Gasoline futha akusho ukumpompa uphethiloli. Ezinye izinto okungenzeka, izindlela zokuxazulula izinkinga

Izithuthi uphethiloli futha - kudivayisi ukulokhu uphalafini isitshalo lapho kumiswa ingxube fuel kwenzeka. Ngisho kancane yokwehluleka kuholela ukuphazamiseka ekuqhubeni injini, kuyilapho amaphutha abo angathi sina ngokwengeziwe, wena umane akaziqhathululanga.

Kulesi sihloko sizohlola isimo lapho i-futha fuel akusho ukumpompa fuel nhlobo, noma okunyakazisa, kodwa hhayi ngemali lapho kuyadingeka ukuze amandla iyunithi operation okuvamile. Siphinde uyazama ukuqonda izimbangela ukungasebenzi ikakhulukazi amafutha Element futhi nixoxe izindlela zokuzithuthukisa kungenisa ama-Isibonelo ezifuywayo zokukhiqiza imoto carburetor Vaz-2109 futhi Vaz-2114 umjovo.

Yiziphi fuel amaphampu

Izimoto uphethiloli izinjini, kuncike brand, imodeli kanye ukuhlela kabusha kungenziwa ifakwe imiklamo ezahlukene igesi amaphampu. Kodwa zonke zingena ngaphansi kwezigaba ezimbili eziyinhloko: mechanical kagesi kanye. Iningi uphethiloli izinjini ifakwe mechanical amadivayisi fuel yokudla. Uma sithatha 2109 (carburetor), khona-ke ukutshala Kwathi nge diaphragm futha ukukhiqizwa DAAZ. Umehluko omkhulu phakathi kwale divaysi ye - design elula, okuyinto okulula ukuyiqonda ngisho saqala. I carburetor "ayisishiyagalolunye" futha likaphethiloli elise gumbi injini yemoto. Kulula ukuthola phezu ejwayelekile hemispherical bonnet nophethiloli hoses.

umjovo Okokhelekayo izinjini 2114 anemisila isifutho kagesi. Ngesikhathi inhliziyo yendlela aklanywe ngayo liphinde ulwelwesi, kodwa ngokungafani kuya "Mechanics" uphethiloli supply kwedivayisi kwamanethiwekhi izimoto nge umjovo ngokuzenzekelayo fuel, akuzona ngaphansi hood, kodwa ngqo ethangini.

Izimpawu ze-futha uphethiloli

Nomaphi lapho injini awuzange ifakwe imoto yakho, izimpawu ukuthi uphethiloli supply apharathasi akuyona efanayo kanjalo. Lezi zihlanganisa:

1. Ukuwaphendula ukuze umzamo injini isiqalo.
2. Ukwephula ukuzinza amandla eMnyangweni lutho.
3. Ezintathu.
4. amandla nokuncishiswa.

Umklamo we carburetor fuel futha 2109

Ukuze uqonde ukuthi kungani akusho ukumpompa uphethiloli futha 2109 (carburetor), ake sibukeze kafushane oyiyo. Ngakho, "ayisishiyagalolunye" uphethiloli Iyunithi enikeza liqukethe:

• izindlu;
• Ingalo pusher nge ukudonsa ngemishini;
• diaphragm umhlangano;
• isivalo nge valve kanye nokufakwa zokuthola amapayipi amanzi;
• strainer;
• isigwedlo ka ukudonsa mathupha.

Umgomo we operation ye mechanical fuel futha

Gasoline futha eziqhutshwa cam we camshaft okuyinto ushukumisela pusher ohlangothini ovundlile, okubangela reciprocating yayo ukunyakaza. Pusher yena, kuthinta mechanical ingalo ukudonsa, futhi ukhulisa kakade uphinde wehlise induku diaphragm.

Ngakho ngaphakathi kwe-futha fuel ukwakha ingcindezi olusekela ikhava kudivayisi enezinto. Omunye wabo sihamba uphethiloli ngaphakathi, hhayi limazise emuva, kanye nezinye odlulela emgqeni fuel uya carburetor.

Njengoba ubona, umklamo silula, ngakho, ukuze kutholakale imbangela yokushona yokuthi futha fuel akusho ukumpompa, kwanele ukuqaqa futhi uhlole isimo izenzakalo ezivelele.

pusher

Ngenxa yokuthi umzimba akuphazamisi ukusebenza kwe-futha fuel, uma kuyindodana, yebo, alilinyaziwe, kuqale pusher. Lo msuka eyenziwe ngensimbi futhi nje akakwazi aphule. Kodwa ukugqoka - sicela, ikakhulukazi uma akulona yokuqala, futhi uthenge njengoba ezingxenyeni ezihlukene. Kufanele wehlise ubude amamilimitha angu ezimbalwa, futhi futha fuel akusho ukumpompa nophethiloli.

Kunalokho, luyinto okufanele unikina, kodwa amplitude we ukunyakaza diaphragm is kakhulu ziyancipha. Yingakho uhlelo ingcindezi ongaphakeme fuel, futhi ngenxa yalokho, utshwaya imitjhapho injini. Ubude ibhanela pusher DAAZ iphampa - 84 mm. Kukalwa ubude bayo, bese ushintsha bafake izingxenye, uma kunesidingo.

diaphragm

Iphutha ezivamile diaphragm - kuyinto ukudabuka yayo. Kwenzeka futhi ukuthi likhubazeke. Ngenxa yalesi umonakalo uqala ukuba adabule fuel diaphragm ngokwayo, okuyilona elisebenzayo futhi imbangela ingcindezi yokwehla kwezinga ohlelweni.

