Injin injectors

Injector mai (TF), ko injector, yana nufin cikakkun bayanai na tsarin allurar mai. Yana sarrafa sashi da samar da mai da man shafawa, sannan ana fesa su a cikin ɗakin konewa da haɗawa da iska zuwa gauraya guda ɗaya.

TFs suna aiki a matsayin manyan hukumomin zartarwa masu alaƙa da tsarin allura. Godiya ga su, an fesa man fetur a cikin ƙananan ƙwayoyin cuta kuma ya shiga cikin injin. Nozzles na kowane nau'in injin suna aiki iri ɗaya, amma sun bambanta a cikin ƙira da ƙa'idar aiki.

Injectors na mai

Wannan nau'in samfurin yana da alaƙa da samarwa mutum ɗaya don takamaiman nau'in rukunin wutar lantarki. A takaice dai, babu samfurin duniya na wannan na'ura, don haka ba shi yiwuwa a sake shirya su daga injin mai zuwa dizal. A matsayin ban da, za mu iya buga misali na injiniyoyin injiniyoyi daga BOSCH, wanda aka sanya akan tsarin injinan aiki tare da ci gaba da allura. Ana amfani da su sosai don raka'o'in wutar lantarki daban-daban azaman jigon tsarin K-Jetronic, kodayake suna da gyare-gyare daban-daban waɗanda ba su da alaƙa da juna.

Matsayi da ka'idar aiki

A tsarin tsari, injector shine bawul ɗin solenoid wanda software ke sarrafawa. Yana tabbatar da samar da mai ga silinda a cikin ƙayyadaddun allurai, kuma tsarin allurar da aka shigar yana ƙayyade nau'in samfuran da aka yi amfani da su.

Kamar baki

Ana ba da man fetur zuwa bututun mai a karkashin matsin lamba. A wannan yanayin, sashin kula da injin yana aika abubuwan motsa jiki zuwa injector solenoid, wanda ke fara aikin bawul ɗin allura da ke da alhakin yanayin tashar (buɗe / rufe). Adadin man fetur mai shigowa yana ƙayyade ta tsawon lokacin bugun jini mai shigowa, wanda ke shafar lokacin buɗaɗɗen allura.

Wurin nozzles ya dogara da takamaiman nau'in tsarin allura:

• Rarraba: duk silinda yayi daidai da bututun ƙarfe daban wanda yake a gindin bututun ci da kuma allurar mai da mai.

Kai tsaye - nozzles suna saman bangon silinda, suna ba da allura kai tsaye cikin ɗakin konewa.

Injectors don injunan mai

Injin mai suna sanye da nau'ikan allura masu zuwa:

• Guda ɗaya - isar da mai da ke gaban maƙura.

• Multi-point: da yawa nozzles located a gaban nozzles ne alhakin samar da man fetur da lubricants zuwa cylinders.

TFs suna samar da iskar gas zuwa ɗakin konewa na tashar wutar lantarki, yayin da ƙirar irin waɗannan sassa ba za a iya raba su ba kuma baya samar da gyara. A farashi suna da arha fiye da waɗanda aka sanya akan injunan diesel.

A matsayin wani ɓangare na tabbatar da aiki na yau da kullun na tsarin mai na mota, injectors sukan gaza saboda gurɓatar abubuwan tacewa da ke cikinsu tare da samfuran konewa. Irin wannan ajiya yana toshe tashoshin fesa, wanda ke rushe aikin wani mahimmin abu - bawul ɗin allura kuma ya rushe samar da man fetur zuwa ɗakin konewa.

Injectors don injunan diesel

Ana tabbatar da daidaitaccen tsarin man fetur na injunan dizal ta nau'ikan nozzles guda biyu waɗanda aka sanya akan su:

• Electromagnetic, don ƙa'idar tashi da faɗuwar allura wanda ke da alhakin bawul na musamman.

• Piezoelectric, mai kunna wutan lantarki.

Daidaitaccen saitin injectors, da kuma matakin lalacewa, yana shafar aikin injin diesel, ƙarfin da yake samarwa da kuma adadin man da ake cinyewa.

Mai mota zai iya lura da gazawa ko rashin aiki na allurar diesel ta alamomi da yawa:

Motar ba ta son motsawa kuma tana shan taba.

• Injin motar yana rawar jiki.

Matsaloli da rashin aiki na injin injectors

Don kula da aiki na al'ada na tsarin man fetur, wajibi ne don tsaftace nozzles lokaci-lokaci. A cewar masana, ya kamata a aiwatar da hanyar kowane kilomita dubu 20-30, amma a aikace ana buƙatar irin wannan aikin bayan kilomita dubu 10-15. Hakan na faruwa ne saboda rashin ingancin man fetur, rashin kyawun hanyoyin mota da rashin kula da mota a koyaushe.

Matsalolin da suka fi dacewa tare da allurar kowane nau'i sun haɗa da bayyanar ajiya a bangon sassan, wanda shine sakamakon amfani da ƙananan man fetur. Sakamakon wannan shine bayyanar gurɓata a cikin tsarin samar da ruwa mai ƙonewa da kuma faruwar katsewa a cikin aiki, asarar wutar lantarki, yawan amfani da mai da man shafawa.

Dalilan da suka shafi aikin allurar na iya zama:
