3) High Pressure Pipe (Fuel Pipe)
4) Injectors
5) Transfer Pump
6) Fuel Filter Replacement
- Fuel filter change interval: every 30,000 km
- Water separation interval: every 10,000 km (same with engine oil change interval)
- Never reuse the removed fuel filter
ENGINE FUEL SYSTEM
undefined
Fuel line transfers high pressure fuel.
Accordingly, it is made of steel to endure
intermittent high
changes that occur under maximum system
pressure and injection stops. Injection lines
between rail and injectors are all in the same
length; it means the lengths between the rail
and each injector are the same and the
differences in length are compensated by
each bending.
The fuel injection device is composed of
electrical solenoid valve, needle and nozzle
and controlled by engine ECU. The injector
nozzle opens when solenoid valve is
activated to directly inject the fuel into
combustion chamber
injector nozzle is open, remaining fuel after
injection returns to fuel tank through return
line.
Pressure limit valve, fuel returned by low
pressure and fuel used for high pressure
pump lubrication also return to fuel tank
through return line.
The transfer pump is included in the housing
of the high pressure pump. The transfer
pump is the volumetric blade type pump. To
deliver the continuously
volume, the pump transfers fuel from the fuel
tank to high pressure pump.
