhoni. Isilayidi esifakwe ku-shaft distributor sidlula othintana nabo besilinda ngasinye: ngesikhathi sokukhishwa kwekhoyili, kwakhiwa isekethe phakathi kwayo ne-spark plug.

Okungaxhunyanwa nabo

Kuhlelo olungenakuxhumana, i-camshaft yekhanda le-cylinder (ikhanda le-cylinder) lixhunywe ku-shaft distributor, lapho ikhethini elinama-slots lifakwe, inani elihambisana nenani lamasilinda. Inzwa yeHholo (inductor) ifakwe endlini yokusabalalisa. Lapho injini isebenza, i-camshaft izungeza i-shaft yokusabalalisa, ngenxa yokuthi amakhethini amakhethini adlula inzwa futhi enze ama-voltage low-voltage pulses kuwo.

Isistimu yokubasa ngaphandle kokuthinta ihlakaziwe

Lawa ma-pulse anikezwa i-transistor switch, okuwanika amandla anele okushaja ikhoyili bese kwakheka inhlansi. I-vacuum ignition corrector ifakwe kumsabalalisi, oshintsha i-UOZ kuye ngemodi yokusebenza yeyunithi yamandla. Ngaphezu kwalokho, i-UOZ yokuqala isethwe ngokuguqula isihlobo se-distributor nekhanda le-cylinder. Ukusatshalaliswa kwamandla kagesi aphezulu kwenzeka ngendlela efanayo nakumasistimu okushisa othintana naye.

Isekhethi yokuthungela ongathintwayo ayihlukile kangako koxhumene naye. Umehluko yinzwa ye-pulse, kanye ne-transistor switch.

• Izinga likaphethiloli egunjini le-float alisethiwe ngokungalungile.

Ukuxazulula inkinga yesiqalo esibi esibandayo

Ulwazi oluthe xaxa mayelana nalawa maphutha kanye nendlela yokuwalungisa lungatholakala lapha (Izitebele zezimoto uma kubanda).

Iqala kabi futhi izitebele lapho kushisa

Uma injini ebandayo iqala kalula, kodwa ngemva kokufudumala, njengoba abashayeli bethi, "kushisa", ilahlekelwa amandla noma izitolo, futhi iqala kabi, khona-ke nazi izizathu ezingenzeka:

• izinga lamafutha elingalungile ekamelweni lokuntanta;
• ukuvuza komoya;
• ukulungiswa okungalungile kokubunjwa kwengxube ngezikrini zekhwalithi nobuningi;
• ukubilisa uphethiloli ku-carburetor;
• ukuthintana okunyamalalayo ngenxa yokwanda kokushisa.

Uma injini ingaphelelwa amandla, kodwa ngemva kokufudumala ayizinzile ngokungenzi lutho, khona-ke uhlelo lwe-XX carburetor cishe lunephutha, ngoba ukufudumala kwenziwa ngemodi yokudonsa, futhi inikeza ukuvula i-throttle nomoya ukunyakaza. ukweqa uhlelo lwe-XX. Uzothola ulwazi oluningiliziwe ngezimbangela zokungasebenzi kahle nezindlela zokulungisa lapha (Izitezi ezishisayo).

Ukulungiswa okungalungile kwe-XX ngekhwalithi kanye nezikulufu zobuningi kuyimbangela evame kakhulu yokungasebenzi kahle.

I-XX engazinzile kuzo zonke izindlela

Uma imoto igcina ingenzi lutho, kodwa injini ayizange ilahlekelwe amandla nokuphendula kwe-throttle, futhi ukusetshenziswa kukaphethiloli kuye kwahlala ezingeni elifanayo, khona-ke i-carburetor cishe ihlale inecala, noma kunalokho isimo sayo sobuchwepheshe. Futhi cishe njalo ukungcola ohlelweni lwe-XX, noma ukulungiswa okungalungile kwale parameter. Uma, ngaphezu kokungenzi kahle, umshini ulahlekelwa amandla noma ezinye izinkinga zivela, khona-ke ukuxilongwa okuphelele kweyunithi yamandla kanye nesistimu kaphethiloli kuyadingeka. Funda kabanzi ngakho konke lokhu lapha (Imoto ihlezi ingenzi lutho).

