Vaz-2107 injector: petrol. Yikuphi okungcono - the carburetor noma injector?

Ngemoto Vaz-2107 injector petrol incike nemingcele eziningi. Yiqiniso, wombuso elikhulu ukubaluleka injini - ubukhulu kokucindezelwa, ezingeni zokukhandleka we pistons, amasongo, ama-valve futhi izihlalo zabo, kanye nezinye izingxenye. Kodwa akukhona nje ukuthi nomthelela uphethiloli ukusetshenziswa. Iqiniso ukuthi injector uhlelo fuel umjovo is lwama-computer ngokuphelele. Yiqiniso, kulawulwa nokudlala bekhompuyutha super-yesimanje, kodwa kuphela ngokuthembela microprocessor. Kodwa lokhu kwanele lenhlangano motor umsebenzi ngendlela efanele. Ukuze ufunde mayelana zonke emihle nemibi uhlelo injector fuel injection, kubalulekile ukuba ukuyihlola kabanzi.

Ukwakhiwa jikelele injector fuel uhlelo umjovo

Uhlelo lokuqala lomjovo oqondile uvele emashumini ambalwa eminyaka edlule. Ngeke nje kuphela ukwehlisa fuel oluyisisekelo izimoto, kodwa futhi kakhulu lula ekuphathweni imoto. Nokho, ubunkimbinkimbi design ngesikhathi esifanayo kunyuke - kukhona izinzwa eziningi actuators, engewona nokho esivela carburetor. Ukwethulwa kwalamazwi izinhlelo okuye kwafezwa sibonga kuphela ekuthuthukiseni Microelectronics. Njengoba kusekelwe control unit okuyinto ihlaziya amasignali zonke izinkulungwane yesibili.

Cabanga nje ukuthi pulses eziningi ukhiqiza inzwa eyodwa kuphela? Amakhulu ngomzuzwana, futhi eziningi. Ngaphezu kwalokho, sonke kudingeka ukuhlaziywa kanye kahle phendula them. Kodwa uma carbs abasebenza kuphela ngesisekelo izinqubo elula somzimba, njengokushaya umehluko kwengcindezi kwamakamelo, i-injector sisebenza kuphela ngokusebenzisa izinto zobuchwepheshe. Ingcindezi akuyona ngenxa dilution we-rail ngokujova fuel futhi umoya kuwo. Lokhu kuzoxoxwa ngakho kancane ephansi, kodwa futhi khumbula ukuthi kungcono - i injector noma carburetor imoto yohlobo lwesikhombisa.

I electronic control unit

Bala lo is inhliziyo noma yimuphi umshini umjovo. Ukuze uqonde ukusebenza yayo, kubalulekile ukuba sicabangele umdwebo block kuhlanganisa:

1. amadivaysi Ukufunda (izinzwa).
2. Actuators (IAC, uphethiloli futha, a katkollektora heater).
3. I microcontroller nge nenombolo ledzingekako okokufaka-okukhipha nezimbobo.

Kodwa inkinga bonke yokuthi izinzwa ukunikeza izimpawu ezihlukahlukene. Ngesinye okukhipha 12 volts, kanti eyesibili - engaphansi. Futhi Inkinga iwukuthi ngezinye 2107 injector petrol kuzoncika imingcele wathola kusukela izinzwa kanye microcontroller babone kuphela isibonakaliso uhla 3.5-5 Volt.

Ukufaniswa izinzwa kuya microcontroller

Ngenxa yalokho, yimuphi kudingeka zandisa amasignali, kuyilapho abanye kuncishiswe it. Ngenxa yalezi zinjongo izigaba Lesisemkhatsini (idivayisi ezifanayo) - yokukhulisa umsindo wokusebenza kanye voltage abahlukanisi. Nale ecacile zonke, kodwa microprocessor ngeke bakwazi ukwenza ngisho iinthombe kagesi edluliselwe ikhoyili. Ngenxa yale njongo, emhlanganweni okhethekile Darlington esetshenziswa. Lena chip encane, kusekelwe okhulisa izigaba FET. Zisebenza imodi ukhiye bese uvumele ukushintshela imisinga-30 A, nokuthi kwanele amandla ikhoyili i injector kagesi.

Ukuvumelanisa ne microcontroller akukwazi Jets usebenzisa udlulisela kagesi. Isizathu salokhu - okusezingeni eliphezulu ishayela imvamisa. Edluliselwe nje akakwazi ukuphatha ukufeza inani elidingekayo ukushintsha imisebenzi ngomzuzwana. Kule ngombono, isihluthulelo FET esebenza kahle kakhulu kangakanani.