Ukuthola iphutha elinjalo, kuphela ukuliqaqa idivayisi uphethiloli supply. Uma lokho kungasebenzi ukumpompa uphethiloli futha, diaphragm unecala, uzobona ngokushesha. Thina ukuxazulula le nkinga ngokwenza ulibuyisele.

Mboza nge valve kanye nokufakwa

Kohl uke zezikhali futha fuel, hhayi lazy kakhulu ukuhlola valve. Omunye kumele ake uphethiloli, kanye nezinye - ukukhiqiza. Just nishaye zayiqeda bese usetha, kahle nendlela lezi zinto ezisebenza. Uma ama-valve musa ukubhekana ngokuphumelelayo imisebenzi yabo, ubuyisela ikhava inhlangano.

I futha isigwedlo ka ukudonsa imanuwali

Into yokuqala uzobona ukuqaqa lesi Element nophethiloli - strainer. Wenziwe ngepulasitiki mncane perforated. Isizathu salokho, lesi simo asisho ukumpompa uphethiloli futha, futhi zingaba ke uma kukhona ukusonteka yokungcola kwakhe noma okunzima.

Esimweni sokuqala, lemifanekiso kufanele indawo, okwesibili - uxubha uketshezi ukuhlanza carburetors.

Isigwedlo ka ukudonsa inhlukano yokuthi futha fuel akusho ukumpompa fuel phakathi ukujikeleza camshaft, asihlobene. Into kuphela ongayenza ukuwuchitha - kungcono entwasahlobo, ke Asondele kwindawo kokuqala.

Gasoline futha akusho ukumpompa: injector

Njengoba sesivele okukhulunywa, amaphampu ku carburetor nophethiloli umjovo izinjini abe design ehlukene. Ngo nezimoto bephoqeleka fuel injection zonke izinqubo ezihlobene yiso ekamelweni amandla omlilo, kulawulwa i control unit ngogesi, ngakho kungenzeka khona zokugwema ukuphuka izinhlobo ezihlukahlukene zezindwangu ezingaba amadivayisi ayi- elekhthroniki.

Izizathu eziyinhloko ukuthi futha fuel akusho ukumpompa umjovo engine, kungabandakanya:

• iphutha kudivayisi actuator;
• Hlunga odla futha;
• ukwehluleka edluliselwe;
• fuse kushaywa.

Kanjani ukuqonda imbangela misfire yiso futha fuel

Ukuxilonga izinkinga nge futha likaphethiloli emotweni nge injini uphethiloli injected kulula kakhulu kunezinye imoto nge injini carbureted. Iqiniso lokuthi ngokugqamile wezwa umsindo module motor fuel ne ukuthungela ku. Uthatha imizuzwana embalwa. Lokhu umsindo ibonisa ukuthi futha fuel iphendula, unikina nophethiloli.

Uma lokhu kwenzeka lapho uvula ukhiye ke ngedivayisi ngokwawo Kulungile, futhi isizathu udinga kufanele abheke kwenye indawo. Nokho, uma ukuthungela esitshalweni awukwazi ukuzwa isici umsindo futha, ungaqiniseka - inkinga ke, noma izakhi zalo of ugesi.

Qala nge edluliselwe ne-fuse

Uma sicabangela ukuthi uphethiloli ukulethwa Phiko emotweni ithangi, futhi ungene akusiyo njengoba uphethwe lula kungcono ukuqala edluliselwe ne-fuse:

1. Uyasikrufulula ngezikulufo cap ukuthi uvikelekile block obandayo, elise kwesokunxele ikholomu ayo.
2. Ngaphansi kwakhe ukuthola F3 fuse (15a) kanye edluliselwe-R2. Lawa izakhi ukuthi kudingeka uhlole.
3. Ngokuqondene fuse, kubalulekile ukuba "ping" umhloli. Endabeni unfitness - esikhundleni salo.

Hlola edluliselwe egalaji nzima impela. Kodwa kungenzeka ukuthatha efanayo (esidlekeni engumakhelwane), edluliselwe ezinhle zishunyayelwe, wayibeka endaweni sitholakale. Manje vula ukuthungela. Shakes likaphethiloli futha? Isizathu itholakala! Nokho, uma akukho okushintshile, siya phambili.

idrayivu Electric kanye lemifanekiso

Gasoline futha e inzhetornom 2114 liyisici module fuel, esemgwaqweni ethangini imoto. Amalungu ayo futhi zihlanganisa:

• isihlungi indawo;
• fuel level inzwa;
• uxhumano yokuxhuma nophethiloli.

Ukuze uthole unit, susa Ezansi esihlalweni ezingemuva, unqamule amahanisi Izintambo zikagesi ezisobala kanye ukususa nezikulufi 8 nokubopha ihlanganisa. Susa yonke inhlangano kudivayisi. Okokuqala ahlole strainer. Uma ixhunyiwe, esikhundleni salo.

Ukuhlola motor uzodinga ukuxhuma ngqo terminals ibhethri. Endabeni ka operation evamile, "kwakhala" Izintambo zikagesi ezisobala kanye hlola wire contact isisindo ekhaveni mojuli. Uma injini akukuniki izimpawu zokuphila, futhi ekugcineni umbuzo "kungani ukumpompa uphethiloli futha" ithole isixazululo yayo.

Zama ukulungisa ngokwakho okungalungile. Vele ukuthenga imoto entsha bese ushintsha eyodwa ubudala. Nokho, asikho isidingo ukuchitha imali kwi ukuthengwa yonke module, okuyinto manje ayelingana cishe izinkulungwane 3. Ruble. Thenga ahlukene motor kagesi futhi ukuhlunga okusha. Zonke kuzobiza wena kathathu eshibhile.