Injini ayisebenzi

Iyathula uma ucindezela igesi

Uma imoto igxilile lapho ucindezela igesi, kungakhathaliseki ukuthi inaluphi uhlobo lwe-carburetor, i-Solex, i-Ozone noma enye, isheke elilula libalulekile. Nalu uhlu lwezizathu ezingaba khona:

• i-UOZ engalungile;
• i-vacuum ignition corrector enesici;
• ukuvuza komoya;
• ipompo le-accelerator elingalungile.

Isikhathi lapho injini izima kungazelelwe uma ucindezela igesi asijabulisi ngokwedlulele futhi ngokuvamile siyammangaza umshayeli. Akunakwenzeka ukuthi kuzokwazi ukuqonda ngokushesha isizathu salokhu kuziphatha kwemoto.

Ulwazi olwengeziwe lungatholakala lapha (Amatafula ohambeni).

Izitebele lapho ukhulula i-pedal yegesi noma ubhuleka injini

Uma imoto, ngokwesibonelo, i-Niva carburetor, ihamba lapho kukhishwa i-gas pedal, khona-ke izizathu zalokhu kuziphatha zihlobene nokungasebenzi kahle kwesistimu ye-idling, kuhlanganise ne-EPHH, ephazamisa ukunikezwa kukaphethiloli lapho injini. ibhuleki. Ngokuphuma okubukhali kwegesi, i-carburetor kancane kancane ingena kwimodi yokungenzi lutho, ngakho-ke noma iyiphi inkinga ohlelweni lwe-idling iholela ekunikezeni okunganele kwaphethiloli kuyunithi yamandla.

Uma ibhuleki imoto nge injini, okungukuthi, iqhubekela phansi egiyeni, kodwa igesi ikhululwe ngokuphelele, khona-ke EPHH ivimbela ukunikezwa kukaphethiloli, kodwa ngokushesha ngemva kokucindezela i-accelerator, i-economizer kufanele iqalise kabusha ukugeleza kukaphethiloli. Ukuqandisa kwe-valve, kanye nokungcoliswa kwendiza yayo, kuholela eqinisweni lokuthi ngemva kokucindezela igesi, injini ayiqali ngokushesha, noma ingavuli nhlobo, uma lokhu kwenzeka emgwaqeni wezintaba omazombezombe, bese kuba namathuba amaningi okuba nesimo esiphuthumayo.

vala i-valve enjinini

Kumshayeli ongenalwazi, lesi simo sivame ukubukeka kanjena - ucindezela igesi kanye nemoto enezitezi ze-carburetor, akukho jerk okulindelekile noma ukusheshisa okubushelelezi (kuye ngokuthi imingcele eminingi), okwenza umuntu ongemuva kwesondo alahleke futhi angase. wenze iphutha.

Funda futhi: Indlela yokubeka ipompo eyengeziwe esitofu semoto, kungani idingeka

Sincoma ukuthi uthembele ochwepheshe ukuthi bahlanze uhlelo lwe-XX carburetor, ngoba noma yiliphi iphutha lingashubisa isimo nakakhulu.

isiphetho

Uma, lapho ucindezela igesi, imoto enezitezi ze-carburetor, khona-ke isimo sezobuchwepheshe semoto sishiya into efiselekayo: sincoma ngokushesha ukuxilonga injini kanye nesistimu yayo yamafutha. Ungalibali ngokuxilonga uma ezinye izinkinga zenzeka, indlela eyodwa noma enye ehlobene nokungasebenzi kahle kwe-carburetor, ngaphandle kwalokho imoto ingase ihlale endaweni eneshwa kakhulu.

Ukwehluleka lapho ucindezela igesi! Buka yonke into! Ukushoda kwe-UOS!