Okokhelekayo wesitimela

Egibele ngqo iyunithi injini, obhekene ujova uphethiloli emoyeni ingxube ekamelweni omlilo - futhi eya Imibhobho esemzimbeni. On Vaz-2107 injector petrol kuxhomeke ekutheni ukufunde kahle kangakanani umoya exutshwe siwumpompe. Kodwa le nqubo ithatha indawo ncamashi kummango. It is injected ngaphansi kwengcindezi uphethiloli. Umoya odlula lemifanekiso air, ukusivumela luhamba luye ohlangothini olulodwa. Ngaphezu kwalokho, ingxenye kufanele kube enhle - izingxenye 14 emoyeni futhi esisodwa kuphela ingxenye uphethiloli.

Solenoid injectors

Ngezansi ithebula petrol ngoba injini nge umthamo 1.5 amalitha, kodwa nge ezahlukene uhlelo umjovo. Kumpambuko igcina ingcindezi engapheli, nophethiloli imiswe okwesikhashana, cishe uhlobo inkungu. Ehlukanisa ke kusukela amandla omlilo ekamelweni kagesi kuphela injector valve. Kuyini kule divayisi? Siqukethe ikhoyili, core kanye valve okuyinto eliqhutshwa zamanje. I carburetors into efanayo iyatholakala, umklamo kuyafana - valve Solenoid ka idling. Umsebenzi kanye nokubukeka, yebo, ezahlukene. Ingabe injectors babe ezimbili uthi - ovulekile futhi ivaliwe. Eyokuqala umjovo fuel kwenzeka nge emoyeni ekamelweni amandla omlilo.

Electric fuel futha

Futhi nangu nedivaysi wemfanelo wokuqinisekisa ukuthi kukhona njalo ingcindezi ezidingekayo kule wesitimela. Ukuze uthole ukwaziswa mayelana nendlela ukunciphisa petrol, kuzoxoxwa ngezansi. Kodwa-ke Kuyaphawuleka ukuthi le ndlela akuphazamisi futha kagesi. Itholakala ngqo ethangini okuhlanganiswe e umzimba owodwa uphethiloli ezingeni inzwa. Kukhona isisefo ke. Ngo abantu libizwa ngokuthi "inabukeni" ngoba zifana.

By the way, zama ukuyiguqula kaningi ngangokunokwenzeka, kungenjalo ngeke avimbekile fuel imigqa injectors. A yokuhlanza kubiza imali eningi ngezinye izikhathi. Ngaphezu futha kagesi, kukhona enye idivayisi evumela ukuba ulondoloze ingcindezi engapheli - Umlawuli kwisiphambukisi. Ngalo Ziyazisetha fuel ngokweqile emuva ethangini. Ngenxa yalokho, ingcindezi ngokweqile akuyona abasabayo ohlelweni.

I injector kungcono noma okubi kakhulu ukwedlula carburetor?

Lula - lena Inzuzo enkulu ohlelweni injector fuel injection. Ngaphezu kwalokho, it has a okungenani petrol lingaphansi kakhulu kunaleyo carburetor. Isizathu salokho - uhlelo okuthuthukile, kokulawulwa zonke kwemigomo injini. Zikhona izinzuzo - akukho ukuvuza. air supply wahlanganyela ohlelweni electronic. Ngesivinini, injini ukusheshisa ephakeme.

Kodwa ngesivinini aphansi, ngeshwa, isikhathi namandla ingezansi. Kuyinto design iyinkimbinkimbi akuhileli isevisi ezibizayo. Ngaphandle uphethwe ngesinye isikhathi kunzima kutholakale imbangela yokushona iloli imoto. Ngisho zonke lezi idatha kwanele zizozama ukuphendula lo mbuzo, lokho kungcono - i injector noma carburetor. Kodwa impendulo yokugcina namanje ngeke. Ngakolunye uhlangothi, i-injector kungcono. Futhi ngakolunye ke kancane nakakhulu.

Ingabe kungenzeka ukunciphisa ukusetshenziswa kwe-injector?

Futhi manje-ke ukukhuluma indlela yokunciphisa petrol by injini uphethiloli injected. Indlela engcono - ukushintsha firmware microcontroller. Ngakho entsha egcinwe kumephu fuel lapho injini isebenza. Okuqukethwe zikaphethiloli emoyeni kulesi simo izinguquko, ngakho-ke, amandla ukulahlekelwa kwenzeka. Kodwa uthola inzuzo okuncane. Ngenxa manipulations enjalo 2107 injector petrol sinciphile. Nokho, ijubane esiphezulu, amandla kanye ukusheshisa imoto futhi lincipha. abanikazi Car ekukhetheni firmware uholwe ezomhlaba, abalwe ethebuleni. Ukuze uqhathanise, idatha ethulwa kwi injini obufanayo uhlelo carburetor fuel injection.
