Konstruksi Dan Proses Delivery Fuel Di Dalam Fuel Injection Pump

Sahabat teknisi, kembali lagi ke topik masalah engine, kali ini saya akan melanjutkan pembahasan pada postingan sebelumnya tentang fuel injection pump.
• Struktur dan cara kerja pompa injeksi tipe in-line
Semua model dari pompa injeksi bahan bakar pada dasarnya memilki struktur dan cara kerja
yang sama. Berikut ini akan ditunjukkan beberapa contoh struktur dan cara kerja dari beberapa
model pompa injeksi bahan bakar model A, model B, dan model P).

- Proses pengiriman bahan bakar
Rangkaian komponen yang terdiri atas plunger dan plunger barrel dinamakan dengan elemen pompa (pump element). Di atas telah ditunjukkan berbagai macam tipe pump element dari pompa injeksi bahan bakar.

Plunger akan bergerak naik dan turun untuk mensupali bahan bakar. Plunger bergerak naik dan turun setiap satu kali gerakan camshaft. Tingginya pergerakkan dari plunger selalu tetap (berdasrkan camlift).
Struktur plunger dan plunger barrel harus sangat presisi, sehingga mampu mengirimkan bahan bakar ke nozzle dengan tekanan yang cukup tinggi. Pergerakkan dari plunger ditunjukkan pada gambar di atas, baik pada pump element model A maupun model P memeilki prinsip kerja yang sama. Bahan bakar masuk dan keluar melalui lubang inlet/outlet port. Konstruksi plunger barrel tetap (fix) ke rumah pompa injeksi (pump housing). Plunger mengatur pengiriman jumlah bahan bakar (injection rate) dengan berputar. Perputaran dari plunger diatur oleh control rack (model A dan B) atau control rod (model P).
