Aliran fuel dari Plunger akan

dialirkan melewati Delivery valve

dimana aliran tersebut tidak bisa

kembali ke plunger lagi.

Cara kerja:


FIP FUEL System Advance Timer


INJECTION NOZZLE

Fuel mengalir melewati Delivery Valve dan masuk kedalam Nozzle.

Nozzle akan otomatis membuka oleh fuel Pressure itu sendiri,

sehingga penginjeksianpun terjadi.

Cara kerja:


INJECTION NOZZLE


INJECTION NOZZLE


WATER SEPARATOR Fungsi : Untuk memisahkan

Fuel dari kandungan Air.

Air yang memiliki berat jenis

lebih besar dari fuel akan

larut ke bagian bawah

Water Separator.

Metode Delivery Valve


Adjusting Injection Timing Mark Methode

1. Posisikan engine pada posisi Top 1 6 (lihat marking pada pulley)

2. Putar balik arah putaran marking pada Pulley hingga marking yang sebelumnya lurus kini harus diatur jaraknya hingga beberapa derajat sebelum TDC (lihat standart pada Shop Manual- Contoh: BTDC 81 pada SAA6D125-3)

3. Kendorkan coupling pada drive shaft to FIP kemudian cocokkan mark pada advance timer hingga lurus.

4. Kemudian kencangkan bolt pada coupling.

Adjusting Injection Timing Delivery valve methode

Ulangi langkah yang kita lakukan pada mark methode hingga pengendoran Coupling.

Buka delivery valve pada fuel injection tube 1 (jika posisi piston pada TOP 1 kompresi)`

Adjusting Injection Timing Delivery valve methode

Ket : 1. Tube 2. Valve holder 3. Spring 4. Delivery valve

Lepaskan Delivery valve kemudian tutup lagi

valve holdernya.

Kemudian lakukan proses Pumping pada

Priming Pump.

Putar Advance

Timer kearah

kanan

Perhatikan saat

Pumping.

Jika Fuel sudah tidak keluar lagi

Pada saat penyesuaian timer walaupun

Dilakukan Pumping, berarti itulah

saat penginjeksiannya.

Pasang delivery Valve

Dan kencangkan Coupling.

TERIMA- KASIH.!!
