Nozel Mesin Mobil, Nozel Mesin, Prinsip Kerja

Nozzle otomotif adalah perangkat yang bertanggung jawab untuk penyemprotan bahan bakar langsung di dalam ruang pembakaran. Hingga saat ini, ada beberapa modifikasi perangkat ini. Tentang ini lebih lanjut dalam artikel.

Tergantung pada perangkat yang digunakan untuk mencampur udara dan bahan bakar, ada tiga jenis sistem bahan bakar:

  1. Sistem bahan bakar yang dapat diisi ulang - digunakan di mesin diesel.

  2. Sistem bahan bakar karburator - digunakan dalam motor karburator.

  3. Sistem bahan bakar injektor - digunakan di mesin bensin. Dalam hal ini, untuk pencampuran udara dan bahan bakar bertanggung jawab atas nozzle.

Injeksi langsung atau untuk apa yang Anda butuhkan nozel di mesin

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Injeksi langsung adalah modifulasi injeksi bahan bakar terdistribusi, di mana bahan bakar disuntikkan ke dalam silinder secara langsung. Nozzle adalah komponen pengikat utama antara pompa bahan bakar dan mesin. Tujuan utama nozel:
004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

  1. Memastikan dosis bahan bakar yang benar dipasok ke motor.
  2. Memastikan jet yang benar (kuantitas, tekanan, sudut) campuran.

Nozzle elektromagnetik, perangkat dan prinsip kerja

Perangkat elektromagnetik tersebut digunakan, sebagai aturan, pada mesin bensin, termasuk dengan injeksi langsung. Jenis peralatan ini memiliki desain yang cukup sederhana yang terdiri dari:

  1. Nozzle nozzle.

  2. Jarum.
  3. Segel pada kasing.
  4. Perumahan nosel.
  5. Jangkar dari elektromagnet.
  6. Musim semi khusus.
  7. Berliku eksitasi elektromagnetik.
  8. Konektor listrik.
  9. Filter mesh.
    004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Nozzle melakukan percikan bahan bakar. Dari kualitas pengoperasian komponen ini tergantung pada operasi seluruh perangkat. Filter mesh menyaring bahan bakar yang melewati nozzle.

ECU, sesuai dengan algoritma yang sebelumnya diletakkan, pada saat yang diperlukan memastikan pasokan voltase ke belitan eksitasi katup. Dalam proses ini, medan elektromagnetik terjadi, mengatasi kekuatan pegas, setelah itu menunda jangkar dengan jarum, yang membebaskan nozzle. Setelah semua ini adalah injeksi bahan bakar. Ketika tegangan menghilang, jarum nozzle kembali ke sadel menggunakan pegas.

Nozzle diesel, nozel mesin diesel, perangkat dan prinsip operasi

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Di mesin diesel, termasuk yang dilengkapi dengan sistem injeksi "common rail", nozel elektrohidrolik digunakan. Desain perangkat ini mencakup katup elektromagnetik, ruang kontrol, serta saluran pembuangan dan asupan.

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Prinsip pengoperasian peralatan tersebut didasarkan pada penggunaan tekanan bahan bakar selama injeksi, serta, setelah penghentiannya. Pada posisi awal, katup solenoid benar-benar tertutup dan de-energized, jarum perangkat ditekan ke pelana dengan tekanan pada piston bahan bakar di ruang kontrol. Injeksi bahan bakar dalam posisi ini tidak dilakukan. Perlu dicatat bahwa tekanan bahan bakar pada jarum, dalam situasi ini, lebih sedikit tekanan, yang diproduksi pada piston, sebagai hasil dari perbedaan di daerah kontak.

Setelah perintah ECU, solenoid valve dipicu dan throttle drain dibuka. Bahan bakar, yang terletak di ruang kontrol, sambil mengalir melalui throttle ke jalan raya. Asupan Choke adalah hambatan untuk leveling tekanan tercepat dalam garis saluran masuk dan ruang kontrol. Namun, secara bertahap ada penurunan tekanan pada piston, namun, tekanan bahan bakar yang dilakukan pada jarum tidak berubah, mengakibatkan peningkatan jarum dan injeksi bahan bakar.

Piezohoroforsunk, prinsip kerja

Pengoperasian katup kontrol nozzle didasarkan pada efek piezoelektrik terkenal yang digunakan, misalnya, dalam pemantik gas. Jari pria menekan tombol yang merusak komponen kerja dari dielektrik. Akibatnya, muatan yang digunakan untuk berkaitan dengan gas.

Dalam nozel piezoelektrik, t. N. Membalikkan efek piezoelektrik. Tegangan diumpankan ke dielektrik, yang berkontribusi pada deformasi material. Batang katup terhubung ke sana, yang mampu memanjat jika arus dimasukkan ke nozzle.

Piezohoroforsunk, martabat

004 (1) Knowuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuguuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

  1. Nozel efisiensi tinggi.
  2. Mengurangi kebisingan dalam proses operasi motor.
  3. Kemampuan untuk mengubah tekanan injeksi.
  4. Tingkatkan kecepatan nozzle.
